6203.43.70 - Containing 36 percent or more by weight of wool or fine animal hair

This HTS category encompasses trousers and breeches designed for men or boys, specifically those that are not knitted or crocheted. The defining characteristic for inclusion in this subcategory is the fiber content: these garments must contain 36 percent or more by weight of wool or fine animal hair. This material composition is critical for distinguishing these items from other trouser categories.

Within the broader classification of "Trousers, bib and brace overalls, breeches and shorts" under "Of synthetic fibers: Other: Other: Other:", this specific node focuses solely on the wool or fine animal hair blend. It distinguishes itself from potential sibling categories (though none are explicitly listed at this level) that might cover different material compositions, such as entirely synthetic or cotton-based trousers.

The primary subdivision within this category is for "Shorts." This indicates that while the parent category encompasses both trousers and breeches, this particular node further refines the classification to include only those specific types of garments made with a substantial wool or fine animal hair content. The existence of a separate "Shorts" subcategory allows for more precise tariff application based on garment length.
