4407.13.00.00 - Of S-P-F (spruce (Picea spp.), pine (Pinus spp.) and fir (Abies spp.))

This HTS classification covers coniferous wood that has been sawn or chipped lengthwise, sliced or peeled, and has a thickness exceeding 6 mm. Crucially, the wood in this category is specifically identified as S-P-F, which denotes a mixture of Spruce (Picea spp.), Pine (Pinus spp.), and Fir (Abies spp.). These woods may have undergone further processing such as planing, sanding, or end-jointing, but their primary characteristic remains their coniferous origin and the specific blend of these three species.

Distinguishing this category from its siblings is vital for accurate classification. Unlike 4407.11.00 which exclusively covers pine, or 4407.12.00 which covers fir and spruce but not necessarily as a defined S-P-F blend, 4407.13.00.00 specifically encompasses wood identified as S-P-F. It also differs from 4407.14.00.00, which is designated for Hem-fir, a distinct combination of Western hemlock and fir. The "Other" category, 4407.19.00, serves as a residual for coniferous woods that do not fit the specific definitions of pine, fir, spruce, or Hem-fir.

As this classification (4407.13.00.00) represents a leaf node, there are no further subcategories to introduce. Classification at this level is dependent on the precise identification of the wood as a blend of Spruce, Pine, and Fir species, conforming to the "S-P-F" designation, and meeting the general criteria of sawn, chipped, sliced, or peeled coniferous wood over 6 mm in thickness.
