Customs rules
The exchange rate customs uses for imports
Independent site, not a government service. General information, not customs advice.
Duty is calculated in rupees, using a rate that the Board sets, not your bank's. The default of 95 is only an example, so type the notified rate.

Customs value has to be in rupees, so an invoice in dollars or euros has to be converted. The Customs Act addresses that in section 14, whose explanation ties the conversion to the rate of exchange determined by the Board, in force on the date of presentation of the bill of entry under section 46. In other words, your own bank rate, the rate on the day you paid your supplier, or a market rate you saw online does not count for duty. CBIC issues the rates through non-tariff notifications for imported and exported goods. We have not read the notification in force today, so this site publishes no exchange rate. The rate of ₹95 per unit in our calculator is a round number to show how the sum works. Please replace it with the rate your broker or the current CBIC notification gives for the date of your bill of entry.

Where to read the real rate
CBIC publishes exchange rate notifications in its Customs non-tariff series. Our reading on 2 November 2026 did not reach a notification that we could cite, and the DGFT page on currency rates showed an empty table at that time. Secondary websites do publish them, but they disagreed with each other when we looked, so we copied no figure. Your broker has the rate through the customs system.
Which amounts it applies to
All foreign currency amounts in the customs value use the same rate: the goods, freight and insurance. The rate does not touch local rupee costs such as broker fees. In the calculator above, change the rate and watch every line move. Then keep some margin in your landed cost, since the bank rate on the day you pay your supplier will differ, too. Hedging or any treasury decision needs your own adviser, not this page.
