Import Tips
• Verify fiber diameter and twist specifications to confirm classification as roving under 7019.12, avoiding misclassification as yarn
• Provide manufacturer certifications for E-glass composition (silica content) to comply with Chapter 70 notes on glass fibers
• Ensure proper declaration of intended end-use to prevent reclassification during customs review
