CBP and the Treasury Department have carefully reviewed the comments submitted in response to the rules of origin proposal. In particular, the agencies have heard concerns expressed about the impact that an extension of the rules of origin to non-NAFTA countries may have on the trade community. These matters are still under consideration within the agencies as part of the official rule-making process; however, CBP expects to soon be publishing a notice on this matter in the Federal Register. (In July 2008, CBP issued a proposed rule to use uniform tariff shift and other rules for CBP determinations of the country of origin of imported merchandise, etc. CBP subsequently extended the comment period and reopened the comment period on the proposed rule.)
