Import Tips
• Provide evidence of audio frequency specifications to distinguish from general-purpose ferrites
• Ensure cores are not pre-wound with copper wire, as wound transformers classify differently
• Declare exact dimensions and weight accurately, as ferrites may trigger undervaluation scrutiny
