8302.10.60.90 - Other

This category, HTS Code 8302.10.60.90, encompasses "Other" base metal hinges and their parts when made of iron, steel, aluminum, or zinc, which do not fall under the more specific classifications for interior/exterior doors or furniture and cabinets. It serves as a residual category for hinges designed for a broad range of applications not explicitly defined elsewhere at this level.

To differentiate this category from its siblings, consider the primary intended use of the hinge. HTS 8302.10.60.30 specifically covers hinges for most types of interior and exterior doors, excluding those for garages, overhead, or sliding applications. Similarly, HTS 8302.10.60.60 is designated for hinges specifically intended for use in furniture and cabinets. Therefore, 8302.10.60.90 would capture hinges for less common applications, such as those found on specialized equipment, display cases not considered furniture, or historical reproductions where the primary function doesn't align with the defined door or furniture categories.

As this is a leaf node in the HTS, there are no further subdivisions under this specific code. Classification into this residual category relies on carefully examining the hinge's design, dimensions, and intended end-use to confirm it does not meet the criteria for any more specific sibling classification. For instance, a hinge designed for a small marine locker or a custom-built industrial enclosure might find its classification here if it doesn't fit the other predefined uses.
