4412.39.50.30 - With at least one outer ply of long leaf pine (Pinus palustris), short leaf pine (Pinus echinata), southern yellow pine (loblolly pine) (Pinus taeda), slash pine (Pinus elliotti), pitch pine (Pinus rigida) or Virginia pine (Pinus virginiana)

This HTS classification, 4412.39.50.30, covers specific types of plywood that are constructed with at least one outer ply made from a particular group of coniferous wood species. These include long leaf pine (*Pinus palustris*), short leaf pine (*Pinus echinata*), southern yellow pine (loblolly pine, *Pinus taeda*), slash pine (*Pinus elliotti*), pitch pine (*Pinus rigida*), and Virginia pine (*Pinus virginiana*). The broader category encompasses other plywood where each ply does not exceed 6 mm in thickness and both outer plies are of coniferous wood.

This specific classification is distinguished from its sibling categories by the precise species of pine or other listed coniferous wood used for the outer ply. For instance, 4412.39.50.10 covers plywood with at least one outer ply of Douglas fir (*Pseudotsuga menziesii*), while 4412.39.50.50 is a residual category for other plywood meeting the general coniferous outer ply criteria but not falling into the more specific pine or Douglas fir classifications.

As this is a leaf node in the HTS structure, there are no further subcategories under 4412.39.50.30. Therefore, classification hinges entirely on the presence of the specified pine or southern yellow pine species in at least one of the outer plies of the plywood. The focus remains on the material composition of the outer layers to differentiate it within the broader "other plywood with both outer plies of coniferous wood" grouping.
