Import duty calculator — the real total, layer by layer

Most calculators stop at the headline rate. From China, the headline rate is often the smallest part. This one adds every Chapter 99 layer that actually applies — Section 301, Section 232, the forced-labor surtax — plus customs fees, and shows its work.

What gets added up: the import duties plus the MPF and HMF customs fees. Freight and insurance are not included — the result is what you owe Customs, before shipping costs. To add freight and insurance and see the full landed cost, use the Landed Cost Calculator — same duty math, one more step.

1 · Product or code
2 · Where it is from
3 · Value, date & shipping
4 · Result + what to check

Step 1 · What are you importing?Type the 8–10 digit HTS code from your shipping paperwork. HTS code

Enter the product code your goods are classified under — 8 to 10 digits, from chapters 1–97 of the tariff schedule. Codes starting with 99 are Chapter 99 add-on lines: extra duties (Section 301 / 232) or temporary suspensions that sit on top of a product code, so they can't be calculated on their own. If your paperwork shows a 9902… line, enter the product code named in its description instead.

Don't know the code? Find it by product name first — guessing a code is how shipments get reclassified.

Step 2 · Where is it from?The country where the goods were made. Country of origin

Origin means where the goods were made, not where they ship from.

Step 3 · Value, date & shippingWhat the goods are worth, when they arrive, and how they ship. Customs value (USD) Entry date Shipping Quantity (only if the duty is charged by weight or piece)
