HS Code for Dimethylamine

Dimethylamine is classified under HS code 2921.11. This classification is part of Chapter 29, which covers organic chemicals. Heading 2921 is dedicated to amine-function compounds, which are organic derivatives of ammonia. Subheading 2921.11 is a specific, named category for methylamine, dimethylamine, or trimethylamine, and their salts. Dimethylamine ((CH3)2NH) is a secondary acyclic monoamine. The classification is straightforward because the Harmonized System provides a specific line item for this chemical due to its high volume in global trade and its role as a precursor in various industrial processes, including the production of surfactants, pesticides, and pharmaceuticals. As a pure chemical compound of known molecular structure, it must be classified in Chapter 29 rather than in chemical preparations or mixtures found in later chapters.

Products Included

• Anhydrous dimethylamine gas
• Dimethylamine in aqueous solution
• Dimethylamine hydrochloride (as a salt)
• Dimethylamine sulfate
• Technical grade dimethylamine

Common Misclassification

Dimethylamine is sometimes misclassified under 2921.19, which is the "other" category for acyclic monoamines. However, because dimethylamine is explicitly named in 2921.11, the use of the residual code 2921.19 is incorrect. Another error involves classifying aqueous solutions under Chapter 38 (Miscellaneous chemical products); however, Note 1 to Chapter 29 allows for products dissolved in water to remain within Chapter 29. It should also not be confused with dimethylformamide (DMF), which is an amide classified under 2924.19.
