What this tool does

The ETDETA Import Duty Calculator estimates what a U.S. import will cost in duties and total landed cost. You enter an HTS code (or search for one), the country of origin, the goods value, the transport mode and the entry date, and it returns an estimated base (MFN) duty, any Section 301 or other Chapter 99 tariff layers that may apply, the Merchandise Processing Fee (MPF), the Harbor Maintenance Fee (HMF, ocean shipments only), and a reference landed cost.

It is built for planning and budgeting — pricing a product, quoting a customer, or comparing sourcing options — so every figure is framed as an estimate. Duty on U.S. imports is driven by the tariff classification, the customs value and the country of origin, plus any additional Chapter 99 measures in effect on the entry date, so the calculator makes those inputs explicit and shows the rate stack layer by layer rather than a single opaque number.

Who should use it

Importers, buyers and finance teams pricing a product or a purchase order, sourcing teams comparing the delivered cost of different origins, and 3PLs/forwarders giving clients a quick duty estimate before a formal customs-broker review.

What data it checks

Public HTSUS / USITC base (MFN) duty rates for the entered HTS code.
Chapter 99 (9903) tariff-layer references — Section 301, Section 232, IEEPA-related measures.
The current CBP Merchandise Processing Fee (MPF) min/max for the entry's fiscal year, and the Harbor Maintenance Fee (HMF) rate for ocean shipments.

How to use it

Enter or look up the product's HTS code.
Set the country of origin, the entered goods value, the transport mode and the entry date.
Review the estimated base duty, the Chapter 99 / Section 301 layers, MPF, HMF and landed cost.
Confirm the applicable rates, layers and any exclusions with a licensed customs broker before you file or commit.

What the results mean

An estimated combined duty rate and estimated duties for the entered value.
A rate stack: the base HTS line plus any Chapter 99 / Section 301 layers, each labeled.
Estimated MPF and HMF, and an estimated landed cost (goods value + duties + fees).

What this tool does not determine

It is an estimate based on user-entered data and tariff references — not a final duty determination or a CBP assessment.
Chapter 99 / Section 301 applicability and exclusions are fact-specific and change over time; verify the current status for your entry date.
Final duties, classification, customs value and origin must be confirmed with a licensed customs broker, trade counsel, and/or CBP.

FAQ

Is this a final U.S. customs duty calculation?

No. It is an estimate based on user-entered data and tariff references. Final duties, classification, value, origin, Chapter 99 applicability and filing decisions must be confirmed with a licensed customs broker, trade counsel, and/or CBP.

Does the calculator include Section 301 tariffs?

It can show selected or current tariff layers where available, including Section 301 or other Chapter 99 layers. Applicability and current exclusions must be confirmed before filing.

Does it calculate MPF and HMF?

Yes — it estimates the Merchandise Processing Fee (MPF, within its statutory min/max for the entry's fiscal year) and the Harbor Maintenance Fee (HMF, 0.125%, ocean shipments).

Does this replace a customs broker?

No. It is a planning tool, not customs-broker advice or a filing instruction.

Why might my actual duty differ from the estimate?

Actual duty depends on the final classification, the transaction value and valuation rules, the confirmed origin, and the Chapter 99 layers and exclusions in effect on the entry date.

Can I compare duty across countries of origin?

Yes — use the Compare Sourcing Countries tool to put origins side by side for the same product.
