Why Distributors Stock TCCA 90% Tablets
Trichloroisocyanuric acid (TCCA) is a stabilised chlorine source with at least 90% available chlorine. When a tablet dissolves it releases hypochlorous acid, which disinfects, together with cyanuric acid, which shields free chlorine from breakdown by sunlight. That combination makes TCCA the standard slow-release chlorine for outdoor pools.
Distributors stock it because it serves several markets from one product:
- swimming pool and spa disinfection through floaters, skimmers and feeders;
- industrial water and cooling system treatment;
- algae control;
- textile and surface sanitising.
The common tablet sizes are 200 g (often called 3-inch), 20 g (1-inch) and small 1–2 g tablets, alongside granules and powder. Multifunction tablets that add a clarifier or algaecide are also traded, but they must be specified separately because their chlorine content is lower.
Trichloroisocyanuric Acid 90% (TCCA 90%) / Tablets Specifications to Fix in the Order
Write the Trichloroisocyanuric Acid 90% (TCCA 90%) / Tablets specifications into your purchase order so every shipment matches the last one:
| Parameter | Typical requirement |
|---|---|
| Available chlorine | 90.0% minimum |
| Moisture | About 0.5% maximum |
| pH of 1% solution | Roughly 2.6–3.2 |
| Tablet weight | e.g. 200 g ± a stated tolerance |
| Appearance | White tablets, no cracks or crumbling |
| Packaging | Sealed plastic drums with liner |
Tablet hardness and dissolution rate matter to end users: a tablet that crumbles in transit or dissolves too fast creates complaints. Ask for the drop-test or dissolution information your customers expect, and confirm values on the COA for each lot. Independent identity data is available on PubChem.

Trichloroisocyanuric Acid 90% (TCCA 90%) / Tablets Shipping as an Oxidiser
TCCA is classified as UN 2468, Class 5.1 (oxidising substance). Trichloroisocyanuric Acid 90% (TCCA 90%) / Tablets shipping therefore follows the dangerous-goods rules of the IMO IMDG Code for sea freight:
- packages carry the correct UN number, class label and marking;
- a dangerous-goods declaration and container packing certificate accompany the shipment;
- not every shipping line or port accepts Class 5.1 on every route, so lead times can be longer than for ordinary cargo.
Never store or ship TCCA with calcium hypochlorite. Mixing the two can cause a violent reaction and fire. Keep them in separate containers, warehouses or clearly segregated areas, and keep both away from acids, ammonia and organic materials.
Our logistics team plans the booking, labelling and documents with you before the goods are loaded.
Trichloroisocyanuric Acid 90% (TCCA 90%) / Tablets Distributor Price: What Moves It
The list price in the key facts table is the starting point. Your Trichloroisocyanuric Acid 90% (TCCA 90%) / Tablets distributor price then depends on:
- Form. Tablets cost more than granules or powder because of pressing and the extra quality control. Compare with our TCCA 90% granules and powder if your customers dose by hand or feeder.
- Pack size. 50 kg and 25 kg drums are cheaper per kilogram than 10 kg or 5 kg retail drums.
- Season. Demand peaks before the pool season in each hemisphere, so ordering early protects both price and lead time.
- Dangerous-goods freight. Class 5.1 surcharges and limited sailings add to landed cost.
To buy Trichloroisocyanuric Acid 90% (TCCA 90%) / Tablets in drums at the best overall cost, combine sizes in one container where possible and fix the specification once, so repeat orders can be quoted quickly.
Advise Customers on Stabiliser Build-Up
Because every TCCA tablet adds cyanuric acid, its level rises in pools that rely only on tablets. Too much stabiliser slows disinfection, and many pool codes set a maximum. Distributors who explain this keep customers loyal: recommend regular testing, partial water replacement when levels climb, and an unstabilised shock such as calcium hypochlorite or SDIC where appropriate, always stored separately.

Frequently asked questions
What is the difference between TCCA and calcium hypochlorite?
TCCA is a stabilised chlorine with about 90% available chlorine that dissolves slowly, ideal for tablets in outdoor pools. Calcium hypochlorite is unstabilised, around 65 to 70% available chlorine, and is often used for shock dosing. They must never be mixed or stored together.
Which TCCA tablet sizes are most common?
200 g tablets are the most widely traded, followed by 20 g tablets and small 1 to 2 g tablets. Granules and powder are also available for feeders and manual dosing.
Is TCCA classified as dangerous goods?
Yes. TCCA is UN 2468, Class 5.1 oxidising substance, so it ships under dangerous-goods rules with the correct labels and declarations.
How should TCCA tablets be stored?
Keep drums closed in a cool, dry, ventilated store away from calcium hypochlorite, acids, ammonia and organic materials, and use stock in date order.
