Import Tips
• Test and certify weight and colorfastness; fading could challenge 'colored' status under subheading definitions
• Avoid bulk packaging mislabeled as yarn; ensure import docs specify nonwoven fabric form
• Comply with building code certifications for U.S. entry, as roofing materials face additional inspections
