Import Tips
• Verify purity and chemical identity via Certificate of Analysis to confirm classification as a chemically defined salt under Chapter 28
• Ensure SDS and proper hazardous material labeling if shipped in quantities triggering DOT regulations; common pitfall is mislabeling as fertilizer
• Obtain EPA registration if destined for agricultural use to avoid customs holds
