164.We understand that the United States also applies a uniform standard throughout its territory, regardless of the particular conditions existing in certain parts of the country. The United States requires the use of approved TEDs at all times by domestic, commercial shrimp trawl vessels operating in waters where there is any likelihood that they may interact with sea turtles, regardless of the actual incidence of sea turtles in those waters, the species of those sea turtles, or other differences or disparities that may exist in different parts of the United States. It may be quite acceptable for a government, in adopting and implementing a domestic policy, to adopt a single standard applicable to all its citizens throughout that country. However, it is not acceptable, in international trade relations, for one WTO Member to use an economic embargo to require other Members to adopt essentially the same comprehensive regulatory program, to achieve a certain policy goal, as that in force within that Member's territory, without taking into consideration different conditions which may occur in the territories of those other Members.
