Import Tips
• Cross-section morphology (concentric vs eccentric) doesn't affect 5503.20.0015 but document for technical validation
• Geotextile end-use common; avoid Chapter 59 classification by proving raw fiber state pre-bonding
• Large bale imports (>500kg) need proper ventilation certification to prevent moisture degradation
