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

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
benefits of an FTA, although fibers may be produced in any
country, all subsequent manufacture, including spinning
into yarn; weaving or knitting; dyeing; printing; finishing;
cutting and sewing; or other assembly into a finished
garment or textile product must take place in one of the
FTA partners. Depending on the product, some apparel
must comply with a “fiber forward” rule (more restrictive)

or a “fabric forward” rule (more liberal).
