Article 3 is replaced by the following: Article 3 1. Before issuing the authorization, the customs authority shall check that the conditions for use of the arrangements, in particular the economic conditions, are fulfilled. 2. For the purposes of Article 5 (1) (c) of the basic Regulation, the customs authorities shall ensure that it is possible to establish that the compensating products have been made from temporarily exported goods, by means, in particular, of the following : (a) the statement or description of special marks or manufacturer’s numbers ; () OJ No L 212, 2. 8. 1986, p. 1. () OJ No L 230, 17. 8. 1987, p. 1. () OJ No L 391, 31. 12. 1987, p. 1. (b) the affixing of plombs, seals, clip-marks or other distinctive marks ; (c) the taking of samples, illustrations or technical descriptions ; (d) the carrying-out of analyses ; (¢) the examination of supporting documents relating to the transaction under consideration (such  as contracts, correspondence, invoices) which leave no room for doubt that the compensating products are manufactured from the temporarily exported goods. The customs authority may also use the ‘information document to facilitate the temporary exportation of goods sent from one country for manufacture, proces- sing or repair in another’ provided for by the Customs Cooperation Council recommendation of 3 December 1963 and contained in Annex IL 3. Where the arrangements are used for the repair of goods, including restoring them to their original condition and putting them in order, whether or not in combination with the standard exchange system, the customs authority shall establish that the tempora- rily exported goods are capable of being repaired. If the customs authority considers that this condition is not fulfilled, it shall refuse authorization. 4. Where the standard exchange system is used, the customs authority shall, inter alia, make use of the verification methods listed in paragraph 2 (a), (c), (d) or {e). In the case of paragraph 2 (e), supporting docu- ments shall clearly demonstrate that the repair in question will be carried out by supplying a replace- ment complying with the conditions set out in Article 17 (1) of the basic Regulation. 5. For the application of paragraph 4, the customs authority shall, in particular, ensure that the benefit to be obtained by using the arrangements for substitution provided for in Article 16 (1) of the basic Regulation shall not be accorded for the improvement of the tech- nical performance of the goods. The customs authorities shall therefore check: — the contracts and other supporting documents rela- ting to the repair, and — the sales or leasing contracts and/or invoices rela- ting to the temporarily exported goods or the goods incorporating temporarily exported goods and, in particular, the terms set out therein. 6.  All copies of the papers examined in accordance with paragraphs 1 to 5 shall be kept for at least three calendar years from the end of the year in which the authorization was issued.
