About Duty Rates: Rates are divided into Column 1 and Column 2. Column 1 is subdivided into General (normal trade relations rates for all countries not eligible for special programs) and Special (preferential rates for countries with free trade agreements or preference programs). Column 2 rates apply to products from Cuba, North Korea, Belarus, and Russia. When no special rate exists for a classification, General rates apply.

Overview

This HTS classification, 8542.31.00.25, specifically covers electronic integrated circuits that function as processors and controllers, characterized by their 32-bit architecture. These are sophisticated chips designed to execute instructions, manage data flow, and perform complex computational tasks. Examples include microcontrollers and CPUs with a 32-bit data bus, often found in a wide range of electronic devices from personal computers and smartphones to industrial automation systems and automotive electronics.

The distinction between this category and its siblings lies in the architectural word size. Category 8542.31.00.15 pertains to 8-bit controllers, while 8542.31.00.20 covers 16-bit controllers. This 32-bit classification, therefore, encompasses integrated circuits that process data in 32-bit chunks, offering enhanced performance and capability compared to their 8-bit and 16-bit counterparts. The "Other" category, 8542.31.00.30, serves as a catch-all for controllers that do not fit the specific bit-size classifications.

As this is a leaf node in the HTS structure, there are no further subcategories. Classification within 8542.31.00.25 is determined by the definitive 32-bit architecture of the processor or controller integrated circuit. Further subdivision would typically depend on specific functions or combinations with other circuit types if those were delineated at a more granular level within the HTS.
