Before you rely on this estimate
  • Confirm HS/HTS classification with official sources or qualified professional advice.
  • Check whether preferential rates, anti-dumping/countervailing duties, quotas, exclusions, or exemptions apply.
  • Confirm whether freight and insurance belong in the customs value for your destination and Incoterms.
  • Verify the correct import-tax base before filing or collecting duties from a buyer.

TariffsChart is a planning tool only. It is not an official customs database, tax advisor, attorney, freight forwarder, or government authority. Results are estimates based on user-entered assumptions and must be verified with official sources and qualified professionals before filing, buying inventory, quoting customers, or making binding decisions.

How this import duty calculator works

Use the calculator for planning before a purchase order or margin quote. It does not replace official classification, Chapter 99 review, AD/CVD checks, or qualified professional advice.

How to calculate landed cost

Start with the customs value, add base import duty, additional tariff layers, import taxes, fixed fees, freight, and insurance. The calculator separates dutiable value from cash-flow landed cost so you can see both the filing assumption and the margin impact.

Import duty formula

A basic planning formula is: customs value × duty rate = base duty. For a real shipment, review the HTS code, origin, Chapter 99 instructions, Section 301 or Section 232 layers, AD/CVD, quota, and valuation basis before relying on the result.

FOB vs CIF landed cost

FOB or EXW quotes usually require adding freight and insurance to model cash outlay. CIF quotes already include freight and insurance in the supplier price. Customs valuation rules vary, so confirm whether those logistics costs belong in the dutiable value for your route.

China to US tariff calculator

For China-origin goods, enter the HTS code, base MFN rate, any Section 301 layer, possible Section 232 exposure, and source notes. Then confirm Chapter 99 and exclusion treatment with official sources or qualified professional advice.

Amazon seller import duty calculator

Marketplace sellers can model landed cost per unit before setting a target price. Include duty, tariff layers, logistics, fixed fees, and target margin so the product decision is based on landed cost rather than supplier cost alone.

Calculation boundary

US import planning starts with invoice value, HS/HTS code, origin, destination, a source-backed MFN base field, explicitly entered additional-duty assumptions, freight, insurance, taxes, and fixed fees. Unknown policy layers are neither treated as zero nor added into an unsupported final rate.

Resolve policy layers before adding logistics and margin

The duty-stack resolver separates base MFN, forced-labor Section 301, the Section 232 carve-out, Annex scope, AD/CVD, and other review items. Carry the known rate back here, then add freight, insurance, fees, and target margin.

Example

Cotton T-shirt from China: start with MFN, then review Section 301 and Chapter 99 separately.

Example

Lithium battery from Vietnam: compare base duty, logistics, margin, and unresolved origin-policy questions.

Example

Steel pipe from Mexico: confirm USMCA eligibility, then review Section 232 and AD/CVD scope.

Calculation method

FOB/EXW mode does not silently add international freight and insurance to the US duty base; those costs enter landed cash cost once. CIF mode subtracts separately stated freight and insurance from an invoice that already includes them to form a planning US customs value. Final valuation still depends on supporting documents and qualified review.

Unresolved layers

A base HTS field is not a final filing rate. Chapter 99, Section 301, Section 232, AD/CVD, quotas, exclusions, preference programs, and entry date can still change the result.
