HS Code 3909.39 – Amino-resins; n.e.c. in heading no. 3909, in primary forms, other than poly(methylene phenyl isocyanate) (Crude MDI, polymeric MDI)
HS code 3909.39 is the 6-digit subheading for amino-resins, n.e.c. in heading no. 3909, in primary forms, other than poly(methylene phenyl isocyanate) (Crude MDI, polymeric MDI). It is used for urea-formaldehyde resins, melamine-formaldehyde resins, benzoguanamine resins, aniline-formaldehyde resins and polyamine resins.
What HS 3909.39 covers
This HS code encompasses a broad range of amino-resins in primary forms, excluding the specific poly(methylene phenyl isocyanate) covered by 390931. This category includes crucial polymers like urea-formaldehyde (UF) resins and melamine-formaldehyde (MF) resins, which are traded as liquids, powders, or granules. These resins are indispensable for manufacturing laminates, particleboard, plywood, adhesives, coatings, and molding compounds. Importers are typically manufacturers in the furniture, construction, automotive, and electrical industries, seeking durable, heat-resistant, and cost-effective binding and surfacing materials. Exporters are often large chemical companies. The global trade in these amino-resins is significant, driven by their widespread use in composite wood products and high-pressure laminates, making them a staple in various industrial supply chains.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
