4407.97.00.79 - Other poplar; aspen; cottonwood

This HTS category, 4407.97.00.79, encompasses wood that has been sawn or chipped lengthwise, sliced, or peeled, and which exceeds 6 mm in thickness. Specifically, it covers wood from species identified as "other poplar," "aspen," and "cottonwood." This designation is crucial for customs purposes, differentiating these timber products from other wood types that may undergo similar processing. The wood in this classification may also have been further treated by planing, sanding, or end-jointing.

The key distinction within this level lies in the botanical identification of the wood. While sibling category 4407.97.00.72 specifically covers "Yellow poplar" (botanically *Liriodendron tulipifera*), this category is reserved for woods belonging to the *Populus* genus, commonly known as poplar, aspen, and cottonwood, which are distinct from yellow poplar. Therefore, accurate identification of the timber species is paramount for correct classification.

As this is a leaf node, there are no further subcategories within 4407.97.00.79. This means that all wood meeting the criteria of sawn, chipped, sliced, or peeled timber exceeding 6 mm in thickness, originating from species classified as other poplar, aspen, or cottonwood, will be classified under this specific code, provided it is not yellow poplar. The classification hinges on the species identification of the raw timber material.
