8486 - Machines and apparatus of a kind used solely or principally for the manufacture of semiconductor boules or wafers, semiconductor devices, electronic integrated circuits or flat panel displays; machines and apparatus specified in note 11(C) to this chapter; parts and accessories:

This HTS category, 8486, encompasses specialized machinery and apparatus designed exclusively or primarily for advanced manufacturing processes within the electronics industry. It covers equipment crucial for the production of semiconductor boules and wafers, the fundamental building blocks of microchips, as well as machines used for fabricating semiconductor devices and intricate electronic integrated circuits. Furthermore, this classification extends to apparatus for the creation of flat panel displays, such as those found in televisions and smartphones, and includes machinery fulfilling the specific criteria outlined in Note 11(C) to Chapter 84.

Unlike other headings within Section XVI that cover more general machinery or mechanical appliances, heading 8486 is narrowly focused on the highly technical and automated processes involved in semiconductor and display manufacturing. Its scope is distinct from broader categories like 8479 (Machines and mechanical appliances having individual functions, not elsewhere specified or included) or headings related to general industrial machinery, by virtue of its exclusive dedication to the specialized needs of electronic component fabrication.

The subcategories within 8486 provide a detailed breakdown of these manufacturing functions. 8486.10 covers machines for boule and wafer production, 8486.20 addresses the manufacturing of semiconductor devices and integrated circuits, and 8486.30 pertains to flat panel display production. 8486.40 is reserved for machines meeting the specific requirements of Note 11(C), and 8486.90 serves as a catch-all for essential parts and accessories to all machines classified under this heading, ensuring comprehensive coverage for this critical segment of the manufacturing sector.
