Medium Density Fiberboard Underlayment Sheets
MDF sheets with density 0.35-0.5 g/cm³ used as flooring underlayment, produced by bonding wood fibers with resins under heat and pressure. Falls under HTS 4411.94.00.40 as low-density fiberboard 'other' category. Ideal for subflooring due to uniform structure and moisture resistance.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If density ≤0.5 g/cm³ but from lauan/meranti
Tropical hardwood sourcing triggers specific 4411.93 classification regardless of density.
If plywood-type laminated construction
If constructed as layered plywood panels rather than molded fiberboard, moves to Chapter 4412.
If prefinished with laminate surface
Surface-covered floor coverings classify under 4418, not raw fiberboard.

Import Tips & Compliance
• Label shipments clearly as 'density 0.35-0.5 g/cm³ fiberboard' and include lab density reports
• Verify no tropical wood content to stay in 'other' subheading; declare species origins accurately
