Import Tips
• Submit FDA Drug Master File references and ensure batch testing certificates confirm salt identity via HPLC
• Declare exact CAS number (specific to cathine sulfate) on commercial invoice to prevent reclassification
• Avoid bulk packaging over 25kg without stabilizers, as chapter notes limit additions to those for safety/transport
