Import Tips
• Verify purity certificate (typically 99%+ Fe(CN)6 content) to confirm classification as chemically defined under Chapter 28 Note 1
• Include Safety Data Sheet (SDS) and ensure REACH/ TSCA compliance for chemical imports to avoid FDA or EPA holds
• Declare exact CAS number (13746-66-2) on commercial invoice to prevent misclassification as mixtures
