International Trade: Rules of Origin

Determining the country of origin of a product is important for properly assessing tariffs, enforcing trade remedies (such as antidumping and countervailing duties) or quantitative restrictions (tariff quotas), and statistical purposes. Other commercial trade policies are also linked with origin determinations, such as country of origin labeling and government procurement regulations. 

Rules of origin (ROO) can be very simple, noncontroversial tools of international trade as long as all of the parts of a product are manufactured and assembled primarily in one country. However, when a finished product's component parts originate in many countries—as is often the case in today's global trading environment—determining origin can be a very complex, sometimes subjective, and time-consuming process. 

U.S. Customs and Border Protection (CBP) is the agency responsible for determining country of origin using various ROO schemes. Non-preferential rules of origin are used to determine the origin of goods imported from countries with which the United States has most-favored-nation (MFN) status. Preferential rules are used to determine the eligibility of imported goods from certain U.S. free trade agreement (FTA) partners and certain developing country beneficiaries to receive duty-free or reduced tariff benefits under bilateral or regional FTAs and trade preference programs. Preferential rules of origin are generally specific to each FTA, or preference, meaning that they vary from agreement to agreement and preference to preference. 

CBP has periodically proposed implementing a more uniform system of ROO as an alternative to the "substantial transformation" rule that currently in place. In July 25, 2008, CBP's latest proposal suggested that a system known as the North American Free Trade Agreement (NAFTA) rules system "has proven to be more objective and transparent and provide greater predictability in determining the country of origin of imported merchandise than the system of case-by-case adjudication they would replace." The NAFTA scheme that would be applied has already been used for several years to determine the origin of imports under the NAFTA, and for most textile and apparel imports (about 40 percent of U.S. imports). The CBP proposed to apply the NAFTA rules to all country of origin determinations made by CBP, unless otherwise specified (e.g., unless the import enters under a preferential ROO scheme already in place). Such changes in rules of origin requirements are often opposed by some importers due to costs involved in transitioning to new rules, or because they believe that certain imported products might be at a disadvantage under new ROO methodology. As of this writing, the proposal has not been implemented. 

This report deals with ROO in three parts. First, we describe in more detail the reasons that country of origin rules are important and briefly describe U.S. laws and methods that provide direction in making these determinations. Second, we discuss briefly some of the more controversial issues involving rules of origin, including the apparently subjective nature of some CBP origin determinations, and the effects of the global manufacturing process on ROO. Third, we conclude with some alternatives and options that Congress could consider that might assist in simplifying the process.
