In May 2018, the overall export value of US-NAFTA air freight flows stood at around 2.2 billion U.S. dollars while import values amounted to 1.7 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 measuring and testing instruments. They accounted for a combined total of more than 50 percent of the value of commodities traded between both nations in 2017. In that same year, the total commodities imported into the U.S from Canada amounted to over 11.3 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, pearl, stones, metals and imitation jewelry, as well as computer-related machinery and parts. These commodities accounted for a combined total of 63 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 2017 stood at approximately 9.2 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.
