Import Tips & Compliance
• Distinguish the interferometer from spectrometers (e.g
• FTIR) which fall under 9027.30.00, by providing specifications on its use for displacement measurement
• Ensure the device is not part of a larger measuring system that could be classified under 9031
• Keep records of the intended use (educational or research) for CBSA review
