Base vs GST split. Indicative — verify the exact HSN with your supplier's invoice.
Supply-only vs supply-and-fix (works contract)
Supply only
You buy the door (and hardware) as goods — billed under the item's HSN (4418 / 3925 / 7308 / 7610 / 8302 / 8301) at 18% GST. Installation by your own carpenter is separate.
Supply & fix (works contract)
When the vendor supplies and fixes the door as a single composite contract for immovable property, it's a works contract (SAC 9954), taxed as a service — generally 18% GST for most building work. Rate is the same here, but the HSN/SAC and input-credit treatment differ, so check how your invoice is worded.
Indicative only — not tax advice. GST rates and classifications change; confirm with your CA or the supplier's tax invoice before relying on these figures.
Sense-check the GST and the spec
