Import Tips
• Submit chemical composition analysis proving S-glass type and filament specs to prevent misclassification as cheaper E-glass
• Document mechanical bonding method; chemical bonded fabrics may require different declaration
• Avoid common error of declaring as 'non-woven'—this is specifically open woven fabric per heading
