6107.99.10.90 - Boys' (650)

This HTS category encompasses boys' undergarments, sleepwear, and loungewear that are knitted or crocheted and made from textile materials other than those specifically enumerated in preceding subcategories. The "(650)" designation likely refers to an internal statistical suffix for tracking purposes. Examples within this classification include boys' undershirts, briefs, pajamas, and dressing gowns crafted from synthetic or regenerated fibers, such as polyester, nylon, rayon, or acrylic.

It is crucial to distinguish this classification from its sibling, 6107.99.10.40, which specifically covers similar articles for men. The primary differentiating factor is the intended user: this subcategory is exclusively for garments designed for boys. If a garment is not clearly for boys or men, or if it is made from natural fibers like cotton or wool, it would be classified elsewhere.

As this is a terminal node within the HTS, there are no further subcategories. Classification within 6107.99.10.90 is determined by the garment's knitted or crocheted construction, its intended purpose (undergarment, sleepwear, loungewear), its sizing/demographic (boys'), and its material composition (man-made fibers, not otherwise specified). Accurate determination relies on verifying these key attributes against the merchandise being imported or exported.
