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

HTS code 8542.31.00.30, designated as "Other" under controllers (including microcontrollers), serves as a residual category for electronic integrated circuits that function as processors and controllers but do not fit into more specific bit-width classifications. This category is intended for integrated circuits whose primary function is control or processing but whose architecture or design does not align with the defined 8-bit, 16-bit, or 32-bit distinctions found in sibling categories. Examples could include microcontrollers with mixed bit architectures, or those where the bit designation is not a primary distinguishing feature for classification purposes.

This classification is distinguished from its siblings, 8542.31.00.15 (8-bit), 8542.31.00.20 (16-bit), and 8542.31.00.25 (32-bit), by the absence of a clearly defined bit-width. While these sibling categories are precisely defined by their internal data processing width, this "Other" category captures controllers and processors that may have a different architectural focus or a bit architecture not explicitly listed. Importers and exporters should consult technical specifications to determine if an integrated circuit fits within the specific bit-width categories before resorting to this residual classification.

As this HTS code is a leaf node, there are no further subcategories. Therefore, classification into 8542.31.00.30 depends on a thorough examination of the integrated circuit's functionality as a processor or controller, and its inability to be precisely classified under the more specific bit-defined categories within the same heading. This ensures that all electronic integrated circuits performing processor and controller functions are accounted for within the Harmonized Tariff Schedule.
