Import Tips
• Obtain prior import permits from regulatory agencies due to asbestos bans under TSCA; declare end-use as scientific or remediation only
• Include fiber length and purity analysis in documentation to confirm classification as crude amosite vs processed
• Use NIOSH-approved respirators and sealed containers to prevent airborne release during customs inspection
