Trucks are the primary mode of transportation for imports to the United States from Mexico and Canada when considering imports by value. Imports from Mexico increased nearly 50% from 2004 to 2016 totaling $294 billion adjusted for inflation. Of that value, 72% was transported by truck in 2016. Imports from Canada decreased by about 15% during that same period with a total value of $278 billion in 2016. Although trucks carry a lower percentage of import value from Canada than Mexico, the truck mode is still the largest single mode of transport from Canada accounting for 54% in 2016. A notable difference between Canada and Mexico is that pipeline accounts for a significant portion of import value from Canada while almost none from Mexico.
