Import Tips
• Include alkali resistance certification (ZR rating) to justify AR-glass classification over standard types
• Declare end-use in construction composites; bulk packaging affects Form 7501 line descriptions
• Watch for fiber blooming during shipping; proper container ventilation prevents customs holds
