International freight ($)

Cargo insurance ($)

Customs valuation basis

Duty rate for the tariff code (%)The ad valorem rate for your HS/HTS code and country of origin

Additional tariffs (%)Only add rates confirmed to apply cumulatively to the same customs value. Exclusions, content-based duties and trade-remedy calculations are not inferred.

Quantity of units

Specific duty per unit (optional) ($ per unit)

Import VAT / GST (%)Enter the applicable product and destination rate, including any exemption.

VAT / GST is charged on

Additional amount included only in the VAT base ($)Taxable incidental costs already included in fees below, such as onward delivery. Avoid counting any amount twice.

Uncapped fees as % of customs value (%)No minimum, maximum or exemptions are applied. Put a separately calculated capped fee in flat fees instead.

Flat fees (broker, bond, handling) ($)

The duty on an import is a percentage of its customs value, set by the product's tariff code and where it was made, and it is often followed by extra tariffs, import VAT or GST and processing fees. This calculator adds all of those up from the rates you look up, using the valuation rule your destination country applies, and gives the landed cost per unit so you can price the product.

How to use this tool

Enter the invoice value of the goods, the international freight and the insurance.
Confirm customs valuation adjustments and whether international freight belongs in the duty base.
Enter the duty rate for your tariff code, plus any additional tariffs and specific duty per unit.
Add import VAT or GST and fees, then read the total and the landed cost.

Formula

Duty = customs value × (duty rate + additional tariffs) ÷ 100 + specific duty × units

VAT = (selected value base + duties + VAT adjustment) × VAT rate ÷ 100

Landed cost = goods + freight + insurance + duties + VAT + fees

Use adjusted customs values, not automatically the invoice total. VAT can include taxable incidental costs; add those to its base and include their cost once in fees. Capped fees and nonadditive tariff measures require a separate calculation.

Example

A $25,000 order with $2,200 freight and $150 insurance enters a country that values goods without freight. At a 5% duty rate the duty is $1,250; with a $150 broker fee the total is $1,400, and the landed cost is $28,750, or $28.75 for each of 1,000 units. Under a CIF rule with 20% VAT, a $10,000 order with $1,100 of freight and insurance at 4% duty would pay $444 duty and $2,308.80 VAT.

Frequently asked questions

Where do I find the duty rate?

Look up your product's tariff code in the destination country's tariff schedule — the Harmonized Tariff Schedule for the US, the UK Trade Tariff or the EU's TARIC. The rate depends on the country of origin and any trade agreement you qualify for.

Do additional tariffs always stack?

No. Check the entry date, origin, product, exclusions and the measure itself. This model only adds rates you have confirmed use the same base; it cannot determine tariff applicability.

Who pays the duty?

The importer of record remains responsible under customs law. DDP allocates import costs to the seller between the trading parties; it does not automatically change who customs can hold liable.
