Figure 1. Rules of Origin Uses
Non-preferential ROO apply to imports from all countries
with which the importing country has normal trade relations
(NTR), and are consistent with World Trade Organization
(WTO) obligations. For the United States, NTR applies to
all WTO members, except those that have an FTA with the
United States or receive another kind of U.S. preferential
trade treatment. Non-preferential ROO are used to assess
tariffs, enforce trade laws (e.g., antidumping and
countervailing duties), collect statistics, and for other
purposes.
For non-preferential ROO, there is no specific U.S. law or

Textiles and Apparel
Most bilateral and regional FTAs negotiated by the United
States over the past two decades, beginning with the North
America Free Trade Agreement (NAFTA), have included
the “yarn forward rule” for most textile and apparel
products. This requires that in order to receive the tariff-free

country, all subsequent manufacture, including spinning
