4412.33 - Other, with at least one outer ply of nonconiferous wood of the species alder (Alnus spp.), ash (Fraxinus spp.), beech (Fagus spp.), birch (Betula spp.), cherry (Prunus spp.), chestnut (Castanea spp.), elm (Ulmus spp.), eucalyptus (Eucalyptus spp.), hickory (Carya spp.), horse chestnut (Aesculus spp.), lime (Tilia spp.), maple (Acer spp.), oak (Quercus spp.), plane tree (Platanus spp.), poplar and aspen (Populus spp.), robinia (Robinia spp.), tulipwood (Liriodendron spp.) or walnut (Juglans spp.):

This HTS category, 4412.33, specifically classifies plywood and similar laminated wood products where at least one outer ply is made from a defined list of nonconiferous wood species. These species include commonly recognized hardwoods such as oak, maple, beech, birch, and walnut, as well as others like alder, ash, and eucalyptus. The defining characteristic is the origin of the outer veneer from these specified nonconiferous trees, each ply not exceeding 6 mm in thickness, and the material is not bamboo.

Subheading 4412.33 is distinct from its siblings. It differs from 4412.31, which specifically covers plywood with at least one outer ply of tropical wood. It is also differentiated from 4412.34, which encompasses other plywood with nonconiferous wood outer plies *not* listed in the species for 4412.33. Furthermore, it stands apart from 4412.39, which is designated for plywood where both outer plies are exclusively of coniferous wood.

Within 4412.33, further subdivisions exist to refine the classification based on surface treatment. The primary distinction is between panels that are not surface-covered or are covered with a clear or transparent material that still allows the grain and texture of the face ply to be visible, and other finished products, as exemplified by the further subheading 4412.33.57.00. This segregation acknowledges differences in the final presentation and potential end-uses of the laminated wood.
