Import Tips
• Include manufacturer certificates confirming aramid type (e.g
• Twaron) and high tenacity metrics exceeding standard nylon thresholds
• Declare exact denier and filament count accurately, as discrepancies can lead to audits or reclassification
• Ship in industrial bulk packaging to maintain 'not put up for retail sale' status and avoid higher duties
