US Customs and Duties Calculator - Exact-Match Variant
Answer: US customs and duties are estimated as customs value times the confirmed duty rate, plus additional tariffs, MPF, ocean HMF, and broker or clearance fees; use /tools/u-s-customs-duty-calculator/ as the canonical calculator.
- Estimate only: confirm HTS classification, country of origin, trade-remedy tariffs, and entry treatment with live HTS/CBP data or a licensed customs broker.
- Additional tariffs are calculated as a separate ad valorem line on customs value; confirm whether Section 301, 232, AD/CVD, or other measures apply.
US customs and duties are estimated as customs value x confirmed duty rate, plus any additional tariffs, Merchandise Processing Fee (MPF), Harbor Maintenance Fee (HMF) for ocean imports, and broker or clearance fees.
How the calculation works
This page is an exact-match keyword variant for the search phrase “US customs and duties calculator.” The canonical broader calculator is the U.S. customs duty calculator. Use that canonical page for internal linking, broader customs-duty intent, and general U.S. import-duty planning.
The calculator uses the same conservative model as the canonical page. It does not classify the product, choose an HTS code, determine country of origin, or provide legal advice. Before importing, confirm the live Harmonized Tariff Schedule, CBP entry rules, trade-remedy tariffs, and broker interpretation.
| Line item | Formula used in this estimator |
|---|---|
| Base customs duty | customs value x base duty rate |
| Additional tariffs | customs value x additional tariff rate |
| Formal-entry MPF | customs value x 0.3464%, subject to FY2026 minimum and maximum |
| Informal-entry MPF | Automated informal-entry fee estimate |
| Ocean HMF | customs value x 0.125% |
| Estimated total import charges | base duty + additional tariffs + MPF + HMF + broker fee |
For post-2025 commercial import planning, do not use duty-free Section 321 as the default assumption. This calculator keeps the estimate conservative by requiring duty, tariff, MPF, HMF, and broker-fee assumptions to be tested directly.
FAQ
Is this the canonical US customs duty calculator?
No. This page targets the exact keyword “US customs and duties calculator.” The canonical broader calculator is the U.S. customs duty calculator.
What does this calculator estimate?
It estimates base customs duty, additional tariffs, MPF, HMF for ocean imports, optional broker or clearance fees, and a total import-charge planning amount from the customs value and rates you enter.
What value should I enter as customs value?
Use the entered or appraised merchandise value used for U.S. customs purposes. For many commercial shipments this starts with the transaction value of the goods, but assists, royalties, related-party pricing, packing costs, and valuation adjustments can change the correct value.
How do I find the duty rate?
Find the product’s HTS code in the current U.S. Harmonized Tariff Schedule, then review the General, Special, and Column 2 rates plus chapter notes and tariff actions. If classification is uncertain, request broker review or a binding ruling before relying on the rate.
Does this include Section 301 or Section 232 tariffs?
Yes, if you enter the additional tariff rate. The calculator keeps additional tariffs separate from base duty because Section 301, Section 232, AD/CVD, and other measures can apply independently from the base HTS rate.
Does this model duty-free Section 321?
No. For current commercial import planning, do not assume duty-free de minimis treatment as a normal e-commerce path. Narrow statutory exemptions may require broker review, but this calculator does not model them as duty-free Section 321 clearance.
What are MPF and HMF?
MPF is the Merchandise Processing Fee collected on many U.S. customs entries. HMF is the Harbor Maintenance Fee for many ocean imports. Both are government fee lines, separate from base duty and separate from broker service charges.
Why do I still need broker review?
The final amount depends on classification, country of origin, customs value, entry type, trade remedies, exclusions, partner-government-agency flags, and CBP liquidation. A calculator can support planning, but it cannot replace shipment-specific compliance review.

Dated facts
As of May 13, 2026, use these facts as planning assumptions only and verify them against live official sources before import:
- This page is an exact-match keyword variant for “US customs and duties calculator”; the canonical broader page is
/tools/u-s-customs-duty-calculator/. - FY2026 formal-entry MPF is modeled at 0.3464% of customs value with a $33.58 minimum and $651.50 maximum, effective for the fiscal year that began October 1, 2025.
- HMF is modeled at 0.125% of value for ocean imports. The calculator does not apply HMF to air, truck, rail, or mail shipments.
- CBP’s post-2025 de minimis enforcement environment makes duty-free Section 321 unsuitable as a default commercial planning assumption in this estimator.
- Many China-origin products remain exposed to additional Section 301 tariffs, often 7.5% or 25% depending on the HTS code and current exclusion status; confirm the live rate before quoting.
- CBP can review or liquidate entries after release, so the paid-at-entry amount can still change if classification, value, origin, or duty treatment changes.
