Import Tips & Compliance
• Submit lab density measurements; naming as 'HDF' risks scrutiny for 4411.92 classification
• Include moisture content specs and TSCA certification for floor underlayment
• Declare if tongue-and-groove edged, but remains fiberboard unless assembled

MDF Insulation Board 6mm
Medium-density fiberboard with a density of 0.45 g/cm³, made from wood fibers bonded with resins, used primarily for sound and thermal insulation in walls. It falls under HTS 4411.94.00 due to its low density not exceeding 0.5 g/cm³ and classification as fiberboard of wood. This lightweight material is ideal for construction applications requiring minimal weight.
Low-Density Particleboard 9mm
Particleboard made from wood particles with a density of 0.42 g/cm³, bonded with urea-formaldehyde resin, used for lightweight furniture cores. Classified under HTS 4411.94.00 as fiberboard (including particleboard) of density not exceeding 0.5 g/cm³. Its low weight makes it suitable for non-structural applications.
