Tariff lookup
US tariff rate lookup: MFN base by product or US HS/HTS
Enter a product name or known US HS/HTS code to continue in the unified workbench. This page explains how to read MFN rates, additional duties and the conditions needed for an estimate. If you only have a China HS8/HS10 line, enter it in the same workbench and confirm China as its source.
What is a US tariff lookup?
A US tariff lookup starts with the applicable HTS classification and its MFN base rate. Additional duties require separate origin, date and product facts. Results depend on the exact HTS classification — the same product can carry different rates depending on material, use, or construction; continue in the same workbench to review possible additional duties and estimate amounts using the origin and product facts. Enter a China HS8/HS10 line in the same workbench and confirm its source.
How it works
- Enter a product name or known US HS/HTS code. If you have a China HS8/HS10 line, start with the China-to-US crosswalk.
- Confirm a matching US HTS candidate in the workbench, then supply origin to check current rules.
- Open HTS detail or the duty calculator to review possible additional duties and estimate total duty based on the origin and product facts.
FAQ
How do I look up the tariff for goods exported from China to the US?
If you only have a China HS8/HS10 line, enter it in the same workbench to find US HTS candidates under the verified shared HS6. Continue in the same workbench using the origin and product facts; add a customs value only when an amount is needed.
What makes up the total US tariff rate?
This page explains the parts of a tariff rate. After confirming the US HTS classification, use the workbench to review possible additional duties and estimate total duty based on the origin and product facts.
Does the rate shown here include Section 301?
The MFN base rate excludes additional duties. Use the workbench with the origin and product facts under current rules to review possible additional duties and estimate total duty.
I only have a China HS code, not a US HTS code — what do I do?
Enter the China HS8/HS10 line in the unified workbench and confirm its source; it checks the China code before finding US candidates under the shared HS6.
