Products classified under Tariff item 3909.10.00.00
High-Purity Urea Resin for Foundry Binders
High-purity urea-formaldehyde resin powder used as a binder in foundry core systems. It is in primary form, meeting the 95% monomer rule for classification as a urea resin under this tariff item.
3909.10.00Liquid Urea-Formaldehyde Pre-Condensate Resin
Liquid urea-formaldehyde pre-condensate resin in primary form, used as an adhesive for plywood. It is a low-molecular-weight prepolymer with over 95% urea-formaldehyde units, fitting the urea resin classification.
3909.10.00Low-Formaldehyde Emission Urea Resin
Scavenger-modified urea-formaldehyde resin powder with reduced free formaldehyde, used for interior paneling. The core urea resin exceeds 95% content, and the modification does not alter its classification as a urea resin in primary form.
3909.10.00Melamine-Urea-Formaldehyde (MUF) Copolymer Resin
Melamine-urea-formaldehyde copolymer resin where urea-formaldehyde units predominate by over 95% by weight, used in laminated wood panels. It is classified as a urea resin under the subheading note's monomer predominance rule.
3909.10.00Spray-Dried Urea Formaldehyde Microcapsules
Spray-dried urea-formaldehyde resin microcapsules in primary powder form, used for controlled-release applications. The polymer shell is chemically unmodified and exceeds 95% urea-formaldehyde content, fitting the urea resin classification.
3909.10.00Thiourea-Formaldehyde Resin Granules
Thiourea-formaldehyde resin granules in primary form, a sulfur analog of urea resins used in specialty adhesives. It is explicitly named in the tariff item as a thiourea resin, qualifying for classification here.
3909.10.00Urea-Formaldehyde Resin Powder
Urea-formaldehyde resin powder produced by condensing urea and formaldehyde, used in wood adhesives and particleboard production. It is a primary-form urea resin with over 95% polymer content, fitting this tariff item.
3909.10.00Urea-Resin Molding Compound Pellets
Pelletized urea-formaldehyde resin in primary form for compression molding of electrical insulators and dinnerware. It is an unmodified urea resin exceeding 95% polymer content, classified under this tariff item.
3909.10.00Urea-Resin Textile Finishing Agent Concentrate
Concentrated urea-formaldehyde resin emulsion for crease-resistant textile finishing, with over 95% active polymer content. It is in primary form as a liquid dispersion, fitting the urea resin classification.
3909.10.00Urea-Thiourea Copolymer Resin
Urea-thiourea copolymer resin where urea units predominate over thiourea, used in paper impregnation. It is classified as a urea resin under the subheading note's monomer predominance rule, with combined urea and thiourea units exceeding 95%.
