How this USA tariff calculator works

This page is a practical import duty calculator for U.S. entries. You provide an HTS code, country of origin, customs value, transport mode, and quantity. The tool calls a live tariff API and displays estimated duty, Merchandise Processing Fee (MPF), Harbor Maintenance Fee (HMF when applicable), and a simple landed-cost total.

What you enter

  • HTS code — preferably 8–10 digits (periods optional). Wrong classification = wrong duty.
  • Country of origin — drives which additional measures the data source may stack.
  • Customs value (USD) — dutiable value used for ad valorem math and fees.
  • Transport mode — ocean may include HMF; air/truck/rail typically do not.
  • Quantity — passed through when the API expects unit counts.

What the results mean

  • Applicable rate / total duty — combined duty amount returned by the API after base and additional components.
  • MPF — CBP merchandise processing fee estimate.
  • HMF — harbor maintenance fee estimate (vessel/ocean oriented).
  • Landed cost — value + duty + MPF + HMF (freight/insurance not included unless you add them yourself).
  • Component list — line items when the API returns a tariff breakdown.

How to run a calculation

  1. Paste your best HTS code.
  2. Select origin and enter shipment value in USD.
  3. Choose transport mode.
  4. Click Calculate Duty and wait for the live response.
  5. Read the duty and fee cards; expand the component list for stacking detail.

Limits (read before relying on a number)

This is not a binding CBP ruling. Antidumping/countervailing duties, quotas, excise, and some product-specific notes may be incomplete. Free Trade Agreement claims often need documentation your broker manages. Always verify classification and rates with a licensed customs broker and official sources such as the USITC HTS.
