Import Tips
• Verify the ferrite is specifically labeled or documented for transformer use to avoid reclassification as general inductors
• Include technical datasheets showing frequency range and magnetic properties to confirm HTS 8504.90.96.10 applicability
• Check for RoHS compliance and provide material safety data sheets, as ferrites may contain hazardous substances
