6209.30.10.00 - Blouses and shirts, except those imported as parts of sets (239)

This HTS category, 6209.30.10.00, specifically classifies blouses and shirts designed for infants and children, provided they are not imported as part of a larger set of garments. The defining characteristic is the garment type (blouses and shirts) and the intended wearer (babies and children). The material composition is also crucial, as this code applies to items made of synthetic fibers, aligning with its parent category within "Of synthetic fibers."

Distinguishing this category from its siblings is straightforward. While 6209.30.20.00 covers trousers, breeches, and shorts for the same age group and fiber type, this node focuses exclusively on upper-body garments. The remaining sibling, 6209.30.30, serves as a catch-all for "Other" babies' clothing accessories made of synthetic fibers that do not fit into the more specific categories.

As this is a leaf node within the HTS structure, there are no further subcategories. Therefore, classification relies solely on meeting the criteria of being a blouse or shirt for infants and children, composed of synthetic fibers, and not being part of a garment set. Examples falling under this classification would include infants' t-shirts, baby blouses, and children's button-down shirts made from polyester, nylon, or acrylic fabrics, among other synthetic materials.
