Import Duty From China to USA Calculator

China-to-USA duty is a stacked calculation

For China-origin goods, import duty is rarely just the base HTS rate. Many products also face Section 301 additional duties, and every formal entry can include MPF. Ocean shipments may add HMF.

Use the TariffCheck calculator to estimate the full stack for your product and shipment value.

Use this page when the search question is specific

This page is for importer searches like:

• "import duty from China to USA calculator"
• "how much is customs duty from China"
• "China tariff calculator with Section 301"
• "landed cost from China to USA per unit"
• "does MPF apply to China imports"

If your question is broader than China, start with the US tariff calculator. If your shipment is ocean cargo, calculate MPF and HMF separately because those fees can change the per-unit cost on low-margin goods.

China import duty checklist

Step	Why it matters
Find the HTS code	Determines the base duty rate
Confirm China origin	Section 301 follows origin, not shipping route
Check Section 301	Adds a China-specific duty layer where applicable
Add MPF	Common formal-entry CBP fee
Add HMF	Applies to covered ocean cargo
Add freight and broker cost	Needed for landed cost

Example structure

A $10,000 China-origin shipment might have:

• Base HTS duty
• Section 301 additional duty
• MPF
• HMF if ocean cargo
• Broker, bond, and delivery costs

The exact rate depends on the product classification. Do not use one flat China tariff percentage for every product.

Does shipping through another country avoid China tariffs?

Usually no. US customs duty follows country of origin. Routing Chinese-origin goods through another country does not remove Section 301 unless substantial transformation changes origin.
