Import duty from China calculator with tariff checks

Planning Use only. Broker review required for Entry Use.

An import duty from China calculator should not start with country alone. China origin matters, but the duty stack still depends on the HTS candidate, customs value, Section 301 treatment, exclusions, fees, and whether the supplier facts are strong enough for review.

Use this page to keep the calculator answer tied to evidence instead of a loose estimate.

quick answer

For "import duty from China calculator", collect the product facts, supplier code, HTS candidate, China origin support, invoice value, quantity, assists, freight, insurance, shipment timing, and Section 301 check. Calculate only for Planning Use until a broker or customs authority reviews the Entry Use path.

Do not assume every China-origin product has the same tariff exposure.

facts to collect for a China duty estimate

Collect:

Product name, SKU, model, photos, labels, specs, bill of materials, and commercial use.
Supplier HS or HTS code and the source of that code.
HTS candidate families and why each one fits or does not fit.
China origin evidence, including manufacturing steps, final assembly, and any non-China inputs.
Invoice value, currency, quantity, assists, royalties, freight, insurance, Incoterms, and planned entry date.
Base duty, Section 301 question, exclusion claim if any, AD/CVD flags, and fees.
Authority sources checked and date checked.
Missing Facts and broker review status.

Keep the calculator math and the product evidence together.

missing facts

Mark the file incomplete when:

The product description is too broad for classification.
Origin is based only on the supplier address.
HTS candidate support has not been checked in official sources.
Section 301 treatment is assumed from a blog, calculator, or old quote.
Value additions outside the invoice are unknown.
Exclusion claims lack a source date.
Broker review has not happened for Entry Use.

These gaps can change the duty estimate even when the calculator formula is right.

HTS candidate notes

Build candidate rows for the product first. Each row should show base duty, China-origin treatment, Section 301 status, value assumptions, source checked, and Missing Facts. If the supplier code is only six digits, use it as a lead and write that limitation into the row.

Rejected candidates matter because they explain why the estimate moved.

authority sources

Use USITC HTS for duty text. Use CBP CROSS for classification support. Use USTR for Section 301 material. Use CBP guidance and 19 CFR 177.2 when ruling support is needed.

planning path

Start with a shipment snapshot: product, origin, value, and timing. Then calculate base duty and extra duty for each supported HTS candidate.

The output should say what was checked and what is still missing. That makes it usable before sourcing, purchase order approval, or broker review.

If the supplier changes factories, repeat the origin check before reusing the estimate.

questions importers ask

Is China origin enough to calculate duty?

No. Origin is one input. HTS candidate and value still control the estimate.

Can a calculator be used without broker review?

No. Use it for Planning Use and route the file to review before filing.

planning boundary

This import duty from China calculator page is a planning artifact. It is not an Entry Use classification, not a binding ruling, and not a legal opinion. The importer remains responsible for reasonable care and must obtain broker or customs authority review before filing.
