2933.69.50.00 - Hexamethylenetetramine

This classification pertains to hexamethylenetetramine, a synthetic organic compound widely utilized in various industrial applications. Its primary role is as a cross-linking agent and hardener in the production of resins, particularly phenolic resins, which are essential for manufacturing molded articles, abrasives, and adhesives. Hexamethylenetetramine also finds use as a fuel tablet due to its high energy density and clean burn characteristics, and in the synthesis of other chemical compounds.

Within the broader category of compounds containing an unfused triazine ring, this specific classification distinguishes itself from its sibling category 2933.69.20.00, which covers 2,4-diamino-6-phenyl-1,3,5-triazine. The key difference lies in the molecular structure: hexamethylenetetramine features a cage-like bicyclic structure formed by the condensation of formaldehyde and ammonia, whereas 2,4-diamino-6-phenyl-1,3,5-triazine contains a distinct, planar triazine ring substituted with amino and phenyl groups.

As a leaf node, HTS code 2933.69.50.00 does not have further subcategories. Therefore, classification within this code is determined by the specific identification of hexamethylenetetramine itself, based on its chemical composition and purity. Importers and exporters should ensure accurate documentation confirming the identity of the substance to comply with customs regulations.
