5003.00.10.00 - Not carded or combed

This HTS category, 5003.00.10.00, specifically covers silk waste that has not undergone carding or combing processes. This includes raw silk waste such as cocoons that are unsuitable for the silk reeling process, as well as waste generated from yarn production and previously processed silk fibers that have been reduced to a garnetted state. The defining characteristic for inclusion in this subcategory is the absence of these mechanical preparation steps, which are typically employed to align fibers for subsequent spinning.

In contrast to its sibling category, 5003.00.90.00 (Other), this classification is strictly limited to silk waste that has not been carded or combed. The "Other" category would encompass all remaining silk waste falling under the broader heading 5003, which includes silk waste that has undergone carding or combing, or other forms of preparation not specifically identified here. Therefore, the crucial differentiating factor is the physical state of the silk fibers and the processing they have or have not received.

As this is a leaf node within the HTS classification system, there are no further subcategories to introduce. Classification within 5003.00.10.00 relies on a direct assessment of the physical characteristics of the silk waste to confirm the absence of carding or combing. Examples might include loose fibers, tangled material, or garnetted stock where the fibers remain largely disoriented and unprepared for spinning.
