Overview
HTS category 8542 encompasses electronic integrated circuits, commonly known as microchips or chips. These are complex electronic components that contain a vast number of interconnected transistors, resistors, and capacitors fabricated onto a single semiconductor substrate. Integrated circuits are the foundational building blocks for virtually all modern electronic devices, performing a wide range of functions from simple logic operations to complex data processing.
This category is distinct from its sibling categories within Section XVI, which cover a broad spectrum of machinery and electrical equipment. Unlike general electrical machinery or discrete components, 8542 specifically targets highly miniaturized, manufactured semiconductor devices designed to perform specific electronic functions. It excludes separate parts, which are classified under its own subcategory.
Within HTS 8542, the primary distinction is between the integrated circuits themselves and their constituent parts. The main entries would detail the various types of integrated circuits based on their function (e.g., microprocessors, memory chips, application-specific integrated circuits) and architectural design. The subcategory 8542.90.00.00 is reserved for parts and accessories of these integrated circuits, such as substrates or packaging materials that are not yet fully functional integrated circuits.
