8542.39.00 - Other

HTS code 8542.39.00, described as "Other," serves as a residual category within the classification of electronic integrated circuits. This category encompasses integrated circuits that do not fit into the more specific subheadings such as processors and controllers (8542.31.00), memories (8542.32.00), or amplifiers (8542.33.00.01). The primary criterion for classification under 8542.39.00 is the absence of a more precise designation within the Harmonized Tariff Schedule based on the circuit's primary function or design.

This category is distinguished from its sibling headings by its broad inclusiveness. While 8542.31.00 focuses on circuits that perform processing or control functions, and 8542.32.00 specifically covers data storage circuits, and 8542.33.00.01 deals with signal amplification, 8542.39.00 captures all other electronic integrated circuits that do not fall under these specialized classifications. This ensures that all types of integrated circuits, even those with less common or combined functionalities, are accounted for within the tariff schedule.

The subcategories of 8542.39.00 further refine this broad heading. It includes specific types of circuits such as RF transceivers (8542.39.00.10) and active filters (8542.39.00.20). Additionally, it contains provisions for data converters, further broken down by their performance characteristics, with 8542.39.00.70 covering those with adjustable performance and 8542.39.00.90 serving as a final residual for any remaining data converters not elsewhere specified. These subdivisions allow for greater accuracy in classifying the diverse range of integrated circuits that do not fit into the primary sibling categories.
