Import Tips & Compliance
• >- Provide the CBSA with a detailed description of the FIB technology and its specific application to mask and reticle repair to avoid misclassification as a general microscopy system
• If the workstation includes a scanning electron microscope column, confirm that the principal function remains repair, not inspection, to stay within 8486.40.00
• Keep records of the end-user's semiconductor manufacturing activity in case the CBSA requests proof of use
