Import Tips
• Provide engineering specs showing intended magnetization and end-use to distinguish from finished cores
• Include heat treatment certifications, as ferrite properties depend on sintering processes
• Label clearly as 'unmagnetized blanks' to prevent confusion with ready-to-use transformer parts
