9603.90 - Other:

HTS code 9603.90, designated as "Other," encompasses a diverse range of cleaning and dusting implements not specifically categorized under other subheadings within heading 9603. This category serves as a residual classification for items that fit the general description of brooms, brushes, mops, or feather dusters, but do not meet the specific criteria for twigs or vegetable materials (9603.10), toilet brushes (9603.21-9603.29), artists' or cosmetic brushes (9603.30), paint brushes or rollers (9603.40), or machine/appliance parts (9603.50).

To differentiate 9603.90 from its siblings, consider the material composition and intended primary use. For instance, while 9603.10 exclusively covers brooms and brushes made from natural vegetable materials, 9603.90 may include items made from synthetic fibers or other materials. Similarly, it excludes brushes specifically designed for personal grooming or cosmetic application as classified under 9603.21 through 9603.30. The exclusion of paint-related items (9603.40) and machine parts (9603.50) further refines the scope of 9603.90.

Within HTS 9603.90, two primary subdivisions exist: 9603.90.40.00 for feather dusters, which are specifically identified by their construction and function, and 9603.90.80 for all "Other" items. The "Other" category (9603.90.80) is thus the ultimate residual classification for any remaining miscellaneous brushes, mops, or dusting tools that do not fall into any of the more specific subheadings. This ensures comprehensive coverage for all items within the broader scope of heading 9603.
