1 The U.S. Department of Transportation, Bureau of Transportation Statistics estimated the weight of exports for truck, rail, pipeline, and other modes using weight-to-value ratios derived from imported commodities.

NOTES: Numbers may not add to totals due to rounding. 1 short ton = 2,000 pounds. "Other" includes shipments transported by mail, other and unknown modes, and shipments through Foreign Trade Zones. Totals for the most recent year differ slightly from the Freight Analysis Framework (FAF) due to variations in coverage and FAF conversion of values to constant dollars. The weight of U.S. exports by land modes of transportation is not available because this data is not required to be reported on the paper Shipper's Export Declarations (SEDs) documents that are required by the U.S. Census Bureau. BTS uses value to weight ratio of U.S. imports at two-digit commodity code to calculate the export weights where available.
