KLA-Tencor Teron 640e EUV Reticle Blank Inspector from Mexico
The KLA-Tencor Teron 640e is an extreme ultraviolet (EUV) reticle blank inspection system used to detect buried defects in multilayer blanks before patterning. It uses actinic wavelength inspection, which is critical for 7nm and below semiconductor nodes. This instrument is classified under tariff item 9031.41.00 as it is specifically designed for inspecting reticle blanks used in semiconductor device manufacturing.

Import Tips
• Ensure the EUV inspection capability is clearly documented, as this justifies classification under 9031.41.00 for semiconductor reticle inspection
• The CBSA may ask for proof that the system operates at actinic wavelengths for EUV lithography
• Consider whether the system requires an export permit from the country of origin, as this may affect the import process
