4407.91.00.63 - Other

This HTS category, 4407.91.00.63, covers lumber and timber that has been sawn or chipped lengthwise, sliced, or peeled, and has a thickness exceeding 6 mm. Crucially, this wood has undergone further processing beyond basic milling, including planing, sanding, or end-jointing. The "Other" designation within this subcategory indicates that it captures wood not specifically accounted for in prior headings at this level.

Distinguished from its sibling category, 4407.91.00.22 "Red oak," this classification applies to lumber of oak (Quercus spp.) that does not meet the specific criteria for red oak. While both fall under "Of oak (Quercus spp.)" and share the general characteristics of sawn or chipped timber over 6mm thick, the distinction lies in the specific species or variety of oak. This category serves as a catch-all for oak lumber that isn't explicitly classified as red oak within the tariff schedule.

As this is a leaf node, there are no further subcategories to introduce. Therefore, classification within 4407.91.00.63 relies on confirming that the wood is indeed oak (Quercus spp.), has a thickness exceeding 6 mm, has been sawn, chipped, sliced, or peeled, and has been planed, sanded, or end-jointed, while not being classifiable as red oak. This ensures accurate identification of processed oak lumber not otherwise specified.
