Tariff Calculator: Japan → U.S. (2026)
Japan-to-U.S. duty in 2026 = the MFN base rate (by 8-digit HTS code) + the global 301 Japan tier of 12.5% (since 2026-07-24, MFN+301 combined cap of 12.5%: goods whose MFN already exceeds 12.5% take no add-on; those below are topped up to 12.5% combined); where a Section 232 sector is hit (autos 25%, steel/aluminium/copper 50%, 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 Japan 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 Japan tier took effect (combined cap 12.5%), and the pharma 232 general tier went live. Your entry cost is decided by the layers below — there is no preferential U.S.–Japan rate layer in force.
U.S. full regime: MFN + 301 + 232 + MPF/HMF
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: Japan at a 12.5% tier, applied as an MFN+301 combined cap of 12.5% (FR 2026-15181 §1(a)(ii)) — low-MFN goods are topped up to 12.5% combined; goods already above 12.5% MFN take no add-on
- 2026-09-29Pharma Section 232 general tier of 20% takes effect — Japanese 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% (the main 232 exposure for this lane), furniture 25%, semiconductors 25%, pharma general tier 20%, softwood timber 10%.
Frequently asked questions
What duties do I pay importing from Japan into the U.S. in 2026?
It stacks: the MFN base rate (by 8-digit HTS code) + the global 301 Japan tier (MFN+301 combined cap of 12.5%). How the cap works: laptop 8471.30 (MFN Free) = 0% + 12.5% = 12.5% combined; cotton T-shirt 6109.10 (MFN 16.5%) = 16.5% + 0% = 16.5% combined (already above the cap, no add-on). Section 232 sector goods pay the sector rate instead of the 301 layer; sea freight adds HMF 0.125%, formal entries add MPF 0.3464% (FY2027, min $34.58 / max $670.86 per entry).

Do Japanese cars and machinery get caught by the Section 232 tariffs?
Autos and parts hit the Section 232 autos layer at 25% (since 2025-11-01) and pay the sector rate instead of the global 301 tier — Japanese vehicles pay 25%, not the 12.5% tier. Other sectors depend on the 8-digit HTS code: steel/aluminium/copper 50%, furniture 25%, semiconductors 25%, pharma 20%, softwood timber 10%. The calculator flags the hit sector 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 (Japan 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).

What should be on the commercial invoice for Japan-to-U.S. shipments?
Beyond the standard ten fields, cover this lane's specifics: the 10-digit HTS code, country of origin (Japan), value currency and Incoterms. The $800 de minimis has been suspended since 2025-08-29, so parcels pay the same stack. Generate a compliant invoice online.
