6212.10.90 - Other

This category, HTS Code 6212.10.90, encompasses brassieres that do not fall under specific material-based exclusions. These are undergarments designed to support and cover the breasts, and their classification here hinges on the absence of qualifying characteristics that would place them in other, more specific subheadings. The primary criterion for inclusion is that the brassieres are not made predominantly of silk or silk waste, which are classified elsewhere.

Distinguishing this category from its sibling, 6212.10.70, is crucial. The sibling category specifically addresses brassieres containing 70 percent or more by weight of silk or silk waste. Therefore, this current category, "Other," serves as a residual classification for brassieres composed of other textile materials, such as cotton, man-made fibers, or a blend of fibers where no single component, other than silk in the sibling category, meets a predominant percentage threshold for specific enumeration.

The subcategories within 6212.10.90 provide further refinement based on the primary textile fiber content. 6212.10.90.10 is designated for brassieres made predominantly of cotton, while 6212.10.90.20 covers those primarily composed of man-made fibers. Lastly, 6212.10.90.40 acts as a further residual for brassieres made from other materials or complex blends not specifically accounted for in the preceding subcategories, ensuring comprehensive coverage of all non-silk brassieres not otherwise specified.
