Section 232 (steel & aluminum) and Section 301 (China) tariffs stack on top of the regular duty rate — and they can dwarf it. Enter your customs value and switch on the tariffs that apply to estimate your total tariff exposure and effective rate.
Declared value of the goods (USD).
The normal HS-code duty rate before the special tariffs (0 if duty-free).
Rates as of November 6, 2026: Proclamation of April 2, 2026 as amended in June 2026 (White House; CBP guidance CSMS #68855869). Rates vary by product, origin and exceptions (for example, Russian aluminum carries a higher rate, and the 15% rate runs to December 31, 2027). Check your HTS line before you rely on a preset.
Section 301 applies only to China-origin goods on the affected lists.
Rates as of November 6, 2026, from USTR Section 301 tariff actions. Items from the 2024 four-year review (solar cells, semiconductors, batteries, critical minerals, medical products and others) carry rates from 25% to 100% that depend on the product and its date, so they have no preset. Rates vary by product, origin and exclusions; check your HTS line.
Estimate only. Covers the duty + 232/301 tariff layers; it does not add MPF/HMF or sales tax (use the Customs Duty Calculator for full landed cost). Tariff rates and product coverage change frequently — verify with CBP/USTR.

Section 232 tariffs are national-security duties on imported steel and aluminum (and a growing list of derivative products), applied regardless of origin from covered countries. Section 301 tariffs are trade-remedy duties on goods from China, organized into lists with different rates. Both are additional duties: they're added on top of the normal HS-code (MFN) duty, not instead of it.
Because the layers stack on the same customs value, a Chinese steel product can carry its base duty plus a 50% Section 232 tariff (main list, as of November 2026) plus a 25% Section 301 tariff — an effective rate of 75% or more before fees and tax. The 2024–2025 USTR review pushed several 301 categories far higher: electric vehicles to 100%, with steep increases on solar cells, semiconductors, batteries, and critical minerals.
Section 232 tariffs are national-security duties on steel and aluminum (and derivatives) from covered countries. Section 301 tariffs are trade-remedy duties specifically on China-origin goods. Both are extra duties added on top of the normal HS-code rate.
Yes. They're additive. A product can owe its base MFN duty plus a Section 232 tariff plus a Section 301 tariff, all calculated on the same customs value — which is why effective rates can exceed 50%.
Historically 25% on Lists 1–3 and 7.5% on List 4A, but the 2024–2025 USTR review sharply increased many categories — for example, 100% on electric vehicles, with higher rates on solar cells, semiconductors, batteries, and critical minerals. Rates change often; confirm the current figure for your HS code with USTR/CBP.
Sometimes. Correct HS classification, active product exclusions, sourcing from outside China (with genuine substantial transformation), USMCA-origin North American goods, and tools like foreign-trade zones or duty drawback can each reduce or defer exposure. Talk to a customs broker before restructuring.
No — it focuses on the duty + 232/301 tariff layers. For total landed cost including MPF, HMF, and sales tax, use our Customs Duty Calculator.
