Import Tips
• Verify purity and ensure Certificate of Analysis confirms it meets chemically defined inorganic compound standards per Chapter 28 notes
• Provide safety data sheets (SDS) due to corrosive nature; common pitfall is inadequate hazmat labeling leading to CBP holds
• Confirm not mixed with organic substances, as that could shift to Chapter 29
