Import Tips

• Verify power rating certification (150-500W) and confirm end-use for ADP machines or 8471 units via commercial invoice to avoid reclassification

• Include FCC Part 15 Class B EMI compliance documentation; test reports from accredited labs prevent customs holds

• Label with exact wattage, efficiency rating, and 'For ADP Equipment' to match subheading; avoid generic 'power supply' descriptions
