Import Tips & Compliance
• Include FR test reports (e.g
• NFPA 701) as supporting docs but they don't change fiber classification
• Specify if FR is inherent vs topical treatment to address potential chemical content questions
• Segregate FR fibers from standard polyester during shipping to prevent cross-contamination claims
