Import Tips
• Verify ferrite composition (MnZn or NiZn) through material certification to confirm classification under ferrite subheading
• Include technical specs showing use in transformers/static converters to avoid reclassification as general inductors
• Watch for anti-dumping duties on Chinese-origin ferrites; provide country-of-origin documentation
