Import Tips

Verify the mica is agglomerated or reconstituted, not natural mica, to confirm classification under 6814.10.00.00; provide lab analysis if challenged

Include detailed specifications on support material (e.g

paper) and thickness in commercial invoice to avoid misclassification as articles

Ensure compliance with electrical safety standards like UL for insulation products to facilitate customs clearance
