Tariff Calculator: U.K. → U.S. (2026)
U.K.-to-U.S. duty in 2026 = the MFN base rate (by 8-digit HTS code) + the global 301 U.K. tier of 10% (since 2026-07-24, FR 2026-15181); where a Section 232 sector is hit (steel/aluminium/copper 50%, autos 25%, etc.) the sector rate displaces the 301 layer. Sea freight adds HMF 0.125%; formal entries add MPF ($34.58–$670.86 per entry, FY2027). The calculator below ships prefilled with the U.K. as origin — enter your HTS code and value for the full stack.
What changed on this lane in 2026: the IEEPA tariffs ended and moved into refund processing, the global 301 U.K. tier of 10% took effect, and the pharma 232 general tier went live. Your entry cost is decided by the layers below — there is no preferential U.S.–U.K. rate layer in force.

What changed on this lane in 2026
- 2026-02-24IEEPA fentanyl tariff struck down (a 10% duty on all origins from 2025-02-04) — duties paid in the window are refundable via CBP CAPE
- 2026-07-24Global 301 effective: the U.K. at a flat 10% tier (FR 2026-15181), stacked on the same value as MFN; Section 232-covered and Annex I/II-exempt goods skip this layer
- 2026-09-29Pharma Section 232 general tier of 20% takes effect — U.K. pharmaceuticals hit by 232 pay the sector rate, displacing the global 301 layer
Also: the global 301 program remains in litigation at the Court of International Trade (schedule set); CBP enforcement prevails. Section 232 sector rates are origin-agnostic and displace the global 301 layer when hit: steel/aluminium/copper 50%, autos & parts 25%, furniture 25%, semiconductors 25%, pharma general tier 20%, softwood timber 10%.

Do U.K. goods get caught by the Section 232 sector tariffs?
Section 232 is origin-agnostic: steel/aluminium/copper 50%, autos & parts 25%, furniture 25%, semiconductors 25%, pharma general tier 20% (since 2026-09-29), softwood timber 10%. Whether a code is hit depends on the 8-digit HTS falling in each sector's scope — the calculator shows it layer by layer with source links.
Can I get a refund of the IEEPA tariff I paid?
Yes. The IEEPA fentanyl tariff ran at 10% on all origins (the U.K. included) from 2025-02-04 to 2026-02-24, when the Supreme Court struck it down; duties paid in the window are claimable through CBP's CAPE process (file as the importer of record, or route through your carrier/broker).
