Import Tips

Include thermal performance specs in docs to justify low-density insulation use, aiding classification verification

Ensure no binders exceed organic substance limits; test reports prevent reclassification as composite materials

Label shipments clearly as 'not surface-covered' to avoid 4411.93 uplift during inspection
