US Tariff Calculator

The calculator takes three inputs, an HTS code, a customs value, and a country of origin, and returns an estimated total duty. It looks up the most-favored-nation base rate tied to your HTS classification, then adds the origin-specific layers that apply, Section 301 on Chinese goods, Section 232 steel and aluminum duties, any IEEPA-based rate, the Section 122 baseline, and any antidumping or countervailing orders. All of those rates are applied to the customs value you declare to produce a single dollar figure. The point is to show the real all-in duty rather than just the headline base rate, which on many imports is the smallest part of the bill. The result is an estimate for planning, not a binding customs ruling, so treat it as a fast screen before you commit to a supplier or file an entry.

It combines up to six layers into one number. First is the MFN base rate from the Harmonized Tariff Schedule, the duty every normal-trade-relations origin pays. On top of that sit the trade-policy measures that depend on origin and product: Section 301 tariffs on goods of Chinese origin, Section 232 duties on certain steel and aluminum, IEEPA-based tariffs on select origins, the Section 122 baseline where it is in force, and any antidumping or countervailing duty orders on your specific product. Not every layer applies to every shipment, so the calculator only stacks the ones triggered by your HTS code and country of origin. That is why two products with the same base rate can carry very different total duty once the applicable layers are added against your declared customs value.

Because origin decides which trade-policy layers apply. The MFN base rate is the same for most origins, but Section 301 attaches only to goods of Chinese origin, Section 232 and IEEPA measures vary by country, and a free trade agreement can drop the base rate to zero for a qualifying origin. Enter the wrong origin and the calculator will stack the wrong add-ons, so the total will be off in either direction. Origin is also a legal question, not just where the goods shipped from, since substantial transformation determines the country of origin for duty purposes. If your product is assembled from components across several countries, or routed through a third country, confirm the origin with a broker before you rely on the estimate, because a misstated origin is a common source of entry errors and penalties.

Enter the customs value that duty is assessed on, which for most shipments is the transaction value, the price actually paid for the goods, and often the CIF value that includes cost, insurance, and freight to the United States port. Duty scales directly with this number, so the value you enter matters as much as the rate. Certain additions such as assists, royalties, or packing can raise the dutiable value, while some international freight and insurance may be treated differently depending on the terms. The calculator applies every rate to the value you provide, so a rough value gives a rough estimate and an accurate value gives a usable one. If your Incoterms or valuation are complicated, a broker can confirm the correct dutiable base before you rely on the figure.

Not exactly. The calculator produces a close estimate based on the HTS code, customs value, and origin you enter, but the duty on the actual entry depends on the final classification, the verified customs value, the precise rates in force on the entry date, and any exclusions or special programs that apply to your goods. It also does not include merchandise processing fees, harbor maintenance fees, or brokerage charges, which are separate line items on a landed-cost bill. Treat the result as a planning number that is usually within range, then confirm the exact duty with a licensed broker before you file. The estimate is designed to stop surprises early, when you are still choosing a supplier or sizing a purchase order, not to replace the formal entry calculation.

For the busiest import lanes, yes. This hub calculator handles any origin you select, but we also publish dedicated pages pre-set with the measures that matter for that country, including China to US, Mexico to US, Vietnam to US, and EU to US, alongside Canada to US, Japan to US, South Korea to US, Taiwan to US, India to US, Thailand to US, Malaysia to US, Indonesia to US, and Brazil to US, with more lanes added over time. The country versions start on the right origin and highlight the layers most likely to apply, so you spend less time configuring and more time reading the result. Under the hood they share the same rate logic as this hub, so the numbers stay consistent whichever entry point you use. If your origin does not have its own page yet, use this general calculator and simply select the country from the origin field to get the same layered estimate.

More often than most importers expect. The base rate in the Harmonized Tariff Schedule is relatively stable, but the trade-policy layers move constantly: Section 301 lists are revised through review cycles and exclusion processes, Section 232 and IEEPA measures are added, paused, or adjusted with limited notice, and the Section 122 baseline can shift with policy. A duty figure that was correct one quarter can be stale the next. That is why the calculator is kept aligned to the current schedules and why we pair it with a tariff tracker that watches the specific HTS codes and origins you import and alerts you when a rate on one of them moves. Relying on a number you looked up months ago is one of the most common ways importers get caught by a higher bill.

It includes them where they apply. Beyond the base rate, some products carry Section 232 duties, which cover certain steel and aluminum goods, and some origins carry IEEPA-based tariffs tied to specific policy actions. These layers can stack on the same shipment, so a product can owe the base rate, a Section 301 add-on, and a 232 or IEEPA duty at once. The calculator identifies when your HTS code and origin may fall under one of these programs and includes it in the estimate where the rate is clear. Because these measures shift with policy and can involve product-specific scope questions, they are also the situations where a broker review is most valuable. If your product touches steel, aluminum, or a recently announced measure, confirm the layers before you rely on the total.

Because on many imports the base rate is only the first layer. The most-favored-nation base rate tied to your HTS code is what every origin pays under normal trade relations, and for many products it is low or even free. The trade-policy measures then stack on top: a Section 301 add-on of 7.5% to 25% on Chinese goods, Section 232 duties on steel and aluminum, IEEPA rates on some origins, and the Section 122 baseline where in force. So a code with a 3% base rate can carry a 25% add-on for a combined 28%. This is exactly why a duty estimate built only on the base rate is misleading. The calculator combines all applicable layers against your customs value so the total reflects what you will actually owe, not just the smallest component of it.

Yes, and that is one of its most useful jobs. Enter the same HTS code with different countries of origin and you can see how the duty changes, since Section 301 applies only to Chinese goods, Section 232 and IEEPA vary by origin, and a free trade agreement can zero out the base rate for a qualifying country. That comparison often reshapes a sourcing decision. For structured side-by-side scenarios across several codes and origins at once, the tariff simulator is built for that deeper modeling, while this calculator is focused on a fast estimate per origin. Either way, remember that duty is one component of landed cost alongside freight, lead time, and quality, so use the number as one input into the sourcing decision rather than the whole answer.

Start from what the product actually is, its material, function, and construction, because those drive where it sits in the Harmonized Tariff Schedule. You can search the schedule by description to narrow to a chapter and heading, then work down to the full 10-digit code. The difficulty is that many products can plausibly fit more than one heading, and the wrong choice changes both your base rate and your trade-policy exposure. The calculator lets you search by description to help, but for anything ambiguous, a component-heavy product, a novel item, or a set, have a licensed broker confirm the classification. Because duty accuracy rides entirely on the code, a short classification review up front is far cheaper than an entry correction or a penalty discovered after the goods have already shipped.

The calculator is free to use on your own and is a genuine help for early planning, but a formal United States import entry is filed by a licensed customs broker or a qualified self-filer, and the broker is who verifies the classification, value, and origin the estimate depends on. In practice most importers use the calculator to screen a decision quickly, then bring in a broker to confirm the HTS code, the customs value, the country of origin, and any additional duty layers before the entry is filed. That is especially true for high-value shipments or uncertain classifications, where a wrong self-estimate is expensive. Because our brokerage sits inside CargoTrans, the estimate you run here and the entry we file are handled by the same team, so there is no handoff gap between the number and the filing.

Yes. Duty is the largest and most variable charge, but it is not the only one. Federal fees include the merchandise processing fee and, for ocean shipments, the harbor maintenance fee, both assessed on your entry. On top of that sit customs brokerage fees, international and domestic freight, insurance, and any warehousing or handling at destination. The calculator focuses on the duty layers, base rate, Section 301, 232, IEEPA, Section 122, and AD/CVD, because those are what vary most by product and origin. To build a true landed cost, add the federal fees and your logistics charges to the duty estimate. Our team can help you assemble the full landed-cost picture so a sourcing decision reflects everything you will actually pay, not just the tariff line.

The calculator is designed as a quick, no-login tool, so you can run an HTS code, customs value, and origin and see the duty without creating an account. It is meant for fast estimates rather than record-keeping, so we recommend saving or exporting any result you want to keep into your own landed-cost model. If you want your recurring codes monitored for rate changes, or a broker to review your classification and confirm the duty, that is where you would set up an account with our team and connect to the tariff tracker. For a one-off estimate, though, you can use the calculator freely and anonymously, then reach out only if you want the number verified or watched over time.
