4406.12.00.00 - Nonconiferous

This HTS classification, 4406.12.00.00, specifically covers railway or tramway sleepers (cross-ties) that are made of wood and are not impregnated. These are essential components used to support and hold railway tracks in place. The "nonconiferous" designation is crucial, meaning the wood used for these sleepers is derived from deciduous trees, such as oak, beech, or maple, as opposed to coniferous trees like pine or fir.

Distinguishing this category from its sibling, 4406.11.00.00, is the type of wood employed. While both refer to non-impregnated wooden sleepers, 4406.11.00.00 is reserved for sleepers manufactured from coniferous wood. Therefore, the primary differentiator here is the botanical origin and characteristics of the timber used, which can influence durability, cost, and treatment requirements.

As a leaf node in the HTS structure, 4406.12.00.00 does not have further subdivisions. Classification within this code is definitive for non-impregnated, nonconiferous wooden sleepers. This means that any wooden sleeper fitting these exact criteria, regardless of size or specific deciduous wood species, will fall under this heading. The absence of impregnation is a key characteristic, implying the wood has not undergone any chemical treatment to enhance its resistance to decay or insects, differentiating it from other potential treatments not specified at this level.
