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
