Tariff Calculator

Pick what you are importing and where it comes from, enter the customs value, and you get the full duty stack as CBP would assess it in 2026: the base HTS rate pulled from the government schedule, the Section 301 tariff for that country, any Section 232 duty, and the entry fees, plus the same shipment priced from five other origins. Slide the pass-through control to see what to charge.

How the tariff calculator works

If you import anything into the United States in 2026, the duty on it is a stack, not a single number, and the stack changed shape on July 24. This page builds it the way CBP does. It starts with the base rate for your product, which we pull code by code from the government's own Harmonized Tariff Schedule rather than typing in from memory. It adds the Section 301 forced-labor tariff for the country of origin: 10 percent for seventeen economies, 12.5 percent for most of the rest, and a combined-rate ceiling for the European Union, Taiwan, Japan, Korea, and Switzerland. Where a Section 232 duty applies (steel, aluminum, copper, vehicles), it uses that instead, because the two are not allowed to stack. For goods from China it can add the older China-specific lists on top. Then it adds CBP's two entry fees, which almost every online estimate forgets and every real entry includes.

Two things make it more useful than a rate lookup. The pass-through slider turns the duty into a pricing decision: how much of the bill you recover from customers and what that does to your price. And the comparison table prices the same shipment from five other origins, because in 2026 the country on the label moves the bill more than the product does.

How do you calculate import duty?

Take the customs value (the price you paid for the goods, without international freight and insurance) and multiply it by each rate that applies, then add the fees. In 2026 the rates are the base HTS rate, the Section 301 forced-labor tariff for the origin, and for metals and vehicles a Section 232 duty in place of the Section 301 one. A $12,500 shipment of cotton T-shirts from Vietnam pays 16.5 percent base duty ($2,062.50) plus 12.5 percent Section 301 ($1,562.50), then $43.30 of merchandise processing fee and $15.63 of harbor maintenance fee, for $3,683.93 in all.

The formula

base duty = customs value × HTS column 1 rate (or the trade-agreement rate if the goods qualify)
Section 301 = customs value × country tier (10% or 12.5%), or the gap up to a capped combined rate
Section 232 = customs value × 50% (steel, aluminum, copper) or 25% (vehicles and covered parts), replacing Section 301
China lists = customs value × 7.5%, 25%, 50%, or 100% for goods of China on a list
fees = MPF (0.3464%, floor $33.58, ceiling $651.50) + HMF (0.125% by ocean)
total = base duty + Section 301 + Section 232 + China lists + fees

Every rate is charged on the customs value, so the layers add rather than compound: a 16.5 percent base rate and a 12.5 percent tariff make 29 percent, not 30.6. The merchandise processing fee floor and ceiling step up to $34.58 and $670.86 on October 1, 2026, and the page switches on that date by itself. Entries under $2,500 are informal and pay a flat $2.69 instead of the percentage.

Worked example

$12,500 of cotton T-shirts from Vietnam, arriving by ocean. The schedule's rate for HTS 6109.10.00 is 16.5 percent, so the base duty is 12,500 × 0.165 = $2,062.50. Vietnam is in the 12.5 percent tier: 12,500 × 0.125 = $1,562.50. The merchandise processing fee is 12,500 × 0.003464 = $43.30, above the floor and below the ceiling, and the harbor maintenance fee is 12,500 × 0.00125 = $15.63. Total: $3,683.93, an effective 29.47 percent of the customs value.

The same shirts from Mexico, qualifying under the USMCA, pay no base duty (the agreement rate is Free) and no Section 301 tariff (USMCA-qualifying goods are exempt), so the whole bill is the $58.93 of fees. From Germany the base rate is still 16.5 percent, but the European Union's combined ceiling is 10 percent, which the base rate already beats, so the Section 301 line is zero and the bill is $2,121.43. From India, in the 10 percent tier, it is $3,371.43. From China, with the 7.5 percent List 4A duty that apparel carries, it is $4,621.43.

Pricing it: pass all $3,683.93 through on goods you sell for $30,000 and the new price is $33,683.93, up 12.28 percent. The tariff stack is 29 percent; the price move is 12, because duty is charged on what you paid, not on what you charge.

Origin moves the bill more than the product does

Run the example above and look at the comparison table rather than the headline. The product never changed; the bill ran from $59 to $4,621. That spread is the story of 2026 importing. The old instinct was to memorize product rates (apparel is expensive, electronics are free, furniture is free), and those rates still matter, but the country layer now decides the bill for most goods: a 12.5 percent tier, a 10 percent tier, a combined ceiling that can zero the tariff out entirely when the base rate is already high, a trade agreement that removes both layers at once, and a Section 232 program that swaps the tariff for a bigger one. The only number you should carry in your head now is the one for your own origin, and this page will give it to you for any of the sixty economies.

The ceilings deserve a second look, because they are counterintuitive in a helpful way. A European sweater at a 16.5 percent base rate pays no forced-labor tariff at all, since the base rate already exceeds the 10 percent combined ceiling; a European microwave at 2 percent pays 8 percent of tariff to reach it. Japan, Korea, and Switzerland work the same way at 12.5 percent. Duty-free products from those five economies therefore pay the full ceiling, and heavily dutied ones pay nothing extra.

What changed on July 24, 2026, and what did not

The Supreme Court struck down the emergency-powers tariffs in February 2026, and a flat 10 percent Section 122 surcharge filled the gap for 150 days. When that clock ran out on July 24, the Section 301 forced-labor action took over the same moment, with the 10 and 12.5 percent tiers this page uses. Three things did not change and are still on the bill. The Section 232 tariffs on steel, aluminum, copper, and vehicles were never part of the court case and stand at 50 and 25 percent (15 percent all-in for vehicles from the European Union, Japan, and Korea under their deals). The China-specific Section 301 lists from 2018 to 2024 are still in force and stack on top of the new tier, which is why the calculator asks which list your product is on. And the $800 de minimis exemption is gone for good: it ended August 29, 2025, so a small parcel is dutiable exactly like a container, with only a smaller flat processing fee to soften it.

What this page deliberately does not model

Antidumping and countervailing duties, which are product-and-company specific and can dwarf everything here (solar panels and some steel products are the famous cases). Tariff-rate quotas, including the new textile quotas for Bangladesh, Cambodia, Indonesia, and Malaysia. Product exclusions and the exempt annexes, which cover about 2,100 codes, many of them for aircraft and pharmaceutical use only. Specific and compound rates (cents per kilogram plus a percentage), which is why a few everyday products such as wine and some hats are absent from the category list. The metal-content rule for Section 232 derivatives, where a product that merely contains steel pays the 50 percent on the steel's value rather than the whole article; the page's metal categories are all-metal articles where the two are the same. The separate Section 301 action on Brazil. And the customs valuation questions a broker earns a living on, such as assists, royalties, and first-sale pricing. We would rather show you the shape of the bill honestly, with each layer labeled, than pretend a web page can replace the entry. If your broker's number differs from ours, the broker is right, and the difference is usually one of the items in this paragraph.

A word for the person doing this for the first time

Most people who land here are not customs professionals. They are a small shop owner pricing a first container, a maker whose supplier just raised a quote, or someone who ordered a $300 gadget and got a bill from the carrier. The arithmetic is honestly simple once the layers are named, and that is what this page is for: you can see every line, change one input, and watch which layer moved. The rates themselves are set in Washington and will change again; the way they stack will not. Learn the stack once and every future rate announcement becomes a one-line edit to a bill you already understand.

Frequently asked questions

How do I calculate import duty on a shipment in 2026?

Multiply the customs value (what you paid for the goods, before freight and insurance) by each rate that applies, then add them up. In 2026 that is usually three layers: the base HTS rate for the product, the Section 301 forced-labor tariff for the country of origin (10 percent or 12.5 percent for most of the world since July 24, 2026), and, for steel, aluminum, copper, and vehicles, a Section 232 duty instead of the Section 301 one. Then add CBP's merchandise processing fee and, for ocean freight, the harbor maintenance fee. This calculator does all of it and shows every line.

What is the Section 301 tariff that started on July 24, 2026?

It is an additional duty on nearly all imports from 60 economies, imposed after Section 301 investigations into forced-labor import bans. Seventeen economies that have or have committed to such a ban pay 10 percent (Canada, Mexico, India, the United Kingdom, Indonesia, Malaysia, and others); everyone else on the list pays 12.5 percent. The European Union and Taiwan are capped so that base rate plus tariff equals 10 percent, and Japan, Korea, and Switzerland are capped at 12.5 percent combined. It replaced the flat 10 percent Section 122 surcharge that expired the same day.

Why does the calculator show no Section 301 tariff on steel or cars?

Because goods already covered by Section 232 national-security tariffs are exempt from the forced-labor Section 301 duty, to avoid stacking. They pay the Section 232 rate instead: 50 percent on steel, aluminum, and copper articles, and 25 percent on passenger vehicles and covered parts (15 percent all-in for vehicles from the European Union, Japan, and Korea under their trade deals). The base HTS rate still applies on top of the metals duties.

Do goods from Mexico and Canada pay the new tariff?

Not if they qualify under the USMCA. Goods entered free of duty under the agreement are exempt from the Section 301 forced-labor tariff, so a USMCA-qualifying shipment from Mexico pays no base duty and no Section 301 duty, only CBP's entry fees. Goods that do not meet the rules of origin pay the normal base rate plus 10 percent. Choose the qualifies-or-not toggle to see both.

Does the China tariff stack on top of the July 2026 tariff?

Yes. The older China-specific Section 301 lists are separate and still in force: 25 percent on Lists 1, 2, and 3 (machinery, electronics, furniture, auto parts, building materials), 7.5 percent on List 4A (most consumer goods), and 50 or 100 percent on strategic products such as semiconductors, solar cells, and electric vehicles. Pick your product's list in the calculator and it adds that duty on top of the base rate and the 12.5 percent forced-labor tariff.

Is customs value the same as what I paid?

For most commercial shipments, yes: the transaction value is the price actually paid or payable for the goods, not including international freight and insurance. Duty is charged on that number, not on the landed cost, which is why this page asks for it separately from your selling price. If your supplier's invoice bundles freight in, back it out before entering the value.

Is there still an $800 duty-free limit for small packages?

No. The de minimis exemption ended for all countries on August 29, 2025, and the postal transition rules ran out on February 28, 2026. Any commercial import is now dutiable at the same rates regardless of value; the only concession for small shipments is that entries under $2,500 use a flat $2.69 processing fee instead of the percentage fee.

What are the MPF and HMF on the fee lines?

The merchandise processing fee is CBP's charge for handling the entry: 0.3464 percent of the customs value, but never less than $33.58 nor more than $651.50 per formal entry (rising to $34.58 and $670.86 on October 1, 2026), or a flat $2.69 for an informal entry under $2,500. The harbor maintenance fee is 0.125 percent of the value on goods arriving by ocean and is not charged on air, truck, or rail freight.

How much of a tariff should I pass on to my customers?

That is a pricing decision, and the slider lets you test it. At 100 percent you raise prices by the whole duty and your margin dollars are unchanged; at 0 percent you absorb it and your margin shrinks by the full amount. Most businesses land in between, and the useful number is the price increase as a percentage of what you charge, which is usually far smaller than the tariff rate because your selling price is higher than the customs value the duty is charged on.

Why might my broker's number differ from this one?

Several honest reasons: your exact 10-digit classification may carry a different base rate than the category here, your product may have an exclusion or fall in an exempt annex, antidumping or countervailing duties may apply, textile shipments from some countries have quota rates, and derivative metal products pay the Section 232 duty only on their metal content. Treat this page as the shape of the bill and the broker's entry as the bill.
