6203.12.10.00 - Containing 36 percent or more by weight of wool or fine animal hair (443)

This HTS category, 6203.12.10.00, specifically covers men's or boys' suits that are predominantly composed of wool or fine animal hair. For a suit to fall under this classification, the weight of wool or fine animal hair must constitute 36 percent or more of the total weight of the garment. This aligns with the broader classification of men's or boys' suits falling under Chapter 62, which pertains to apparel and clothing accessories not knitted or crocheted.

The distinguishing factor for this category, 6203.12.10.00, is its specific material composition requirement regarding wool or fine animal hair content. It differentiates itself from its sibling category, 6203.12.20, which covers "Other" suits of synthetic fibers. While both are subcategories of "Suits" within the "Of synthetic fibers" group, this specific code zeroes in on those suits with a significant wool or fine animal hair component, implying a blend where synthetic fibers are present but do not dominate in weight to the extent that the garment would be classified solely as synthetic.

As this is a leaf node within the HTS classification, there are no further subcategories to introduce. Therefore, the classification is finalized at this level based on the specified criteria. The focus remains on ensuring the garment is a suit, intended for men or boys, and meets the 36% or more wool or fine animal hair by weight threshold, distinct from other suit classifications that may be composed primarily of different fiber types or blends.
