6102.90 - Of other textile materials:

This HTS category, 6102.90, encompasses knitted or crocheted outerwear for women or girls, such as overcoats, carcoats, capes, cloaks, anoraks, windbreakers, and similar garments, specifically when they are manufactured from textile materials *other than* wool, fine animal hair, cotton, or man-made fibers. This classification serves as a residual category for garments made from a broad range of less common or mixed textile inputs not otherwise specified.

In contrast to its sibling categories, 6102.90.00 does not specify the primary fiber content as wool or fine animal hair (6102.10), cotton (6102.20), or man-made fibers (6102.30). Therefore, any knitted or crocheted outerwear falling under the general description of heading 6102, but not primarily composed of those specified fibers, will find its classification here.

Within this category, two subcategories exist to further refine the classification based on specific material composition. 6102.90.10.00 covers garments that contain 70 percent or more by weight of silk or silk waste, a distinct classification due to the unique properties and value of silk. The remaining garments, which do not meet the silk criterion and are not covered by other specific fiber headings, fall under the residual subcategory 6102.90.90, "Other."
