TCCA 90 is the highest available chlorine grade among the stabilized chlorine family — trichloroisocyanuric acid (C3Cl3N3O3) with a guaranteed minimum of 90% available chlorine. Every kilogram of TCCA 90 delivers more active sanitizer than any other cyanurate-based disinfectant on the market, while its built-in cyanuric acid stabilizer (~55-58%) shields the chlorine from UV destruction in outdoor water. Everglory Industrial manufactures and exports TCCA 90 in granular form (8-30 mesh and 14-50 mesh) and tablet form (200g and 20g) to distributors, pool service companies, and water treatment contractors in more than 60 countries. All production runs under an ISO 9001 certified quality system and ships in UN 2468 approved plastic drums with complete dangerous goods documentation.

Why Choose TCCA 90 Over Lower-Chlorine Grades

• Highest chlorine content per kilogram: At 90% minimum available chlorine, TCCA 90 outperforms SDIC (56%/60%) and matches no other stabilized solid — one kilogram replaces roughly 1.4 kg of 65% calcium hypochlorite in sanitizing power, reducing the physical volume a buyer must store and handle
• Cyanuric acid UV protection built in: The ~55-58% cyanuric acid content forms a weak bond with free chlorine that slows photodegradation by sunlight, extending chlorine life in outdoor pools by three to five times compared with unstabilized chlorines
• No calcium hardness buildup: Unlike calcium hypochlorite, TCCA 90 adds zero calcium to the water, preventing scale formation on heaters, pipes, and pool surfaces — a decisive advantage in hard-water regions
• Long shelf life: Properly drummed TCCA 90 retains its chlorine content for 24 months, letting distributors hold stock through seasonal demand cycles without quality loss
• Lower freight cost per unit of chlorine: Because 90% of every kilogram is active chlorine, buyers ship less inert material per container — more sanitizing value in each 20ft load and a lower landed cost per kg of available chlorine

TCCA 90 Specifications

TCCA 90 vs Calcium Hypochlorite

Both chemicals are first-class pool and water treatment sanitizers, but their chemistry differs in ways that matter to specifiers. The comparison below summarizes the practical differences between TCCA 90 and 65-70% calcium hypochlorite:

Critical compatibility warning: Never mix TCCA 90 with calcium hypochlorite — in dry or concentrated form this combination can trigger a violent reaction, heat release, and toxic gas evolution. In practice this means never dosing the two products through the same feeder, never storing them in the same drum or spill zone, and never adding one to water that still contains concentrated residue of the other.

Applications of TCCA 90

• Outdoor residential pools: Daily and weekly disinfection where sunlight would rapidly destroy unstabilized chlorine — the core market for TCCA 90 granular and tablets worldwide
• Commercial and hotel pools: Erosion feeders charged with 200g TCCA 90 tablets deliver automated, labor-saving sanitation for high-bather-load outdoor facilities in resort regions
• Drinking water treatment: Municipal and rural systems use TCCA 90 granular in dissolving chambers for controlled residual chlorination of potable water supplies
• Aquaculture: Hatcheries and grow-out farms apply dilute TCCA 90 solutions to disinfect ponds, tanks, and equipment between production cycles
• Cooling water treatment: Industrial recirculating cooling systems dose TCCA 90 to control algae, bacteria, and biofilm in towers and heat exchangers
• Emergency and disaster relief: Compact 20g tablets and small drums make TCCA 90 a standard item in humanitarian water purification kits for floods, earthquakes, and refugee situations

TCCA 90 Dosing Guidelines

Dosage varies with water condition, temperature, and bather load. The table below gives typical starting rates for TCCA 90; always verify free chlorine residual with a test kit and adjust to maintain 1-3 mg/L in pool water:

Packaging and Storage

As a Class 5.1 oxidizer, TCCA 90 ships exclusively in UN 2468 certified plastic drums with inner liners. Everglory Industrial offers the full drum range for granular and tablet shipments:

Store TCCA 90 in a cool, dry, well-ventilated area away from direct sunlight and moisture. Most importantly, keep it physically separated from calcium hypochlorite, acids, ammonia, and combustible organic materials — separate storage zones with no shared spill containment. Keep drums sealed and re-close tightly after opening. Under these conditions, the product holds its 90% minimum available chlorine for the full 24-month shelf life.

Quality Assurance

• COA per batch: Every production batch of TCCA 90 is laboratory tested for available chlorine, moisture, and pH, and ships with a Certificate of Analysis matched to the batch number printed on the drum
• Full MSDS documentation: Material Safety Data Sheets supplied in English, French, or Spanish for customs, transport, and end-user compliance
• UN 2468 packaging certificate: All drums carry valid UN 2468 performance certification for Class 5.1 dangerous goods, accepted under the IMDG code for sea freight
• ISO 9001 certified system: Production, testing, and documentation run under an ISO 9001 certified quality management system audited annually
• Third-party inspection welcome: SGS, BV, or Intertek pre-shipment inspection can be arranged at the buyer's request, including container loading supervision
