The Annexes to this Convention shall constitute an integral part of this Convention.

This Convention shall apply exclusively:

(a) to any damage caused in the territory, including the territorial sea, of a State Party;

(b) to damage by contamination of the environment caused in the exclusive economic zone of a State Party, established in accordance with international law, or, if a State Party has not established such a zone, in an area beyond and adjacent to the territorial sea of that State determined by that State in accordance with international law and extending not more than 200 nautical miles from the baselines from which the breadth of its territorial sea is measured;

(c) to damage, other than damage by contamination of the environment, caused outside the territory, including the territorial sea, of any State, if this damage has been caused by a substance carried on board a ship registered in a State Party or, in the case of an unregistered ship, on board a ship entitled to fly the flag of a State Party; and

(d) to preventive measures, wherever taken.

1. This Convention shall apply to claims, other than claims arising out of any contract for the carriage of goods and passengers, for damage arising from the carriage of hazardous and noxious substances by sea.

2. This Convention shall not apply to the extent that its provisions are incompatible with those of the applicable law relating to workers' compensation or social security schemes.

3. This Convention shall not apply:

(a) to pollution damage as defined in the International Convention on Civil Liability for Oil Pollution Damage, 1969, as amended, whether or not compensation is payable in respect of it under that Convention; and

(b) to damage caused by a radioactive material of class 7 either in the International Maritime Dangerous Goods Code, as amended, or in appendix B of the Code of Safe Practice for Solid Bulk Cargoes, as amended.

4. Except as provided in paragraph 5, the provisions of this Convention shall not apply to warships, naval auxiliary or other ships owned or operated by a State and used, for the time being, only on Government non-commercial service.

5. A State Party may decide to apply this Convention to its war-ships or other vessels described in paragraph 4, in which case it shall notify the Secretary-General thereof specifying the terms and conditions of such application.

6. With respect to ships owned by a State Party and used for commercial purposes, each State shall be subject to suit in the jurisdictions set forth in article 38 and shall waive all defences based on its status as a sovereign State.

1. A State may, at the time of ratification, acceptance, approval of, or accession to, this Convention or any time thereafter, declare that this Convention does not apply to ships;

(a) which do not exceed 200 gross tonnage; and

(b) which carry hazardous and noxious substances only in packaged form; and

(c) while they are engaged on voyages between ports or facilities of that State.

2. Where two neighbouring States agree that this Convention does not apply also to ships which are covered by paragraph 1(a) and (b) while engaged on voyages between ports or facilities of those States, the States concerned may declare that the exclusion from the application of this Convention declared under paragraph 1 covers also ships referred to in this paragraph.

3. Any State which has made the declaration under paragraph 1 or 2 may withdraw such declaration at any time.

4. A declaration made under paragraph 1 or 2, and the withdrawal of the declaration made under paragraph 3, shall be deposited with the Secretary-General who shall, after the entry into force of this Convention, communicate it to the Director.

5. Where a State has made a declaration under paragraph 1 or 2 and has not withdrawn it, hazardous and noxious substances carried on board ships covered by that paragraph shall not be considered to be contributing cargo for the purpose of application of articles 18, 20, article 21, paragraph 5 and article 43.

6. The HNS Fund is not liable to pay compensation for damage caused by substances carried by a ship to which the Convention does not apply pursuant to a declaration made under paragraph 1 or 2, to the extent that:

(a) the damage as defined in article 1, paragraph 6(a), (b) or (c) was caused in:

(i) the territory, including the territorial sea, of the State which has made the declaration, or in the case of neighbouring States which have made a declaration under paragraph 2, of either of them; or

(ii) the exclusive economic zone, or area mentioned in article 3(b), of the State or States referred to in (i);

(b) the damage includes measures taken to prevent or minimise such damage.

Each State Party shall ensure that any obligation arising under this Convention is fulfilled and shall take appropriate measures under its law including the imposing of sanctions as it may deem necessary, with a view to the effective execution of any such obligation.

1. Except as provided in paragraphs 2 and 3, the owner at the time of an incident shall be liable for damage caused by any hazardous and noxious substances in connection with their carriage by sea on board the ship, provided that if an incident consists of a series of occurrences having the same origin the liability shall attach to the owner at the time of the first of such occurrences.

2. No liability shall attach to the owner if the owner proves that:

(a) the damage resulted from an act of war, hostilities, civil war, insurrection or a natural phenomenon of an exceptional, inevitable and irresistible character; or

(b) the damage was wholly caused by an act or omission done with the intent to cause damage by a third party; or

(c) the damage was wholly caused by the negligence or other wrongful act of any Government or other authority responsible for the maintenance of lights or other navigational aids in the exercise of that function; or

(d) the failure of the shipper or any other person to furnish information concerning the hazardous and noxious nature of the substances shipped either

(i) has caused the damage, wholly or partly; or

(ii) has led the owner not to obtain insurance in accordance with article 12;

provided that neither the owner nor its servants or agents knew or ought reasonably to have known of the hazardous and noxious nature of the substances shipped.

3. If the owner proves that the damage resulted wholly or partly either from an act or omission done with intent to cause damage by the person who suffered the damage or from the negligence of that person, the owner may be exonerated wholly or partially from liability to such person.

4. No claim for compensation for damage shall be made against the owner otherwise than in accordance with this Convention.

5. Subject to paragraph 6, no claim for compensation for damage under this Convention or otherwise may be made against:

(a) the servants or agents of the owner or the members of the crew;

(b) the pilot or any other person who, without being a member of the crew, performs services for the ship;

(c) any charterer (howsoever described, including a bareboat charterer), manager or operator of the ship;

(d) any person performing salvage operations with the consent of the owner or on the instructions of a competent public authority;

(e) any person taking preventive measures; and

(f) the servants or agents of persons mentioned in (c), (d) and (e);

unless the damage resulted from their personal act or omission, committed with the intent to cause such damage, or recklessly and with knowledge that such damage would probably result.

6. Nothing in this Convention shall prejudice any existing right of recourse of the owner against any third party, including, but not limited to, the shipper or the receiver of the substance causing the damage, or the persons indicated in paragraph 5.

1. Whenever damage has resulted from an incident involving two or more ships each of which is carrying hazardous and noxious substances, each owner, unless exonerated under article 7, shall be liable for the damage. The owners shall be jointly and severally liable for all such damage which is not reasonably separable.

2. However, owners shall be entitled to the limits of liability applicable to each of them under article 9.

3. Nothing in this article shall prejudice any right of recourse of an owner against any other owner.

1. The owner of a ship shall be entitled to limit liability under this Convention in respect of any one incident to an aggregate amount calculated as follows:

(a) 10 million units of account for a ship not exceeding 2,000 units of tonnage; and

(b) for a ship with a tonnage in excess thereof, the following amount in addition to that mentioned in (a):

for each unit of tonnage from 2,001 to 50,000 units of tonnage, 1,500 units of account;

for each unit of tonnage in excess of 50,000 units of tonnage, 360 units of account;

provided, however, that this aggregate amount shall not in any event exceed 100 million units of account.

2. The owner shall not be entitled to limit liability under this Convention if it is proved that the damage resulted from the personal act or omission of the owner, committed with the intent to cause such damage, or recklessly and with knowlege that such damage would probably result.

3. The owner shall, for the purpose of benefitting from the limitation provided for in paragraph 1, constitute a fund for the total sum representing the limit of liability established in accordance with paragraph 1 with the court or other competent authority of any one of the States Parties in which action is brought under article 38 or, if no action is brought, with any court or other competent authority in any one of the States Parties in which an action can be brought under article 38. The fund can be constituted either by depositing the sum or by producing a bank guarantee or other guarantee, acceptable under the law of the State Party where the fund is constituted, and considered to be adequate by the court or other competent authority.

4. Subject to the provisions of article 11, the fund shall be distributed among the claimants in proportion to the amounts of their established claims.

5. If before the fund is distributed the owner or any of the servants or agents of the owner or any person providing to the owner insurance or other financial security has as a result of the incident in question, paid compensation for damage, such person shall, up to the amount that person has paid, acquire by subrogation the rights which the person so compensated would have enjoyed under this Convention.

6. The right of subrogation provided for in paragraph 5 may also be exercised by a person other than those mentioned therein in respect of any amount of compensation for damage which such person may have paid but only to the extent that such subrogation is permitted under the applicable national law.

7. Where owners or other persons establish that they may be compelled to pay at a later date in whole or in part any such amount of compensation, with regard to which the right of subrogation would have been enjoyed under paragraphs 5 or 6 had the compensation been paid before the fund was distributed, the court or other competent authority of the State where the fund has been constituted may order that a sufficient sum shall be provisionally set aside to enable such person at such later date to enforce the claim against the fund.

8. Claims in respect of expenses reasonably incurred or sacrifices reasonably made by the owner voluntarily to prevent or minimise damage shall rank equally with other claims against the fund.

9. (a) The amounts mentioned in paragraph 1 shall be converted into national currency on the basis of the value of that currency by reference to the Special Drawing Right on the date of the constitution of the fund referred to in paragraph 3. The value of the national currency, in terms of the Special Drawing Right, of a State Party which is a member of the International Monetary Fund, shall be calculated in accordance with the method of valuation applied by the International Monetary Fund in effect on the date in question for its operations and transactions. The value of the national currency, in terms of the Special Drawing Right, of a State Party which is not a member of the International Monetary Fund, shall be calculated in a manner determined by that State.

(b) Nevertheless, a State Party which is not a member of the International Monetary Fund and whose law does not permit the application of the provisions of paragraph 9(a) may, at the time of ratification, acceptance, approval of or accession to this Convention or at any time thereafter, declare that the unit of account referred to in paragraph 9(a) shall be equal to 15 gold francs. The gold franc referred to in this paragraph corresponds to sixty-five-and-a-half milligrammes of gold of millesimal fineness nine hundred. The conversion of the gold franc into the national currency shall be made according to the law of the State concerned.

(c) The calculation mentioned in the last sentence of paragraph 9(a) and the conversion mentioned in paragraph 9(b) shall be made in such manner as to express in the national currency of the State Party as far as possible the same real value for the amounts in paragraph 1 as would result from the application of the first two sentences of paragraph 9(a). States Parties shall communicate to the Secretary-General the manner of calculation pursuant to paragraph 9(a), or the result of the conversion in paragraph 9(b) as the case may be, when depositing an instrument of ratification, acceptance, approval of or accession to this Convention and whenever there is a change in either.

10. For the purpose of this article the ship's tonnage shall be the gross tonnage calculated in accordance with the tonnage measurement regulations contained in Annex I of the International Convention on Tonnage Measurement of Ships, 1969.

11. The insurer or other person providing financial security shall be entitled to constitute a fund in accordance with this article on the same conditions and having the same effect as if it were constituted by the owner. Such a fund may be constituted even if, under the provisions of paragraph 2, the owner is not entitled to limitation of liability, but its constitution shall in that case not prejudice the rights of any claimant against the owner.

1. Where the owner, after an incident, has constituted a fund in accordance with article 9 and is entitled to limit liability:

(a) no person having a claim for damage arising out of that incident shall be entitled to exercise any right against any other assets of the owner in respect of such claim; and

(b) the court or other competent authority of any State Party shall order the release of any ship or other property belonging to the owner which has been arrested in respect of a claim for damage arising out of that incident, and shall similarly release any bail or other security furnished to avoid such arrest.

2. The foregoing shall, however, only apply if the claimant has access to the court administering the fund and the fund is actually available in respect of the claim.

Claims in respect of death or personal injury have priority over other claims save to the extent that the aggregate of such claims exceeds two-thirds of the total amount established in accordance with article 9, paragraph 1.

1. The owner of a ship registered in a State Party and actually carrying hazardous and noxious substances shall be required to maintain insurance or other financial security, such as the guarantee of a bank or similar financial institution, in the sums fixed by applying the limits of liability prescribed in article 9, paragraph 1, to cover liability for damage under this Convention.

2. A compulsory insurance certificate attesting that insurance or other financial security is in force in accordance with the provisions of this Convention shall be issued to each ship after the appropriate authority of a State Party has determined that the requirements of paragraph 1 have been complied with. With respect to a ship registered in a State Party such compulsory insurance certificate shall be issued or certified by the appropriate authority of the State of the ship's registry; with respect to a ship not registered in a State Party it may be issued or certified by the appropriate authority of any State Party. This compulsory insurance certificate shall be in the form of the model set out in Annex I and shall contain the following particulars:

(a) name of the ship, distinctive number or letters and port of registry;

(b) name and principal place of business of the owner;

(c) IMO ship identification number;

(d) type and duration of security;

(e) name and principal place of business of insurer or other person giving security and, where appropriate, place of business where the insurance or security is established; and

(f) period of validity of certificate, which shall not be longer than the period of validity of the insurance or other security.

3. The compulsory insurance certificate shall be in the offical language or languages of the issuing State. If the language used is neither English, nor French nor Spanish, the text shall include a translation into one of these languages.

4. The compulsory insurance certificate shall be carried on board the ship and a copy shall be deposited with the authorities who keep the record of the ship's registry or, if the ship is not registered in a State Party, with the authority of the State issuing or certifying the certificate.

5. An insurance or other financial security shall not satisfy the requirements of this article if it can cease, for reasons other than the expiry of the period of validity of the insurance or security specified in the certificate under paragraph 2, before three months have elapsed from the date on which notice of its termination is given to the authorities referred to in paragraph 4, unless the compulsory insurance certificate has been issued within the said period. The foregoing provisions shall similarly apply to any modification which results in the insurance or security no longer satisfying the requirements of this article.

6. The State of the ship's registry shall, subject to the provisions of this article, determine the conditions of issue and validity of the compulsory insurance certificate.

7. Compulsory insurance certificates issued or certified under the authority of a State Party in accordance with paragraph 2 shall be accepted by other States Parties for the purposes of this Convention and shall be regarded by other States Parties as having the same force as compulsory insurance certificates issued or certified by them even if issued or certified in respect of a ship not registered in a State Party. A State Party may at any time request consultation with the issuing or certifying State should it believe that the insurer or guarantor named in the compulsory insurance certificate is not financially capable of meeting the obligations imposed by this Convention.

8. Any claim for compensation for damage may be brought directly against the insurer or other person providing financial security for the owner's liability for damage. In such case the defendant may, even if the owner is not entitled to limitation of liability, benefit from the limit of liability prescribed in accordance with paragraph 1. The defendant may further invoke the defences (other than the bankruptcy or winding up of the owner) which the owner would have been entitled to invoke. Furthermore, the defendant may invoke the defence that the damage resulted from the wilful misconduct of the owner, but the defendant shall not invoke any other defence which the defendant might have been entitled to invoke in proceedings brought by the owner against the defendant. The defendant shall in any event have the right to require the owner to be joined in the proceedings.

9. Any sums provided by insurance or by other financial security maintained in accordance with paragraph 1 shall be available exclusively for the satisfaction of claims under this Convention.

10. A State Party shall not permit a ship under its flag to which this article applies to trade unless a certificate has been issued under paragraph 2 or 12.

11. Subject to the provisions of this article, each State Party shall ensure, under its national law, that insurance or other security in the sums specified in paragraph 1 is in force in respect of any ship, wherever registered, entering or leaving a port in its territory, or arriving at or leaving an offshore facility in its territorial sea.

12. If insurance or other financial security is not maintained in respect of a ship owned by a State Party, the provisions of this article relating thereto shall not be applicable to such ship, but the ship shall carry a compulsory insurance certificate issued by the appropriate authorities of the State of the ship's registry stating that the ship is owned by that State and that the ship's liability is covered within the limit prescribed in accordance with paragraph 1. Such a compulsory insurance certificate shall follow as closely as possible the model prescribed by paragraph 2.

1. The International Hazardous and Noxious Substances Fund (HNS Fund) is hereby established with the following aims:

(a) to provide compensation for damage in connection with the carriage of hazardous and noxious substances by sea, to the extent that the protection afforded by chapter II is inadequate or not available; and

(b) to give effect to the related tasks set out in article 15.

2. The HNS Fund shall in each State Party be recognized as a legal person capable under the laws of that State of assuming rights and obligations and of being a party in legal proceeding before the courts of that State. Each State Party shall recognize the Director as the legal representative of the HNS Fund.

1. For the purpose of fulfilling its function under article 13, paragraph 1(a), the HNS Fund shall pay compensation to any person suffering damage if such person has been unable to obtain full and adequate compensation for the damage under the terms of Chapter II:

(a) because no liability for the damage arises under Chapter II;

(b) because the owner liable for the damage under Chapter II is financially incapable of meeting the obligations under this Convention in full and any financial security that may be provided under Chapter II does not cover or is insufficient to satisfy the claims for compensation for damage; an owner being treated as financially incapable of meeting these obligations and a financial security being treated as insufficient if the person suffering the damage has been unable to obtain full satisfaction of the amount of compensation due under Chapter II after having taken all reasonable steps to pursue the available legal remedies;

(c) because the damage exceeds the owner's liability under the terms of Chapter II.

2. Expenses reasonably incurred or sacrifices reasonably made by the owner voluntarily to prevent or minimize damage shall be treated as damage for the purposes of this article.

3. The HNS Fund shall incur no obligation under the preceding paragraphs if:

(a) it proves that the damage resulted from an act of war, hostilities, civil war or insurrection or was caused by hazardous and noxious substances which had escaped or been discharged from a warship or other ship owned or operated by a State and used, at the time of the incident, only on Government non-commercial service; or

(b) the claimant cannot prove that there is a reasonable probability that the damage resulted from an incident involving one or more ships.

4. If the HNS Fund proves that the damage resulted wholly or partly either from an act or omission done with intent to cause damage by the person who suffered the damage or from the negligence of that person, the HNS Fund may be exonerated wholly or partially from its obligation to pay compensation to such person. The HNS Fund shall in any event be exonerated to the extent that the owner may have been exonerated under article 7, paragraph 3. However, there shall be no such exoneration of the HNS Fund with regard to preventive measures.

5. (a) Except as otherwise provided in subparagraph (b), the aggregate amount of compensation payable by the HNS Fund under this article shall in respect of any one incident be limited, so that the total sum of that amount and any amount of compensation actually paid under Chapter II for damage within the scope of application of this Convention as defined in article 3 shall not exceed 250 million units of account.

(b) The aggregate amount of compensation payable by the HNS Fund under this article for damage resulting from a natural phenomenon of an exceptional, inevitable and irresistable character shall not exceed 250 million units of account.

(c) Interest accrued on a fund constituted in accordance with article 9, paragraph 3, if any, shall not be taken into account for the computation of the maximum compensation payable by the HNS Fund under this article.

(d) The amounts mentioned in this article shall be converted into national currency on the basis of the value of that currency with reference to the Special Drawing Right on the date of the decision of the Assembly of the HNS Fund as to the first date of payment of compensation.

6. Where the amount of established claims against the HNS Fund exceeds the aggregate amount of compensation payable under paragraph 5, the amount available shall be distributed in such a manner that the proportion between any established claim and the amount of compensation actually recovered by the claimant under this Convention shall be the same for all claimants. Claims in respect of death or personal injury shall have priority over other claims, however, save to the extent that the aggregate of such claims exceeds two-thirds of the total amount established in accordance with paragraph 5.

7. The Assembly of the HNS Fund may decide that, in exceptional cases, compensation in accordance with this Convention can be paid even if the owner has not constituted a fund in accordance with Chapter II. In such cases paragraph 5(d) applies accordingly.

For the purpose of fulfilling its function under article 13, paragraph 1(a), the HNS Fund shall have the following tasks:

(a) to consider claims made against the HNS Fund;

(b) to prepare an estimate in the form of a budget for each calendar year of:

Expenditure:

(i) costs and expenses of the administration of the HNS Fund in the relevant year and any deficit from operations in the preceding years; and

(ii) payments to be made by the HNS Fund in the relevant year;

Income:

(iii) surplus funds from operations in preceding years, including any interest;

(iv) initial contributions to be paid in the course of the year;

(v) annual contributions if required to balance the budget; and

(vi) any other income;

(c) to use at the request of a State Party its good offices as necessary to assist that State to secure promptly such personnel, material and services as are necessary to enable the State to take measures to prevent or mitigate damage arising from an incident in respect of which the HNS Fund may be called upon to pay compensation under this Convention; and

(d) to provide, on conditions laid down in the internal regulations, credit facilities with a view to the taking of preventive measures against damage arising from a particular incident in respect of which the HNS Fund may be called upon to pay compensation under this Convention.

1. The HNS Fund shall have a general account, which shall be divided into sectors.

2. The HNS Fund shall, subject to article 19, paragraphs 3 and 4, also have separate accounts in respect of:

(a) oil as defined in article 1, paragraph 5(a)(i) (oil account);

(b) liquefied natural gases of light hydrocarbons with methane as the main constituent (LNG) (LNG account); and

(c) liquefied petroleum gases of light hydrocarbons with propane and butane as the main constituents (LPG) (LPG account).

3. There shall be initial contributions and, as required, annual contributions to the HNS fund.

4. Contributions to the HNS Fund shall be made into the general account in accordance with article 18, to separate accounts in accordance with article 19 and to either the general account or separate accounts in accordance with article 20 or article 21, paragraph 5. Subject to article 19, paragraph 6, the general account shall be available to compensate damage caused by hazardous and noxious substances covered by that account, and a separate account shall be available to compensate damage caused by a hazardous and noxious substance covered by that account.

5. For the purposes of article 18, article 19, paragraph 1(a)(i), paragraph 1(a)(ii) and paragraph 1(c), article 20 and article 21, paragraph 5, where the quantity of a given type of contributing cargo received in the territory of a State Party by any person in a calendar year when aggregated with the quantities of the same type of cargo received in the same State Party in that year by any associated person or persons exceeds the limit specified in the respective sub-paragraphs, such a person shall pay contributions in respect of the actual quantity received by that person notwithstanding that that quantity did not exceed the respective limit.

6. “Associated person” means any subsidiary or commonly controlled entity. The question whether a person comes within this definition shall be determined by the national law of the State concerned.

1. Annual contributions to the general account and to each separate account shall be levied only as required to make payments by the account in question.

2. Annual contributions payable pursuant to articles 18, 19 and article 21, paragraph 5 shall be determined by the Assembly and shall be calculated in accordance with those articles on the basis of the units of contributing cargo received or, in respect of cargoes referred to in article 19, paragraph 1(b), discharged during the preceding calendar year or such other year as the Assembly may decide.

3. The Assembly shall decide the total amount of annual contributions to be levied to the general account and to each separate account. Following that decision the Director shall, in respect of each State Party, calculate for each person liable to pay contributions in accordance with article 18, article 19, paragraph 1 and article 21, paragraph 5, the amount of that person's annual contribution to each account, on the basis of a fixed sum for each unit of contributing cargo reported in respect of the person during the preceding calendar year or such other year as the Assembly may decide. For the general account, the above-mentioned fixed sum per unit of contributing cargo for each sector shall be calculated pursuant to the regulations contained in Annex II to this Convention. For each separate account, the fixed sum per unit of contributing cargo referred to above shall be calculated by dividing the total annual contribution to be levied to that account by the total quantity of cargo contributing to that account.

4. The Assembly may also levy annual contributions for administrative costs and decide on the distribution of such costs between the sectors of the general account and the separate accounts.

5.

1. Subject to article 16, paragraph 5, annual contributions to the general account shall be made in respect of each State Party by any person who was the receiver in that State in the preceding calendar year, or such other year as the Assembly may decide, of aggregate quantities exceeding 20,000 tonnes of contributing cargo, other than substances referred to in article 19, paragraph 1, which fall within the following sectors:

2. Subject to paragraph 3; the separate accounts referred to in paragraph 1 above shall become effective at the same time as the general account.

3. The initial operation of a separate account referred to in article 16, paragraph 2 shall be postponed until such time as the quantities of contributing cargo in respect of that account during the preceding calendar year, or such other year as the Assembly may decide, exceed the following levels:

(b) when six months have elapsed from the date when the contributions were due, the total unpaid contributions to that account exceed ten per cent of the most recent levy to that account in accordance with paragraph 1.

5. The Assembly may reinstate the operation of a separate account which has been suspended in accordance with paragraph 4.

6. Any person who would be liable to pay contributions to a separate account the operation of which has been postponed in accordance with paragraph 3 or suspended in accordance with paragraph 4, shall pay into the general account the contributions due by that person in respect of that separate account. For the purpose of calculating future contributions, the postponed or suspended separate account shall form a new sector in the general account and shall be subject to the HNS points system defined in Annex II.

1. In respect of each State Party, initial contributions shall be made of an amount which shall for each person liable to pay contributions in accordance with article 16, paragraph 5, articles 18, 19 and article 21, paragraph 5 be calculated in the basis of a fixed sum, equal for the general account and each separate account, for each unit of contributing cargo received or, in the case of LNG, discharged in that State, during the calendar year preceding that in which this Convention enters into force for that State.

2. The fixed sum and the units for the different sectors within the general account as well as for each separate account referred to in paragraph 1 shall be determined by the Assembly.

3. Initial contributions shall be paid within three months following the date on which the HNS Fund issues invoices in respect of each State Party to persons liable to pay contributions in accordance with paragraph 1.

For the purposes set out in paragraph 1, each State Party shall communicate to the Director, at a time and in the manner to be prescribed in the internal regulations of the HNS Fund, the name and address of any person who in respect of the State is liable to pay contributions in accordance with articles 18, 19 or paragraph 5 of this article, as well as data on the relevant quantities of contributing cargo for which such person is liable to contribute in respect of the preceding calendar year.

3. For the purposes of ascertaining who are, at any given time, the persons liable to pay contributions in accordance with articles 18, 19 or paragraph 5 of this article and of establishing, where applicable, the quantities of cargo to be taken into account for any such person when determining the amount of the contribution, the list shall be prima facie evidence of the facts stated therein.

4. Where a State Party does not fulfill its obligations to communicate to the Director the information referred to in paragraph 2 and this results in a financial loss for the HNS Fund, that State Party shall be liable to compensate the HNS Fund for such loss. The Assembly shall, on the recommendation of the Director, decide whether such compensation shall be payable by a State Party.

5. In respect of contributing cargo from one port or terminal of a State Party to another port or terminal located in the same State and discharged there, States Parties shall have the option of submitting to the HNS Fund a report with an annual aggregate quantity for each account covering all receipts of contributing cargo, including any quantities in respect of which contributions are payable pursuant to article 16, paragraph 5. The State Party shall, at the time of reporting, either:

(a) notify the HNS Fund that that State will pay the aggregate amount for each account in respect of the relevant year in one lump sum to the HNS Fund; or

(b) instruct the HNS Fund to levy the aggregate amount for each account by invoicing individual receivers or, in the case of LNG, the title holder who discharges within the jurisdiction of that State Party, for the amount payable by each of them. These persons shall be identified in accordance with the national law of the State concerned.

1. The amount of any contribution due under articles 18, 19, 20 or article 21, paragraph 5 and which is in arrears shall bear interest at a rate which shall be determined in accordance with the internal regulations of the HNS Fund, provided that different rates may be fixed for different circumstances.

2. Where a person who is liable to pay contributions in accordance with articles 18, 19, 20 or article 21, paragraph 5 does not fulfil the obligations in respect of any such contribution or any part thereof and is in arrears, the Director shall take all appropriate action, including court action, against such a person on behalf of the HNS Fund with a view to the recovery of the amount due. However, where the defaulting contributor is manifestly insolvent or the circumstances otherwise so warrant, the Assembly may, upon recommendation of the Director, decide that no action shall be taken or continued against the contributor.

1. Without prejudice to article 21, paragraph 5, a State Party may at the time when it deposits its instrument of ratification, acceptance, approval or accession or at any time thereafter declare that it assumes responsibility for obligations imposed by this Convention on any person liable to pay contributions in accordance with articles 18, 19, 20 or article 21, paragraph 5 in respect of hazardous and noxious substances received or discharged in the territory of that State. Such a declaration shall be made in writing and shall specify which obligations are assumed.

3. A declaration under paragraph 1 which is made after the entry into force of this Convention shall be deposited with the Director.

Subject to the subsequent provisions of this article, any action against the HNS Fund for compensation under article 14 shall be brought only before a court having jurisdiction under article 38 in respect of actions against the owner who is liable for damage caused by the relevant incident or before a court in a State Party which would have been competent if an owner had been liable.

3. Without prejudice to any other rights of subrogation or recourse against the HNS Fund which may exist, a State Party or agency thereof which has paid compensation for damage in accordance with provisions of national law shall acquire by subrogation the rights which the person so compensated would have enjoyed under this Convention.

This Convention shall supersede any convention in force or open for signature, ratification or accession at the date on which this Convention is opened for signature, but only to the extent that such convention would be in conflict with it; however, nothing in this article shall affect the obligations of States Parties to States not party to this Convention arising under such convention.

When depositing an instrument referred to in article 45, paragraph 3, and annually thereafter until this Convention enters into force for a State, that State shall submit to the Secretary-General data on the relevant quantities of contributing cargo received or, in the case of LNG, discharged in that State during the preceding calendar year in respect of the general account and each separate account.

It shall also take into account the relationship between the limits established in article 9, paragraph 1, and those in article 14, paragraph 5.

7. (a) No amendment of the limits under this article may be considered less than five years from the date this Convention was opened for signature nor less than five years from the date of entry into force of a previous amendment under this article.

When an amendment has been adopted but the eighteen month period for its acceptance has not yet expired, a State which becomes a Contracting State during that period shall be bound by the amendment if it enters into force. A State which becomes a Contracting State after that period shall be bound by an amendment which has been accepted in accordance with paragraph 8. In the cases referred to in this paragraph, a State becomes bound by an amendment when that amendment enters into force, or when this Convention enters into force for that State, if later.

The Director shall convene the Assembly to meet not less than sixty days after receipt of the request.

2.

3. If the Assembly, at an extraordinary session, convened in accordance with paragraph 1 or 2 decides that the denunciation will result in a significant increase in the level of contributions from the remaining States Parties, any such State may, not later than one hundred and twenty days before the date on which the denunciation takes effect, denounce this Convention with effect from the same date.

1. This Convention shall cease to be in force:

(a) on the date when the number of States Parties falls below 6; or

(b) twelve months after the date on which data concerning a previous calendar year were to be communicated to the Director in accordance with article 21, if the data shows that the total quantity of contributing cargo to the general account in accordance with article 18, paragraphs 1(a) and (c) received in the States Parties in that preceding calendar year was less than 30 million tonnes.

Notwithstanding (b), if the total quantity of contributing cargo to the general account in accordance with article 18, paragraphs 1(a) and (c) received in the States Parties in the preceding calendar year was less than 30 million tonnes but more than 25 million tonnes, the Assembly may, if it considers that this was due to exceptional circumstances and is not likely to be repeated, decide before the expiry of the above-mentioned twelve month period that the Convention shall continue to be in force. The Assembly may not, however, take such a decision in more than two subsequent years.

(b) oil, if the operation of the oil account is postponed or suspended;

(c) LNG, if the operation of the LNG account is postponed or suspended;

(d) LPG, if the operation of the LPG account is postponed or suspended;

Regulation 2

1. For each sector, the fixed sum per unit of contributing cargo shall be the product of the levy per HNS point and the sector factor for that sector.

2. The levy per HNS point shall be the total annual contributions to be levied to the general account divided by the total HNS points for all sectors.

3. The total HNS points for each sector shall be the product of the total volume, measured in metric tonnes, of contributing cargo for that sector and the corresponding sector factor.

4. A sector factor shall be calculated as the weighted arithmetic average of the claims/volume ratio for that sector for the relevant year and the previous nine years, according to this regulation.

5. Except as provided in paragraph 6, the claims/volume ratio for each of these years shall be calculated as follows:

(a) established claims, measured in units of account converted from the claim currency using the rate applicable on the date of the incident in question, for damage caused by substances in respect of which contributions to the HNS Fund are due for the relevant year; divided by

(b) the volume of contributing cargo corresponding to the relevant year.

7. The arithmetic average of the ten years shall be weighted on a decreasing linear scale, so that the ratio of the relevant year shall have a weight of 10, the year prior to the relevant year shall have a weight of 9, the next preceding year shall have a weight of 8, and so on, until the tenth year has a weight of 1.

8. If the operation of a separate account has been suspended, the relevant sector factor shall be calculated in accordance with those provisions of this regulation which the Assembly shall consider appropriate.
