Import Tips
• Include stoichiometric analysis confirming monopotassium oxalate structure to prevent confusion with dipotassium salt
• Ship in moisture-proof containers as compound deliquesces, preventing weight gain that triggers reclassification issues
• Declare exact CAS number 127-95-7 on commercial invoice for customs verification
