Isothiazolinone Biocide CMIT/MIT for Industrial Water Treatment - CAS 26172-55-4 / 2682-20-4
Industrial isothiazolinone biocide candidate for overseas buyers requiring CAS-level verification of CMIT/MIT content, grade, concentration, impurity profile, packing, and export documentation. This item is positioned for industrial circulating water, cooling tower, oilfield injection water, and related water-treatment applications, not for food preservative sourcing. Buyers should request SDS, COA, composition disclosure, transport classification, and destination-market compliance checks before RFQ confirmation.

Compliance notes
Not suitable as a food preservative candidate; source application is industrial water treatment
Request current SDS in English and destination-market language if required
Request COA showing active content, CMIT/MIT ratio, pH, density, appearance, and relevant impurity limits
Confirm dangerous goods classification, UN number, packing group, hazard class, marine pollutant status, and transport mode restrictions for the exact concentration
Check India import requirements before ordering, including chemical inventory, customs classification, labeling, and any biocide or industrial chemical registration obligations
Do not rely on marketplace claims as regulatory approval; obtain supplier declarations and third-party test reports where needed
Confirm whether preservatives, stabilizers, salts, or solvents are present and whether any impurities are restricted in the buyer’s jurisdiction
For sensitive end uses, request non-food-use declaration and written confirmation that the product is industrial grade only
