U.S. imports of amino-resins (non-enumerated), primary forms (HS 390939) totaled $1.1M in June 2026, traded with 17 countries.
Importers of Amino-Resins (Non-Enumerated), Primary Forms paid $166K in duties in June 2026 — an effective duty rate of 16% on $1.1M in dutiable value, based on actual customs collections rather than the published tariff schedule. Amino-Resins (Non-Enumerated), Primary Forms imports of $1.1M in June 2026 ran 49% above the year-to-date monthly average of $744K.
Amino-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.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
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.
