Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If non-cellular rigid polyurethane
Non-cellular polyurethane plates/sheets fall under other non-cellular plastics in 3921.90.
If laminated with wood fibers as particleboard
Wood-based panels with plastic facing shift to Chapter 44 for densified wood materials.
If containing plasticizers over specified limits
Subheading notes define plasticizers for 3920.43; may apply if insulation has additives predominating.
