6203.19.20.00 - Containing 36 percent or more by weight of wool or fine animal hair (443)

This HTS classification, 6203.19.20.00, covers men's or boys' suits primarily constructed from artificial fibers, with the defining characteristic that they contain 36 percent or more by weight of wool or fine animal hair. This means that while artificial fibers form a significant component, the presence of a substantial amount of wool or fine animal hair dictates its placement within this specific category. These suits are designed for formal or semi-formal wear and typically include matching jackets and trousers.

This category is distinct from its sibling, 6203.19.30.00, which is designated for "Other" suits of artificial fibers. The key differentiator lies in the specific percentage of wool or fine animal hair content. While both fall under suits of artificial fibers, this classification precisely identifies those with a high proportion of wool or fine animal hair, indicating a blend that influences material properties and potentially trade policies.

As a leaf node, this category does not have further subdivisions. Therefore, the focus for classification within 6203.19.20.00 is solely on the precise material composition, specifically the percentage of wool or fine animal hair present in suits predominantly made of artificial fibers. Importers and exporters must meticulously verify this material content through laboratory analysis or supplier documentation to ensure correct classification.
