A new U.S. Transportation Department repot shows three of the five surface transportation modes, truck, rail and pipeline, carried more U.S. trade with North American Free Trade Agreement partners Canada and Mexico by value in 2013 than compared to the year before.

Trade by pipeline also grew the most from year-to-year, 7.7%, partly due to the value of petroleum products, as the overall value on all modes rose 2.6%. Smaller increases took place on rail, advancing 4.6%, and truck increasing 2.2%, while vessel trade fell for the second consecutive year, losing 2.4% and air trade declined for the third straight year, falling 1%.

Most U.S.-NAFTA trade in 2013, 82.4%, was carried on the surface modes of truck, rail and pipeline. Trucks carried 59.7%, followed by rail at 15.4%, air at 9.1%, pipeline at 7.3% and vessel at 3.8%

Although truck carried more than half of U.S.-NAFTA trade last year, its share of total trade has dropped by 4 percentage points from 2004, the first year of DOT data for all modes, while the decline was 0.2 percent points in 2013 compared to 2012. Vessel’s percentage share rose 2.6 points while pipeline rose 1.9 points.
