6003.10 - Of wool or fine animal hair:

This HTS category, 6003.10, specifically encompasses knitted or crocheted fabrics with a width not exceeding 30 centimeters, that are exclusively made from wool or fine animal hair. This classification applies to a broad range of such fabrics, excluding those already categorized under headings 6001 or 6002, which may cover specific types of pile or loop fabrics. The defining characteristic here is the material composition, demanding that the fabric's primary fibers be derived from wool or fine animal hair.

When classifying fabrics under heading 6003, it is crucial to differentiate based on the material. While 6003.10 focuses on wool and fine animal hair, its sibling categories cover other primary fiber types. For instance, 6003.20 pertains to fabrics of cotton, 6003.30 to synthetic fibers, and 6003.40 to artificial fibers. The "Other" category, 6003.90, is reserved for fabrics of this width that do not fit into the aforementioned material-specific headings.

Within 6003.10, further distinctions are made to refine classification. The subcategories, 6003.10.10.00 and 6003.10.90.00, differentiate between "Open-work fabrics, warp knit" and "Other" fabrics. This allows for specific identification of particular knitting techniques and construction styles within the broader category of wool or fine animal hair fabrics not exceeding 30 cm in width, ensuring precise tariff application.
