U.S. exports of amino-resins (non-enumerated), primary forms (HS 390939) totaled $3.9M in August 2026.
Importers of Amino-Resins (Non-Enumerated), Primary Forms paid $130K in duties in August 2026, an effective tariff rate of 13.28% of the $978K imported — duty actually collected as a share of that value, not the published tariff schedule. Amino-Resins (Non-Enumerated), Primary Forms imports of $978K in August 2026 ran 13% above the year-to-date monthly average of $867K.
Last updated: August 2026 dataAmino-resins not elsewhere specified — covering formulations beyond urea, thiourea, and melamine types — include specialty crosslinkers, glycoluril-based resins, and modified amino compounds used in coatings, textile finishing, and paper treatment. All US imports are classified under a single 10-digit line (3909390000). France leads supply under this heading, followed by Taiwan and Canada, a supplier mix that reflects both European specialty chemical production and Asian coating-resin manufacturing.

This residual line captures amino-resins whose base amino compound is neither urea/thiourea nor melamine — for example, benzoguanamine-formaldehyde resins used in high-durability coatings, glycoluril-based resins used as crosslinkers in semiconductor photoresists, and aniline-formaldehyde condensates. If the predominant amino component is urea or melamine, classification shifts to 3909.10 or 3909.20 respectively.
Classification of blended amino-resins depends on the predominant amino-compound character of the mixture. If melamine is the primary reactive component, 3909.20 is likely correct; if benzoguanamine or another non-enumerated amino compound predominates, 3909390000 applies. A licensed customs broker and a detailed technical specification from the manufacturer are essential for making this determination.
