Preferential origin compliance: denial of preferential tariff treatment may apply until manufacturing changes are demonstrated and verified. If an investigation finds that goods in an origin certificate fail the origin criterion, duties shall be levied as for third country imports and sanctions under the Agreement and applicable domestic law apply; the importing authority may deny preferential tariff treatment for identical future imports from the same producer until it is clearly shown that manufacturing conditions were modified to meet the Rules of Origin, and disagreement over such demonstration may be referred to the Agreement's Dispute Settlement Procedure.
