Monomethylamine Hydrochloride
Monomethylamine hydrochloride is the salt form of methylamine, a simple acyclic monoamine, used primarily in organic synthesis for pharmaceuticals and agrochemicals. It falls under HTS 2921.11.00.00 as a salt of methylamine, explicitly covered by the heading for methylamine, di- or trimethylamine and their salts. This chemically defined compound meets Chapter 29 note (a) for separate organic compounds.
Dimethylamine Hydrochloride
Dimethylamine hydrochloride, a salt of dimethylamine, serves as a key intermediate in producing surfactants, rubber accelerators, and herbicides. Classified under HTS 2921.11.00.00 due to its status as a di-methylamine salt, fitting the precise heading description. It qualifies as a separate chemically defined organic compound under Chapter 29.
Trimethylamine Hydrochloride
Trimethylamine hydrochloride is the crystalline salt of trimethylamine, widely used in choline synthesis for animal feed additives and pharmaceuticals. It is squarely under HTS 2921.11.00.00 as a trimethylamine salt, a chemically defined acyclic monoamine derivative. Chapter notes confirm inclusion of salts without exclusions applying.
Methylamine (40% Aqueous Solution)
Methylamine 40% in water is a standard transport form of methylamine, used in epoxy resin curing and dye manufacturing. Allowed under HTS 2921.11.00.00 per Chapter note (d) for products of (a) dissolved in water. Remains classified as the pure compound if meeting safety/transport criteria.
Dimethylamine Anhydrous
Anhydrous dimethylamine is the pure gaseous form compressed for transport, essential for solvent and propellant production. Directly classifiable under HTS 2921.11.00.00 as di-methylamine, a separate acyclic monoamine per Chapter 29 note (a). No exclusions apply to this base compound.
Trimethylamine 25% in Water
Trimethylamine 25% aqueous solution, stabilized for safe shipping, used in natural flavor synthesis and wastewater treatment. Covered by HTS 2921.11.00.00 under Chapter note (d) as trimethylamine dissolved in water for transport. Qualifies as the amine compound, not a preparation.
