Import Tips
• Verify product dimensions do not exceed 61 cm width and confirm mineral wool composition via lab testing to avoid reclassification
• Include safety data sheets (SDS) documenting non-asbestos content and fire ratings for U.S. customs clearance
• Label packages clearly with R-value, dimensions, and 'for insulation use only' to prevent misclassification as finished articles
