4403.21.01.25 - Ponderosa pine (Pinus ponderosa)

This HTS category, 4403.21.01.25, specifically classifies ponderosa pine (Pinus ponderosa) in its rough, unprocessed form. This includes wood that has not been shaped beyond initial removal of bark or sapwood, or basic squaring. The defining characteristic of this classification is the species of pine, with the smallest cross-sectional dimension of the timber being 15 cm or greater. This ensures that only substantial pieces of ponderosa pine lumber are included here.

This classification is distinct from its sibling, 4403.21.01.20, which covers a specific group of Southern yellow pines and other related pine species. While both fall under "Other, coniferous" and "Of pine (Pinus spp.)" with the same dimensional criteria, 4403.21.01.25 is exclusively for ponderosa pine, ensuring precise identification and tariff application for this particular valuable timber.

As this is a leaf node within the HTS structure, there are no further subdivisions under 4403.21.01.25. The classification is complete at this level, encompassing all rough-sawn or roughly squared timber of ponderosa pine meeting the specified dimensional requirements. The focus remains on the raw material form of this particular coniferous species for customs purposes.
