HS Code for Methylamine

Methylamine, along with its derivatives dimethylamine and trimethylamine, is classified under HS code 2921.11. This classification is found in Chapter 29, which covers organic chemicals, and heading 2921, which is dedicated to amine-function compounds. Subheading 2921.11 specifically covers acyclic monoamines including methylamine, di- or trimethylamine, and their salts. These chemicals are basic organic compounds where one or more hydrogen atoms in ammonia are replaced by methyl groups. The classification includes these substances in their anhydrous form or in aqueous solutions, as well as their various salts, such as methylamine hydrochloride. These compounds are essential building blocks in the synthesis of pharmaceuticals, pesticides, and surfactants.

Products Included

• Anhydrous methylamine
• Methylamine in aqueous solution
• Dimethylamine
• Trimethylamine
• Methylamine hydrochloride and other salts

Common Misclassification

Methylamine is sometimes misclassified under HS code 2921.19, which is the residual category for other acyclic monoamines. However, because methylamine and its methyl-derivatives are explicitly named in 2921.11, that code must be used. It can also be confused with amino-alcohols like ethanolamine, which are classified under heading 2922.

FAQ

What is the HS code for methylamine?

The HS code for methylamine, dimethylamine, and trimethylamine, including their salts, is 2921.11.

Are aqueous solutions of methylamine classified differently?

No, aqueous solutions of these amines are classified under the same HS code (2921.11) as the anhydrous forms, provided they are not mixed with other substances that change their character.
