Dimethylamine Anhydrous
Anhydrous dimethylamine is the pure gaseous form of dimethylamine, a simple acyclic monoamine. It is a separate chemically defined organic compound of heading 29.21, and being anhydrous, it contains no added solvent or stabilizer. It is directly classifiable under tariff item 2921.11.00 as dimethylamine.
2921.11.00Dimethylamine Hydrochloride
Dimethylamine hydrochloride is the salt of dimethylamine, formed by reacting dimethylamine with hydrochloric acid. As a salt of a simple acyclic monoamine, it is classifiable under heading 29.21, and specifically under tariff item 2921.11.00 as a salt of dimethylamine. It is a chemically defined organic compound used as an intermediate in the production of surfactants, rubber accelerators, and herbicides.
2921.11.00Dimethylamine Sulfate
Dimethylamine sulfate is a salt of dimethylamine with sulfuric acid, used in dye intermediates and as a stabilizer. As a salt of a simple acyclic monoamine, it falls under heading 29.21 and specifically under tariff item 2921.11.00 as a salt of dimethylamine. The presence of the sulfate anion does not change the classification, as inorganic salts of organic bases are classified with the organic compound.
2921.11.00Methylamine (40% Aqueous Solution)
Methylamine 40% in water is a standard aqueous solution of methylamine, a simple acyclic monoamine. Under Chapter Note 1(d) of Chapter 29, products of heading 29.21 dissolved in water are classifiable in the chapter. Therefore, this solution falls under tariff item 2921.11.00 as methylamine, provided the water is the only solvent and the solution is a normal method of transport.
2921.11.00Methylamine Stabilized with Ammonia
Methylamine stabilized with ammonia is a solution of methylamine containing ammonia as a stabilizer to prevent corrosion during transport. Under Chapter Note 1(f) of Chapter 29, products of heading 29.21 with an added stabilizer necessary for preservation or transport are classifiable in the chapter. Therefore, this product falls under tariff item 2921.11.00 as methylamine, provided the ammonia does not render it particularly suitable for a specific use.
2921.11.00Methylammonium Chloride
Methylammonium chloride, also known as monomethylamine hydrochloride, is the salt of methylamine with hydrochloric acid. As a salt of a simple acyclic monoamine, it falls under heading 29.21 and specifically under tariff item 2921.11.00 as a salt of methylamine. It is a chemically defined organic compound used in the production of perovskite solar cells and other applications.
2921.11.00Monomethylamine Hydrochloride
Monomethylamine hydrochloride is the salt form of methylamine, a simple acyclic monoamine. It is a chemically defined organic compound used primarily in organic synthesis for pharmaceuticals and agrochemicals. As a salt of methylamine, it falls under tariff item 2921.11.00, consistent with Chapter Note 5(C)(1) which classifies inorganic salts of organic bases with the organic compound.
2921.11.00Trimethylamine 25% in Water
Trimethylamine 25% in water is an aqueous solution of trimethylamine, a simple acyclic monoamine. Under Chapter Note 1(d) of Chapter 29, products of heading 29.21 dissolved in water are classifiable in the chapter. Therefore, this solution falls under tariff item 2921.11.00 as trimethylamine, provided the water is the only solvent and the solution is a normal method of transport.
2921.11.00Trimethylamine Hydrochloride
Trimethylamine hydrochloride is the crystalline salt of trimethylamine, a simple acyclic monoamine. It is a chemically defined organic compound used in choline synthesis for animal feed additives and pharmaceuticals. As a salt of trimethylamine, it falls under tariff item 2921.11.00, consistent with Chapter Note 5(C)(1) which classifies inorganic salts of organic bases with the organic compound.
