3814

Paint thinners, NC thinner, PVC solvent cement and solvents

The thinner hsn code is 3814, the heading for organic composite solvents and thinners not covered elsewhere, which includes paint thinner, NC thinner, PU thinner and paint removers, and GST on thinner is 18%. Pure chemicals sold as solvents, such as acetone, toluene or mineral turpentine, sit in separate headings, also at 18%.

PVC and CPVC solvent cement, though plumbers call it solvent, is a prepared adhesive under 3506. This page lists each product, a paint dealer's bill and the composite versus single solvent test. Paints are on the paint page.

3814 hsn code: composite solvents

Heading 3814 takes in solvent blends sold as thinners or cleaners when no other heading names them. A paint thinner made by blending toluene, xylene and other solvents is 3814. A single pure chemical, such as acetone, goes to its own Chapter 29 heading. Both are 18%, so the difference matters mainly for the HSN summary.

PVC solvent hsn code

PVC, CPVC and uPVC solvent cements bond pipes and fittings; they are prepared adhesives under 3506 at 18%. See adhesives and PVC pipes.

Turpentine and mineral turpentine

Gum turpentine from pine resin is 3805 at 18%. Mineral turpentine oil, a petroleum solvent, is 2710 at 18%. Both are used to thin oil paints and clean brushes.

Paint dealer's invoice

Paint dealer to a furniture polisher: NC thinner 5 litre, HSN 3814, 20 cans, Rs 8,000. PVC solvent cement, HSN 3506, 50 tins, Rs 4,500. Taxable value Rs 12,500. CGST 9% Rs 1,125. SGST 9% Rs 1,125. Total Rs 14,750.

Thinner gst rate and who uses it

Thinners are bought by painters, furniture polishers, auto body shops, printing units and factories that clean machines. All pay 18%, and those making taxable supplies can take credit. A house owner buying thinner for home painting pays it as a cost. Auto body shops billing repair work at 18% can set off the GST on thinner and paint against their output tax.

NC thinner hsn code

NC thinner, used with nitrocellulose lacquers on furniture and car refinishing, is a composite solvent under 3814 at 18%. PU thinner and epoxy thinner follow the same heading. Thinner sold in bulk drums to factories and in 500 ml tins to painters carries the same code and rate.

Storage and transport of solvents

Thinners are flammable, and loads need correct labelling and, for larger quantities, the transport papers required for hazardous goods. The e-way bill should carry the same HSN as the invoice. A paint shop selling thinner and paint, both at 18%, has a simple tax position; chemical traders selling many solvents should keep each one under its own code.

Solvent sellers should read this summary of heading 3814 as background. Product composition decides the line, so check the maker's data and the GST portal entry, and ask a GST practitioner or chartered accountant about blended products.
