## Frequently asked questions

### What products are classified under HSN 3913

It includes Natural polymers in primary forms

### Any special steps when selling Natural polymers in primary forms 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.

### How should I document Natural polymers in primary forms sent for job work?

Use a delivery challan for sending Natural polymers in primary forms 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.

### How are warranty replacements of Natural polymers in primary forms 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 packaging or branding change how GST applies to Natural polymers in primary forms?

Yes. Many food/agri goods are treated differently when sold as pre‑packaged & labelled retail packs versus loose/open packs. If Natural polymers in primary forms 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.

### Is the composition scheme suitable if I mainly trade Natural polymers in primary forms?

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.
