Subheadings
Products classified under HTS 2933.69.60
Melamine (2,4,6-Triamino-1,3,5-triazine)
Melamine is a chemically defined organic compound containing an unfused triazine ring with three amino groups attached, making it a classic example under HTS 2933.69.60. It is widely used as a raw material in resins, plastics, and flame retardants, classified here due to its specific heterocyclic nitrogen structure as per Chapter 29 notes.
Cyanuric Acid (1,3,5-Triazine-2,4,6-triol)
Cyanuric acid features a hydrogenated triazine ring structure with three hydroxyl groups, qualifying as a heterocyclic nitrogen compound under HTS 2933.69.60. It serves as a stabilizer in chlorine bleach for pools and a precursor in herbicides, fitting Chapter 29's scope for separate chemically defined compounds.
Hexahydro-1,3,5-Tris(2-hydroxyethyl)-s-triazine
This compound contains a hydrogenated triazine ring with hydroxyethyl substituents, classified under HTS 2933.69.60 as an 'other' unfused triazine heterocycle. Used as a preservative in cosmetics and metalworking fluids, it exemplifies Chapter 29's coverage of chemically defined nitrogen heterocycles.
1,3,5-Triazine-2,4,6(1H,3H,5H)-trione Monosodium Salt
A sodium salt of cyanuric acid featuring the unfused triazine ring, this falls under HTS 2933.69.60 per Chapter 29 note on inorganic salts of organic compounds classified with the parent. Used in water treatment, it remains a chemically defined heterocyclic compound.
2-Chloro-4,6-bis(isopropylamino)-1,3,5-triazine (Commercial Atrazine Impurity)
This chlorinated triazine derivative with isopropylamino groups is an 'other' compound under HTS 2933.69.60, containing the unfused triazine ring as required. Often an impurity in herbicides or used in synthesis, it fits Chapter 29 for halogenated nitrogen heterocycles.
Triethylenemelamine (TEM)
Triethylenemelamine contains a triazine ring in its ethylenimine trimer structure, classified as an 'other' unfused triazine under HTS 2933.69.60. Historically used in chemotherapy, it exemplifies Chapter 29's coverage of nitrogen heterocycles with therapeutic potential akin to heading 2937 hormones.
