U.S.–China Trade War Tariffs
Starting in 2018, Washington imposed successive rounds of Section 301 tariffs of 7.5–25%—and later higher blanket rates—on hundreds of billions of dollars in Chinese imports, citing unfair trade practices and security concerns. China retaliated with its own tariffs and other measures, and most duties have survived changes in U.S. administrations.
Supply chains shifted, costs rose for many manufacturers, and both sides took an economic hit while negotiating temporary truces.
Tariffs normalized a more fragmented, politicized trade system and paved the way for copycat moves by other countries in strategic sectors.
Mexico’s tariff wall mirrors the U.S. playbook—using across‑the‑board duties to manage China’s rise and signal industrial policy priorities, knowing that unwinding them later is politically difficult.
