Goods Freight and insurance Duty and taxes
This is an estimate, not a customs assessment. It excludes broker fees, port and terminal charges, inland transport and product certification. Rates change, and the final amount depends on the classification and value accepted by customs.
How it is calculated in United States
US duty is calculated on the transaction value, which normally excludes international freight and insurance.
Tariffs on Chinese goods changed several times in 2025 and 2026. Enter the current additional rate for your HTS code in the second field. We do not pre-fill it because it moves too often.
The MPF has a minimum and maximum per entry that are adjusted every year, so small and very large shipments can differ from this estimate. There is no federal VAT, but state sales tax may apply when you sell.
