US Tariffs on Ores, Slag, Ash from Indonesia — 10% (2026)

Indonesia is a significant source of ores, slag, ash imports into the United States, with approximately $38B in total bilateral trade.

As of March 2026, ores, slag, ash imports from Indonesia 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.

Ores, Slag, Ash (HTS Chapter 26) generally enter duty-free at the MFN level, with the Section 122 tariff as the primary duty. No additional Section 232 or Section 301 surcharges apply to most products in this category from Indonesia.

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