6108.39 - Of other textile materials:

This HTS category, 6108.39, encompasses knitted or crocheted nightdresses and pajamas for women or girls that are not made of cotton or man-made fibers. Essentially, it captures sleepwear in these categories where the primary textile material falls outside the common classifications of cotton and synthetic fibers.

This classification serves as a residual category for nightdresses and pajamas. Its siblings, 6108.31 (of cotton) and 6108.32 (of man-made fibers), cover the most prevalent materials used in such garments. Therefore, 6108.39 is where items made from other specific fibers, such as wool, silk, or less common natural or regenerated fibers, will be classified.

Within 6108.39, further distinctions are made based on the specific textile material. Subcategories exist for nightdresses and pajamas predominantly composed of wool or fine animal hair, and for those containing a high percentage of silk or silk waste. The residual subcategory, "Other," will capture all remaining nightdresses and pajamas not meeting the criteria for the more specific material classifications.
