Import Tips
• Verify mica purity through lab testing to avoid misclassification as waste under 2525.20
• Provide geological origin certificates to confirm crude status and prevent duties on processed forms
• Declare exact thickness and sheet dimensions; exceeding split block tolerances shifts to other subheadings
