What Is the Section 301 Tariff Replacement — And How Much Is It?

Short answer: As Section 122's 10% tariff expires July 24, 2026, the USTR's Section 301 action is stepping in with proposed duties of 10–12.5% — and unlike Section 122, it has no statutory expiration date, renewing on four-year cycles (industrialsage, 7/16; AP, 7/16). Your specific rate depends on your HTS code and country of origin.

Why Section 301 is different from Section 122

Section 122 was a temporary balance-of-payments measure with a hard 150-day clock. Section 301 is a trade-enforcement authority tied to findings against specific practices and countries — it does not sunset automatically, and past Section 301 actions have persisted for years. That single difference — no expiry — is why “the tariff wall is being rebuilt” rather than dismantled (AP, 7/16). Hearings on the replacement were held in early July.

How to find your rate

There is no single flat number. Your post-cliff duty is a stack:

• Section 301 replacement (10–12.5%, proposed) —
• + Section 232 where steel/aluminum/derivatives apply —
• + any ADD/CVD order on your product/country —
• + MFN base duty and reciprocal measures.

The only reliable answer is a per-HTS-code calculation against the current Federal Register notice.
