Special Import Provisions (US-specific) from Mexico Tariff: 10% (2026)

Special Import Provisions (US-specific) from Mexico represent an important segment of bilateral trade, with approximately $779B in total bilateral trade.

Following the Supreme Court's landmark February 20, 2026 decision striking down IEEPA tariffs, imports of special import provisions (us-specific) from Mexico are now subject to a 10% base tariff under the Section 301 forced-labor tariff, which replaced the flat 10% Section 122 rate (in effect February 24 – July 24, 2026).

This 10% base surcharge is the Section 301 forced-labor tariff that replaced the flat 10% Section 122 rate when Section 122's 150-day authority expired on July 24, 2026. The final action covers roughly 60 economies under a two-tier 10%/12.5% structure — broader than the earlier 46-country proposal.

Special Import Provisions (US-specific) (HTS Chapter 99) generally enter duty-free at the MFN level, with the base forced-labor tariff as the primary duty. No additional Section 232 or Section 301 surcharges apply to most products in this category from Mexico.

Mexico is party to the USMCA, which may provide preferential or duty-free access for qualifying special import provisions (us-specific). Importers should verify rules of origin requirements to take advantage of preferential rates.

Key products in HTS Chapter 99 imported from Mexico include Section 232 steel/aluminum tariff items, Section 301 China tariff items, Section 201 safeguard items, Anti-dumping duty items, Countervailing duty items, and related items.
