Last updated: August 2026 dataAcyclic monoamines not covered by the named subheadings — including mono- and triethylamines, diethylamine, and a range of specialty chloroethylamine derivatives — are classified here, with the US schedule further subdividing them across seven 10-digit lines based on chemical structure and CWC control status. China leads US import supply, followed by the Philippines and Germany. Notably, several lines within this heading (2921196110 and 2921196120) cover N,N-dialkyl-2-chloroethylamines and bis(2-chloroethyl)ethylamine, which are CWC-scheduled precursors subject to strict import controls.

Classification turns on the specific compound: diethylamine and its salts go to 2921191110; mono- and triethylamines to 2921191150; certain named specialty compounds (including 3-amino-3-methyl-1-butyne) to 2921193100; N,N-dialkyl-2-chloroethylamines and their protonated salts to 2921196110; bis(2-chloroethyl)ethylamine to 2921196120; and all remaining acyclic monoamines to 2921196195. Providing the CAS number and structural formula to a licensed customs broker is the most reliable way to confirm the correct line.
Lines 2921196110 and 2921196120 cover compounds that are CWC-scheduled chemical weapons precursors. Importers must comply with Commerce Department CWC regulations, including end-use certification and advance notification requirements. These lines are distinct from the general monoamine lines and require a higher level of regulatory diligence before any import transaction is initiated.
