8522.90 - Other:

This subheading, 8522.90, encompasses a broad range of "other" parts and accessories designed for use with apparatus classified under headings 8519 (record-players, record changers, automatic disk-playing machines) and 8521 (sound recorders and sound reproducing apparatus). Unlike the specific "pickup cartridges" found under the sibling category 8522.10.00.00, this subheading is a residual category for components and accessories that do not fit into more narrowly defined subheadings within 8522.

The items classified here are typically functional components that, when combined with the main apparatus, enable its operation or enhance its performance. This can include a wide variety of items such as printed circuit boards, motors, gears, drive mechanisms, housing components, antennas, and other specialized parts. The key criterion for classification under 8522.90 is that these parts and accessories must be suitable for use "solely or principally" with the sound recording and reproducing equipment described in headings 8519 and 8521.

Subdivisions within this category are established to further refine the classification based on the specific type of apparatus the part or accessory is intended for, or its inherent nature. For instance, there are specific provisions for assemblies and subassemblies, allowing for the classification of more complex multi-component parts. Additionally, there are distinctions made for parts of telephone answering machines, recognizing their unique functional requirements. Finally, the "Other" designation serves as a catch-all for all remaining parts and accessories that meet the general criteria of heading 8522 but are not specifically enumerated elsewhere within this subheading.
