## Frequently asked questions

### What products are classified under HSN 3908

It includes Primary forms polyamides

### How should I document Primary forms polyamides sent for job work?

Use a delivery challan for sending Primary forms polyamides 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.

### Do spares or accessories of Primary forms polyamides follow the same HSN?

Not always. Spares are often classified by their own description or by the function/part rule. Check if a specific sub‑heading exists for parts of the main item and describe the part on the invoice.

### Does MRP, weight or pack size change GST treatment for Primary forms polyamides?

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 Primary forms polyamides 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 are warranty replacements of Primary forms polyamides 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.

### What should my invoice and records include for Primary forms polyamides?

Include HSN, exact description, pack size/grade, quantity, and if pre‑packaged & labelled. Maintain purchase specs, test reports (where relevant), and job‑work challans for audit trail.
