8518.10.80 - Other

This HTS classification covers microphones that do not meet the specific criteria of sibling category 8518.10.40.00. Specifically, it applies to microphones whose frequency range deviates from the 300 Hz to 3.4 kHz band, or whose physical dimensions (diameter exceeding 10 mm or height exceeding 3 mm) fall outside the specified limits for telecommunication use. This category therefore encompasses a broader range of microphones, including those designed for professional audio recording, public address systems, and other general audio applications, provided they are not specifically classifiable under other headings.

Category 8518.10.80 serves as a residual classification for microphones within the broader heading 8518. It distinguishes itself from 8518.10.40.00 by the absence of the stringent technical specifications defining the latter, which is exclusively for narrow-band, miniaturized microphones intended for telecommunications.

Within this category, further subdivisions exist to refine the classification. The subcategory 8518.10.80.30 is designated for microphones specifically. The subcategory 8518.10.80.40, conversely, captures any remaining microphone-related items or accessories not explicitly classified as microphones themselves but related to their function or support, thereby ensuring comprehensive coverage under this heading.
