US Tariffs on Silk from Mexico — 10% (2026)

The United States imports substantial quantities of silk from Mexico, with approximately $779B in total bilateral trade.

As of March 2026, silk imports from Mexico face a base tariff rate of 10% under Section 122 of the Trade Act of 1974. This rate replaced the previous IEEPA reciprocal tariff following the Supreme Court's 6-3 ruling in V.O.S. Selections Inc. v. United States on February 20, 2026.

Under the Trade Act of 1974, Section 122 tariffs are limited to 150 days. The current 10% rate expires around July 24, 2026. Congressional action would be required to extend these tariffs beyond that date.

Silk (HTS Chapter 50) carry an average MFN duty rate of 2.5% in addition to the Section 122 tariff. 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 silk. Importers should verify rules of origin requirements to take advantage of preferential rates.

Key products in HTS Chapter 50 imported from Mexico include Raw silk, Silk yarn, Silk woven fabrics, Silk waste, Noil silk, and Silk scarves (fabric).
