6109.90.10.90 - Other (639)

This classification, HTS Code 6109.90.10.90, encompasses "Other" garments that are knitted or crocheted, falling under the broader category of "Of man-made fibers" and "Women's or girls'". It specifically applies to articles of apparel that do not fit the more defined categories of t-shirts, tank tops, or singlets within the "Of other textile materials" group. This residual category serves as a catch-all for knitted or crocheted women's or girls' garments made from man-made fibers that are similar in nature or function but lack the specific characteristics to be classified under the preceding subheadings.

The distinction of this category lies in its exclusion of explicitly defined items. While sibling categories such as thermal undershirts (6109.90.10.75) have specific functional descriptions, this "Other" category captures garments that might share the basic construction of a simple knitted top but do not precisely align with the common definitions of t-shirts, tank tops, or singlets, nor possess the specialized thermal properties of thermal undershirts. It captures a variety of similar garments that are undeniably knitted or crocheted tops made from man-made fibers intended for women or girls.

As this is a leaf node, there are no further subcategories under HTS Code 6109.90.10.90. Therefore, classification within this heading relies on thoroughly assessing whether the garment is indeed a knitted or crocheted top of man-made fibers for women or girls, and importantly, that it does not meet the specific criteria for any preceding, more narrowly defined subheadings within the 6109.90.10.75 range.
