6203.11 - Of wool or fine animal hair:

This HTS category, 6203.11, specifically classifies men's or boys' suits that are constructed primarily from wool or fine animal hair. These garments are distinguished by their material composition, which forms the core criterion for their inclusion here. The term "fine animal hair" typically refers to fibers such as cashmere, mohair, alpaca, vicuña, and camel hair, among others, which are valued for their softness and quality.

When classifying suits, it is crucial to differentiate them from sibling categories based on their constituent materials. HTS 6203.12 covers suits made of synthetic fibers, while 6203.19 encompasses suits composed of other textile materials not falling into the wool/fine animal hair or synthetic categories. Therefore, the presence of wool or fine animal hair is the decisive factor for classifying a suit under 6203.11.

Within this classification, further subdivisions exist to refine the classification of wool or fine animal hair suits. These subcategories address specific material inclusions that may influence the ultimate tariff treatment. One common subdivision considers the presence of silk or silk waste, specifically noting those suits containing 30 percent or more by weight of such materials. A separate "Other" category captures suits that do not meet this silk threshold, ensuring comprehensive coverage for all wool or fine animal hair suits.
