4403.91.00 - Of oak (Quercus spp.)

This HTS category, 4403.91.00, specifically covers wood in its rough state that is derived from oak species (Quercus spp.). This includes logs, rough lumber, or timber that has not undergone significant processing. The wood may have had its bark or sapwood removed, or it might have been roughly squared, but it is still considered in its primary, unprocessed form.

Distinguishing this classification from its siblings involves recognizing the specific species of wood. While other categories within 4403.9 cover different types of wood such as beech, birch, poplar, and aspen, this particular code is exclusively for oak. The distinction is crucial for accurate tariff application, as different wood species may be subject to varying duties or import regulations.

Within this category, further subdivisions exist to provide more granular classification. The subcategories 4403.91.00.20 ("Of red oak") and 4403.91.00.40 ("Other") allow for a more precise identification of the specific type of oak. This level of detail can be important for trade statistics, origin verification, and specific import requirements that may apply to different oak varieties.
