Artikel 3

1. Each Contracting Party shall apply the provisions of article 2, paragraph 1, of the present Convention, without requiring in respect of importation or exportation either the production of a Customs document or security in respect of import duties and import taxes, to pallets pooled under an agreement by which the parties thereto:
(a) exchange among themselves, from country to country, pallets of one and the same type in the course of operations involving the international transport of goods,
(b) keep accounts, for each type of pallet, showing the number of pallets so exchanged from country to country, and
(c) undertake to deliver to one another within a specified period the number of pallets of each type necessary to offset at regular intervals, on a bilateral or multilateral basis, the outstanding balances of the accounts so kept.
2. The provisions of paragraph 1 of this article shall be applicable only if:
(a) pallets bear a marking conforming to that laid down in the pooling agreement;
(b) the pooling agreement has been communicated to the Customs administrations of the Contracting Parties concerned and these administrations have approved it, being satisfied that the types of pallet are sufficiently well defined and that the due and proper implementation of the agreement is adequately ensured.
