US import tariff calculator FAQ
What does this US import tariff calculator include?
It estimates HTS-based duty, China Section 301 tariffs, common customs fees such as MPF and HMF, and total landed cost from the product, origin, and value you enter.
Can I use the calculator before I know my HTS code?
Yes. TariffCheck can start from a plain-English product description, suggest a likely HTS classification, and then calculate the duty stack from that classification.
Is this a replacement for a licensed customs broker?
No. Use it for sourcing, pricing, and feasibility estimates. For final customs entry, binding classification, or complex products, confirm the result with a licensed customs broker or official CBP guidance.
Which origins can I check?
The calculator supports US imports from any country. It is especially useful for China-origin goods because Section 301 tariffs can materially change landed cost.
