Tariff & Import Duty Estimator

About this tool

This free import duty estimator is for e-commerce sellers, importers, procurement teams, and small-business owners who need a fast estimate of US tariffs and total landed cost before committing to a sourcing decision. It computes Most Favored Nation (MFN) duty, the Section 122 global surcharge, applicable Section 232 tariffs (steel, aluminum, autos), Section 301 China-specific rates, the Merchandise Processing Fee, and the Harbor Maintenance Fee — the same fee components your customs broker will calculate, but for free, in your browser, with no signup. The 2026 tariff landscape moves quickly: surcharges are added, expanded, and retired on weekly news cycles. This tool's rate data is verified against US Trade Representative (USTR) and White House proclamations and updated on the date shown above.

How it works

1. Pick your country and product category. The category maps to a Harmonized System (HS) chapter, the same two-digit prefix US Customs uses to classify imports. We use the high-end MFN rate within each chapter so the estimate stays conservative — you'd rather see a duty bill that turns out to be lower than estimated than one that surprises you at customs.
2. Enter your declared value, shipping, and insurance. Duty is calculated on the declared value (not on shipping or insurance), but the total landed cost includes all three plus the duty and processing fees. Toggle Ocean shipment if you're shipping by sea — that adds 0.125% Harbor Maintenance Fee per 19 CFR 24.24.
3. Read the breakdown. The results panel shows each component (MFN, Section 122, Section 232, Section 301, MPF, HMF) separately so you can see exactly which provisions are driving your duty bill — and whether sourcing from a different country would help. Toggle the country-comparison view to see the same product priced across China, Mexico, Vietnam, India, and Canada side-by-side.

Current Tariff Landscape (2026)

After the Supreme Court struck down the IEEPA-based reciprocal tariffs in February 2026, the administration replaced them with a Section 122 surcharge: a 10% ad valorem global tariff active for 150 days from February 24, 2026, expiring July 24, 2026. The surcharge does NOT stack with Section 232 — goods already covered by Section 232 (steel, aluminum, autos) are exempt from the 10% addition — and USMCA-qualifying goods from Canada and Mexico are carved out entirely.

Section 232 tariffs on steel, aluminum, and copper have been restructured twice in 2026: a April 2, 2026 proclamation (effective April 6) moved the headline rate from the original 2018 flat 25% to 50% on articles wholly or almost wholly of steel, aluminum, or copper, 25% on listed derivative articles, and a 15% transitional rate for certain industrial and grid equipment through the end of 2027 — with reduced rates for UK-origin goods and for articles made entirely of US-smelted metal. A June 1, 2026 proclamation widened product coverage and eased the domestic-content threshold; a July 20, 2026 proclamation added an aluminum onshoring-incentive program without changing the base rates. Vehicles and auto parts (25%) joined Section 232 in 2025. In April 2026 the administration also proclaimed Section 232 tariffs on pharmaceuticals (chapters 29 and 30) at a headline rate of 100%, with reduced tiers for companies with onshoring plans (20%) or Most-Favored-Nation pricing agreements (0%), and country-specific reductions for the EU/Japan/South Korea/Switzerland (15%) and the UK (10%). The pharma tariffs take effect July 31, 2026 for 17 named major drug companies and September 29, 2026 for all others — this calculator will start applying them automatically on those dates.

Section 301 tariffs on China remain in place: chapter-modal 25% for industrial goods on Lists 1-3 (chemicals, plastics, steel articles, machinery, electronics, autos, optics) and 7.5% for consumer goods on List 4A (apparel, footwear, furniture, toys, leather goods). Specific subheadings carry elevated rates that the chapter-modal estimate doesn't capture: electric vehicles (HTSUS 8703.80, 8703.90) at 100%, solar cells (8541.40) at 50%, lithium batteries (8507.60) at 25-50%, semiconductors at 50%. The breakdown panel surfaces a footnote when your selected chapter has elevated subset rates so you know to verify with a broker.

A separate Section 301 action targeting forced-labor enforcement failures took effect the same moment the Section 122 surcharge expired — 12:01am ET on July 24, 2026 — across 60 economies, including most of the countries this calculator supports. Unlike Section 122, it has no expiration date and no USMCA carve-out: Canada and Mexico are named at a flat 10% rate without qualification, so USMCA-qualifying goods from those two countries can still show a nonzero duty from this layer alone. Rates run 10% or 12.5% flat for most economies, and a net-of-MFN formula for the EU, Taiwan (10% net), and Japan, South Korea, and Switzerland (12.5% net) — the additional duty tops up the existing MFN rate to the target, then drops to zero once MFN alone reaches it. It does not stack with goods already covered by a Section 232 action (steel, aluminum, copper, autos, pharmaceuticals).

Frequently asked

Why is my estimate higher than another calculator?

We use the high-end MFN rate within each HS chapter, not the average or modal rate. For most importers, the precise rate on their specific subheading is lower — but using the high end means we never under-estimate, which would set the wrong expectation for your cash-flow planning. The forthcoming paid tier classifies your product into the exact HTSUS subheading and quotes the precise rate.

Does the 10% surcharge stack with the 25% Section 232 steel duty?

No. The Section 122 proclamation explicitly states the surcharge "shall not apply in addition to tariffs imposed under section 232." Steel (chapter 72), steel articles (73), aluminum (76), and autos/parts (87) are not subject to the 10% addition.

What if my goods qualify under USMCA?

Check the USMCA box (visible when Canada or Mexico is selected). The calculator zeroes the MFN rate and (while it was in effect) exempted you from Section 122. It does not remove the Section 301 forced-labor tariff that took effect July 24, 2026 — that action names Canada and Mexico at a flat 10% with no USMCA exemption in its text, so USMCA-qualifying goods from those two countries can still show a nonzero duty from that layer alone. USMCA qualification depends on Regional Value Content rules; you must self-certify and retain documentation. We don't model the qualification logic — that's a separate determination.

Is the Merchandise Processing Fee always charged?

Only on formal entries — declared value at or above $2,500. For smaller informal entries, MPF is replaced by a flat fee not captured here. The MPF rate is 0.3464% with a $31.67 minimum and a $614.35 maximum (19 CFR 24.23).
