US-NAFTA freight falls 7.2 percent in 2015
All five major transportation modes – truck, rail, pipeline, vessel and air – carried less US freight with North American Free Trade Agreement (NAFTA) partners Canada and Mexico by value in 2015 than in 2014. The total value of cross-border freight carried on all modes fell 7.2 percent from 2014 to $1.1 trillion in current dollars, according to the US Department of Transportation’s Bureau of Transportation Statistics (BTS).
The value of commodities moving by truck declined 0.4 percent, the smallest decrease from 2014 to 2015 of any mode, 0.4 percent. The value of freight on other modes also declined: air 1.8 percent; rail 7.1 percent; vessel 29.7 percent; and pipeline 39.4 percent. A drop in the price of crude oil in 2015 played a key role in the large declines in the dollar value of goods shipped by vessel and pipeline. Average monthly prices for crude petroleum and refined fuel are available from the US Energy Information Administration.
The 7.2 percent decline in the value cross-border freight from 2014 to 2015 was almost entirely due to the decline in crude oil and petroleum prices. The value of petroleum-related commodity shipments declined almost 40 percent year-over-year while the value of other freight dropped 0.9 percent. In 2015, petroleum-related commodities comprised 10.8 percent of the total value of US North American freight, down from 16.6 percent in 2014. Some data used to calculate the percentages in this paragraph comes from US International Trade Commission Interactive Tariff and Trade Data, which allows the separation of petroleum and non-petroleum components of mineral fuels.
Trucks carried 64.3 percent of US-NAFTA freight, a 2.2 percentage point increase from 2005, and continued to be the most heavily utilized mode for moving goods to and from both US-NAFTA partners. Trucks accounted for $359.8 billion of the $589.9 billion of imports (61.0 percent) and for $351.9 billion of the $516.4 billion of exports (68.2 percent).
Rail remained the second largest mode, moving 14.9 percent of all US-NAFTA freight, followed by vessel, 6.6 percent; pipeline, 5.2 percent and air, 3.9 percent. The surface transportation modes of truck, rail and pipeline carried 84.4 percent of the total value of US-NAFTA freight flows.
