Import Tips
• Provide photomask/reticle-specific calibration data to distinguish from general optical comparators
• Ensure documentation excludes technical use in machines per Chapter 90 note (a) to prevent reclassification
• Label as 'other' wafer inspection to match 9031.41.0060; avoid broad 'optical instrument' descriptions
