4407.99.02.63 - Western red alder (Alnus rubra)

This HTS subcategory, 4407.99.02.63, specifically classifies Western red alder (Alnus rubra) lumber that has been sawn or chipped lengthwise, sliced or peeled, and is greater than 6 mm in thickness. This material may have undergone further processing such as planing, sanding, or end-jointing. The key defining characteristic is the species of wood – Western red alder – which is a nonconiferous (hardwood) species.

This classification is distinct from its siblings, such as hickory, pecan, and walnut, by virtue of its species. While all fall under the broader "Other" nonconiferous category within Chapter 4407, the specific designation for Western red alder allows for precise tariff application based on its unique botanical and commercial identity. Unlike the "Other nonconiferous" residual category, this subcategory offers a dedicated entry for this specific, commercially significant hardwood.

As a leaf node, 4407.99.02.63 does not have further subcategories. Therefore, classification within this code relies solely on the accurate identification of the wood as Western red alder and confirmation that it meets the physical requirements of being sawn or chipped lengthwise, sliced or peeled, and exceeding 6 mm in thickness, whether or not further processed. This ensures that import and export duties are applied accurately to this specific type of lumber.
