Products
TCCA granular is the free-flowing granulated form of trichloroisocyanuric acid, the 90% available chlorine disinfectant built on the cyanuric acid ring. Sized to a single trade standard — 8-30 mesh — the granular grade dissolves at a controlled, predictable rate that suits pool shock dosing, dissolving-tank feeding and dry-feed water treatment programs, while the built-in cyanuric acid stabilizer shields the released chlorine from UV destruction. Everglory Industrial manufactures and exports TCCA granular from its own ISO 9001 production lines, shipping in UN 2468 certified plastic drums with a batch Certificate of Analysis to importers and water treatment contractors worldwide.
Granular, Granules, and Why the Names Vary
Procurement teams meet the same product under two spellings: the singular "granular" is the more common form in North American and inland trade, while buyers in the United Kingdom, West Africa and much of South Asia specify tcca granules in tenders and RFQs. The two terms describe one grade — white free-flowing granular solid, 90% minimum available chlorine, 8-30 mesh — and Everglory's shipping documents carry the full chemical name trichloroisocyanuric acid 90% granular so customs and receiving laboratories can reconcile the consignment with either wording. The specification below is the binding reference for both spellings:
Why 8-30 Mesh Is the Reference Grade
The 8-30 mesh window is deliberately narrow because granulometry drives everything downstream of the drum. The coarse, uniform bead of tcca granular pours cleanly through volumetric feeders without bridging, dissolves evenly across the pool or dosing tank rather than clumping, generates minimal dust during handling, and resists the caking that finer material suffers in humid climates. Buyers who specify tcca granules from many suppliers receive inconsistent particle distributions; Everglory's sieve analysis, recorded on every COA, verifies that at least 90% of the granular mass sits inside the 8-30 mesh band before the lot is released for packing.
Where Granular Fits in the TCCA Form Matrix
Tcca 90 granular is one of three physical forms of the same molecule, and the choice between them is an application decision rather than a chemistry decision. Granular suits direct hand-dosing, shock treatment and dissolving tanks; powder suits rapid-dissolution duties; tablets suit erosion feeders and slow-release programs. The full chemistry, grade comparisons against SDIC and calcium hypochlorite, and dosing guidance are covered on the TCCA 90 product page, while tablet weights and feeder practice are detailed on the TCCA tablets page. Buyers ready to move from specification to supply terms can go directly to the TCCA granular supplier page for MOQ, lead time and export documentation details.
Applications of TCCA Granular
As the most widely traded form of trichloroisocyanuric acid, trichloroisocyanuric acid granular serves every market where controlled-rate dosing and UV-stable chlorine matter: outdoor pool shock and maintenance programs in sun-belt resort regions; drinking-water pretreatment in municipal and rural systems that feed granular through dissolving chambers; aquaculture pond disinfection between production cycles; industrial cooling-water biocide programs; and emergency bulk stock for humanitarian agencies. The 24-month shelf life in sealed drums lets distributors hold granular inventory through seasonal demand cycles without chlorine loss.
Quality Assurance and Export Documentation
Every production batch of tcca granular China export material is tested for available chlorine, moisture and granulometry before release, with results recorded on the Certificate of Analysis that travels with the shipment. Drums are UN 2468 certified for class 5.1 IMDG maritime transport, and the document set includes MSDS, COA, Certificate of Origin, commercial invoice, packing list and dangerous goods declaration. Cargo moves principally FOB Qingdao, Tianjin or Shanghai, with the final loading port confirmed by the product and maritime conditions of the moment, and SGS pre-shipment inspection is available on request.

Frequently Asked Questions
Q: Is there a difference between TCCA granular and TCCA granules?
No. The two terms describe the same grade — trichloroisocyanuric acid 90% minimum, 8-30 mesh white granular solid. "Granular" dominates North American trade while "granules" is the common spelling in UK, West African and South Asian tenders; shipping documents carry the full chemical name so either wording reconciles at customs.
Q: What mesh size do you supply?
8-30 mesh, the trade-standard grade for pools, dissolving tanks and dry-feed programs. Special granular sizing outside this band is handled case by case — contact the technical team with your tender requirement before ordering.
Q: Can granular be used alongside tablets?
Yes — many distributors stock both. Granular handles shock dosing and dissolving-tank feeding; tablets handle slow-release erosion feeding. Both share the same 90% specification and UN 2468 drum packaging. Never mix TCCA with calcium hypochlorite or acids in storage or dosing equipment.
Q: How is granular TCCA packed for export?
In UN 2468 certified plastic drums with inner liners, across the full 5, 10, 15, 20, 25, 40, 45 and 50 kg range, with custom drum weights on request. The 25 kg drum is the standard export format, and storage life in the sealed drum is 24 months.
