4014.90.10.00 - Nursing nipples

This HTS category, 4014.90.10.00, specifically covers nursing nipples manufactured from vulcanized rubber, excluding hard rubber. These items are designed for infant feeding and are characterized by their teat-like shape intended to be attached to bottles. The classification hinges on the material being vulcanized rubber and the primary function as a nursing nipple.

While this category is for nursing nipples, its sibling category, 4014.90.50.00, encompasses "Other" hygienic or pharmaceutical articles made from vulcanized rubber. This distinction is crucial; 4014.90.10.00 is exclusively for nursing nipples, whereas the "Other" category would apply to a broader range of rubber articles used for hygienic or pharmaceutical purposes that do not fit the specific definition of a nursing nipple.

As this is a leaf node within the HTS, there are no further subcategories. Therefore, classification under this code depends on meeting the explicit criteria of being a nursing nipple made of vulcanized rubber. Examples would include standard silicone or latex nipples for baby bottles, regardless of whether they come with any fittings of hard rubber.
