Stamps are goods under 9611
Heading 9611 covers date, sealing or numbering stamps and similar devices designed for operating in the hand, and is in the 18% schedule after 22 September 2025. Rubber stamps made to a customer's text are still goods under 9611, not a printing service, because the customer buys a finished article. The maker charges 18% on the full price, including the design and setting of the text.
Ink pads and inks
Inked pads are listed in heading 9612, which covers typewriter or similar ribbons and ink-pads, at 18%. Stamp inks and refill bottles are inks of heading 3215, also at 18%. Keep the HSN per item on the invoice; a shop that sells a stamp with a spare pad and an ink bottle has three HSNs on one bill, all at the same rate.
Composition for small stamp makers
A stamp maker whose turnover is under Rs 1.5 crore and who makes and sells within one state can opt for the composition scheme for manufacturers at a low rate on turnover. Under composition, the maker issues a bill of supply, charges no GST to customers and cannot pass input tax credit, which may put off company buyers who want credit. Makers who do a lot of business with offices often stay regular.
Laser engraving and nameplates
Many stamp shops also make acrylic nameplates and engraved signs. These are not stamps; acrylic nameplates are articles of plastics under 3926 and metal plates have their own headings, generally at 18%. List them on separate lines so the stamp heading is not used for everything the shop makes.
Bulk orders for organisations
Banks, colleges and government offices order dozens of stamps at once. Issue a single tax invoice with a line per stamp design, quote the purchase order, and where the buyer is a government department with a contract value above Rs 2.5 lakh, expect TDS at 2% under section 51.
Same-day and online orders
Many stamp makers now take orders by WhatsApp or through marketplaces and courier the stamp. For a marketplace order, the platform reports the sale and collects TCS, so the invoice should carry the order ID and the delivery state. Orders delivered to buyers in another state need IGST instead of CGST plus SGST, and an online stamp seller needs to check whether its registration covers sales through e-commerce operators. Courier charges recovered from the customer are part of the value of the stamp and are taxed with it at 18%.
