What we supply

Bleaching Powder in bulk, against a written specification.

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 at 33% minimum available chlorine at despatch, in 50 kg drums. "Stable" grades are made to lose chlorine more slowly in storage, which matters in Indian summer heat. For higher-strength or granular calcium hypochlorite, ask — it is a separate product.

Grades & packing

What goes out, and how it is packed.

These are the formats we most commonly supply. Other concentrations, packing sizes and pack marking are available — ask at the enquiry stage.

Handling & storage

What to get right before the load arrives.

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.

Site notes

  • It loses available chlorine steadily, and faster with heat, moisture and sunlight. Store drums closed, in a cool, dry, shaded, ventilated store, and use stock in rotation.
  • Never let it contact acids — it releases chlorine gas. Keep it well away from ammonia, and from oils, grease, sawdust and other organic material: it is an oxidiser and can start a fire.
  • Transported as dangerous goods (UN 2208, Class 5.1 oxidiser). Handle with gloves, goggles and a dust mask; the dust irritates eyes, skin and lungs.

Price

What actually moves the bleaching powder 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

Bleaching Powder — what buyers ask us.

Can bleaching powder be used to disinfect a water tank?

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.

Why has my bleaching powder lost strength?

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.

Is bleaching powder the same as sodium hypochlorite?

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.

What is the bleaching powder price per kg?

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.

Are you a bleaching powder manufacturer?

No — Velora is a bulk supplier. Bleaching powder is sourced from established Indian manufacturers and supplied in 50 kg drums across India.

What is the HSN code for bleaching powder?

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.
