🇲🇽 Mexico vs 🇨🇳 China Tariffs — Import Duty Comparison (2026)

Mexico and China are both significant US trading partners, but their tariff profiles differ in important ways that affect import costs.

Mexico has a lower effective tariff rate (10%) compared to China (37.5%), a difference of 27.5%.

Both countries export Auto parts to the United States, creating direct competition in these sectors.

In terms of trade volume, Mexico accounts for approximately $779B in bilateral trade with the US, exceeding China's $575B.

Both countries are subject to the Section 301 forced-labor tariff that replaced the flat 10% Section 122 rate on July 24, 2026 — a two-tier 10%/12.5% duty on roughly 60 economies (about 99.4% of US imports by value), broader than the earlier 46-country proposal. Section 122 had itself replaced the IEEPA tariffs struck down by the Supreme Court. In August 2026, 25 states sued to block the forced-labor tariff, but CBP continues collecting it while the case proceeds.

Mexico's advantages include: Lower overall tariff rate (10% vs 37.5%); Trade agreement: USMCA (duty-free on qualifying goods); Not subject to Section 301 tariffs (China-specific); Higher US trade volume ($779B vs $575B); Unique export categories: Motor vehicles, Computers, Electrical machinery. China's advantages include: Unique export categories: Electronics, Machinery, Furniture.

For most product categories, Mexico currently offers lower import costs due to its tariff advantage. However, importers should consider factors beyond tariffs including shipping costs, lead times, quality standards, and supply chain reliability.
