USMCA — qualifying goods may enter duty-free

The United States imports substantial quantities of ores, slag, ash from Canada, with approximately $783B in total bilateral trade.

As of mid-2026, ores, slag, ash imports from Canada face a base tariff rate of 10% under the Section 301 forced-labor tariff (a two-tier 10%/12.5% duty), which replaced the flat 10% Section 122 rate when it expired July 24, 2026. Section 122 had itself replaced the IEEPA reciprocal tariff following the Supreme Court's 6-3 ruling in Learning Resources v. Trump (with V.O.S. Selections) on February 20, 2026.

Under the Trade Act of 1974, Section 122 tariffs are limited to 150 days, so the flat 10% Section 122 rate expired on July 24, 2026. It was replaced the same day by USTR's Section 301 forced-labor tariff, and Canada's current 10% base surcharge is that two-tier (10%/12.5%) rate.

Ores, Slag, Ash (HTS Chapter 26) 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 Canada.

Canada is party to the USMCA, which may provide preferential or duty-free access for qualifying ores, slag, ash. Importers should verify rules of origin requirements to take advantage of preferential rates.

Key products in HTS Chapter 26 imported from Canada include Iron ore, Copper ore, Bauxite (aluminum ore), Lead ore, Zinc ore, and Manganese ore.
