US Tariff Rate Calculator
Enter an HS code and where the goods are coming from, and get the whole stack — MFN base rate, Section 301, Section 232, and the USMCA rate if it qualifies — each one with the notice and date behind it. Every number comes from the tariff database, never an AI, and a layer that can't be verified is flagged, not guessed. Free, no signup, unlimited lookups; try the sample to preview the CSV and Entry Memo, or subscribe to export your own.
Every layer, shown.
MFN base rate, Section 301 (China lists 1-4A), the Section 301 forced-labor action (10% or 12.5% by origin tier, 60 economies), Section 232 tiered rates for steel/aluminum/copper (50% Annex I-A primary, 25% Annex I-B derivative, 10% US-melt, 15% UK, 200% Russia aluminum) per Apr 6 2026 Proclamation, and USMCA preferential rates — stacked exactly as CBP calculates.
Automatic detection of AD/CVD orders, Section 301 exclusions, Section 232 melt/pour exemptions, and USMCA qualification requirements. Know your risk before you file.
Complete US HTS 2026 tariff schedule with all policy overlays. Updated when the Federal Register publishes changes. Database-driven, not hardcoded.
Three inputs to a defensible number.
Type the 8-digit HS code, pick origin and destination. The tool resolves it to the correct 10-digit filing suffix for you.
See the MFN base rate plus every active layer: Section 301 including the forced-labor action and Section 232, each with its Chapter 99 code and Federal Register citation.
The CSV carries the complete duty stack, filing codes, and policy basis. Try the sample to preview it — export on your own entries requires a subscription.
Anyone who needs the real number.
Know the real landed duty before you commit to a supplier or a PO. The calculator stacks every active tariff, so the cost isn't a surprise at the border.
Every rate comes with its Chapter 99 code and Federal Register citation, so the duty you file is one you can defend in a CBP review.
Compare origins before you move sourcing. The built-in Mexico/USMCA comparison shows the duty differential on the same product.
Frequently Asked Questions
What is the current US tariff rate for Chinese imports?
Chinese imports face multiple layers: (1) MFN base rate (varies by HS code, typically 0-20%), (2) Section 301 tariffs on listed goods (7.5%-100% depending on the list), and (3) the Section 301 forced-labor tariff, which for China is a flat 12.5% under HTSUS heading 9903.05.31, effective July 24, 2026. Use the tariff calculator to get the exact stack for your HS code.
Is the Section 122 tariff still in effect?
No. Section 122 of the Trade Act of 1974 imposed a 10% broad-based tariff from February 24, 2026, but its authority is capped at 150 days under 19 U.S.C. § 2132 and it expired on July 24, 2026. Congress did not extend it, and the President has no unilateral authority to do so. Do not file Chapter 99 heading 9903.03.01 on entries made on or after July 24, 2026. The tariff calculator stops applying Section 122 automatically based on your entry date.
What replaced the Section 122 tariff?
A Section 301 forced-labor action took effect at the same moment Section 122 expired, 12:01 a.m. ET on July 24, 2026. It applies an additional duty to imports from 60 economies found to have failed to impose or effectively enforce a prohibition on goods produced with forced labor: 10% for some economies and 12.5% for others, depending on the tier assigned to the origin. Authority: USTR Docket Nos. USTR-2026-0265 and USTR-2026-0266, and the Presidential Memorandum of July 23, 2026.
Are USMCA goods exempt from the Section 301 forced-labor tariff?
Canada-origin and Mexico-origin goods entered free of duty under USMCA are exempt, Canada via HTSUS heading 9903.05.93, Mexico via 9903.05.94. Declared origin alone is not sufficient: the good must actually qualify for USMCA preferential treatment, meaning the applicable rule of origin is met and a Certificate of Origin supports it. Articles already subject to Section 232 are also exempt, because the two do not stack.
How is the Section 301 China action different from the forced-labor action?
They are separate actions under the same statute and they stack. The China-specific Section 301 action applies only to goods of China listed on Lists 1 through 4A, at 7.5%-100% depending on the list. The forced-labor action applies to all products of 60 investigated economies regardless of list membership, at a flat 10% or 12.5% by tier. A China-origin good on a Section 301 list can carry both.
What is an MFN tariff rate?
MFN stands for Most Favored Nation. It is the base tariff rate that the US applies to imports from any WTO member country that has not negotiated a separate free trade agreement with the US. The MFN rate is the floor before any policy surcharges (Section 301, Section 232, AD/CVD) are added. Free trade agreement partners such as USMCA countries get preferential rates below the MFN rate.
Why does the calculator ever say "unknown" or "needs broker verification" instead of a rate?
Because it does not guess. If a duty layer cannot be traced to a verifiable source, the result says so and flags the entry for broker review instead of inventing a number. A stated gap with a paper trail holds up at an audit; a confident rate with nothing behind it does not. That willingness to say "unknown" is the point of the tool.
Why does the duty rate depend on my entry date, not today's date?
Because duty is charged under the law in force on the day the goods enter, not the day you look them up. Give the calculator an entry date and it prices against the rules in force that day, so a layer that began in 2026 cannot reach a 2025 entry. Leave the date blank and it uses today's law, which is only right if the shipment has not moved yet.
How should I use this duty stack — is it the final number to file?
Use it as your starting point, not a filed number. MFN, Section 301, and Section 232 are calculated from the database for your exact HS code and origin. AD/CVD is checked automatically on every lookup too — when an active order exists but no producer-specific rate applies, the total shown uses a maximum-liability default, not the rate for your specific exporter. Confirm the exact producer rate with your broker before filing; do not file off a maximum-liability default.
What does a worked example look like — MFN, Section 301, and the forced-labor tariff stacked?
For a cotton knit sweater (HS 6110.20.20) from China: MFN base rate 16.5%, plus the Section 301 China-list tariff 7.5%, plus the Section 301 forced-labor tariff 12.5% (HTSUS 9903.05.31) — a total duty stack of 36.5%. Section 232 does not apply; this HS code is not a steel, aluminum, or copper derivative. Run your own HS code and origin above for the current, dated stack.
Need the full answer, not just the rate?
Turn any result into a dated, verifiable record. The Entry Memo captures the full duty stack, the Federal Register citation behind every rate, the entry date, a stable ID, and an integrity hash, $99/month for 20 memos, $15 each after.
