4407.91.00 - Of oak (Quercus spp.)

This HTS classification, 4407.91.00, specifically covers wood that has been sawn or chipped lengthwise, sliced or peeled, and measures over 6 mm in thickness. This category encompasses such wood that is also whether or not planed, sanded, or end-jointed. The defining characteristic of this particular sub-heading is that the wood is of oak (Quercus spp.).

Distinguishing this classification from its siblings is the precise species of wood. While other categories within 4407.91 cover woods like beech, maple, cherry, ash, and birch, this sub-heading is exclusively for oak. This highlights the importance of species identification for accurate tariff classification, as different wood species may have different duties or import regulations.

Within this classification, further subdivisions exist to provide more granular detail. The subcategories 4407.91.00.22 for "Red oak" and 4407.91.00.63 for "Other" allow for a more precise categorization based on specific types of oak, which can be crucial for trade statistics and for applying specific trade measures that might apply to different oak varieties.
