The 2010 edition of this annual report from the U.S. Trade Representative states,
"This report discusses the largest export markets for the United States, including: 58 nations, the European Union, Taiwan, Hong Kong, and one regional body. Some countries were excluded from this report due primarily to the relatively small size of their markets or the absence of major trade complaints from representatives of U.S. goods and services sectors. However, the omission of particular countries and barriers does not imply that they are not of concern to the United States.
NTE sections report the most recent data on U.S. bilateral trade in goods and services and compare it to the preceding period. This information is reported to provide context for the reader. In nearly all cases, U.S. bilateral trade declined in 2009 compared to the preceding period, reflecting the important negative impact of the severe global recession on international trade (with world Gross Domestic Product and world trade down 2.3 percent and 11.9 percent, respectively). The merchandise trade data contained in the NTE report are based on total U.S. exports, free alongside (f.a.s.)2 value, and general U.S. imports, customs value, as reported by the Bureau of the Census, Department of Commerce."
