6603 - Parts, trimmings and accessories of articles of heading 6601 or 6602:

Heading 6603 encompasses a diverse range of components, trimmings, and accessories specifically designed for use with articles classified under headings 6601 (umbrellas and sun umbrellas) and 6602 (walking sticks, seatsticks, whips, and riding-crops). This category includes items such as umbrella ribs, stretchers, runners, handles, and tops, as well as parts for walking sticks like ferrules, grips, and ornamental elements. It is important to note that these are exclusively parts and accessories; the complete umbrellas, sun umbrellas, walking sticks, etc., fall under the respective preceding headings.

This heading is distinct from sibling categories within the broader HTS structure which cover a wide array of goods, from live animals in Chapter 01 to various manufactured articles. Specifically within Chapter 66, heading 6603 is differentiated from headings 6601 and 6602 by its focus solely on the constituent parts rather than the finished products they are intended to be assembled into or affixed to. Therefore, while heading 6601 covers complete umbrellas, heading 6603 would cover, for instance, the frame of an umbrella if imported separately.

The subcategories under 6603 further refine this classification. Subheading 6603.20 specifically addresses umbrella frames, including those that are already mounted onto shafts or sticks, representing a significant and often complex component of an umbrella. The residual category, 6603.90, covers all other parts, trimmings, and accessories not specifically provided for in 6603.20, ensuring comprehensive coverage for the wide variety of items that constitute the building blocks of articles in headings 6601 and 6602.
