Import Tips
• Provide acoustic performance test reports alongside density and impregnation specs to support classification
• Label products clearly as 'bitumen impregnated' to distinguish from untreated fiberboards during customs inspection
• Monitor EU REACH compliance if sourcing from Europe, as it affects US import eligibility
