One 20-foot container equals 1 TEU while one 40-foot container equals 2 TEUs. The data in this table include only loaded containers engaged in U.S. international maritime activity, including U.S. imports, exports, and transshipments. Transshipments are shipments neither originating nor are destined for the United States but passing through it from one foreign country to another. For example, an automobile component shipped from Japan and destined for Mexico, may pass through the Ports of Los Angeles and Long Beach before being trucked to Mexico. Therefore the trade levels will be greater than those reported in U.S. international trade statistics, which exclude transshipments. The data also exclude military shipments. Pacific Coast incldues ports in Alaska and Hawaii. One metric ton equals 1.1 short tons.",,,,,,,, "SOURCE: U.S. Department of Transportation, Maritime Administration, may 2002; based on Journal of Commerce, Port Import/Export Reporting Service (PIERS), 2001 PIERS data.",,,,,,,, ,,,,,,,,
