What we supply
Bleaching powder is made by passing chlorine over slaked lime. What you buy is a mixture of calcium hypochlorite with calcium chloride and lime, and what you pay for is its available chlorine — the part that actually disinfects and bleaches.
Velora supplies stable bleaching powder to IS 1065 in 50 kg drums, quoted against the producing plant's certificate of analysis for the lot. IS 1065 has been published in two parts since 2019 — Part 1 for household and industrial use, Part 2 for water intended for drinking, which additionally caps lead and arsenic — so tell us which part and grade you need and we will say whether we can source to it. "Stable" grades are made to lose available chlorine more slowly in ordinary storage, which matters in Indian summer heat; it does not mean the material is inert. For higher-strength or granular calcium hypochlorite, ask — it is a separate product.
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 |
|---|---|---|---|---|
| Bleaching Powder | Ca(OCl)₂ | 32–34% av. Cl (IS 1065) | 2828 10 10 | 50 kg drum |
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
Disinfection of wells, storage tanks and small water supplies, especially where there is no chlorine dosing plant.
Disinfection of drains, public areas and flood-affected zones.
Surface and drain disinfection.
Bleaching of cotton, linen and pulp.
Oxidation and disinfection of treated effluent.
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
The price follows chlorine and lime costs and the chlor-alkali balance, and demand rises sharply around the monsoon when municipal and public-health buying peaks. Drum size, freight and quantity set the rest. We quote per kg in writing, and we state the available-chlorine basis so quotes can be compared fairly.
Questions
Yes — it is widely used for disinfecting water storage tanks and wells. The dose depends on the water volume and its chlorine demand, so follow the procedure set by your local health authority or water engineer, and let the treated water stand for the prescribed time before use.
Available chlorine decays over time, faster when drums are left open, damp or hot. Buying in quantities you will use within the season and storing the drums properly is the only fix.
Both disinfect with hypochlorite, but bleaching powder is a calcium-based solid and sodium hypochlorite is a liquid. Liquid suits dosing pumps; powder keeps its strength better than liquid hypochlorite, so it suits sites that dose by hand or store for weeks rather than days.
Bleaching powder is quoted per kg, landed, at a stated available-chlorine level. It follows chlorine and lime costs and rises with monsoon demand. Compare quotes on available chlorine, not only price per kg.
No — Velora is a bulk supplier. Bleaching powder is sourced from established Indian manufacturers and supplied in 50 kg drums across India.
The HSN code for bleaching powder is 2828 10 10 (Commercial calcium hypochlorite (bleaching paste or powder)). Other calcium hypochlorite grades fall under 2828 10 90. Source: the Indian customs tariff as listed in the GST HSN directory, checked September 2026.

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.
