Mexico Becomes Top U.S. Import Source — First Time Since 2002
Mexico surpassed China as the number-one source of U.S. goods imports in 2023, a position it held and extended through 2024 with $505.9 billion in imports versus China's $438.9 billion. The shift — the first time Mexico held this position since 2002 — was driven by escalating U.S.-China tariffs, USMCA automotive rules-of-origin requirements, and nearshore supply chain restructuring. Six independent sources confirm the import-ranking reversal, though analysts caution that trade diversion from China rather than new factory investment accounts for much of Mexico's volume gain.
Findings
- Mexico imported $505.9 billion in goods to the U.S. in 2024, versus China's $438.9 billion — a gap that widened from the 2023 margin of $475.6B vs. $427.2B (Census Bureau)
- The last time Mexico held the top-source position was 2002; the 20-year gap reflects the scale of China's WTO-era manufacturing rise and the magnitude of its reversal under sustained U.S. tariff pressure
- U.S.-China tariffs averaging ~18% on Chinese goods are the structural driver; Mexico's advantage is partly tariff arbitrage as some Chinese manufacturers route goods through Mexican assembly operations
- Dallas Fed research cautions that FDI inflows into Mexico actually declined after 2022, suggesting much of Mexico's import gain reflects trade diversion rather than a new wave of nearshore factory construction
