6107.21.00.20 - Boys' (351)

This HTS classification, 6107.21.00.20, specifically covers boys' nightshirts and pajamas that are knitted or crocheted and made of cotton. These garments are designed for sleepwear and loungewear purposes, fitting the broader category of men's or boys' sleepwear and similar articles within Chapter 61. The key defining elements for this code are the intended wearer (boys), the garment type (nightshirts and pajamas), the construction method (knitted or crocheted), and the primary material (cotton).

This category is distinguished from its sibling, 6107.21.00.10, by its specific designation for "Boys'." The sibling category encompasses the same types of garments (nightshirts and pajamas, knitted or crocheted, of cotton) but is intended for men. Therefore, the age and gender of the wearer are the crucial differentiating factors between these two closely related codes.

As this node is a leaf node within the HTS structure, there are no further subcategories to introduce. Classification at this level is definitive, with the combination of garment type, material, construction, and intended wearer fully defining the scope of the product. When classifying goods under this code, adherence to the precise definitions of "nightshirt" and "pajama" for boys, along with confirmation of cotton as the principal textile material, is essential.
