9401.91.90.90 - Other

This HTS category, 9401.91.90.90, encompasses "Other" parts for seats (excluding those specifically for medical or dental purposes under heading 9402). These parts are predominantly made of wood and are not explicitly categorized elsewhere within the "Parts of wood" subdivision of seating components. This designation serves as a residual category for wooden seat parts that do not fit into more specific classifications.

It is crucial to distinguish this category from its sibling, 9401.91.90.10, which specifically covers wooden parts for children's highchairs, booster seats, and similar child seating. Therefore, 9401.91.90.90 is intended for adult seating components or wooden parts of children's seats that do not align with the specific definition provided for the sibling category.

As this is a leaf node, there are no further subcategories. Classification within this code relies on ensuring the part is made of wood, is a component of a seat falling under heading 9401, and does not qualify for any more specific sub-classification of wooden seat parts, including those for children's seating. Practical classification considerations will focus on the material composition and the intended application of the wooden component within the broader context of furniture seating.
