HSN code 6814 is the Customs Tariff heading for worked mica and articles of mica, including agglomerated or reconstituted mica, whether or not on a support of paper, paperboard or other materials, in Chapter 68 (Articles of stone, plaster, cement, asbestos, mica or similar materials). The GST rate is 18%: 9% CGST + 9% SGST within a state, or 18% IGST to another state. Rates are from 9/2025-Central Tax (Rate) or 10/2025-Central Tax (Rate), as amended, as of 2026-10-21.
GST rate entries for HSN 6814
These are the entries of the current GST rate notifications whose column (2) names heading 6814 or one of its sub-headings or tariff items. The description is the notification's own wording; the goods must match it for the rate to apply.
| HSN scope | Description of goods (notification wording) | GST | Entry |
|---|---|---|---|
| 6814 | Worked mica and articles of mica, including agglomerated or reconstituted mica, whether or not on a support of paper, paperboard or other materials | 18% | 9/2025-CT(R), Schedule II, S. No. 230 |
Goods of heading 6814 that do not match any description above fall under the residual entry, Schedule II S. No. 639 ("Goods which are not specified in Schedule I, III, IV, V, VI or VII"), at 18%, unless an "Any Chapter" entry or the nil-rated list of Notification 10/2025-Central Tax (Rate) covers them by description.
Chapter 68 entries that can also apply
These entries name the whole of Chapter 68 in column (2), so they reach every heading of the chapter, including 6814, but only for goods that match their description.
| HSN scope | Description of goods | GST | Entry |
|---|---|---|---|
| 44, 68, 83 | Idols of wood, stone [including marble] and metals [other than those made of precious metals] | 5% | 9/2025-CT(R), Schedule I, S. No. 293 |
| 68 | Sand lime bricks or Stone inlay work | 5% | 9/2025-CT(R), Schedule I, S. No. 400 |
| 44 or 68 | Deities made of stone, marble or wood | Nil (0%) | 10/2025-CT(R), S. No. 124 |
CGST, SGST and IGST split for HSN 6814
The rate notifications fix the central tax (CGST). State tax (SGST, or UTGST in a Union territory without a legislature) is levied at the same rate under the matching state notifications, and IGST on an inter-State supply equals the two together.
| Total GST | CGST | SGST / UTGST | IGST |
|---|---|---|---|
| Nil (0%) | 0% | 0% | 0% |
| 5% | 2.5% | 2.5% | 5% |
| 18% | 9% | 9% | 18% |
Worked example: a ₹1,000 sale under HSN 6814
- At nil rate: taxable value ₹1,000.00, no CGST, SGST or IGST, invoice total ₹1,000.00.
- At 5%: taxable value ₹1,000.00. Within your state, CGST ₹25.00 + SGST ₹25.00 = ₹50.00, invoice total ₹1,050.00. To a buyer in another state, IGST ₹50.00, the same total.
- At 18%: taxable value ₹1,000.00. Within your state, CGST ₹90.00 + SGST ₹90.00 = ₹180.00, invoice total ₹1,180.00. To a buyer in another state, IGST ₹180.00, the same total.
For any other amount, the GST calculator gives the same split, and works backwards from a tax-inclusive price.
Billing nil-rated goods of HSN 6814
Entries in Notification 10/2025-Central Tax (Rate) exempt the goods from the whole of the central tax, and the matching state and integrated tax notifications do the same. A registered supplier of only such goods issues a bill of supply instead of a tax invoice. Input tax credit on inputs and services used for these supplies is not available, so a business that sells both taxable and nil-rated goods has to split its credit between them.
How to write HSN 6814 on an invoice
Notification 78/2020-Central Tax sets the number of HSN digits on a tax invoice by the aggregate turnover of the previous financial year. Up to ₹5 crore, print at least 4 digits (6814) on invoices to registered buyers; HSN may be left off invoices to unregistered buyers. Above ₹5 crore, print 6 digits on every tax invoice. Many sellers print the full 8-digit tariff item anyway, because it matches the shipping bill for exports and shows which entry you used.
Charge CGST and SGST when the buyer is in your state and IGST when the place of supply is another state. The invoice also needs your GSTIN, the buyer's GSTIN for B2B sales, the invoice number and date, the quantity, the taxable value and the tax at each rate. The HSN-wise summary in GSTR-1 is built from the same codes, so set the code once per item in your billing software. Make a one-off bill with the free GST invoice generator, or bill every day in FundRaksha Book, which stores the HSN and rate on each item and splits the tax for you.
