6117.90.90.90 - Of man-made fibers (659)

This category, HTS 6117.90.90.90, specifically classifies parts of knitted or crocheted articles of apparel and clothing accessories that are made from man-made fibers. These parts are intended to be incorporated into or used with garments and accessories that fall under Chapter 61, which are exclusively knitted or crocheted. Examples include sleeves, collars, cuffs, or panels constructed from synthetic or regenerated cellulosic fibers that will be attached to knitted or crocheted garments or accessories.

This classification is distinguished from its siblings by the material composition of the part. While 6117.90.90.80 covers parts made of cotton and 6117.90.90.85 covers parts made of wool or fine animal hair, this subheading is for parts specifically manufactured from man-made fibers such as polyester, nylon, acrylic, or rayon. The critical determinant for classification here is the fiber content of the knitted or crocheted part itself.

As a leaf node, this category does not have further subcategories. Therefore, the focus for classification rests on ensuring that the part meets the criteria of being knitted or crocheted, belonging to apparel or clothing accessories covered by Chapter 61, and being exclusively made of man-made fibers, thus differentiating it from similar parts made from natural fibers.
