1. (a) If the customs value of the imported goods cannot be determined under the provisions of Articles 1 and 2, the customs value shall be the transaction value of similar goods sold for export to the same country of importation and exported at or about the same time as the goods being valued.

(b) In applying this Article, the transaction value of similar goods in a sale at the same commercial level and in substantially the same quantity as the goods being valued shall be used to determine the customs value. Where no such sale is found, the transaction value of similar goods sold at a different commercial level and/or in different quantities, adjusted to take account of differences attributable to commercial level and/or to quantity, shall be used, provided that such adjustments can be made on the basis of demonstrated evidence which clearly establishes the reasonableness and accuracy of the adjustment, whether the adjustment leads to an increase or a decrease in the value.

2. Where the costs and charges referred to in paragraph 2 of Article 8 are included in the transaction value, an adjustment shall be made to take account of significant differences in such costs and charges between the imported goods and the similar goods in question arising from differences in distances and modes of transport.

3. If, in applying this Article, more than one transaction value of similar goods is found, the lowest such value shall be used to determine the customs value of the imported goods.

Article 4

If the customs value of the imported goods cannot be determined under the provisions of Articles 1, 2 and 3, the customs value shall be determined under the provisions of Article 5 or, when the customs value cannot be determined under that Article, under the provisions of Article 6 except that, at the request of the importer, the order of application of Articles 5 and 6 shall be reversed.

Article 5

1. (a) If the imported goods or identical or similar imported goods are sold in the country of importation in the condition as imported, the customs value of the imported goods under the provisions of this Article shall be based on the unit price at which the imported goods or identical or similar imported goods are so sold in the greatest aggregate quantity, at or about the time of the importation of the goods being valued, to persons who are not related to the persons from whom they buy such goods, subject to deductions for the following:

(I) either the commissions usually paid or agreed to be paid or the additions usually made for profit and general expenses in connection with sales in such country of imported goods of the same class or kind;

(ii) the usual costs of transport and insurance and associated costs incurred within the country of importation;

(iii) where appropriate, the costs and charges referred to in paragraph 2 of Article 8; and

(iv) the customs duties and other national taxes payable in the country of importation by reason of the importation or sale of the goods.

(b) If neither the imported goods nor identical nor similar imported goods are sold at or about the time of importation of the goods being valued, the customs value shall, subject otherwise to the provisions of paragraph 1(a), be based on the unit price at which the imported goods or identical or similar imported goods are sold in the country of importation in the condition as imported at the earliest date after the importation of the goods being valued but before the expiration of 90 days after such importation.

2. If neither the imported goods nor identical nor similar imported goods are sold in the country of importation in the condition as imported, then, if the importer so requests, the customs value shall be based on the unit price at which the imported goods, after further processing, are sold in the greatest aggregate quantity to persons in the country of importation who are not related to the persons from whom they buy such goods, due allowance being made for the value added by such processing and the deductions provided for in paragraph 1(a).

Article 6

1. The customs value of imported goods under the provisions of this Article shall be based on a computed value. Computed value shall consist of the sum of:

(a) the cost or value of materials and fabrication or other processing employed in producing the imported goods;

(b) an amount for profit and general expenses equal to that usually reflected in sales of goods of the same class or kind as the goods being valued which are made by producers in the country of exportation for export to the country of importation;

? The cost or value of all other expenses necessary to reflect the valuation option chosen by the Member under paragraph 2 of Article 8.

2. No Member may require or compel any person not resident in its own territory to produce for examination, or to allow access to, any account or other record for the purposes of determining a computed value. However, information supplied by the producer of the goods for the purposes of determining the customs value under the provisions of this Article may be verified in another country by the authorities of the country of importation with the agreement of the producer and provided they give sufficient advance notice to the government of the country in question and the latter does not object to the investigation.

Article 7

1. If the customs value of the imported goods cannot be determined under the provisions of Articles 1 through 6, inclusive, the customs value shall be determined using reasonable means consistent with the principles and general provisions of this Agreement and of Article VII of GATT 1994 and on the basis of data available in the country of importation.

2. No customs value shall be determined under the provisions of this Article on the basis of:

(a) the selling price in the country of importation of goods produced in such country;

(b) a system which provides for the acceptance for customs purposes of the higher of two alternative values;

? The price of goods on the domestic market of the country of exportation;

(d) the cost of production other than computed values which have been determined for identical or similar goods in accordance with the provisions of Article 6;

(e) the price of the goods for export to a country other than the country of importation;

(f) minimum customs values; or

(g) arbitrary or fictitious values.
