Import Tips
• Submit manufacturer's spec sheets confirming ≥95% monomer purity to Customs for binding ruling
• Label shipments clearly as 'primary form polyamide-12' to distinguish from finished articles
• Watch for contamination; even minor additives may reclassify under 3908.90.55 as chemically modified
