Import Tips
• Document foil as 'minor surface treatment' <5% weight to maintain OSB classification vs composite panels
• Provide radiant barrier performance data (emittance ≤0.05) but emphasize OSB core construction in rulings
• Ensure foil reflectivity certification doesn't imply 'finished article' status triggering Chapter 39 plastics heading
