Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If medium density fiberboard (MDF) construction
Fiber-based boards 0.5-0.8 g/cm³ density classify under 4411, unlike OSB's visible strand structure.
If with factory-applied cementitious coating
Mineral-coated wood panels for exterior use shift to Chapter 68 as coated construction materials.
If non-coniferous wood species like poplar
Subheading 4410.21 specifically covers OSB from non-coniferous woods, separated from general coniferous OSB.
