Import Tips
• Verify chemical purity and provide Certificate of Analysis (CoA) to confirm classification as chemically defined chromate salt per Chapter 28 notes
• Comply with EPA TSCA regulations and REACH-like import notifications due to chromium VI toxicity; include safety data sheets
• Avoid misclassification as a mixture by ensuring >99% purity; common pitfall is bulk shipments labeled without exact composition
