Import Tips

Verify chemical purity and ensure COA (Certificate of Analysis) matches HTS classification as halogenated derivative of heading 2912

Comply with EPA TSCA registration for disinfectants; include SDS and proper UN packaging for hazardous goods

Avoid misclassification as simple bleaching agents (heading 2828); confirm cyanuric acid base structure
