The total value on Invoice copies of Miners including shipping cost is 12005.43 USD (5x1445 + 2x1445 + 1x1378 + shipping cost), going by the amount of Duty fee I paid for the power supply units, I'm sure the duty fee for the miners will be more than 2,65,000 INR and have to see if they'll fine anything extra. I will update this thread when Duty fee on the Miners is calculated.
at last how much how much did you pay?
As now, according to my findings, taxes are:
customs duty is 10%
GST is 18%
suppose product cost= X
so, the amount will be:
X + shipping + 0.10X (customs) + 0.18(1.10X) (GST)
= 1.298X + shipping (29.8% extra from original amount)
so, you are right, % of duties and tax might be sum up around 30%
this is again my assumptions, please let us know how much did you pay?
