6207.21.00.30 - Men's (351)

This HTS classification covers men's nightshirts and pajamas made from cotton. These garments are specifically designed for sleeping or lounging at home and are distinct from other types of men's underwear or sleepwear. The defining characteristics for inclusion in this category are the intended use as nightwear and the primary textile material being cotton.

This category is differentiated from its sibling, 6207.21.00.40, which specifically covers boys' nightshirts and pajamas. While both categories fall under men's or boys' nightshirts and pajamas of cotton, the distinction here is strictly based on the gender of the wearer.

As this is a leaf node within the HTS structure, there are no further subcategories. Therefore, classification within 6207.21.00.30 is final once the criteria of being men's cotton nightshirts or pajamas are met. The focus for classification professionals would be on verifying the garment's intended use and the cotton content.
