4407.12.00.19 - Rough

This HTS category, 4407.12.00.19, encompasses rough-sawn or chipped lumber, sliced or peeled veneer, and wood that is otherwise processed to a thickness exceeding 6 mm. Specifically, it covers coniferous wood of fir (Abies spp.) and spruce (Picea spp.) that has not undergone treatment. The "rough" designation indicates that the wood in this subcategory has not been further worked beyond the initial sawing, chipping, slicing, or peeling stages and may retain its natural saw marks or have irregular surfaces.

This classification is distinguished from its sibling category, 4407.12.00.20 "Other," by its specific exclusion of treated wood. While both fall under the broader umbrella of coniferous fir and spruce lumber exceeding 6 mm in thickness, category 4407.12.00.19 is reserved for wood that has not been subjected to any preservative treatments, fire retardants, or other chemical or physical modifications beyond the initial processing stages.

As this is a leaf node within the HTS structure, there are no further subcategories. Therefore, classification under 4407.12.00.19 is final for untreated coniferous wood of fir and spruce, processed to a thickness greater than 6 mm, and not further worked than sawing, chipping, slicing, or peeling. Importers should ensure the absence of any treatment applications to correctly assign goods to this specific classification.
