6506.91.00.60 - Other

This category encompasses "Other" headgear made of rubber or plastics, which do not fit into more specific classifications within heading 6506. This includes a wide range of head coverings designed for protection, fashion, or specialized purposes, provided they are primarily constructed from rubber or plastic materials. Examples might include certain types of protective helmets not otherwise specified, flexible plastic caps for industrial use, or novelty headwear fashioned from these polymers.

It is crucial to distinguish this classification from its siblings. "Bathing caps" (6506.91.00.30) are specifically designed for use in water to keep hair dry. "Visors, or other headgear which provides no covering for the crown of the head" (6506.91.00.45) are characterized by their lack of full crown coverage, whereas this residual category captures those rubber or plastic headgear that *do* cover the crown of the head and are not otherwise detailed.

As a leaf node, this classification does not have further subcategories. Therefore, classification into this code relies on fulfilling the general requirements of heading 6506 for "other headgear," the specific material requirement of being of rubber or plastics, and not falling under any more granular subheadings or specifically enumerated items at the same or higher levels of the HTS. The defining characteristic is the material composition and the absence of a more precise classification.
