3923.40.00 - Spools, cops, bobbins and similar supports

This HTS classification, 3923.40.00, specifically addresses spools, cops, bobbins, and similar supports, which are primarily used for winding, storing, or dispensing materials like thread, yarn, wire, film, or tape. These articles, while often plastic, are distinguished by their structural form designed to facilitate the unwinding or rewinding of these materials, and their primary function is as a carrier or support rather than a container for bulk goods.

It is crucial to differentiate this category from its siblings. For instance, 3923.10 covers more general rigid containers such as boxes and crates, while 3923.30.00 pertains to bottles and flasks. Similarly, 3923.50.00.00 is reserved for stoppers, lids, and caps that function as closures, not as structural supports for wound materials. This category is dedicated solely to the functional supports themselves.

Within 3923.40.00, two subcategories exist to further refine classification. 3923.40.00.10 specifically addresses photographic film reels and reel cans, recognizing the specialized nature of these items within the broader category of supports. The remaining items, not fitting the specific definition of photographic film reels and cans, are classified under 3923.40.00.50 as "Other" spools, cops, bobbins, and similar supports.
