U.S. imports of Cyclanic, Cyclenic, and Cycloterpenoid Mono- and Polyamines (HS 292130) totaled $5.0M in September 2026, imported from 16 countries.
Importers of Cyclanic, Cyclenic, and Cycloterpenoid Mono- and Polyamines paid $630K in duties in September 2026, an average duty rate of 12.52% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule.
Last updated: September 2026 dataCycloaliphatic amines — including the specifically enumerated 1,3-bis(aminoethyl)cyclohexane (2921300500) — are valued as low-color, low-volatility curing agents for high-performance epoxy systems used in flooring, marine coatings, and wind-energy composites. The US schedule further distinguishes cyclanic amines derived from aromatic compounds (2921301000, 2921303000) from those that are not (2921305000), a processing-origin distinction that can affect both classification and duty rate. Czech Republic and Germany are the leading suppliers, reflecting European specialty chemical capacity in this niche segment.

The distinction tracks the chemical manufacturing route: amines derived from aromatic intermediates may carry different duty rates and are subject to separate US note provisions (US Note 3 to Section VI). Importers must obtain documentation from the manufacturer confirming the synthetic pathway to support the correct tariff line selection.
A manufacturer's certificate of analysis confirming the CAS number and structural identity, combined with a technical data sheet describing the synthesis route, is typically sufficient to support classification under 2921300500. For ambiguous cases, a CBP binding ruling provides certainty.
