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
