Does the calculator include Section 301 tariffs?

It adds a Section 301 estimate for China-origin goods only when the official HTS line explicitly references a supported Chapter 99 heading with a deterministic ad valorem rate.

Does the calculator include Section 232 steel tariffs?

Only for the locked Phase 25 family: China-origin goods under complete 10-digit primary-steel HTS lines matching the reviewed Annex I-A scope, using 9903.82.02 at 50% of full customs value. Other Section 232 cases require review.

What data does TariffCalc use?

The calculator uses a versioned USITC HTS publication and source-backed CBP fee rules. The current data version and checksum are shown on the data status page.

Calculate US import duty by HTS code.

Q: Does the result include every US tariff?

No. Section 232 outside the locked China-origin primary-steel Annex I-A family, Section 122, AD/CVD, quotas, safeguards, excise, preferences, and product-specific exclusions remain outside automatic coverage.

Q: When are MPF and HMF included?

Formal-entry MPF is included only when formal entry is selected. HMF is included only for ocean transport when the user confirms covered commercial-vessel cargo at a subject US port.

See the general duty, formal-entry MPF, ocean HMF and supported Section 301 China tariff and a locked China-origin primary-steel Section 232 beta with explicit fee assumptions, formulas, effective dates and sources.

US tariff calculator FAQ

What this estimate covers

Does it include Section 301?

Yes, for China-origin goods when the selected HTS line explicitly references a supported Chapter 99 Section 301 heading. The result shows the heading, rate, amount and source.

Does it include Section 232?

Only for China-origin goods under a complete 10-digit HTS code beginning 7208. That source-backed beta uses 9903.82.02 at 50% of full customs value. Its source and arithmetic fixtures have passed internal validation; no external customs-professional approval is claimed.

Does it include every US tariff?

No. Other Section 232 products or origins, Section 122, AD/CVD, quotas, safeguards, excise, preferences and product-specific exclusions may require facts that this beta does not collect.

Where do the HTS rates come from?

The tariff schedule is a versioned USITC publication. Visit the data status page for the exact release, effective date and checksum.

When are MPF and HMF included?

Formal-entry MPF is added only when you select formal entry. HMF is added only for ocean transport when you confirm covered commercial-vessel cargo at a subject US port. Unknown fee facts produce a review-required estimate and are not silently charged.
