## Frequently asked questions

### What products are classified under HSN 7303

It includes Cast iron tubes and pipes

### How are warranty replacements of Cast iron tubes and pipes 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.

### Any special steps when selling Cast iron tubes and pipes 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.

### If I repair and return Cast iron tubes and pipes, 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.

### How do I bill a kit or combo that includes Cast iron tubes and pipes?

Prefer separate lines per item with its HSN so each component follows its own tax treatment. If it is a naturally bundled supply, identify the principal supply and tax the whole bundle accordingly.

### What are the e‑way bill and e‑invoice points while moving Cast iron tubes and pipes?

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.
