6111.30.30.00 - T-shirts, singlets and similar garments, except those imported as parts of sets (239)

This HTS category, 6111.30.30.00, specifically classifies knitted or crocheted t-shirts, singlets, and similar garments designed for babies, when these are made of synthetic fibers. The defining characteristic is the garment's construction and intended use for infants, coupled with the material composition. This classification is distinct from other categories within "Babies' garments and clothing accessories, knitted or crocheted: Of synthetic fibers," which cover trousers, breeches, shorts (6111.30.10.00), blouses and shirts (6111.30.20.00), and sweaters or similar upper body garments (6111.30.40.00). Therefore, items classified here are primarily focused on the basic t-shirt or singlet style for babies.

It is important to note that this classification excludes t-shirts and singlets when they are imported as part of a set, as such sets would be classified under a different provision. The focus remains on individual garments of this specific type and construction for babies, made from synthetic fibers. As this is a leaf node, there are no further subdivisions within this particular HTS code. Classification hinges on identifying the garment as a t-shirt or singlet, its intended use for infants, its knitted or crocheted construction, and its material being synthetic fiber.
