Three of the five transportation modes carried more U.S.-NAFTA trade in September than in September 2012, as the value of overall U.S. trade with its North American Free Trade Agreement partners, Canada and Mexico, rose 5% from year to year, according to newly released data from the U.S. Department of Transportation.
Trucks, which carries three-fifths of U.S.-NAFTA trade and is the most heavily utilized mode for moving goods to and from both the U.S. and its NAFTA partners, rose 5.4% while rail rose 8.1% Vessel declined 4.3% and air 0.1%. Pipelines showed the most year-to-year growth at 14.2%. The increase in the value of freight carried by pipelines reflects the rise in prices for oil and other petroleum products, the primary commodity transported by pipelines.

Trucks were followed by rail at 16.1%, vessels at 8.6%, pipeline at 7.2% and air at 3.9%. The surface transportation modes of truck, rail and pipeline carried 82.7% of the total NAFTA freight.
For trade with Canada in September, trucks carried 54.2% of the $53.1 billion of freight, followed by rail at 16.8%, pipelines at 12.3%, vessel at 5.85 and air at 4.5%. The surface transportation modes of truck, rail and pipeline carried 83.3% of the total U.S.-Canada freight flows.
For trade with Mexico in September, trucks carried 66% of the $41.3 billion of the freight, followed by rail at 15.1% vessel at 12.3%, air at 3.1% and pipelines at 0.7%. The surface transportation modes of truck, rail and pipeline carried 81.8% of the total U.S.-Mexico freight flows.
