Frequently Asked Questions

Clear answers to common queries about HSN Sub Chapter 7303 and GST compliance.

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.
