Calcium Process vs Sodium Process: Know What You Are Buying
Calcium hypochlorite is made by two main routes. Sodium-process material is generally higher in available chlorine (often around 70%) with fewer insolubles. Calcium-process material, the grade covered here, is typically specified at 65% available chlorine and is usually the more economical option for routine disinfection.
Both routes are supplied as granules, powder and tablets. Granular product flows well, dissolves reasonably quickly and is easy to dose by hand or through feeders, which is why it is the most traded form for:
- swimming pool and spa sanitation;
- municipal and industrial water disinfection;
- bleaching and surface sanitising;
- emergency and remote-site water treatment.
For background on disinfection targets, see the WHO Guidelines for Drinking-water Quality.
Calcium Hypochlorite 65% (Calcium Process) Granular Specifications to Compare
Put these Calcium Hypochlorite 65% (Calcium Process) Granular specifications side by side for every supplier:
| Parameter | What to ask for |
|---|---|
| Available chlorine | 65% minimum, stated at shipment |
| Moisture / water content | Stated value; it affects stability and UN classification |
| Particle size | Granule range, e.g. a stated mesh range |
| Insoluble matter | Stated maximum; affects cloudiness and residue |
| Production date | On every lot; fresher stock holds chlorine better |
| Packaging | Sealed plastic drums with liner |
Ask each supplier for a recent COA and confirm the test method for available chlorine, so the numbers are comparable. Compound data is available on PubChem.

Calcium Hypochlorite 65% (Calcium Process) Granular Container Price and Loading
The Calcium Hypochlorite 65% (Calcium Process) Granular container price depends heavily on the drum size, because drum size sets how many tons fit in a 20 ft container:
| Packing | Load per 20 ft container | Approx. drums |
|---|---|---|
| 45 kg drums | About 14 tons | About 311 |
| 25 kg drums | About 18.15 tons | About 726 |
Freight is charged per container, so a higher payload lowers the freight cost per kilogram. On the other hand, 45 kg drums mean fewer packages to handle. Dangerous-goods surcharges for Class 5.1 also apply, and only some shipping lines accept it on each route; on long, hot routes some buyers choose ventilated or temperature-controlled containers to limit chlorine loss.

The Supplier Comparison Checklist
- Chlorine at arrival, not only at loading. Calcium hypochlorite slowly loses available chlorine, faster in heat. Ask how old the stock is and plan delivery close to use.
- Drum quality. Thick drums, good lids and an inner liner prevent moisture entry and damage.
- Dangerous-goods competence. UN 1748, Class 5.1 cargo needs correct labels, declarations and booking under the IMDG Code.
- Inspection. Agree whether an independent pre-shipment inspection is required.
- Same delivery basis. Compare FOB with FOB and CIF with CIF.
When these points match, you can buy Calcium Hypochlorite 65% (Calcium Process) Granular on price with confidence. Our quality documentation page explains what we provide with each lot.
Safe Storage for Calcium Hypochlorite 65% (Calcium Process) Granular for Water Disinfection
Calcium hypochlorite is a strong oxidiser. Store it in a cool, dry, ventilated area, away from acids, organic materials and combustibles, and keep containers closed. Never mix it with TCCA or other chlorine products: segregate it from TCCA tablets at all times. Rotate stock so the oldest drums are used first.
