Import Tips

• Verify filament tex (≤136) and exact weight ≤185 g/m² via lab testing to avoid reclassification to higher weight subheadings

• Provide mill test certificates confirming uncolored status and mechanical bonding process for customs clearance

• Ensure fabric width documentation >30 cm; common pitfall is mismeasurement leading to 7019.66.20 classification
