6217.90.90.55 - Of wool or fine animal hair (448)

This HTS subheading, 6217.90.90.55, specifically classifies parts of garments or clothing accessories, excluding knitted or crocheted items, that are designed for use with trousers and breeches and are made from wool or fine animal hair. These parts can include elements such as linings, interfacings, pockets, waistbands, or decorative trims, provided they are fabricated from these particular natural animal fibers. The primary classification criterion here is the material composition, necessitating that the part be predominantly composed of wool or fine animal hair to qualify for this entry.

Distinction from sibling categories is crucial for accurate classification. Unlike 6217.90.90.50, which covers similar parts made of cotton, or 6217.90.90.60, which applies to parts made of man-made fibers, this subheading is exclusively for wool and fine animal hair. Category 6217.90.90.70 serves as a residual category for parts of trousers and breeches made from other materials not specified elsewhere. Therefore, the presence and predominance of wool or fine animal hair are the definitive factors for selecting this specific subheading.

As this is a leaf node within the HTS structure, there are no further subcategories. Classification under 6217.90.90.55 is definitive once the article is identified as a part of trousers or breeches, not knitted or crocheted, and its constituent material is determined to be wool or fine animal hair. Examples include woolen pocket bags, woolen waistband interlinings, or ornamental woolen braid intended for attachment to trousers.
