Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If contains polyurethane modifiers
Polyurethanes have separate subheading even in blends if specifically named.
If pre-molded into basic shapes
Non-cellular plates/sheets of amino-resins classify as semi-finished under 3920.
If agglomerated with mineral fillers >50%
Heavily filled compounds become equipped agglomerated articles.

Import Tips & Compliance
• Distinguish primary pellets from filled compounds via resin content declaration (>95%); use ventilated containers to manage off-gassing; check country-of-origin for potential CVD on Chinese imports

Urea-Formaldehyde Resin Powder
Urea-formaldehyde resin in powdered primary form, produced by condensing urea and formaldehyde, used primarily in wood adhesives and particleboard production. It falls under HTS 3909.10.00.00 as a urea resin in primary form, meeting the 95% monomer content requirement for the named polymer. This thermosetting resin hardens irreversibly upon heating.
Melamine-Urea-Formaldehyde (MUF) Copolymer Resin
A copolymer resin where urea-formaldehyde units predominate over 95% by weight, used in laminated wood panels and molding compounds. Classified under HTS 3909.10.00.00 due to the predominant urea resin content per subheading note (a)(4). It offers enhanced moisture resistance compared to pure urea-formaldehyde.
Thiourea-Formaldehyde Resin Granules
Thiourea-formaldehyde resin in granular primary form, a sulfur analog of urea resins used in specialty adhesives and ion-exchange resins. It qualifies for HTS 3909.10.00.00 as explicitly named thiourea resins in primary forms. Less common than urea types but valued for chemical resistance.
Liquid Urea-Formaldehyde Pre-Condensate Resin
Low-molecular-weight liquid urea-formaldehyde resin (pre-polymer) in primary form for plywood glues, with >95% urea-formaldehyde units. Classified HTS 3909.10.00.00 as primary urea resin before final curing. Adjustable viscosity for spray or roller application in wood bonding.
Low-Formaldehyde Emission Urea Resin
Scavenger-modified urea-formaldehyde resin in primary powder form with reduced free formaldehyde for interior paneling. Still classified under HTS 3909.10.00.00 as the core urea resin meets 95% criteria per subheading note (a)(1). Meets CARB Phase 2 emission standards.
Urea-Resin Textile Finishing Agent Concentrate
Concentrated urea-formaldehyde resin emulsion for crease-resistant textile finishing, >95% active polymer content. HTS 3909.10.00.00 applies as primary urea resin form before textile application. Provides durable press properties to cotton fabrics.
