Trichloroisocyanuric Acid (TCCA 90%) Guide: Pool & Water Disinfection | Jinlida

Trichloroisocyanuric acid (TCCA), often called “trichlor,” is one of the most widely used high-efficiency organic chlorine disinfectants in the world. From keeping swimming pools crystal-clear to protecting drinking water, industrial cooling systems, and crops, TCCA 90% has become a workhorse across the water treatment and sanitation industries. As demand for safe water and hygienic recreation keeps rising, knowing how to choose and use TCCA matters more than ever. This guide explains what TCCA is, why it leads pool sanitization, where it is used beyond the pool, the market trends driving demand in 2026, and how to pick a dependable supplier.

What Is Trichloroisocyanuric Acid (TCCA)?

Trichloroisocyanuric acid (C₃N₃O₃Cl₃, CAS No. 87-90-1) is an organic compound that slowly releases free chlorine when dissolved in water. With a minimum of 90% available chlorine, TCCA delivers broad-spectrum bactericidal, algaecidal, and bleaching performance, effectively killing bacteria, fungi, viruses, and spores. It comes in several forms—fine powder, 8–30 mesh granules, and 5 g, 20 g, or 200 g tablets—so operators can match the format to their dosing equipment and application. TCCA is slightly soluble in water, highly stable in storage, and classified as an oxidizing substance (UN 2468, Class 5.1), which is why proper handling and certified dangerous-goods documentation matter during international shipping.

Why TCCA 90% Is the Preferred Sanitizer for Swimming Pools

Swimming pools are by far the largest end-use market for TCCA, and for good reason. Unlike unstabilized liquid sodium hypochlorite, TCCA carries a built-in cyanuric acid stabilizer that shields free chlorine from rapid ultraviolet degradation, so outdoor pools hold an effective residual longer while using less chemical. Research on tropical pool water shows TCCA also degrades free chlorine more slowly and forms fewer disinfection by-products than sodium hypochlorite—both more efficient and cleaner. A slow-dissolving TCCA tablet in a floating dispenser, skimmer basket, or automatic chlorinator keeps free chlorine at the recommended 1–3 ppm residual while controlling algae and bacteria. For residential pools, hotels, or large commercial aquatic facilities, our swimming pool chemicals range covers tablet and granular formats for reliable, long-lasting sanitation.

Beyond the Pool: TCCA in Water Treatment, Agriculture and Industry

TCCA’s value extends well beyond recreational water. In industry, it disinfects recirculating cooling water, serves as a chlorination treatment agent, and works as a wool shrink-proof inhibitor in textiles. In municipal and emergency settings, it disinfects drinking water and supports health and epidemic prevention. In agriculture, TCCA is a crop seed disinfectant, prevents crop disease, disinfects farmland soil, and helps extend the shelf life of melons, fruits, and vegetables. It also supports sericulture, animal husbandry, and aquaculture, where water quality directly affects productivity. This versatility makes TCCA a strategic chemical for suppliers serving multiple industries under one product line, and it sits naturally within our water treatment chemicals portfolio.

Global TCCA Market Outlook 2026: What's Driving Demand

The global trichloroisocyanuric acid market continues to grow. Grand View Research values it at roughly USD 2.3 billion, projecting a compound annual growth rate (CAGR) of about 4.7% to USD 3.3 billion by 2033, with Asia-Pacific leading global demand. Several forces drive this growth: heightened hygiene and waterborne-disease awareness—accelerated since the COVID-19 pandemic—has raised water quality standards in pools, spas, and municipal systems; stricter government regulations push operators toward certified chlorine products; and the global pool and wellness industry is expanding in hospitality and residential construction. Together, these trends point to sustained demand for high-quality TCCA 90%.

TCCA vs. SDIC vs. Calcium Hypochlorite: How to Choose

When selecting a chlorine sanitizer, buyers often compare TCCA with sodium dichloroisocyanurate (SDIC) and calcium hypochlorite (CHC):

•  TCCA 90%: highest available chlorine among stabilized options, slow-release and UV-stabilized—ideal for pools, tablets, and long-term sanitation.

•  SDIC: dissolves quickly and lowers pH less, convenient for shock treatments; typically around 56–60% available chlorine.

•  Calcium hypochlorite: fast-acting at ≈65–70% chlorine, but adds calcium (scale risk) and lacks UV stabilization, so it degrades faster outdoors.

For most pool and water treatment operators wanting low maintenance, consistent residuals, and stable storage, TCCA 90% tablets or granules are the most cost-effective long-term choice. Where rapid shock dosing or pH sensitivity matters, SDIC may suit better. Matching the chemical to your dosing system is the key to a clean, efficient operation.

How to Choose a Reliable TCCA Supplier

Quality varies significantly among manufacturers, so buyer diligence pays off. Look for a supplier that guarantees a minimum 90% available chlorine with low moisture (≤0.3%) and few impurities, and that provides complete documentation—COA, MSDS, and dangerous-goods certificates—for smooth customs clearance. Flexible options matter too: whether you need a small trial order to validate quality or full-container bulk supply, an adaptable partner reduces supply risk. Standard 50 kg drums, multiple product forms, and timely technical guidance all signal a professional manufacturer. Explore our company website to see our full chemical portfolio.
