This is a common point of confusion, so we're happy to clarify.
While the North American Free Trade Agreement (NAFTA)—now succeeded by the United States-Mexico-Canada Agreement (USMCA)—provides duty-free treatment for many qualifying goods traded between the U.S., Canada, and Mexico, eligibility depends on where the product was manufactured and whether it meets the agreement's rules of origin.
Many of the parts we sell for European vehicles are manufactured outside of North America. Because of that, they generally do not qualify for duty-free treatment under the agreement, even if they are shipped from the United States. As a result, import taxes, duties, and other applicable fees may still be assessed on most international orders.
