3305.90.00.00 - Other

HTS 3305.90.00.00 encompasses all preparations for use on the hair that are not specifically classified under shampoos (3305.10), preparations for permanent waving or straightening (3305.20), or hair lacquers (3305.30). This residual category is crucial for ensuring comprehensive classification of all hair care products.

This classification is distinct from its siblings by excluding specific functionalities. For instance, it does not cover products designed primarily for cleansing the scalp and hair like shampoos. Similarly, it excludes products formulated for chemical manipulation of hair structure such as permanent wave lotions or straightening creams. It also differentiates itself from hair lacquers, which are specifically designed for holding hairstyles in place and are typically in aerosol or spray form.

Given that 3305.90.00.00 is a leaf node, its scope is defined by what it *is not*. This includes a wide array of hair care items such as hair conditioners, hair masks, hair oils, hair serums, hair pomades, hair waxes, styling creams, detanglers, and leave-in treatments. The key determining factor for classification under this heading is that the preparation is intended for application to the hair and does not fit the more specific descriptions of the preceding subheadings within 3305.
