Import Tips & Compliance
• Obtain calibration certificates from accredited labs to prove suitability for meter use and avoid reclassification
• Declare electronic components accurately to comply with FCC regulations; include bills of materials for subassemblies
• Avoid common pitfalls by ensuring documentation specifies 'solely for use with 9028 meters' to prevent heading 9033 classification
