Wood Fiber Acoustic Ceiling Tiles
Perforated fiberboard panels (0.35-0.5 g/cm³ density) designed for sound absorption in suspended ceilings, made from agglomerated wood fibers. Classified under HTS 4411.94.00.40 as low-density 'other' fiberboard. Perforations and fissures enhance acoustic properties for office/commercial use.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If manufactured as medium board density range
Narrower 'medium board' spec within same density if producer designates as such.
If articles with ≥97% magnesite/cement
Mineral-bound boards classify as cement articles, not wood fiberboard.
If pre-painted or edge-finished for direct installation
Assembled cellular wood panels for construction shift to 4418.40.

Import Tips & Compliance
• Include acoustic performance test data and density certification in entry documents
• Distinguish from mineral fiber tiles (6811) by emphasizing wood fiber composition
• Avoid classification as finished 'panels' (4418) by documenting as raw acoustic substrate material

Bagasse Fiberboard Wall Sheathing
Fiberboard made from sugarcane bagasse (ligneous agricultural residue), density 0.35-0.5 g/cm³ for exterior wall sheathing. HTS 4411.94.00.40 includes non-wood ligneous materials as other low-density fiberboard. Eco-friendly structural sheathing board.
Low-Density Particleboard Insulation Panels
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.
