US Tariffs on Inorganic Chemicals from Ireland — 10% (2026)

Importers sourcing inorganic chemicals from Ireland face specific tariff considerations, with approximately $115B in total bilateral trade.

As of March 2026, inorganic chemicals imports from Ireland 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.

Inorganic Chemicals (HTS Chapter 28) carry an average MFN duty rate of 3.2% in addition to the Section 122 tariff. No additional Section 232 or Section 301 surcharges apply to most products in this category from Ireland.

Key products in HTS Chapter 28 imported from Ireland include Hydrochloric acid, Sulfuric acid, Sodium hydroxide, Hydrogen peroxide, Titanium dioxide, and Rare-earth compounds.
