6003.20 - Of cotton:

This HTS category, 6003.20, specifically addresses knitted or crocheted fabrics of cotton that do not exceed 30 cm in width. These fabrics are distinct from those made of wool, fine animal hair (6003.10), synthetic fibers (6003.30), or artificial fibers (6003.40). The defining characteristic for classification under 6003.20 is the material composition, which must be cotton.

Within this cotton-based category, further distinctions are made based on construction and specific application. The subcategories provide a more granular classification. For instance, fabrics that are open-work and utilize a warp knitting technique fall under 6003.20.10.00. All other knitted or crocheted cotton fabrics not exceeding 30 cm in width, which do not fit the open-work warp knit description, are classified under the "Other" subcategory, 6003.20.30.00. This structure allows for precise identification of different types of narrow cotton knitted or crocheted fabrics.
