8486.90.00.00 - Parts and accessories

HTS Code 8486.90.00.00 encompasses parts and accessories specifically designed for use with the machinery classified under headings 8486.10 through 8486.40. This includes components, sub-assemblies, and auxiliary equipment that are integral to the operation, maintenance, or enhancement of machines used in the manufacturing of semiconductor boules or wafers, semiconductor devices, electronic integrated circuits, flat panel displays, or other specialized apparatus covered by Note 11(C) to Chapter 84.

While sibling categories 8486.10 through 8486.40 classify the complete machines for specific manufacturing processes, 8486.90.00.00 focuses exclusively on the individual components and accessories. For instance, a sputtering chamber used in a wafer fabrication machine would be classified here as a part, whereas the complete sputtering machine itself would fall under a more specific heading within 8486. Common examples include specialized tooling, fixtures, handling equipment, power supplies, control units, and spare parts, all of which are not machines in themselves but are essential for the functioning of the machines classified in preceding subheadings. The classification of these parts and accessories relies heavily on their direct association with the technology and purpose of the advanced manufacturing equipment described in the chapter notes.
