Products classified under HTS 2837.19.01.25
Sodium Cyanide Crystals
Sodium cyanide (NaCN) in crystalline form is a highly toxic inorganic salt used primarily in gold mining for extracting gold from ore via cyanidation process. It falls under HTS 2837.19.01.25 as a simple cyanide of an inorganic base (sodium), classified as 'other' cyanides excluding specific types like those of potassium or calcium. This chemically defined compound meets Chapter 28 note requirements for inorganic classification.
Potassium Ferricyanide Powder
Potassium ferricyanide [K3Fe(CN)6] is a red-colored complex cyanide salt used in blueprint photography, analytical chemistry, and as a mild oxidizing agent. Classified under HTS 2837.19.01.25 as a complex cyanide of inorganic bases (potassium and iron), it is 'other' excluding potassium ferrocyanide. Its structure fits Chapter 28 definitions for chemically pure inorganic coordination compounds.
Copper Cyanide Technical Grade
Copper(I) cyanide (CuCN) technical grade powder serves as an intermediate in organic synthesis and copper plating baths for electronics manufacturing. It is classified in HTS 2837.19.01.25 as a simple metal cyanide, fitting 'other' category for inorganic cyanides not specified elsewhere. Chemically defined per Chapter 28 Note 1.
Zinc Cyanide Flakes
Zinc cyanide [Zn(CN)2] in flake form is used in zinc electroplating processes and as a catalyst precursor. This simple inorganic cyanide of zinc base falls under HTS 2837.19.01.25 'other' cyanides, meeting chemical definition requirements without organic substituents.
Barium Cyanide Granules
Barium cyanide [Ba(CN)2] granules find application in chemical synthesis and water treatment. Classified as 'other' cyanides under HTS 2837.19.01.25 for inorganic metal cyanides, distinct from complex varieties.
Silver Cyanide Powder
Silver cyanide (AgCN) powder is essential for silver mirror plating and photographic emulsions. It qualifies under HTS 2837.19.01.25 as a simple cyanide of precious metal base, chemically defined inorganic compound.
Cadmium Cyanide Crystals
Cadmium cyanide [Cd(CN)2] crystals used in cadmium electroplating for corrosion-resistant coatings. Falls in HTS 2837.19.01.25 as other simple cyanides of inorganic (cadmium) base.
Nickel Cyanide for Electroplating
Nickel cyanide [Ni(CN)2] specialized for nickel plating solutions in automotive parts finishing. Classified HTS 2837.19.01.25 'other' cyanides.
Potassium Nickel Cyanide Complex
Tripotassium nickelocyanide [K3Ni(CN)5] complex for bright nickel plating. HTS 2837.19.01.25 as complex cyanide.
Gold Potassium Cyanide
Potassium gold cyanide [KAu(CN)2] for gold electroplating in jewelry. Precious metal cyanide under HTS 2837.19.01.25.
