9401.99.35.80 - Other

This HTS category, 9401.99.35.80, encompasses "Other" parts for seats, specifically those manufactured from rubber or plastics, that do not fall into more specific subcategories. This classification applies to a broad range of components, such as casters, armrests, leg supports, back panel elements, and trim pieces, made primarily of rubber or plastic materials, intended for use in the construction or repair of non-medical seating articles covered by heading 9401.

It is crucial to distinguish this residual category from its sibling, 9401.99.35.10, which is reserved exclusively for parts of children's highchairs, booster seats (excluding those for motor vehicles), and similar specialized seating designed for infants and toddlers. If a rubber or plastic part's primary function is related to these child-specific seats, it should be classified under the sibling category. This category, 9401.99.35.80, is therefore for all other plastic or rubber parts of general seating not otherwise specified.

As this is a leaf node in the HTS, there are no further subcategories for this specific code. Classification at this level hinges on the material composition (rubber or plastics) and the absence of a more precise classification based on the type of seat or specific component function. Therefore, careful examination of the part's physical characteristics, intended use with a seat covered by 9401, and material composition is paramount to ensure correct classification within this residual category.
