Formula Used

Invoice value: (Quantity × Unit Price − Discount) × Exchange Rate

Customs value: invoice value plus additions required by the selected valuation basis. EXW adds origin, freight, insurance, and assists. FOB adds freight, insurance, and assists. CFR adds insurance and assists. CIF adds assists and other additions.

Effective duty rate: Duty Rate − Preference Reduction, never below zero.

Duty amount: Customs Value × Effective Duty Rate

Surcharge: (Customs Value + Duty Amount) × Surcharge Rate

Excise: percentage mode uses (Customs Value + Duty + Surcharge) × Excise Rate. Fixed mode uses Quantity × Excise Amount per Unit.

VAT base: Customs Value + Duty + Surcharge + Excise + Brokerage + Port Charges

VAT amount: VAT Base × VAT Rate

Landed cost: Customs Value + Total Tax + Brokerage + Port Charges

FAQs

1. What does this calculator estimate?

It estimates customs value, import duty, surcharge, excise, VAT, brokerage, and total landed cost for a shipment using selected valuation assumptions.

2. Why does the valuation basis matter?

EXW, FOB, CFR, and CIF include different cost elements in customs value. Changing the basis changes the taxable amount and final landed cost.

3. What is origin preference reduction?

It models a lower duty rate when trade agreements or origin certificates allow preferential treatment. The calculator subtracts this reduction from the standard duty rate.

4. Can I use this for every country?

Yes for planning, but not for final entry. Every country can apply different customs valuation rules, excise bases, fees, exemptions, and rounding methods.

5. How is VAT calculated here?

VAT is applied to a base that includes customs value, duty, surcharge, excise, brokerage, and port charges. Some jurisdictions use slightly different VAT bases.

6. What happens when the threshold is reached?

If customs value is at or below the entered de minimis threshold, the calculator sets duty and tax components to zero, while leaving logistics fees included.

7. What should I enter for excise?

Choose percent when excise is charged on a tax base. Choose fixed when the authority charges a flat amount for each imported unit.

8. Is the result suitable for pricing decisions?

Yes. It helps compare sourcing options, model landed cost, and set margins before shipping. Confirm final rates with current tariffs and customs brokers.
