Import Tips
• Test for loose bulk density to distinguish from articles; bulk expanded clays/vermiculite stay in this code
• Provide origin certificates proving non-asbestos contamination to avoid Chapter 68 reclassification
• Declare particle size distribution to comply with USDA phytosanitary rules if used in horticultural mixes
