Exfoliated Vermiculite Insulation from China
Exfoliated vermiculite is a lightweight, expanded form of the mineral vermiculite heated to create airy layers for superior thermal insulation. It falls under HTS 6806.20.00.00 as an exfoliated mineral material used in construction and gardening for heat and sound insulation. This product is expanded through thermal processing, distinguishing it from raw minerals.

Import Tips
• Verify expansion process certification to confirm classification under expanded mineral materials, not raw vermiculite
• Provide lab analysis showing thermal expansion and lightweight properties to customs for smooth clearance
• Avoid misclassification as Chapter 25 minerals by emphasizing end-use in insulation mixtures
