Section 232 steel tariff applies at 25%

A 25% Section 232 tariff applies to covered steel imports from all origins, stacking on top of the base MFN duty and any other measures in force.

Effective 12 March 2025, a 25% Section 232 tariff applies to covered steel imports — for example flat-rolled iron and non-alloy steel under HTS heading 7208 — from all origins.

How it stacks

Section 232 is additive: it sits on top of the base MFN rate and applies regardless of country of origin (unlike Section 301, which is China-specific). For a covered steel code, the duty you owe is the MFN rate plus 25%, plus any IEEPA or reciprocal measures in force, plus the MPF and HMF fees.

What to do

Confirm whether your code is covered and see the full stack with the [tariff calculator](/tariff-calculator) — enter the HTS code and origin to read each layer with its effective date. To understand how the layers combine, read [tariff stacking explained](/blog/tariff-stacking-explained).
