Alternative Classifications

This product could be classified differently depending on its characteristics or intended use.

3707.90.60.00Lower: 35% vs 36.1%

If in prepared photographic solutions

When dissolved and put up for photographic use, it becomes a developer chemical under Chapter 37, not pure compound.

2836.20.00Higher: 36.2% vs 36.1%

If misidentified as carbonate salt

Error in composition analysis might place it under carbonates (2836), but cyanide structure defines 2837 per notes.

2843.10.00.00Higher: 40.5% vs 36.1%

If colloidal or precious metal complex

Colloidal gold ferricyanide for special uses falls under 2843 as precious metal compounds.

Import Tips & Compliance

• Provide assay report showing >98% purity to distinguish from mixtures and ensure 2837 classification

• Label packages with UN number 1588 and 'Poison' marking for DOT hazardous material compliance during import

• Avoid bulk packaging over 25kg without stabilizers, as it may trigger reclassification as unstable under 2853
