This HTS category, 3926.90.21.00, specifically covers a range of personal hygiene and medical care articles manufactured from plastics, excluding those incorporating glass or metal. The primary items include ice bags, douche bags, enema bags, and hot water bottles, along with their associated fittings. It also encompasses invalid and similar nursing cushions, dress shields, pessaries, prophylactics, and bulbs for syringes. Furthermore, this classification includes syringes, excluding hypodermic syringes, and their fittings, provided they are not made in part of glass or metal.

Distinguishing this category from its siblings, we observe that while other entries under 3926.90.XX.XX might also be "other articles of plastics," they are dedicated to distinct product types. For instance, 3926.90.10.00 is for buckets and pails, and 3926.90.16.00 is for pacifiers. This specific subcategory is characterized by its focus on personal medical and hygiene devices. It is crucial to note the exclusion of articles primarily composed of or incorporating glass or metal, which would fall under different HTS headings.

As this classification represents a leaf node within the HTS, there are no further subdivisions. Therefore, the classification hinges on accurately identifying the described articles as being made from plastics and fulfilling the specific functional and material criteria outlined in the description. Classification relies on the intended use and physical composition of the product, ensuring it aligns precisely with the enumerated items.
