U.S.-NAFTA freight totaled $99.8 billion as all five major transportation modes carried more freight by value with North American Free Trade Agreement (NAFTA) partners Canada and Mexico in June 2017 compared to June 2016, according to the TransBorder Freight Data released today by the U.S. Department of Transportation’s Bureau of Transportation Statistics (BTS) (Figure 2, Table 1).

The 7.7 percent rise from June 2016 is the eighth consecutive month in which the year-over-year value in current dollars of U.S.-NAFTA freight increased from the same month of the previous year (Figure 1).

Freight by Mode

The value of commodities moving by pipeline increased 26.3 percent, vessel by 14.5 percent, rail by 9.8 percent, truck by 4.4 percent, and air by 1.9 percent (Figure 2, Table 2).

Trucks carried 63.4 percent of U.S.-NAFTA freight and continued to be the most heavily utilized mode for moving goods to and from both U.S.-NAFTA partners. Trucks accounted for $32.2 billion of the $53.2 billion of imports (60.6 percent) and $31.0 billion of the $46.6 billion of exports (66.6 percent) (Table 2).

Rail remained the second largest mode by value, moving 15.5 percent of all U.S.-NAFTA freight, followed by vessel, 6.4 percent; pipeline, 5.3 percent; and air, 3.8 percent. The surface transportation modes of truck, rail and pipeline carried 84.1 percent of the total value of U.S.-NAFTA freight flows (Table 2).

From June 2016 to June 2017, the value of U.S.-Canada freight flows increased by 6.0 percent to $51.1 billion as the value of freight on three major modes increased from a year earlier. The value of freight carried on pipeline increased by 30.5 percent, rail by 8.1 percent, and truck by 2.3 percent. Air decreased by 2.9 percent and vessel decreased by 10.3 percent (Figure 3, Table 3).

Trucks carried 58.3 percent of the value of the freight to and from Canada. Rail carried 16.1 percent followed by pipeline, 9.8 percent; air, 4.5 percent; and vessel, 3.4 percent. The surface transportation modes of truck, rail and pipeline carried 84.1 percent of the value of total U.S.-Canada freight flows (Table 3).

The top commodity category transported between the U.S. and Mexico in June 2017 was also vehicles and parts, of which $4.1 billion or 45.4 percent moved by truck and $4.0 billion or 43.7 percent moved by rail (Figure 6).
