Import Tips
• Ensure the interferometer's specific use for phase-shift photomask measurement is documented to support classification under 9031.41.00
• The CBSA may require technical specifications showing angstrom-level precision
• If the system includes analysis software, confirm whether it is a separate import or part of the system's value
