Cyanuric Chloride Flake Form from Mexico

Cyanuric chloride in flake form is the solid crystalline version of this triazine compound, used primarily as a reagent in reactive dye production. It qualifies under HTS 2933.69.60.10 per chapter note (a) as a separate chemically defined organic compound with triazine structure. The flake physical form aids handling but does not alter chemical classification.
