Import Tips
• Include span rating documentation (e.g
• 24/16, 32/16) from accredited testing agencies to validate structural OSB status
• Ensure panels meet APA Exposure 1 rating requirements if marketed for exterior sheathing to avoid misclassification
• Declare exact resin content and wood species origin, as high binder ratios could trigger reclassification concerns
