Products classified under HTS 3909.50.20.00
Polyurethane Construction Adhesive
A moisture-curing polyurethane cement designed for bonding wood, concrete, and metal in construction applications. Classified under HTS 3909.50.2000 as it is a polyurethane-based cement in primary form, where polyurethane monomers constitute 95% or more by weight per chapter notes. Primarily used for structural bonding rather than bulk polymer resin.
Polyurethane Woodworking Glue
One-component polyurethane cement for gap-filling wood joints, expanding on curing for strong bonds in furniture making. Falls under 3909.50.2000 as polyurethane cement in primary form with ≥95% polyurethane content. Distinguished from prepared glues by lack of extensive formulation.
Polyurethane Concrete Bonding Cement
High-strength polyurethane cement for anchoring rebar and bonding new concrete to old surfaces in civil engineering. HTS 3909.50.2000 applies to this primary-form polyurethane cement meeting 95% monomer purity. Used in bulk for mixing on-site.
Polyurethane Foam Adhesive Cement
Expanding polyurethane cement for insulating foam board installation and gap filling in building envelopes. Classified in 3909.50.2000 as polyurethane cement in primary form, with predominant polyurethane monomers. Supplied in bulk drums for professional use.
Industrial Polyurethane Laminating Cement
Two-part polyurethane cement for laminating films to substrates in flexible packaging production. HTS 3909.50.2000 covers this primary polyurethane resin cement with ≥95% qualifying monomers. Used in high-speed industrial coaters.
Polyurethane Shoe Sole Cement
Contact polyurethane cement for bonding rubber soles to leather uppers in footwear manufacturing. Falls under 3909.50.2000 as primary-form polyurethane cement per 95% monomer rule in chapter notes. Bulk-supplied for factory dipping.
Marine Polyurethane Deck Cement
Water-resistant polyurethane cement for teak deck caulking and bonding on boats and ships. Classified 3909.50.2000 as polyurethane cement in primary form meeting polymer purity standards. Professional marine-grade formulation.
Polyurethane Panel Bonding Cement
Structural polyurethane cement for bonding wall panels, countertops, and laminates in prefab construction. HTS 3909.50.2000 for primary polyurethane cements with qualifying monomer composition. High-modulus for load-bearing joints.
Polyurethane Carpet Backing Cement
Reactive polyurethane cement for laminating carpet backing to primary tufting fabric in textile mills. Under 3909.50.2000 as primary-form polyurethane cement per chapter polymer classification rules. Roll-applied in manufacturing.
Polyurethane Windshield Adhesive Cement
Fast-curing polyurethane cement for automotive glass replacement and windshield bonding. HTS 3909.50.2000 applies to this primary polyurethane cement formulation. Supplied in bulk for auto body shops.
