About Tariffs Tool
Tariffs Tool is a free resource for estimating US import duties and understanding the tariff landscape. We help importers, businesses, journalists, and policy researchers quickly assess the cost impact of US trade policy.
What We Cover
Our database covers 36 countries and 14 product sectors, including:
- Standard MFN (Most Favored Nation) tariff rates
- Section 122 global tariff (10%, effective Feb 24, 2026) — replaces IEEPA tariffs struck down by SCOTUS
- Section 301 tariffs (China) — 7.5% to 100%
- Section 232 tariffs (steel 50%, aluminum 50%, copper 50%, autos 25%)
- Trade agreement preferences (USMCA, KORUS, AUSFTA, etc.)
- Merchandise Processing Fee (0.3464%) and Harbor Maintenance Fee (0.125%)
Our Methodology
We provide rates at the product sector level (e.g., "Electronics", "Clothing") rather than at the individual HTS 8-digit level. This gives useful directional guidance while acknowledging that the exact rate depends on the specific product classification. When a sector contains a wide range of rates, we use the most common representative rate.
Data Sources
All tariff data is compiled from official US government and authoritative research sources:
- USITC Harmonized Tariff Schedule — the official US tariff database
- US Trade Representative (USTR) Section 301 Actions — additional duties on Chinese goods
- Commerce Department Section 232 — steel and aluminum tariffs
- Congressional Research Service Tariff Tracker — nonpartisan policy analysis
- Tax Policy Center Tariff Tracker — revenue and household impact analysis
- Penn Wharton Budget Model — economic impact modeling and USMCA utilization data
- Supreme Court opinion: V.O.S. Selections Inc. v. United States (Feb 20, 2026)
- Section 122, Trade Act of 1974 (19 U.S.C. § 2132) — 10% global tariff signed Feb 20, 2026
- White House executive orders on reciprocal tariffs (April 2025) — STRUCK DOWN by SCOTUS
- Published trade agreement texts (USMCA, KORUS FTA, AUSFTA, etc.)
- Official Executive Orders and Presidential Proclamations
Tariff Stacking
Many tariffs stack on top of each other. Our calculator accounts for reciprocal tariffs, Section 232 (steel/aluminum/copper/lumber), and Section 301 (China) where applicable. For example, a Chinese steel import may face MFN duties + Section 301 + Section 232 + reciprocal tariffs simultaneously. Actual rates may vary by specific HTS code at the 8-10 digit level.
Rates last verified: February 21, 2026
Update Methodology
Rates are reviewed and updated when significant tariff changes are announced — including executive orders, Section 301 list modifications, Section 232 proclamations, and trade agreement implementations. The current data reflects rates as of 2026-03-20. The "Updated" badge appears on every page to show when our data was last verified.
SCOTUS Strikes Down IEEPA Tariffs — Trump Signs 10% Replacement Same Day
The Court ruled 6-3 in V.O.S. Selections Inc. v. United States that IEEPA does not authorize tariffs. Chief Justice Roberts wrote the majority opinion. Justices Kavanaugh, Thomas, and Alito dissented. All IEEPA reciprocal tariffs on 80+ countries are invalidated.
Trump signed a 10% flat tariff on ALL countries the same evening under Section 122 of the Trade Act of 1974. Effective February 24, 2026. Section 122 has a 150-day time limit — expires approximately July 24, 2026 unless Congress extends. The administration is launching Section 301 investigations for more permanent tariffs.
- • Section 232: Steel 50%, Aluminum 50% (UK: 25%)
- • Section 232: Autos 25%, Copper 50%
- • Section 232: Semiconductors 25%, Lumber 10%
- • Section 301 on China: 25-100%
- • 24 states challenging Section 122 in CIT (filed March 5)
Companies that paid IEEPA tariffs may be eligible for refunds, but the Trump administration is NOT voluntarily issuing them. Trump: "it has to get litigated for the next two years." Consult a trade attorney about filing claims.
