Low-Density Particleboard Insulation Panels from Japan
These fiberboard panels, made from wood particles bonded with resins, have a density between 0.35 and 0.5 g/cm³, classifying them under HTS 4411.94.00.40 as low-density fiberboard other than medium board. They are commonly used for wall insulation and soundproofing in construction. The specific density range distinguishes them from higher-density MDF or HDF products.

Import Tips
• Obtain mill test certificates verifying density between 0.35-0.5 g/cm³ to avoid reclassification to higher density subheadings
• Ensure documentation specifies 'other' fiberboard not qualifying as lauan/mixed heartwood to prevent misclassification
