Use this free import duty calculator to estimate what a shipment will really cost to bring into the United States: base duty from the HTS code, Section 301 and Section 232 tariffs, the Merchandise Processing Fee (MPF), the Harbor Maintenance Fee (HMF), and your margin per unit. Compare up to three countries of origin side by side before you place the PO.
Built and maintained by Argents Express Group, a licensed US customs broker and CTPAT-validated partner to importers since 1977. Rates change often. When the numbers matter, talk to a broker before you book.

Enter what you are importing and pick an HTS code (or type one in), the country of origin, units, cost per unit, sale price and freight. The calculator then stacks every charge that applies at entry:
| Charge | What it is | How it is calculated |
|---|---|---|
| Base duty | The general (MFN) rate in the Harmonized Tariff Schedule | Usually a percentage of customs value (ad valorem); some goods use a per-unit or compound rate |
| Section 301 tariffs | Additional duties on many goods of Chinese origin | Added on top of base duty, at a rate set by the list the HTS code falls on |
| Section 232 tariffs | National security tariffs on steel, aluminum and certain derivative products | Applied to the covered value of those products |
| Merchandise Processing Fee (MPF) | CBP processing fee on formal entries | 0.3464% of entered value, with a minimum and maximum CBP adjusts each fiscal year |
| Harbor Maintenance Fee (HMF) | Fee on cargo arriving at US seaports | 0.125% of cargo value, ocean shipments only |
| Landed cost per unit | Everything above plus product cost and freight | Total divided by units, compared against your sale price to show margin |
Shipping into the EU instead? Switch the destination and the calculator adds EU duty, import VAT and the new per-parcel fee for low-value e-commerce shipments.
If you want to check the math yourself, US import duty follows a simple order:
Example: 1,000 units at $5.00 from China, with a 16.5% base rate and a 25% Section 301 tariff. Customs value $5,000. Base duty $825. Section 301 $1,250. MPF and HMF add more on top. Duty alone has raised the unit cost from $5.00 to more than $7.00 before freight. That is why country of origin comparisons matter.
Any duty or tariff calculator is an estimate. Your entry can come out different because of:
Argents handles the whole trip after the calculator: freight forwarding, customs brokerage, warehousing and e-commerce fulfillment out of Argents-operated facilities in Chicago, Seattle and Charleston, SC. One team files your entry, receives your container and ships your orders, so the duty you planned for is the duty you pay.

Yes. There is no login. After a few calculations it asks for an email so a broker can follow up if you want help.
Start typing your product into the calculator and it suggests matching HTS codes. For anything high-value or ambiguous, have a licensed customs broker confirm the classification before you ship.
In everyday use they mean the same thing: a tax on imported goods. “Duty” usually refers to the base HTS rate, and “tariff” is often used for added measures like Section 301 or Section 232.
The importer of record pays duty to CBP, usually through their customs broker. Under DDP terms the seller takes on that role and cost.
No. Import duty is one piece. Landed cost adds product cost, freight, insurance, CBP fees, brokerage and inland delivery. This calculator shows both.
The calculator draws on a live tariff database, but tariff actions can take effect quickly. Treat results as a planning estimate and confirm with a broker before committing to a purchase order.
