Sodium Dichloroisocyanurate SDIC Tablets, CAS 2893-78-9, Available Chlorine Grades for Export Sourcing
Buyer-facing sourcing candidate for sodium dichloroisocyanurate (SDIC) tablets from China, focused on CAS verification, available chlorine grade, moisture, pH, tablet size, packing, export documents, and dangerous goods shipment checks. The source page headline states 84.0% min available chlorine, while the extracted specification table lists SDIC grades around 56%, 60%, and hydrated material around 55%, so grade confirmation is required before RFQ or listing approval.

Public facility sanitation product sourcing subject to destination-market registration
General chlorinated water-treatment chemical procurement with DG shipment review
How we compare
Sourcing options
Request an RFQ for SDIC anhydrous tablets with confirmed CAS 2893-78-9 and 56%-60% available chlorine if matching the source table.
Request a separate RFQ for SDIC dihydrate with CAS 51580-86-0 and moisture 10%-14% if hydrated grade is intended.
Ask supplier to quote by tablet weight, available chlorine specification, package type, and destination port.
Compare against TCCA or other chlorinated isocyanurates only after confirming CAS, UN number, available chlorine, and regulatory acceptability.
Source only from suppliers able to provide SDS, COA, export DG documents, and consistent product labeling.
Human review
Compliance notes
Treat as a compliance-sensitive oxidizing/disinfectant chemical candidate requiring CAS, grade, SDS, COA, UN number, packing group, and destination-country import checks before sourcing.
Source table lists UN No. 2465 and 3077; confirm the correct UN classification for the exact SDIC grade, hydration state, available chlorine level, and packaging configuration.
Do not rely on the source page title alone for available chlorine because headline and table specifications conflict.
Request current SDS aligned with GHS/CLP format and transport section details for sea and air shipment review.
Request batch COA showing available chlorine, moisture, pH, appearance, tablet size or weight, and insoluble matter if applicable.
Supplier mentions commercial invoice, packing list, bill of lading, insurance, COA, and certificate of origin; confirm whether SDS, DG declaration, and any inspection certificates are available.
Confirm whether SGS, BV, or ISO references apply to the manufacturer, product batch, or management system only.
Buyer must verify local registration, import permit, biocide/disinfectant rules, water-treatment approvals, and labeling requirements in the destination market.
