In 2018, the overall export value of US-NAFTA air freight flows stood at around 17.5 billion U.S. dollars while import values amounted to 12.3 billion U.S. dollars. The main commodities transported by air between the U.S. and Canada were electrical machinery equipment and parts, computer-related machinery and parts, as well as aircraft, spacecraft and parts. They accounted for a combined total of over 50 percent of the value of commodities traded between both nations in 2018. In that same year, the total commodities imported into the U.S from Canada amounted to over 12.28 billion U.S. dollars.
Between the U.S. and Mexico, the leading commodities transported by air between both nations were electrical machinery equipment and parts, computer-related machinery and parts, as well as pearl, stones, metals and imitation jewelry. These commodities accounted for a combined total of 64 percent of the air trade value between the U.S. and Mexico in that year. The total value of commodities exported to Mexico from the U.S. in 2018 stood at approximately 9.8 billion U.S. dollars.
A large drop in the price of crude oil and petroleum price in 2016 caused a 3.3 percent decline—in comparison to the previous year—in the total value of U.S. freight trade with NAFTA partners also affecting the value of commodities moved by air between the U.S. and the other NAFTA members in that year.
