Import Tips
• Include calibration certificates traceable to NIST or equivalent for duty-free scientific instrument consideration
• Specify exact tolerance grades (e.g
• Grade 00) and material (carbide-tipped steel) in commercial invoice
• Import in protective cases labeled for specific micrometer models to avoid general gauge classification
