What is the total tariff rate after Section 122 expires?

There is no single rate. After Section 122 expires July 24, 2026, your cost is a stack: the Section 301 replacement (10-12.5%) plus any Section 232, ADD/CVD, MFN base duty, and reciprocal measures for your specific HTS code and country of origin.

Why is my effective tariff higher than the headline rate?

Headline rates usually quote a single layer. Section 232, ADD/CVD, and reciprocal measures stack on top, so the effective rate can be much higher than the number you first see.

How Much Will Tariffs Cost My Business After July 24, 2026?

Short answer: There's no single percentage — your post-cliff tariff cost is a stack of layers, and it's specific to each HTS code. After Section 122 expires July 24, 2026, the base shifts to the Section 301 replacement (10–12.5%, no expiry), and on top of that you may carry Section 232, ADD/CVD, MFN base duty, and reciprocal measures. Two products from the same supplier can land at very different effective rates.

The layers that make up your real cost

Section 301 replacement — 10–12.5% (proposed), the successor to Section 122.
Section 232 — steel/aluminum and derivative products.
ADD/CVD — antidumping/countervailing orders on specific products and countries.
MFN base duty — your HTS code's standard rate.
Reciprocal / country-specific — where applicable.
Fees — HMF (0.125%), MPF (0.3464%), broker, insurance.

Why the “headline rate” misleads

Most cost estimates quote one layer and miss the stack. A product that looks like “10%” can effectively be double once Section 232 and ADD/CVD are added. The only accurate figure comes from computing all layers against your exact HTS classification and country of origin.
