Import Tips
• Submit fiber type certification (S-Glass composition) and weaving specs to CBP for accurate duty assessment
• Avoid common error of declaring weight inaccurately; use calibrated scales for g/m² verification
• Document import as individual fabric rolls, not prepregs, to prevent shift to composite headings
