US tariff estimator
US import duty is the MFN rate for the HTS code, plus any extra duties that apply to the product and country, plus fees. This estimator takes the country of origin, HTS code and value, lists the tariff actions in our tracker that may apply, links each to its official source, and adds up the rates you confirm. It is an estimate, not legal advice: confirm with a licensed customs broker before you price or file.

Runs in your browser. Nothing you type is uploaded. The list comes from Morsa's tariff tracker; each action links to its official source. Canada's and Mexico's own duties on US goods are in the tracker, not in this estimate.
How the estimate is built
| Part | Where the number comes from |
|---|---|
| MFN duty | The column 1 general rate for your full 8 or 10 digit HTS code, filled in from the USITC’s official schedule (2026 HTS Revision 21). You can change it. Specific rates such as cents per kilogram are shown but not converted: enter their percent of value yourself. |
| Extra duties | Section 232, 301, 338 and 201 actions and antidumping or countervailing duty orders from our tariff tracker that match your country and chapter or product family. You tick the ones that apply and can change each rate and the value it applies to. |
| USMCA | For goods of Canada or Mexico that qualify and have a certification, tick the claim. The estimator counts the MFN duty as zero (check the HTS “Special” column for your code’s USMCA (S) rate), drops the merchandise processing fee for originating goods, and drops every action whose own text exempts USMCA goods, such as the Section 301 duty on 60 economies (headings 9903.05.93 for Canada and 9903.05.94 for Mexico). Section 232 duties still apply, some only to non-US content; each row shows its USMCA text. |
| Merchandise processing fee | 0.3464% of value on formal entries, at least $34.58 and at most $670.86 from October 1, 2026. |
| Harbor maintenance fee | 0.125% of value on cargo unloaded from a ship at a listed US port. |

The tracker data in the estimator is dated, and the page shows the date. Today it covers 88 actions that are in effect, scheduled, proposed or paused (73 in effect), each linked to its Federal Register notice, proclamation or CBP message. IEEPA tariffs are left out: the Supreme Court ruled on February 20, 2026 that IEEPA does not allow tariffs, and those duties have ended.
Why it does not give one number on its own
Extra duties depend on things a short form cannot know: the exact 8- or 10-digit HTS line, whether the product is on an annex list, how much of the value is steel or copper, which producer made it, whether an exclusion applies, and how actions stack. So the estimator shows what may apply and why, pre-ticks only the rows that match your chapter, product family or country by name where the tracker states a rate, and lets you correct the rest. Where a program has several rates, the suggestion is the highest one the tracker states. Where our data states no single rate, the row says so and is not counted until you enter one, so the total can be too low as well as too high: read every row listed.
The tariff programs it covers
| Authority | What it is | Who sets it |
|---|---|---|
| Section 232 | Duties on imports that threaten national security: steel, aluminum, copper, autos and parts, trucks, lumber, semiconductors and more | The President, after a Commerce investigation |
| Section 301 | Duties against unfair trade practices, such as the China lists and the 2026 actions on 60 economies and on Brazil | USTR |
| Section 338 | Duties against countries that discriminate against US commerce, used on certain Canadian products in 2026 | The President |
| Section 201 | Safeguards against import surges, such as the 2026 quota on quartz surface products | The President, after a USITC finding |
| AD/CVD | Antidumping and countervailing duties on specific products from specific countries, at producer-specific rates | Commerce and the USITC |
How to use it
Enter the country where the goods were made, not where they ship from.
Enter the HTS code, or at least the 2-digit chapter, and pick a product family if you know it.
Enter the customs value in US dollars, usually the price paid without international freight and insurance.
Check the MFN rate. A full code fills it from the official HTS; a specific rate (cents per kilogram, for example) needs its percent of value entered by hand. You can always look the code up on the official HTS.
Read each program and order listed. Tick the ones that apply, fix the rate, and enter a smaller value where a duty applies to the metal content only.
Take the result and the source links to your customs broker.
Common questions
Is this the duty I will pay?
Not necessarily. It is a starting point built from the rates you enter and confirm. Your broker files the entry and CBP decides the duty. Classification, valuation, origin and exclusions can each change the answer.
Where does the MFN rate come from?
From the “General” column of the Harmonized Tariff Schedule the US International Trade Commission publishes (2026 HTS Revision 21, released 10/09/2026). Type a full 8 or 10 digit code and the rate fills in, with a link to that line on hts.usitc.gov. Rates set in cents or dollars per unit are shown as printed, not converted, because their percent of value depends on your price. The field stays editable if your broker gives you a different rate.
Do USMCA goods pay these tariffs?
Qualifying goods get the USMCA rate in place of the MFN rate (check the HTS “Special” column for S) and pay no merchandise processing fee (19 CFR 24.23(c)(3)). The Section 301 duty on 60 economies does not apply to goods of Canada or Mexico entered duty free under USMCA (U.S. note 52(g) and (h)), so with the claim ticked a USMCA valve that would otherwise pay 10% pays only the harbor maintenance fee by sea. Section 232 duties still apply to USMCA goods: steel, aluminum and copper in full, while qualifying autos and trucks pay on their non-US content only and qualifying auto and truck parts are not charged until a process for charging their non-US content is in place. Each action’s USMCA treatment shows in the list when you pick Canada or Mexico. Make the certification with the USMCA generator.
Can I save or share the result?
Yes. “Copy result” puts every line, with its chapter 99 heading where our data names one, on your clipboard as plain text, and “Print” prints just the result.
Where do the tariff actions come from?
From Morsa’s US tariff tracker, which records each action from its primary source. Every row in the estimator links to the tracker entry and to the source document.
WHERE MORSA FITS
A duty changed. Do your open orders know?
When a tariff moves, ship dates, landed costs and customer promises move with it. Morsa follows up with suppliers on open purchase orders and the documents each shipment needs, and keeps the dates you give customers current, in whatever channels your team already works in.
