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
