Import Tips & Compliance
• Document foundry process to prove industrial metal recovery use; include silver content lab assays
• Avoid retail packaging; bulk shipments reinforce non-waste status
• Test for coarse particles if applicable; pitfall is alloy confusion leading to Chapter 74 misclassification
