(f) the legal authority for the verification visit.
4. Where an exporter or a producer has not given its written consent to a proposed verification visit within 30 days of receipt of notification pursuant to paragraph 2, the notifying Party may deny preferential tariff treatment to the good that would have been the subject of the visit.
5. Each Party shall provide that, where its customs administration receives notification pursuant to paragraph 2, it may, within 15 days from the date of receipt of such notification, postpone the proposed verification visit for a period not exceeding 60 days from the date of such receipt, or for such longer period as the Parties may otherwise agree.
6. A Party shall not deny preferential tariff treatment to a good based solely on the postponement of a verification visit pursuant to paragraph 5.
7. Each Party shall permit an exporter or a producer whose good is the subject of a verification visit by another Party to designate two observers to be present during such visit, provided that:
(a) the observers do not participate in a manner other than as observers; and
(b) the failure of such exporter or producer to designate observers shall not result in the postponement of the visit.
8. Each Party shall, through its customs administration, conduct a verification of a regional value-content requirement in accordance with the Generally Accepted Accounting Principles applied in the territory of the Party from which the good was exported.
9. The Party conducting a verification shall provide the exporter or producer whose good is subject to the verification with a written determination of whether the good qualifies as an originating good, including findings of fact and the legal basis for the determination.
10. Where verifications by a Party indicate a pattern of conduct by an exporter or a producer of false or unsupported representations that a good imported into its territory qualifies as an originating good, such Party may withhold preferential tariff treatment to identical goods exported or produced by such person until that person establishes compliance with the provisions of Chapter Four (Rules of Origin).
