Zinc oxide in 25 kg bags for rubber, ceramics, paint and chemical users, normally 99.5% to 99.7% grade, with feed-grade material sourced to its own specification. Price on request against your quantity and delivery point.

What we supply
Zinc oxide is a fine white powder that works as an activator, a pigment and a zinc source at the same time. Rubber compounders are the largest buyers in India: zinc oxide activates the sulphur cure, so tyre, tube, footwear and moulded-goods plants take it by the tonne.
Velora supplies 99.5% and 99.7% grades in 25 kg bags, and sources feed grade — a lower assay material — to its own specification. Assay, particle size and heavy-metal limits are confirmed against the producer's certificate of analysis for your lot before you order. Tell us the process — rubber, ceramic frit, paint, feed premix or chemical synthesis — because surface area and heavy-metal limits differ by application, and the grade that suits a tyre plant is not the one a feed blender needs.
Grades & packing
These are the formats we most commonly supply. Other grades, packing sizes and pack marking are available — ask at the enquiry stage.
| Product | Formula | Grade | HSN | Packing |
|---|---|---|---|---|
| Zinc Oxide | ZnO | 99.5% – 99.7% | 2817 00 10 | 25 kg bag |
No tested values are published here. The certificate of analysis for the batch actually loaded travels with the despatch documents, and a representative COA and the safety data sheet go out before any commercial discussion.
Applications
Cure activator with stearic acid in the sulphur vulcanisation system; also improves heat conduction in the compound.
Flux in glazes and frits, lowering firing temperature and improving craze resistance.
White pigment and mildew-resistant additive in some primer and coating systems.
Zinc source in mineral premixes, where feed-grade material is specified.
Raw material for zinc salts and a catalyst component.
Handling & storage
Worth reading before you order rather than after. If any of this is a problem at your site, tell us — it usually changes what we would quote.
Price
Zinc oxide is priced off the zinc metal price — the LME number as it feeds through to the Indian domestic zinc price — because roughly 80% of the product's weight is zinc. Grade, particle size and bag size add to that, and freight matters less than for most bulk chemicals because the value per tonne is high. Offers carry a short validity for the same reason.
Questions
Zinc oxide is quoted per kg, landed, and tracks the zinc metal price closely, so offers carry a short validity. Grade and particle size move it as well. Send the application, quantity and delivery point for a written offer.
Rubber compounders normally use 99.5% or higher indirect-process (French process) zinc oxide. In India a good deal of indirect-process material is made from secondary zinc, and it is that feedstock rather than the process name that drives the lead and cadmium levels. Tell us the compound and cure system and we will confirm the grade and the impurity limits before quoting.
No. We supply industrial and feed-grade material in bulk. Cosmetic and pharmacopoeial grades are a different specification with their own certification, and we do not sell retail packs.
Zinc oxide is quoted per kg, landed. Around 80% of its weight is zinc, so the price moves with the zinc metal market and offers carry a short validity. Grade and particle size move it too.
No — Velora is a bulk supplier. Zinc oxide is sourced from established Indian producers and supplied in 25 kg bags.
The HSN code for zinc oxide is 2817 00 10 (Zinc oxide). Source: the Indian customs tariff as listed in the GST HSN directory, checked September 2026.
Documentation
Shipped as a dangerous good under UN 3077. A TREM card travels on the vehicle.

| Representative COA | A producer’s representative certificate of analysis for the grade you specify, obtained at enquiry stage so your QC can assess zinc oxide against your own specification | Before commercial terms |
| Batch COA | Tested values for the batch actually loaded on your vehicle | With despatch documents |
| Technical data sheet | Handling, storage and materials-of-construction guidance | On request |
| TREM card | Transport emergency information for the driver, on the vehicle | With the consignment |
We do not publish blank certificates to download. A certificate of analysis belongs to a batch, so a generic one tells you nothing about the material on your vehicle — and the safety data sheet is the producer’s document for the grade actually quoted. Ask and both are emailed, usually the same working day.
