Preferential origin denial: identical goods claims can be rejected after prior origin non compliance unless origin is later demonstrated. When goods from an exporter or producer are determined not to meet the origin criteria, the Commissioner may, without further verification, reject other claims for the preferential rate of duty on identical goods from the same exporter or producer. The Commissioner must give written reasons for such rejections and shall restore preferential tariff treatment prospectively once documentation shows the exporter or producer has modified manufacturing or origin related conditions to fulfil the Rules of Origin.
