Import Tips & Compliance
• Verify fiber length <0.5mm via microscopy for group 4/5 confirmation; mismeasurement leads to audits
• Include safety data sheets (SDS) showing <1% free silica to avoid dual hazmat classifications
• Preferred carriers experienced in asbestos; pitfall is inadequate dust suppression during transit
