Photoresist Spray Coater for PCB Manufacturing
This mechanical appliance precisely sprays liquid photoresist onto PCB substrates to create uniform photoresist layers essential for the photolithography process in printed circuit manufacturing. It is designed solely for high-precision dispensing in cleanroom environments used for printed circuits. Classified under HTS 8424.89.10.00 due to its principal use in projecting liquids for PCB fabrication.
Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If adaptable for general industrial spraying beyond printed circuits
Equipment with multi-purpose nozzles or adjustable settings for non-PCB uses falls under general mechanical spray appliances.
If imported as replacement parts rather than complete machines
Spray nozzles or pumps classified separately as machines/parts for manufacture of semiconductors or PCBs.
If includes integrated wafer/PCB inspection optics
Apparatus with optical testing components for sprayed layer thickness shifts to chapter 90 for physical/chemical analysis instruments.
