Estimate import duty, additional tariffs, freight, insurance, fees, unit cost, and target price before you order inventory.
Answer
A US import duty estimate starts with HS/HTS code, origin, destination, customs value, base duty rate, additional tariff assumptions, freight, insurance, and fixed fees. The result is a planning estimate, not a final customs filing rate.

Cotton T-shirt from China: model MFN + Section 301 assumptions.

A high-intent lane template with the official source checklist importers usually need before broker review. Rates remain user-entered until confirmed.
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.
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.
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.
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 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.
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.
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.
The calculator adds base duty, additional tariff assumptions, tax, freight, insurance, and fees to estimate landed cost. Simple mode applies default logistics assumptions until you customize advanced fields.
It does not replace official HTS classification, customs valuation, AD/CVD review, Chapter 99 instructions, or qualified professional advice before filing.
