8542.31.00.20 - 16-bit

This HTS category, 8542.31.00.20, specifically classifies 16-bit electronic integrated circuits that function as processors or controllers. These integrated circuits are designed to execute instructions and manage the operations of various electronic devices. They contain the necessary logic and circuitry to perform arithmetic and logical operations, making them central components in microprocessors, microcontrollers, and other digital processing units.

The distinction of this category lies in its bit-width designation. It differentiates 16-bit controllers from their 8-bit counterparts (8542.31.00.15), which have a narrower data processing capability, and from 32-bit controllers (8542.31.00.25), which handle larger data chunks and offer more advanced functionalities. The "Other" category (8542.31.00.30) serves as a catch-all for any processors or controllers that do not fit into the specific bit-width classifications provided.

As a leaf node, this category does not have further subdivisions. Therefore, classification within this code relies heavily on confirming the integrated circuit's architecture is designed for 16-bit operations and that its primary function is that of a processor or controller, as defined by the parent heading. Importers and exporters should ensure the technical specifications of the integrated circuit clearly indicate its 16-bit architecture and its role in data processing or system control to accurately apply this classification.
