ARTICLE 31: SPECIAL PROVISIONS RELATING TO INTERNATIONAL TRADE
1. The Parties shall not knowingly permit the export of drugs to any country or territory except:
(a) In accordance with the laws and regulations of that country or territory; and
(b) Within the limits of the total of the estimates for that country or territory, as defined in paragraph 2 of article 19, with the addition of the amounts intended to be re-exported.
2. The Parties shall exercise in free ports and zones the same supervision and control as in other parts of their territories, provided, however, that they may apply more drastic measures.
3. The Parties shall:
(a) Control under licence the import and export of drugs except where such import or export is carried out by a State enterprise or enterprises;
(b) Control all persons and enterprises carrying on or engaged in such import or export.
4.
(a) Every Party permitting the import or export of drugs shall require a separate import or export authorization to be obtained for each such import or export whether it consists of one or more drugs.
(b) Such authorization shall state the name of the drug, the international non-proprietary name if any, the quantity to be imported or exported, and the name and address of the importer and exporter, and shall specify the period within which the importation or exportation must be effected.
(c) The export authorization shall also state the number and date of the import certificate (paragraph 5) and the authority by whom it has been issued.
(d) The import authorization may allow an importation in more than one consignment.
5. Before issuing an export authorization the Parties shall require an import certificate, issued by the competent authorities of the importing country or territory and certifying that the importation of the drug or drugs referred to therein, is approved and such certificate shall be produced by the person or establishment applying for the export authorization. The Parties shall follow as closely as may be practicable the form of import certificate approved by the Commission.
6. A copy of the export authorization shall accompany each consignment, and the Government issuing the export authorization shall send a copy to the Government of the importing country or territory.
7.
(a) The Government of the importing country or territory, when the importation has been effected or when the period fixed for the importation has expired, shall return the export authorization, with an endorsement to that effect, to the Government of the exporting country or territory.
(b) The endorsement shall specify the amount actually imported.
(c) If a lesser quantity than that specified in the export authorization is actually exported, the quantity actually exported shall be stated by the competent authorities on the export authorization and on any official copy thereof.
8. Exports of consignments to a post office box, or to a bank to the account of a Party other than the Party named in the export authorization, shall be prohibited.
9. Exports of consignments to a bonded warehouse are prohibited unless the Government of the importing country certifies on the import certificate, produced by the person or establishment applying for the export authorization, that it has approved the importation for the purpose of being placed in a bonded warehouse. In such case the export authorization shall specify that the consignment is exported for such purpose. Each withdrawal from the bonded warehouse shall require a permit from the authorities having jurisdiction over the warehouse and, in the case of a foreign destination shall be treated as if it were a new export within the meaning of this Convention.
10. Consignments of drugs entering or leaving the territory of a Party not accompanied by an export authorization shall be detained by the competent authorities.
11. A Party shall not permit any drugs consigned to another country to pass through its territory, whether or not the consignment is removed from the conveyance in which it is carried, unless a copy of the export authorization for such consignment is produced to the competent authorities of such Party.
12. The competent authorities of any country or territory through which a consignment of drugs is permitted to pass shall take all due measures to prevent the diversion of the consignment to a destination other than that named in the accompanying copy of the export authorization unless the Government of that country or territory through which the consignment is passing authorizes the diversion. The Government of the country or territory of transit shall treat any requested diversion as if the diversion were an export from the country or territory of transit to the country or territory of new destination. If the diversion is authorized, the provisions of paragraph 7 (a) and (b) shall also apply between the country or territory of transit and the country or territory which originally exported the consignment.
13. No consignment of drugs while in transit, or whilst being stored in a bonded warehouse, may be subjected to any process which would change the nature of the drugs in question. The packing may not be altered without the permission of the competent authorities.
14. The provisions of paragraphs 11 to 13 relating to the passage of drugs through the territory of a Party do not apply where the consignment in question is transported by aircraft which does not land in the country or territory of transit. If the aircraft lands in any such country or territory, those provisions shah be applied so far as circumstances require.
15. The provisions of this article are without prejudice to the provisions of any international agreements which limit the control which may be exercised by any of the Parties over drugs in transit.
16. Nothing in this article other than paragraphs 1 (a) and 2 need apply in the case of preparations in Schedule III.
