6603.90 - Other:

This category, HTS 6603.90, encompasses parts, trimmings, and accessories specifically for umbrellas and sun umbrellas (heading 6601) and walking sticks, seatsticks, whips, and riding-crops (heading 6602) that are not specifically covered by other subheadings within heading 6603. It serves as a residual category for components that are integral to these articles but do not fit into more precise classifications.

Unlike the sibling category 6603.20, which specifically covers umbrella frames, including those mounted on shafts, this category is for other distinct parts and trimmings. For instance, while 6603.20 addresses the skeletal structure of an umbrella, 6603.90 would cover elements attached to or used in conjunction with these frames and shafts, but not the frames themselves.

The subcategories within 6603.90 provide further refinement. 6603.90.41.00 specifically addresses umbrella handles, knobs, tips, and caps, which are often decorative or functional additions to the shaft. The residual subheading, 6603.90.81.00, is for any remaining parts, trimmings, and accessories that do not fall into the more narrowly defined subcategories, ensuring comprehensive classification for all components of articles falling under headings 6601 and 6602.
