4407.19.00.64 - Rough

This HTS category, 4407.19.00.64, specifically classifies rough, sawn or chipped lengthwise, sliced or peeled timber of coniferous species, exceeding 6 mm in thickness. The "rough" designation indicates that the wood has not undergone further processing such as planing, sanding, or end-joining. This category captures coniferous woods that do not fit into more specific subcategories within the broader classification of coniferous wood.

The key differentiator for this subcategory lies in its exclusion from more specific types of coniferous wood, such as Douglas fir, fir, and spruce, which are typically classified under separate HTS codes. Furthermore, this code applies to wood that has not been treated or further finished. The distinction is crucial for accurate duty assessment and trade statistics, ensuring that generalized coniferous timber is correctly identified.

As a leaf node, this category does not have further subcategories. Therefore, classification within 4407.19.00.64 hinges on the wood being coniferous, exceeding 6 mm in thickness, and remaining in its rough, unfinished state, without falling under more granular classifications for specific coniferous species or treatments. For example, hemlock (Tsuga spp.) timber that meets these general criteria would be classified here.
