Article 501. Certificate of Origin
1. The Parties shall establish by January 1, 1994 a Certificate of Origin for the purpose of certifying that a good being exported from the territory of a Party into the territory of another Party qualifies as an originating good, and may thereafter revise the Certificate by agreement.
2. Each Party may require that a Certificate of Origin for a good imported into its territory be completed in a language required under its law.
3. Each Party shall:
Require an exporter in its territory to complete and sign a Certificate of Origin for any exportation of a good for which an importer may claim preferential tariff treatment on importation of the good into the territory of another Party; and
Provide that where an exporter in its territory is not the producer of the good, the exporter may complete and sign a Certificate on the basis of
Its knowledge of whether the good qualifies as an originating good,
Its reasonable reliance on the producer's written representation that the good qualifies as an originating good, or
A completed and signed Certificate for the good voluntarily provided to the exporter by the producer. 4. Nothing in paragraph 3 shall be construed to require a producer to provide a Certificate of Origin to an exporter.
5. Each Party shall provide that a Certificate of Origin that has been completed and signed by an exporter or a producer in the territory of another Party that is applicable to:
A single importation of a good into the Party's territory, or
Multiple importations of identical goods into the Party's territory that occur within a specified period, not exceeding 12 months, set out therein by the exporter or producer, Shall be accepted by its customs administration for four years after the date on which the Certificate was signed.
