Import Tips
• Include pressure rating certifications and SDR (standard dimension ratio) specs to prove rigid construction
• Label shipments clearly as 'rigid polyethylene pipes of ethylene polymers' to match HTS description
• Watch for blending with other monomers over 5%, which may require predominant monomer analysis under subheading notes
