6203.11.60.00 - Of worsted wool fabric, made of wool yarn having an average fiber diameter of 18.5 microns or less (443) 🖩

This HTS classification, 6203.11.60.00, specifically covers men's or boys' suits constructed from worsted wool fabric. The defining characteristic of this category is the use of wool yarn with an average fiber diameter of 18.5 microns or less. This narrow specification focuses on suits made from finer grades of wool, often associated with higher quality and more refined garments.

The primary distinction between this category and its sibling, 6203.11.90.00 (Other), lies in the precise material composition. While both fall under men's or boys' wool suits, 6203.11.60.00 mandates the use of worsted wool fabric meeting the strict average fiber diameter criterion of 18.5 microns or less. The "Other" category would encompass wool suits that do not meet this specific micron requirement, potentially including those made from coarser wools or different wool blends not otherwise specified.

As this is a leaf node within the HTS, there are no further subcategories. Therefore, classification within this code is definitive and relies entirely on meeting the stipulated criteria of worsted wool fabric with an average fiber diameter of 18.5 microns or less for men's or boys' suits. Importers and exporters must ensure their merchandise strictly adheres to this material specification to correctly classify under this heading.
