Products classified under HTS 2837.20.10.00
Potassium Ferricyanide Powder
Pure potassium ferricyanide (K3[Fe(CN)6]) in fine powder form, a chemically defined complex cyanide used primarily as a reagent in analytical chemistry labs. It falls under HTS 2837.20.10.00 as a complex cyanide of inorganic bases, specifically potassium ferricyanide, per Chapter 28 notes. This yellow crystalline compound is essential for qualitative analysis and as an oxidizing agent.
Technical Grade Potassium Ferricyanide
Technical grade potassium ferricyanide crystals for industrial blueprinting and photography processes. Classified under HTS 2837.20.10.00 as it is a specific complex cyanide, chemically defined per subheading note to 2852 and Chapter 28. Used in cyanotype printing for its light-sensitive properties.
ACS Reagent Potassium Ferricyanide
American Chemical Society (ACS) grade potassium ferricyanide for high-precision titrations and spectroscopy. This pure, chemically defined complex cyanide is explicitly under HTS 2837.20.10.00 as potassium ferricyanide. Meets stringent lab standards for trace metal analysis.
Potassium Ferricyanide Lab Crystals
Large crystal form of potassium ferricyanide for educational lab demonstrations of redox reactions. Falls under HTS 2837.20.10.00 as a complex cyanide, pure and chemically defined. Iconic for 'Prussian blue' formation experiments.
