After reading and re-reading the Customs Act & Customs Tariff Rules, I have come to the conclusion that Customs Duty is calculated as follows:

Let Assessable Value = U
BCD-Basic Customs Duty = 10% of U = V
CVD-Countervailing duty = 12% of (Assessable value + BCD) = 12% of (U+V) = W
Education Cess or Secondary and Higher Education Cess/CESS Applies on both customs and excise duties
Calculated as: Education Cess on CVD duty = 3% of CVD = 3% of W = X
Calculated as: Education Cess on Custom Duty - 3% of (BCD+CVD+Cess on CVD) = 3% of (V+W+X) = Y
SAD- Special additional duty = 4% of (Assessable value+BCD+CVD+Educ.Cess on CVD+Educ. Cess on Custom duty) = 4% of (U+V+W+X+Y) = Z

Total Duty = V + W + X + Y + Z + Service Tax + Brokerage charges (only applicable for Courier Companies not for IndiaPost)

In my case:

U = 8927
V = 893
W = 1,178
X = 35
Y = 63
Z = 442

Total Duty = 2,611 + Service Tax + Brokerage charges

I can assure you that the method is correct. Please double check my calculations and point them if anything is wrong. Rates may be different. I have taken the rates as given in the FedEx invoice.

However, you'll notice that X has not been charged in my invoice. Don't know why. Percentage tax in my case come out to be 28.85%

Now you can know how much Customs Duty (maximum) you'll have to pay when ordering ANYTHING & EVERYTHING fro HobbyKing!!!
