Import Tips
• Obtain UL or FM approvals pre-import for fire-rated claims to expedite FDA/USDA equivalence if applicable
• Specify 'unfaced' on commercial invoice; foil or kraft facing often reclassifies to 4811 or 6812
• Monitor formaldehyde emissions certification under CARB rules for U.S. market entry
