a BTS estimated those weights for truck, rail, pipeline, and other and unknown based on value-to-weight ratios from the import data because export weights for surface modes are not currently reported. Weight for water and air exports and imports are from the U.S. Department of Commerce, U.S. Census Bureau.
Notes: Value based on millions of U.S. dollars; weight based on millions of short tons.
