Import Tips
• Include acoustic performance test reports to support PVB classification and distinguish from standard films
• Ensure documentation shows import in sheet/roll form, not pre-laminated, to avoid glass tariff
• Check for chemical modification notes; unmodified PVB stays here, modified may shift to 'Other'
