Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If assembled into preformed acoustic panels for buildings
Pre-fabricated building panels with working parts classify under 4418.40, not raw fiberboard.
If mineral fibers added for enhanced insulation
Mixed mineral/wood fiber products treated as mineral materials under Chapter 68.
If particle-based rather than true fiberboard
Larger wood particles classify as particle board (4410), distinct from fiberboard process.

Import Tips & Compliance
• Test and document porosity/density for acoustic claims; CBP may require proof it's not rigid insulation
• Ensure no perforations or fabric facing, which could shift to 4418 joinery or 7019 glass wool analogs
• Fire rating documentation helpful for building code compliance in US imports
