Calcium Hypochlorite Supplier and Exporter for Water Treatment and Industry
Content reviewed: 5 October 2026 · SUHA International Trading L.L.C., Dubai & Ankara
SUHA International Trading is a calcium hypochlorite supplier and exporter with offices in Dubai (UAE) and Ankara (Türkiye). We supply calcium hypochlorite with 65–70% available chlorine as granules, powder or tablets, packed in 25 kg, 45 kg or 50 kg drums, for municipal water treatment, swimming pools, industrial sanitation and bleaching. Minimum order is one full container load (1 × 20ft FCL), quoted FOB, CFR or CIF, with a certificate of analysis and SDS for every shipment.
Calcium hypochlorite (Ca(ClO)₂) is a premier disinfectant and bleaching agent, distinguished by its high available chlorine content (typically 65–70%), potent oxidizing capabilities and extended disinfection performance. Because it is a dry solid, it carries roughly five times more available chlorine per kilogram than liquid sodium hypochlorite and stores far longer – which is why water utilities, pool-chemical distributors and importers buy it by the container.
As a bulk calcium hypochlorite supplier, we handle grade selection, dangerous-goods documentation and booking with shipping lines, so you receive a compliant Class 5.1 cargo at your port – or, inside Türkiye, at your warehouse.

What Is Calcium Hypochlorite?
Calcium hypochlorite is an inorganic compound that presents as a white or grayish solid. When dissolved in water, it readily releases chlorine to form hypochlorous acid (HOCl), a powerful antimicrobial agent highly effective at neutralizing bacteria, viruses and algae. It offers an optimal balance of efficiency, safety and cost-effectiveness, making it one of the most trusted chlorine-based compounds in the world. In the trade it is also called cal hypo, chlorine granules, granular chlorine or pool shock.
Its disinfecting power depends on water pH: below about pH 7.5 most of the free chlorine is present as hypochlorous acid, the stronger disinfectant; at higher pH more of it becomes the weaker hypochlorite ion (OCl⁻). Because calcium hypochlorite is alkaline, pool and water-system operators check pH together with free-chlorine residual.
Calcium hypochlorite is not the same as bleaching powder (chlorinated lime). Bleaching powder has roughly 35% available chlorine; commercial calcium hypochlorite has 65–70%, so it needs about half the weight, storage space and freight for the same chlorine dose.
Key Properties of Calcium Hypochlorite
| Property | Value |
|---|---|
| Chemical Formula | Ca(ClO)₂ |
| Appearance | White or grayish granules, powder, or tablets |
| Chlorine Content | 65–70% (Standard Grade) |
| Solubility | 21 g/100 mL in water |
| pH (1% Solution) | 11–12 (mildly alkaline) |
| Odor | Characteristic chlorine scent |
| Oxidizing Ability | High, ensuring effective bleaching and disinfection |
Other reference data: molar mass 142.98 g/mol, density about 2.35 g/cm³, decomposition from about 175 °C. Solubility is quoted at 25 °C; commercial grades also contain a small insoluble fraction (see the technical data sheet below), so many operators dissolve granules in a separate tank and dose the clear solution.
How Calcium Hypochlorite Is Made: Manufacturer Routes
Calcium hypochlorite is synthesized through a controlled chemical reaction between chlorine gas and calcium hydroxide (slaked lime):
2Cl₂ + 2Ca(OH)₂ → Ca(ClO)₂ + CaCl₂ + 2H₂O
The crude product is filtered, dried, then granulated or pressed into tablets. Every calcium hypochlorite manufacturer uses one of two industrial routes, and the route largely decides the grade:
- Calcium process – chlorination of lime alone. Simpler, but it leaves more calcium chloride in the product, typically giving around 65% available chlorine.
- Sodium process – sodium hydroxide is used so that by-product chloride leaves as sodium chloride. It gives a purer product with up to about 70% available chlorine and better storage stability.
Buying from a manufacturer or from a calcium hypochlorite trading company? Producers usually sell a single plant's output under fixed terms; a trading company such as SUHA combines several approved sources, so we can match grade, form, packing and shipping date to your order and handle export documents from one desk.
Calcium Hypochlorite 65% and 70%: Grades, Granules and Tablets
As a calcium hypochlorite 65% supplier and calcium hypochlorite 70% supplier, we offer both strengths, so you can choose between lower cost per tonne and higher chlorine per kilogram.
High-Strength Grade (65-70%)
The most common and versatile grade, valued for its high concentration of available chlorine. It is ideal for large-scale applications such as municipal water treatment, commercial swimming pools and industrial sanitation, where maximum disinfecting power is required. Its high potency allows lower dosage rates, making it a cost-effective way to achieve reliable disinfection.
Medium-Strength Grade (40-60%)
This grade contains a lower concentration of active chlorine and is often blended with other stabilizers or agents. It is suited for less demanding applications, including residential pools, smaller-scale wastewater treatment and certain agricultural hygiene tasks.
Granules, powder and tablets
- Granular – the main export form. As a calcium hypochlorite granules supplier, we ship granules for shock chlorination, batch dosing and dissolving tanks.
- Powder – dissolves fastest; used in mixing tanks and bleaching.
- Tablets – slow-dissolving tablets for erosion feeders, pools and small water systems. As a calcium hypochlorite tablets supplier, we confirm tablet size and dissolution rate on the quotation.
Calcium hypochlorite compared with other chlorine sources
| Product | Form | Typical available chlorine | When buyers choose it |
|---|---|---|---|
| Calcium hypochlorite | Granules, powder, tablets | 65–70% | Concentrated, long shelf life, easy to ship and store; adds calcium hardness |
| Sodium hypochlorite | Liquid | About 10–15% | On-site pump dosing where liquid handling exists; loses strength faster in storage |
| TCCA (trichloroisocyanuric acid) | Tablets, granules | About 90% | Stabilised outdoor-pool chlorine; adds cyanuric acid, which builds up over time |
| Bleaching powder (chlorinated lime) | Powder | About 35% | Low-cost sanitation where strength and stability matter less |
Never mix calcium hypochlorite with TCCA or other chlorine products – see the safety section.

How Much Calcium Hypochlorite Do You Need?
For a quick estimate, every 1 mg/L (ppm) of chlorine in 1 m³ of water needs 1 g of available chlorine. Divide by the product strength to get the weight of calcium hypochlorite:
grams = volume (m³) × target dose (mg/L) ÷ available chlorine (as a fraction)
Theoretical dose only. Real demand is higher because organic matter, ammonia and sunlight consume chlorine – always confirm with a free-chlorine residual test and follow your local drinking-water or pool regulations.
Applications and Uses of Calcium Hypochlorite
1. Water Treatment and Purification

Shipping line rules for calcium hypochlorite
Calcium hypochlorite is a Class 5.1 oxidizer under the IMDG Code, and some shipping lines apply stricter acceptance rules than the code itself. Industry guidelines published by CINS and the International Group of P&I Clubs recommend plastic drums of no more than 45 kg, a reduced net weight per container and stowage shaded from heat. Depending on the carrier and route, the loadable weight per container can therefore be below the figures above – we confirm the accepted packing and weight with the line before we quote.
Estimate only. Final package and container counts are confirmed on the packing list for each contract.

Calcium Hypochlorite Price: What Drives It
There is no exchange-traded benchmark for calcium hypochlorite, so the price is set contract by contract. These are the factors behind every quotation:
- Available chlorine – 70% (sodium process) sells above 65% (calcium process).
- Form – tablets cost more than granules because of pressing and packing.
- Packing – drum size, private labelling and jumbo bags change cost per tonne.
- Chlorine, lime and energy costs – the main raw-material drivers at the producer.
- Freight – dangerous-goods surcharges and carrier weight limits for Class 5.1 cargo affect the delivered price per tonne.
- Season – northern-hemisphere pool season tightens supply in spring and summer.
- Trade measures – some importing countries apply anti-dumping or countervailing duties to certain origins, which changes the landed price.
Demand is rising: Grand View Research valued the global calcium hypochlorite market at about USD 746 million in 2025 and expects around 8.8% annual growth to 2033, with water treatment the largest application. For a firm calcium hypochlorite price, send your grade, quantity and destination – we reply with a dated quotation.

- Oils, solvents, sugar, sawdust or other organic matter – fire risk
A Safety Data Sheet (SDS) is provided with every shipment to support regulatory compliance and safe handling.
Calcium Hypochlorite FAQ
What is calcium hypochlorite used for?
Calcium hypochlorite is mainly used to disinfect drinking water, swimming pools and wastewater. It is also used to sanitize surfaces and equipment in food, beverage and healthcare settings, to disinfect irrigation and livestock water, and as a bleaching agent in textile, paper and detergent manufacturing.
Is calcium hypochlorite the same as chlorine or bleach?
Calcium hypochlorite is a solid source of chlorine: in water it releases the same active disinfectant, hypochlorous acid, as household bleach. Household bleach is liquid sodium hypochlorite at a few percent strength, while calcium hypochlorite is a dry granule or tablet with 65–70% available chlorine.
Is calcium hypochlorite safe for drinking water?
Yes, when it is dosed correctly. Calcium hypochlorite is one of the most widely used chemicals for drinking-water disinfection. For potable use, check the heavy-metal limits on the technical data sheet and any standard your regulator or tender requires, such as EN 900, AWWA B300 or NSF/ANSI/CAN 60.
How much calcium hypochlorite do I need per 1,000 litres of water?
To raise 1,000 litres (1 m³) of water by 1 mg/L of chlorine you need about 1.4 g of 70% calcium hypochlorite or 1.5 g of 65%. For emergency household treatment, the US EPA suggests dissolving one heaping teaspoon of granular calcium hypochlorite in two gallons of water to make a stock solution, then adding one part of that solution to 100 parts of water.
Calcium hypochlorite or sodium hypochlorite – which is better?
Calcium hypochlorite is a solid with 65–70% available chlorine and a long shelf life, so it is cheaper to ship and store. Sodium hypochlorite is a liquid with about 10–15% available chlorine that is easy to pump but loses strength faster. Solid calcium hypochlorite suits remote sites, export and long storage; liquid suits plants with existing pump dosing.
What is the difference between 65% and 70% calcium hypochlorite?
The percentage is the available chlorine. 70% grades are usually made by the sodium process and contain less calcium chloride, so they are purer and more stable in storage. 65% grades are often made by the calcium process and cost slightly less per tonne.
Is calcium hypochlorite good for swimming pools?
Yes. Calcium hypochlorite is a common pool shock and daily chlorinator. It does not add cyanuric acid, unlike TCCA, but it does raise calcium hardness and pH, so pool operators monitor both.
Is calcium hypochlorite dangerous? Can it explode?
It is a strong oxidizer and corrosive. It can start fires or react violently if mixed with acids, ammonia, organic materials or other chlorine products such as TCCA, or if it is contaminated and heated. Stored cool, dry, sealed and separated from incompatible materials, and handled with gloves, goggles and respiratory protection, it is used safely worldwide.
How do you dissolve calcium hypochlorite?
Always add calcium hypochlorite to water, never water to the product. Stir in a clean plastic container, let the insoluble residue settle and dose the clear solution. Use a separate container that has never held acids or other chemicals.
What is the shelf life of calcium hypochlorite?
Stored sealed in a cool, dry place away from sunlight, calcium hypochlorite keeps its strength well and loses only a small amount of available chlorine per year. Heat, humidity and open drums speed up decomposition, so use stock first in, first out.
What is the price of calcium hypochlorite per ton?
Calcium hypochlorite price depends on available chlorine (65% or 70%), form (granules or tablets), packing, quantity, Incoterm and freight for Class 5.1 cargo. There is no public benchmark, so send your grade, quantity and destination for a dated quotation.
Should I buy from a calcium hypochlorite manufacturer or a supplier?
A manufacturer sells one plant's output on its own terms and minimums. A supplier or trading company sources from several approved producers, so it can offer both 65% and 70% grades, granules and tablets, mixed packing and flexible shipping dates, and handles export documents and dangerous-goods booking for you.
How do I choose a reliable calcium hypochlorite supplier?
A reliable calcium hypochlorite supplier publishes a technical data sheet, provides a certificate of analysis and SDS for every lot, packs in UN-approved moisture-proof drums, can book Class 5.1 dangerous-goods cargo with shipping lines and states MOQ, packing and container loading clearly.
Do you supply calcium hypochlorite in Turkey?
Yes. From our Ankara office we supply calcium hypochlorite to all 81 provinces of Türkiye, and as a calcium hypochlorite exporter we load at Mersin port, FOB, CFR or CIF.
What is the minimum order and how is calcium hypochlorite packed?
Our minimum order is one full container load (1 × 20ft FCL). We pack in 25 kg and 45 kg plastic drums, 50 kg HDPE drums or 1000 kg jumbo bags; a 20ft container carries approximately 19.8–20 metric tons and a 40ft approximately 24 metric tons, subject to the shipping line's rules for Class 5.1 cargo.
What is the HS code and UN number for calcium hypochlorite?
Calcium hypochlorite is classified under HS code 2828.10. For transport it is UN 1748 (dry) or UN 2880 (hydrated), Class 5.1 oxidizer. Its CAS number is 7778-54-3.
Is calcium hypochlorite the same as bleaching powder?
No. Bleaching powder (chlorinated lime) has roughly 35% available chlorine, while commercial calcium hypochlorite has 65–70%. Calcium hypochlorite therefore needs about half the weight for the same chlorine dose and stores better.
