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.
Tariffs Tool is built and operated by Master Plan Bookkeeping, an accounting, bookkeeping, and tax practice serving business owners nationwide. The same team behind the numbers here handles books, tax preparation, and planning for importers and other businesses every day.
What We Cover
Full calculator profiles cover 51 countries and 14 product sectors, including:
- Standard MFN (Most Favored Nation) tariff rates
- Section 301 forced-labor tariff (10%/12.5% two-tier) — replaced the flat 10% Section 122 tariff on July 24, 2026, which itself replaced 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
Curated static snapshot compiled from the USITC Harmonized Tariff Schedule, USTR Section 301 notices, and presidential proclamations. Not a live USITC feed. Country baselines and Section 232/301/338/forced-labor layers last verified 2026-10-23. The prior full-table stamp is 2026-10-09. The change log’s newest effective event is 2026-10-30; that date does not by itself revise these tables. Verify binding rates at https://hts.usitc.gov/.
The snapshot is compiled from these 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
Some tariffs stack and some do not. The calculator adds the Section 301 forced-labor tariff (or the EU 15% ceiling) on ordinary goods, China Section 301 where it applies, and Section 232 on covered articles. It does not add the forced-labor layer on top of Section 232 steel, aluminum, or copper: a wholly-steel article is 50% under Section 232, not 60%, and Chinese wholly-steel is 75% (50% Section 232 plus 25% China Section 301), not 85%. IEEPA reciprocal tariffs are not in the current stack — they were struck down and are tracked only as a refundable amount. Actual rates may vary by specific HTS code at the 8-10 digit level — see HTS code vs HS code for how the 10-digit classification drives your rate. And every dollar of these duties is paid by a US importer, not by the exporting country — here's who actually pays.

The current data reflects rates as of 2026-10-23. 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 carries a 150-day time limit — it expired on July 24, 2026 and was replaced the same day by the Section 301 forced-labor tariff, a two-tier 10%/12.5% duty on roughly 60 economies (most major exporters, including China and Vietnam, are in the 12.5% tier).
- • Section 232: Steel 50%, Aluminum 50% (UK: 25%)
- • Section 232: Autos 25%, Copper 50%
- • Section 232: Semiconductors ~25%, Lumber ~10% (as of mid-2026)
- • Section 301 on China: 7.5-100%
- • 25 states challenging the forced-labor tariff in CIT (filed Aug 2026; CBP still collecting)
