## Frequently asked questions

### What products are classified under HSN 2836

It includes Carbonates & ammonium salts

### Is the composition scheme suitable if I mainly trade Carbonates & ammonium salts?

The composition scheme is optional for eligible small suppliers of goods. You cannot issue tax invoices or collect tax under composition. Check turnover limits and exclusions; evaluate margins and ITC loss before opting in.

### How are warranty replacements of Carbonates & ammonium salts handled?

If replacement is without consideration under a pre‑agreed warranty, issue a delivery challan and reference the original invoice/contract. If consideration is charged, raise a tax invoice. Keep serial/lot details for traceability.

### Can I claim ITC on inputs and services used for Carbonates & ammonium salts?

If your outward supply of Carbonates & ammonium salts is taxable, ITC is generally available (Sections 16–17) except blocked credits (e.g., personal use, motor vehicles in most cases). For exempt supplies, proportionate reversal is required under Rule 42/43.

### Does MRP, weight or pack size change GST treatment for Carbonates & ammonium salts?

Some entries use MRP/weight‑based conditions for classification. Keep pack size, retail marking and brand status on records and invoice to support the chosen HSN.

### If I repair and return Carbonates & ammonium salts, how should I charge GST?

Repair/service is a service supply (SAC). Parts and materials used are goods and may be billed separately with HSN. Mention both lines clearly to avoid mixing service and goods values.
