HSN 6815: Stone or other mineral substances

HSN code 6815 covers: Stone or other mineral substances; articles thereof (including carbon fibres, articles of carbon fibres and articles of peat), not elsewhere specified or included.

The GST rate for this code depends on the specific item (per CBIC Notification 9/2025-Central Tax (Rate), effective 22 Sep 2025). The official schedule lists:

• 5% — Idols of wood, stone [including marble] and metals [other than those made of precious metals]
• 5% — Sand lime bricks or Stone inlay work
• 18% — Articles of stone or of other mineral substances (including carbon fibres, articles of carbon fibres and articles of peat), not elsewhere specified or included [other than Fly ash bricks Fly ash aggregates; Fly ash blocks]

Pick the line that matches what you're billing.

Rates reflect the 22 Sep 2025 GST 2.0 reform (mainly 5% and 18%, with 3% for precious metals and 28%/40% for select sin and luxury goods). This is a reference drawn from the CBIC rate schedule, not tax advice — confirm the exact rate for your specific item with your CA.
