About the Import Export Duty Calculator
What is the Import Export Duty Calculator?
Customs import duty is charged on the assessable value – the CIF value (cost, insurance and freight) converted to rupees at the exchange rate notified by CBIC. Basic customs duty (BCD) applies first, then a 10% social welfare surcharge on the BCD, then IGST on the total.
Enter the FOB value in the invoice currency, freight, insurance and the rates for your product's tariff heading.
How to use the Import Export Duty Calculator
- FOB Value (in the invoice currency) (sample: 20,000)
- Freight (in the invoice currency) (sample: 1,500)
- Insurance (0 = 1.125% of FOB) (sample: 0)
- Customs Exchange Rate (₹ per unit of currency) (sample: 88)
- Basic Customs Duty (%) (sample: 10)
- Social Welfare Surcharge (sample: Yes – 10% of BCD)
- IGST (%) (sample: 18)
- Press Calculate Import Duty (results also refresh as you type). The result card shows the Total Import Duty, along with Assessable value (CIF in ₹), Basic customs duty, Social welfare surcharge and IGST (creditable for GST-registered importers).
Formula used
Duty = BCD + SWS + IGST; IGST = (Assessable value + BCD + SWS) × IGST %
- Assessable value = (FOB + freight + insurance) × customs exchange rate
- Insurance = 1.125% of FOB when the actual amount is not known
- SWS = 10% of BCD, unless exempt
Some goods also attract agriculture infrastructure cess, anti-dumping duty or compensation cess.

Tips for using the Import Export Duty Calculator

- Check the exact tariff rate and exemptions for your HSN code on the CBIC website.
- Free trade agreements can reduce BCD if the goods meet the rules of origin.
