6208.21.00 - Of cotton

This HTS category, 6208.21.00, specifically covers nightdresses and pajamas for women and girls that are primarily constructed of cotton. These garments are intended for sleepwear or loungewear and fall under the broader heading for women's or girls' undergarments and similar articles. The inclusion of "of cotton" is the defining material characteristic for this particular classification.

It is crucial to distinguish this category from its sibling, 6208.22.00.00, which covers nightdresses and pajamas made from man-made fibers. While both deal with similar garment types, the fundamental difference lies in the textile material. This category also differs from 6208.29, which encompasses nightdresses and pajamas made from "other textile materials," such as silk, wool, or linen, not classified elsewhere.

The subcategories within 6208.21.00.00 further refine the classification based on the fabric's construction and coloration. For example, 6208.21.00.10 specifically addresses articles with two or more colors in the warp and/or filling, suggesting a patterned or multi-hued fabric. The "Other" subcategory would encompass all remaining cotton nightdresses and pajamas not meeting the criteria for the more specific subdivisions, requiring careful examination of individual item characteristics.
