Accurate GST calculation on invoices

Correct reporting in your GSTR-1 & GSTR-3B

18% GST = ₹9000

Final Invoice total = ₹59000

‍Raw Enzyme Inputs – 18% GST

Chemicals or raw enzymes purchased for preparing enzymes also attract GST at 18%. ITC can be claimed if the final product is taxable.

‍Export of Prepared Enzymes

Exports can be zero-rated under LUT ( without GST payment) or with GST payment and refund claim. HSN Code 3507 must be mentioned in export documents.
