5103.10.00.00 - Noils of wool or of fine animal hair 🖩

This HTS category, 5103.10.00.00, specifically covers "Noils of wool or of fine animal hair." Noils are the shorter fibers that are separated from the longer staple fibers during the combing process of wool or fine animal hair. These short fibers, by their nature, are distinct from the longer fibers intended for spinning into yarn or fabric. The classification is specifically for these residual, shorter noil fibers, not for the combed staple fibers themselves.

It is important to distinguish this category from its siblings. While 5103.20.00.00 covers "Other waste of wool or of fine animal hair," and 5103.30.00.00 addresses "Waste of coarse animal hair," this subheading is precisely for the noils derived from the combing of *wool* or *fine* animal hair (such as cashmere, mohair, alpaca, vicuña, camel, etc.). This means that noils from coarse animal hair would fall under 5103.30.00.00, and other waste materials not specifically identified as noils, but still originating from wool or fine animal hair, would be classified under 5103.20.00.00.

As a leaf node within the HTS, this category does not have further subcategories. Therefore, classification under 5103.10.00.00 hinges on the precise identification of the material as noils of wool or fine animal hair. Practical considerations for classification would involve examining the fiber length and the origin of the material, confirming it has been processed through a combing operation that separates these shorter noil fibers from the main staple.
