## Frequently asked questions

### What products are classified under HSN 2920

It includes Inorganic acid esters and salts

### Does packaging or branding change how GST applies to Inorganic acid esters and salts?

Yes. Many food/agri goods are treated differently when sold as pre‑packaged & labelled retail packs versus loose/open packs. If Inorganic acid esters and salts is sold in small pouches (e.g., 500 g) with an MRP and label, record that on the invoice. Loose bulk bags often follow a different treatment.

### How are warranty replacements of Inorganic acid esters and 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.

### Does MRP, weight or pack size change GST treatment for Inorganic acid esters and 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.

### Any special steps when selling Inorganic acid esters and salts through an e‑commerce platform?

Ensure registration requirements are met and reconcile the operator’s TCS statements with your GSTR‑2B/3B. Map SKU descriptions to HSN to reduce mismatches and returns.

### Can reverse charge ever apply to transactions involving Inorganic acid esters and salts?

Reverse charge in goods is notified only for specific categories. Most regular B2B sales of Inorganic acid esters and salts are forward charge. Check the current notifications for any special cases before deciding.
