U.S. exports of Acyclic Polyamines & Their Derivatives and Salts (SITC 51452) totaled $69.5M in August 2026.
Importers of Acyclic Polyamines & Their Derivatives and Salts paid $2.1M in duties in August 2026, an average duty rate of 9.76% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Acyclic Polyamines & Their Derivatives and Salts imports of $21.6M in August 2026 ran 54% above the year-to-date monthly average of $14.1M.
Last updated: August 2026 dataAcyclic polyamines — open-chain molecules with two or more amine groups — are indispensable curing agents for epoxy resins, chelating agents in industrial water treatment, and precursors to polyamide resins used in adhesives and coatings. Ethylenediamine (EDA) and diethylenetriamine (DETA) are among the most widely traded members of this group. Supply chains for these chemicals are globally concentrated, and any Section 301 exposure on Chinese-origin polyamines can materially affect formulation costs for downstream manufacturers.

The critical distinction is the number of amine functional groups: monoamines carry one, while polyamines carry two or more on an open-chain carbon backbone. A compound like ethylenediamine (two amine groups, no ring) belongs in the polyamine heading, whereas methylamine (one amine group) falls under monoamines. Misidentifying the amine count is a common classification error.
Not necessarily. EDTA and similar aminopolycarboxylic acid chelating agents carry additional oxygen functions (carboxylate groups) that may place them under a different, more specific SITC or HTS heading. Classification should be confirmed based on the full functional-group profile of the specific compound.
