Import Tips

• Obtain EPA TSCA certification and comply with asbestos import bans or restrictions under 40 CFR Part 763

• Provide mill test reports confirming group 4 grade (fiber length/thickness specs) and chrysotile composition to avoid misclassification

• Declare as hazardous material; common pitfall is failing to specify 'milled fibers' vs. crude, leading to wrong subheading
