Import Tips
• Verify R-value certification and fiber composition to confirm classification under mineral wools, avoiding misclassification as plastic foams
• Include safety data sheets (SDS) for respirable fibers in documentation to meet EPA and OSHA import requirements
• Ensure packaging labels indicate non-combustible properties to prevent reclassification as building materials under Chapter 68
