HS code for Dimethylamine: 2921.11

Amine-function compounds, acyclic monoamines and their derivatives, methylamine, di- or trimethylamine and their salts.

Classification of dimethylamine under HS 2921.11

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.

Codes often confused with 2921.11

Common mistake. 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.

Top exporters and importers of HS 292111 (the code used for dimethylamine), 2025

In 2025, the largest exporter of HS 292111 (the code used for dimethylamine) in UN Comtrade data was Belgium, with 26% of world exports; the largest importer in UN Comtrade data was India, with 16% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

How these figures are built

109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
