Answer Summary

What this page answers

Question

How do I estimate import duty for an international shipment?

Automatic mode sends the HTS code, origin, destination, entry date, and customs value to TariffCatalog's canonical resolver, then keeps government charges separate from tax and commercial service fees. Manual mode remains available for source-checked rates.

Formula / Criteria

What to check

Total import cost = customs value + base duty + additional tariff + VAT or tax + brokerage + handling + other fees. The tax basis can be customs value only, customs value plus duty, or customs value plus duty plus additional tariff.

Use This Tool

When to use it

Use source-backed automatic tariff resolution when HTS, origin, destination, and entry date are known. Use Manual mode only as an explicit fallback with rates you have verified.

Official Source Note

Source-check required

Use official tariff databases to verify the base duty rate. Use the additional tariff field for Section 301-style scenarios when applicable.

FAQ

Common questions

Is this also a tariff calculator?

Yes. Tariff, import duty, customs duty, and duty charge searches often refer to the same product-specific border-cost calculation. This tool keeps base duty, additional tariffs, tax, and non-duty fees separate.

How much import duty do I pay from China to USA?

It depends on HTS code, customs value, origin, and applicable additional tariffs. Use base duty plus additional tariff fields instead of assuming a universal rate.

Is my product subject to Section 301 tariff?

Check the HTS code and applicable USTR/USITC references. Use the additional tariff input when a verified product-and-origin-specific additional duty applies.

Does VAT apply to duty?

In many VAT systems, import VAT is calculated on customs value plus duty. Verify destination-specific rules.

What is customs value?

Customs value is the value used by customs to assess duty. It may be FOB, CIF, or another basis depending on destination rules.

Are estimates guaranteed?

No. They are planning estimates only.
