Import Tips
• Submit acoustic performance certifications (e.g
• NRC ratings) to substantiate insulation use at customs
• Avoid packaging that suggests finished flooring; such could be reclassified under Chapter 45 flooring provisions
• Confirm no binding substance makes it resemble natural cork under Chapter 45 heading 4501
