Frequently asked questions

PVC and other plastic pipes classify under heading 3917 and are also 18%, so switching between steel and plastic piping doesn't change the tax rate.

For a sale within one state, the 18% splits equally into 9% CGST and 9% SGST. For an interstate sale it is charged as a single 18% IGST — the total tax is the same either way.
