8543.70.20.00 - Physical vapor deposition apparatus 🖩

This HTS category, 8543.70.20.00, specifically covers apparatus designed for the physical vapor deposition (PVD) of materials. PVD is a broad range of vacuum deposition methods used to deposit thin films of a material onto a substrate. These systems utilize various techniques, such as sputtering or evaporation, to vaporize a source material and then condense it as a thin solid film on the target surface. Examples include equipment for creating coatings on semiconductors, optical lenses, or decorative finishes.

It is important to distinguish this category from its siblings. For instance, sibling categories may cover electrical synchros, transducers, flight data recorders, or even electric luminescent lamps. The defining characteristic of goods under 8543.70.20.00 is their primary function as machinery for the physical deposition of material in a vaporized state, rather than their use as signaling devices, recording instruments, or light sources.

As this is a leaf node within the HTS structure, there are no further subcategories to introduce. Classification within this specific code is determined by the apparatus's core function of performing physical vapor deposition, irrespective of the specific PVD technique employed (e.g., sputtering, evaporation, ion plating) or the materials being deposited. The apparatus must be specifically designed and utilized for this deposition process to be classified here.
