## Frequently asked questions

### What products are classified under HSN 2831

It includes Dithionites & sulphoxylates

### How are warranty replacements of Dithionites & sulphoxylates 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 reverse charge ever apply to transactions involving Dithionites & sulphoxylates?

Reverse charge in goods is notified only for specific categories. Most regular B2B sales of Dithionites & sulphoxylates are forward charge. Check the current notifications for any special cases before deciding.

### Does MRP, weight or pack size change GST treatment for Dithionites & sulphoxylates?

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.

### What are the e‑way bill and e‑invoice points while moving Dithionites & sulphoxylates?

Generate an e‑way bill when the consignment value exceeds ₹50,000, unless exempted for the transaction. E‑invoicing depends on turnover (AATO threshold as notified) for B2B supplies, not on the item itself.

### Is the composition scheme suitable if I mainly trade Dithionites & sulphoxylates?

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 should I document Dithionites & sulphoxylates sent for job work?

Use a delivery challan for sending Dithionites & sulphoxylates to the job worker. Declare movement in your records and reconcile when the goods return. If the job worker raises a service invoice, classify it under SAC; your goods remain under the original HSN.
