Agglomerated Mica Insulation Sheets from China

These are plates and sheets made from agglomerated or reconstituted mica, often backed with paper support, used primarily for high-temperature electrical insulation in motors and transformers. They fall under HTS 6814.10.00.00 as they are specifically plates, sheets, or strips of agglomerated mica, whether or not on a support. The product provides dielectric strength and thermal resistance essential for industrial applications.

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
