Miscellaneous Chemical Products from United Kingdom Tariff: 10% (2026)

Miscellaneous Chemical Products from United Kingdom represent an important segment of bilateral trade, with approximately $138B in total bilateral trade.

The current tariff framework for miscellaneous chemical products from United Kingdom reflects the post-SCOTUS landscape: a 10% base tariff under the Section 301 forced-labor tariff that replaced the flat 10% Section 122 rate on July 24, 2026, which had itself replaced the previously higher IEEPA rates after the Court's February 2026 ruling.

The flat 10% Section 122 tariff was subject to a 150-day statutory time limit and expired on July 24, 2026. It was replaced the same day by USTR's Section 301 forced-labor tariff — a two-tier 10%/12.5% duty on roughly 60 economies (about 99.4% of US imports by value), broader than the earlier 46-country proposal. United Kingdom's current 10% base surcharge is that forced-labor rate; in August 2026, 25 states sued at the Court of International Trade to block it, but CBP continues collecting it while the case proceeds.

Miscellaneous Chemical Products (HTS Chapter 38) carry an average MFN duty rate of 4% in addition to the base forced-labor tariff. No additional Section 232 or Section 301 surcharges apply to most products in this category from United Kingdom.

Key products in HTS Chapter 38 imported from United Kingdom include Insecticides, Herbicides, Fungicides, Anti-freeze preparations, Activated carbon, and Solvents.
