Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If pre-shaped for flooring
Profiled or tongued/grooved panels become construction joinery.
If low density version
Sub-0.5 g/cm³ density fiberboard has separate statistical breakout.
If reinforced with glass fibers
Articles with glass fiber reinforcement classify under Chapter 68.

Import Tips & Compliance
• Include end-use statements confirming industrial substrate purpose, not finished flooring
• Monitor moisture content <10% to prevent warping claims during transit
• Avoid plastic wrapping directly on surface; use spacers to prevent adhesion issues
