Import Tips

• Verify the fabric meets 'closed woven, plain weave' criteria with documentation on weave type and lamination process to avoid misclassification

• Provide lab tests confirming glass fiber composition and absence of coloring agents, as 'not colored' is key for this subheading

• Ensure mechanically bonded structure is evidenced; common pitfall is classifying non-bonded mats under 7019.31
