The main import partners of US states: Canada ranks first in 23 states, and Taiwan ranks first in 5 states.

There are 50 states in the United States, and the import sources of each state are different. In addition to being affected by geographical location, it is also related to industrial structure and infrastructure. According to the 2025 data compiled by the U.S. Census Bureau, the largest import partners of U.S. states are quite dispersed. Canada has a clear advantage, becoming the largest source of imports in 23 states, and Taiwan ranks first in 5 states.

Data shows that Canada is the largest import partner for most U.S. states, including Montana, Maine, Vermont and Washington, which border Canada. However, Canada’s influence is not limited to the northern border states. Even southern regions such as Oklahoma and Colorado also list Canada as the largest source of imports.

Mexico ranks second, with a total of 9 states considering it as the largest import partner. It is worth noting that there is a special situation in Delaware, with Canada and Mexico tied for first place. The state will import US$988 million in goods from the two countries in 2025.

Asian countries also play an important role, with Taiwan becoming the largest import partner of five states and China ranking first in four states. Australia, Switzerland, Japan and Costa Rica each became the largest source of imports for one state.

Taiwan is the largest import partner of five states. Nevada has 45.2% of its goods coming from Taiwan; Arizona has 29.1%; New Mexico has 34.2%; Utah has 20.8%; and Kentucky has 11.4%.

The degree of dependence of some states on imports from a single country is even more alarming. With 91.4% of its imported goods coming from Canada, Montana is the most dependent state on its largest import partner in the United States. This also means that once tariffs, trade disputes or changes in commodity prices and supplies occur, the local economy may be significantly affected.

In comparison, New Jersey is the least dependent on a single source of imports. Although India is the state's largest import partner, its import volume in 2025 will be approximately US$11.5 billion, accounting for only 7.8% of New Jersey's total import volume of US$147.8 billion, indicating that its import sources are relatively dispersed.

In addition, the largest import partners of some states are also unexpected. For example, Indiana's largest import source is Ireland, Nebraska is Thailand, and Idaho is Malaysia.

Overall, the import landscape of U.S. states in 2025 shows obvious differences. Canada has become the largest import partner of 23 states due to its geographical advantages, followed by Mexico. Taiwan also occupies the largest import source position in 5 states, reflecting the highly diverse and close connections between various parts of the United States and the global supply chain.
