The amount of freight flowing between the U.S. and its NAFTA partners, Canada and Mexico, increased 8.5% in July from the same time a year ago.
New U.S. Transportation Department figures show it totaled $101.1 billion, with increases in all five major transportation modes: air, vessel, pipeline, rail, and trucks. This is the fifth consecutive month with U.S.-NAFTA freight flows exceeding $100 billion.
Of the $7.9 billion increase in the value of US-NAFTA freight from July 2013, truck freight contributed the most, $4.7 billion, followed by rail, $1.4 billion. The trucking increase was due to growth in truck freight with both Mexico, up $2.5 billion, and Canada, up $2.2 billion.
Trucks carry three-fifths of U.S.-NAFTA freight and are the most heavily utilized mode for moving goods to and from both U.S.-NAFTA partners. Trucks carried 59.2% of U.S.-NAFTA freight in July 2014, accounting for $30.5 billion of exports and $29.3 billion of imports.
In July, the value of commodities moving by pipeline grew by the largest percentage of any mode, 10.8%. Rail freight increased 10% followed by a truck increase of 8.5%, vessel increase of 5.6%, and an air increase of 1.2%.
Year-to-year, the percent change in the value of U.S.-Canada freight moved by vessel increased the most of any mode, growing 30.9%, followed by a pipeline increase of 10.7%. Freight moved by rail increased by 8.5%, truck by 8%, and air by 2%.
Trucks carried 52.7% of the $55.2 billion of freight to and from Canada, followed by rail at 15.2%, pipeline at 14.8%, vessel at 6.3% and air at 4%. The surface transportation modes of truck, rail and pipeline carried 82.8% of the total U.S.-Canada freight flows.
In July 2014, the top commodity category transported between the U.S. and Canada was mineral fuels, of which $8.1 billion, or 60.2%, moved by pipeline.
Year-to-year, the value of rail freight rose 12% in July, the largest percentage increase of any U.S.-Mexico mode. Freight moved by pipeline increased 11.4% and truck by 8.8%, while air and vessel decreased by 0.1% and 5.3%, respectively.
Trucks carried 66.9% of the $45.9 billion of freight to and from Mexico, followed by rail at 14.2%, vessel at 12.6%, air at 2.7% and pipeline at 0.9%.
