Use the result to compare options early, then confirm the final commercial and regulatory details with the right provider before you commit.
When to Use This Calculator
- Before placing an order to estimate likely duty and tax exposure.
- When comparing classification, origin, or exclusion scenarios.

Frequently Asked Questions
How accurate is this calculator?
This calculator provides a planning estimate based on published duty logic and your inputs. Final liability still depends on classification, origin, exclusions, valuation, and customs treatment.
What can make the real-world result different?
Classification changes, origin rules, exclusions, broker interpretation, and customs review can all change the final result.
How often are rates in this calculator updated?
We update calculator pages when underlying assumptions or published inputs change. The last review date is shown in the calculator header, but you should still verify live quotes, official schedules, and provider-specific fees before acting.
What should I verify before acting on the result?
Verify the classification, origin treatment, and filing assumptions with the official tariff database or a licensed customs professional before relying on the result.
Tips for China Importers
- Look up your HS code first. Your HTS/HS code determines your duty rate. Use hts.usitc.gov (US), trade.gov.uk/tariff (UK), or cbsa-asfc.gc.ca (Canada) — not your supplier's guess.
- Check for Section 301 exemptions. Some products have granted exclusions at ustr.gov. These can eliminate the additional 7.5–25% tariff entirely. Verify before every order.
- First Sale Valuation can lower your duty base. If buying through a trading company, CBP may allow you to declare the factory price (not the middleman price) as the dutiable value — ask your customs broker.
- Get a Binding Ruling for anything uncertain. CBP can issue a written classification ruling at no charge through its binding-ruling process. It can help when your product classification is unclear.
- Keep import records for 5 years. CBP can audit any entry up to 5 years post-import. Store your commercial invoices, packing lists, and entry summaries.
