China and Mexico shares of U.S. goods imports
This chart compares China’s and Mexico’s trailing-year shares of U.S. goods imports using matching customs-basis Census and BEA series distributed through FRED. The shares describe country-of-shipment trade composition, not the origin of every component embedded in imported products.
What does it show?
Mexico now supplies a much larger share of U.S. goods imports than China on a trailing-12-month customs basis.
Methodology
Trailing-12-month sums of monthly, not-seasonally-adjusted U.S. goods imports from China (IMPCH) and Mexico (IMPMX), each divided by the matching customs-basis world goods-import total (IMP0015). The Census Bureau and Bureau of Economic Analysis publish the underlying series; FRED distributes them. Country-of-shipment trade shares do not identify the origin of every embedded component.
