4401.39.42.10 - Sawdust

This HTS classification, 4401.39.42.10, specifically covers sawdust. Sawdust refers to the fine particles resulting from the sawing or cutting of wood. In this context, it is considered "other" within the subcategory of agglomerated wood waste and scrap. This means it includes sawdust that has been processed or formed into denser units like logs, briquettes, or pellets for easier handling and use, particularly as fuel.

It is important to distinguish this classification from its sibling, 4401.39.42.20, which covers shavings. While both are forms of wood waste, shavings are typically larger, often curled or curled pieces produced by planing or shaping wood, whereas sawdust comprises much finer particles. The "Other" designation at this level signifies that this category is for sawdust that does not fit into more specific sub-classifications of agglomerated wood waste.

As this is a leaf node, there are no further subcategories. Therefore, classification under 4401.39.42.10 is definitive for sawdust, provided it is agglomerated in the described forms. The primary criteria for inclusion are the material (wood), its form (fine particles), and its agglomeration into denser units for practical application.
