Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing thiocyanates or as double salt
Complex salts with thiocyanates or other ligands fall under 2842 per Chapter Note 6, shifting from simple ferricyanide.
If diagnostic reagents in kits
Prepared as lab diagnostic kits or with additives, it becomes a reagent composition under 3822, not a pure compound.
If used as inorganic pigment
When formulated as luminophore or pigment for dyes/paints, it moves to Chapter 32 per Chapter Note 3(e).

Import Tips & Compliance
• 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
