Import Tips

• Test and document porosity/density for acoustic claims; CBP may require proof it's not rigid insulation

• Ensure no perforations or fabric facing, which could shift to 4418 joinery or 7019 glass wool analogs

• Fire rating documentation helpful for building code compliance in US imports
