Transportation facilities that move international trade into and out of the United States reveal the importance of all modes and intermodal combinations to global connectivity.

Top 25 U.S.-international freight gateways by value of shipments

Transportation facilities that move international trade into and out of the United states reveal the importance of all modes and intermodal combinations to global connectivity.  The top 25 U.S.-international freight gateways, measured by value of shipments in 2017, consist of 10 water ports, 5 land-border crossings, and 10 air gateways.  The Port of Los Angeles was the leading U.S.-international freight gateway (water), moving $214.8 billion in cargo.  The top 25 gateways accounted for 64.9 percent of the $3.89 trillion (current dollars) in total U.S.-international freight trade.

Value of U.S.-international merchandise trade by coasts and border

Foreign trade has had a major impact on all U.S. borders and coasts. An increase in trade with China has resulted in a large share of trade moving through Pacific coast ports, and the newly expanded Panama Canal allows larger vessels to transit between the Atlantis and Pacific Oceans. Since 2003, the value of merchandise trade increased by 54 percent in inflation adjusted terms. Ports and airports on the Atlantic coast continued to account for the largest share in terms of trade value. In 2018, they accounted for 30.6 percent of the total $3.2 trillion in trade (2009 dollars).

U.S.-international freight trade by transportation mode

Water is the leading transportation mode for U.S.-international freight trade. Ships moved 41.9 percent of the value (nearly $1.8 trillion) and 70.9 percent of the weight (1.6 billion tons) in 2018. Air freight, which accounted for 0.3 percent by weight, was the second largest mover of goods by value (27.5 percent), accounting for $1.16 trillion. Truck moved 10.4 percent of total freight and 18.4 percent of total value.  Together, rail and pipeline accounted for about 6.0 percent of the total value and 17.3 percent of the total weight of U.S.-international freight trade.

Domestic transportation mode of exports and imports by tonnage and value

International trade has grown considerably, and the movement of these goods within the United States is placing pressure on the domestic transportation network and on all modes. Trucks are the most common mode used to move imports and exports between international gateways and inland locations. This trend is expected to continue with tonnage of U.S.-international trade forecast to grow at a rate of about 2.9 percent per year between 2018 and 2045.

Top trading partners of the U.S. in merchandise trade

For the first time, Mexico is the United States’ top trade partner, followed by Canada and China. Mexico’s share of trade with the United States grew by 80.5 percent, from $303 to $547 billion between 2000 and 2019, while China’s share more than doubled from 6.0 to 13.5 percent, and its total value of freight grew from $148 to $497 billion over the same period. Two notable changes in the ranking of U.S. trade partners include Vietnam’s jump from 68 to 13, and India’s climb from 25 to 9 between 2000 and 2019.

Trade with Canada and Mexico

Value and tonnage of U.S. freight trade with Canada and Mexico by transportation mode

The value of freight shipped to and from our North American neighbors, Canada and Mexico, has grown by 88.2 percent since 2000.  Trucks were the most heavily utilized mode, carrying 62.8 percent of the value and 26.7 percent of the tonnage traded with these countries in 2018.  Every mode carried more U.S. freight by value with Canada and Mexico in 2018 than in 2017.

Value of U.S. exports to and imports from Canada and Mexico by land transportation mode

Truck and rail transport most of the U.S. bidirectional freight with Canada and Mexico. Goods carried by truck were largely responsible for the 94.5 percent increase in the value of freight from Mexico between 2000 and 2019. While trade via pipeline with these two countries increased markedly, it comprised a relatively small share of total trade value.

Number of incoming trucks, trains, and loaded containers crossing the U.S-Mexico and U.S-Canada borders

A large number of trucks and trains carry goods from Mexico and Canada to the United States. In 2019, approximately 6.4 million trucks hauled nearly 4.8 million loaded containers into the United States from Mexico, representing a doubling in the number of loaded containers entering the United States from Mexico in 2000.  In contrast, the number of incoming trucks and loaded containers on trucks from Canada declined by 20.4 and 18.2 percent, respectively, while incoming loaded rail containers increased by 55.2 percent over the same period.
