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
