4403.25.01.50 - Western hemlock (Tsuga heterophylla)

This classification covers Western hemlock (Tsuga heterophylla) in its rough, unworked state. Specifically, it includes logs and timber where the smallest cross-sectional dimension measures 15 centimeters or more. The wood may be stripped of bark or sapwood, or it may be roughly squared. This category falls under coniferous woods that meet the size criteria, preceding further specific subdivisions.

Distinguishing this from its siblings, 4403.25.01.40 is for Douglas-fir, and 4403.25.01.52 is for other types of hemlock. Similarly, 4403.25.01.55 and 4403.25.01.57 are for Western red cedar and other cedar species, respectively. The "Other" category at 4403.25.01.64 serves as a residual for coniferous logs and timber of this size that do not fit the more specific descriptions provided.

As this is a leaf node in the HTS database, there are no further subcategories. Classification decisions at this level are therefore final and depend on the accurate identification of the species as Western hemlock and confirmation that it meets the physical dimension requirements of the parent category.
