5602.21.00.00 - Of wool or fine animal hair (414)

This HTS category, 5602.21.00.00, specifically classifies nonwovens (felt) that are *not* impregnated, coated, covered, or laminated, and are made *exclusively* from wool or fine animal hair. This includes materials like felt produced through needle-punching or other mechanical processes, where the fibers are interlocked to form a cohesive web. The defining characteristic is the absence of any additional treatments that alter the surface or structure of the felt, beyond the initial manufacturing process.

This category distinguishes itself from its sibling, 5602.29.00.00, which covers similar nonwovens but is made from "other textile materials." While both fall under the broader heading for felt not otherwise treated, the key differentiator here is the precise fiber content. If the felt is composed of wool or materials like cashmere, angora, or mohair, it will be classified under 5602.21.00.00. If it's made from cotton, synthetic fibers, or a blend not primarily composed of wool or fine animal hair, it would fall into the sibling category.

As a leaf node in the HTS classification, 5602.21.00.00 does not have further subdivisions. Therefore, the focus for classification within this code is on confirming the material composition (wool or fine animal hair) and the absence of impregnation, coating, covering, or lamination on the felted material. Examples of goods that might fall here include undyed or naturally colored wool felt sheets used for craft purposes, padding, or insulation, provided no further treatments have been applied.
