6104.69.40.10 - Bib and brace overalls (759)

This HTS category specifically classifies bib and brace overalls that are knitted or crocheted and are composed of 70 percent or more by weight of silk or silk waste. These garments are characterized by their full-length trousers attached to a bib front and adjustable shoulder straps (braces), designed for wear as outer garments. The primary material composition, being predominantly silk or silk waste, is the key determining factor for inclusion in this particular sub-heading.

Distinguishing this classification from its sibling, HTS 6104.69.40.20, is crucial. While both fall under "trousers, bib and brace overalls, breeches and shorts" made of "other textile materials" and "containing 70 percent or more by weight of silk or silk waste," this specific sub-heading is exclusively for "bib and brace overalls." The sibling category encompasses trousers, breeches, and shorts, excluding bib and brace overalls from its scope.

As this node is a leaf node in the HTS, there are no further subdivisions. Therefore, classification within this HTS code requires a definitive assessment that the garment is indeed a bib and brace overall and meets the stringent material requirement of at least 70% silk or silk waste by weight. This ensures accurate duty assessment and trade statistics for these specialized silk garments.
