Import Tips
• Provide tensile strength test certificates to distinguish S-glass from standard E-glass for proper valuation
• Ensure declaration of filament diameter and twist level (zero for rovings) to prevent reclassification
• Check for anti-dumping duties on specific glass fiber origins; maintain supply chain traceability
