Import Tips
• Provide span rating documentation (e.g
• 24/16) to demonstrate structural integrity and prevent undervaluation claims
• Check for square-edge vs. tongue-groove; T&G subfloor OSB often requires separate statistical reporting
• Ensure formaldehyde emissions comply with EPA TSCA requirements; non-compliant panels face detention
