9401.39.00 - Other

This category, HTS Code 9401.39.00, encompasses swivel seats with variable height adjustment that are not made primarily of wood. This includes a broad range of seating designed for ergonomic purposes, commonly found in office environments, workshops, or laboratories. The defining characteristic is the mechanical capability for both rotation and adjustment of seat height, catering to diverse user needs and tasks.

Distinguishing this category from its sibling, 9401.31.00 (Swivel seats with variable height adjustment: Of wood), is the material composition. While 9401.31.00 specifically covers such seats constructed predominantly from wood, 9401.39.00 applies to all other swivel seats with variable height adjustment, regardless of their primary material, which would typically include metal, plastic, or upholstered constructions.

The subcategories within 9401.39.00 further refine the classification based on the intended use of these seats. 9401.39.00.10 applies to "Household" swivel seats, referring to those designed for domestic use. Conversely, 9401.39.00.30, "Other," captures all remaining swivel seats with variable height adjustment that do not fall under the household designation, encompassing commercial, industrial, and institutional applications.
