  • Illustrative arithmetic, not a tariff quote or entry-eligibility check. No automatic low-value exemption is applied.
  • Only add rates that apply additively to the same customs value. Simple additive compound duties are supported with confirmed bases and units. Alternative, minimum/maximum and other conditional duties need separate calculation. Include each fee once.
  • Illustrative scenario — replace with confirmed HTS rates and fees

Last checked 2026-11-14. Rules change, sometimes at short notice. We list the date we last checked each official source; confirm with the official government source before you travel, buy or file. This is general information, not legal or immigration advice.

This is a general estimate for information only, not tax, legal or financial advice. Real rules have more conditions than a calculator can show, so check the official source below or a qualified professional for your situation.

How it works

This tool performs arithmetic for a scenario you supply. Ad valorem duty uses confirmed customs value; specific duty uses the quantity and unit stated in the tariff. Customs value may differ from the purchase cost. Confirm valuation, origin, classification, entry date and transport process with official guidance.

duty = customs value × combined applicable percentage ÷ 100 + quantity × specific duty per unit landed cost = goods cost + shipping/insurance + duty + government fees + carrier/broker charges

Add percentage rates only when each applies additively to the same value. Simple additive compound duties are supported when the bases and units are confirmed. Alternative, minimum/maximum and other conditional duty formulas are excluded. Government fees, commercial fees and any exchange conversion are your inputs; all amounts must already be in USD.

CBP’s July 2026 mail guidance describes the suspended low-value exemption and replacement postal process. This calculator never assumes that a low-value parcel is exempt, nor checks whether it qualifies for a postal entry process or another exclusion. It does not select HTS codes or supply live tariff rates.

Rounding: no intermediate rounding; displayed money is rounded to two decimal places.

Before entering rates: identify the product classification in the official HTS; confirm country of origin and entry date; check additional tariffs, units, valuation and government entry fees. The USITC tariff database provides tariff-line data. CBP determines the applicable treatment. Select percentage-only, specific-only or combined duty as appropriate.

Worked examples

Illustrative $500 goods shipment

With customs value $500, a user-entered 10% rate, $40 shipping and $15 carrier charge, duty is $50 and landed cost is $605.

Illustrative additive compound duty

Goods and customs value $200, shipping $20, rate 5%, quantity 4 and $2 specific duty per unit, plus $3 government fees and no carrier fee: duty is $18 and landed cost is $241.

Frequently asked questions

Does a parcel under $800 automatically have no duty?
No exemption is assumed here. Check current CBP guidance and the particular shipment’s treatment.
Where do I get the duty rate?
Start with the official HTS and USITC tariff database. Confirm classification, origin, entry date, additional duties and units against CBP guidance; CBP makes the final determination.
Can I use the example 10% for my shipment?
No. It is an arithmetic example with no country or product meaning. Replace every rate and fee with confirmed values.
Why are purchase cost and customs value separate?
The landed-cost total uses what you pay; the duty formula uses the confirmed valuation basis. This avoids silently treating all transport costs as dutiable.
Are sales tax and every possible charge included?
Only the entered costs are included. Add confirmed applicable government charges to the fee input without double counting. This is not a comprehensive tax assessment.
