Work out what an imported product really costs per unit once freight, duty and taxes are added.
Assessable value = (FOB + Freight + Insurance) × Exchange rate
BCD = AV × duty %, SWS = 10% × BCD, IGST = (AV + BCD + SWS) × IGST %
Landed cost = AV + BCD + SWS + local charges (+ IGST if you cannot claim input tax credit)
