Voluntary OPEC production cuts have been contributing to reduced U.S. crude oil imports from OPEC so far in 2021. Comparatively stable U.S. crude oil imports from Canada, however, have been mostly the result of longer-term trends. Between 2005 and 2020, U.S. crude oil imports from OPEC members decreased rapidly, but imports from non-OPEC members remained relatively high. In particular, U.S. crude oil imports from Canada more than doubled to average 3.6 million b/d in 2020, which was more than the combined total of crude oil imports from all other countries.
