Products classified under HTS 2852.10.90.00
Mercuric Chloride
Mercuric chloride (HgCl2), also known as corrosive sublimate, is a white crystalline inorganic compound of mercury used in laboratory reagents and as a fungicide. It falls under HTS 2852.10.90.00 as a chemically defined compound of mercury, excluding amalgams, not specified elsewhere in the subheading. This classification aligns with Chapter 28 notes defining chemically defined mercury compounds.
Mercuric Sulfate
Mercuric sulfate (HgSO4) is a toxic white powder used in analytical chemistry and gold extraction processes. Classified under HTS 2852.10.90.00 as a chemically defined inorganic mercury compound outside specific subheadings. Meets Chapter 28 Note 1 criteria for single mercury salt compounds.
Mercuric Oxide Red
Red mercuric oxide (HgO) is a scarlet powder used in battery production and as a chemical reagent. It qualifies for HTS 2852.10.90.00 as a chemically defined mercury oxide compound not covered by other specific mercury subheadings. Distinguished from yellow form by particle size and color.
Mercuric Iodide
Mercuric iodide (HgI2) appears as a bright red crystalline powder, changing to yellow when heated, used in photography and medicine. Falls under HTS 2852.10.90.00 as a chemically defined mercury halide compound. Excluded from amalgams per heading exclusions.
Mercuric Nitrate
Mercuric nitrate (Hg(NO3)2) is a colorless deliquescent salt used as a catalyst and analytical reagent. Classified in HTS 2852.10.90.00 as other chemically defined mercury compounds meeting Chapter 28/29 note criteria. Highly corrosive and light-sensitive.
Mercuric Acetate
Mercuric acetate (Hg(CH3COO)2) is a white crystalline organomercury compound used in organic synthesis. Though organic, it qualifies under HTS 2852.10.90.00 per subheading note including organic mercury compounds chemically defined. Excluded if meeting Chapter 29 complex criteria elsewhere.
Mercuric Cyanide
Mercuric cyanide (Hg(CN)2) is a highly toxic white powder used in gold mining and electroplating. It is classified under HTS 2852.10.90.00 as a chemically defined mercury compound, distinct from inorganic base cyanides in 2837. Extreme poison requiring special handling.
Mercuric Thiocyanate
Mercuric thiocyanate (Hg(SCN)2) produces the dramatic Pharaoh's serpent reaction and is used in pyrotechnics. Falls under HTS 2852.10.90.00 as other chemically defined mercury compounds. White powder highly sensitive to friction.
Dimethylmercury
Dimethylmercury ((CH3)2Hg) is an extremely toxic volatile organomercury compound used in research. Classified under HTS 2852.10.90.00 as chemically defined organic mercury compound per subheading note. Colorless liquid penetrates skin rapidly.
Phenylmercuric Acetate
Phenylmercuric acetate (C6H5HgOOCCH3) is an organomercury fungicide and slimicide used in paints. HTS 2852.10.90.00 covers it as chemically defined organic mercury compound not excluded by Chapter 29 notes. White to pale yellow powder.
Mercuric Bromide
Mercuric bromide (HgBr2) is a white crystalline compound used in photography and medicine. Classified HTS 2852.10.90.00 as chemically defined mercury halide. Soluble in water, toxic by ingestion.
Mercurous Nitrate
Mercurous nitrate (Hg2(NO3)2) is a colorless toxic salt used in analytical chemistry. Falls under HTS 2852.10.90.00 as chemically defined mercury compound (Hg+ oxidation state). Light-sensitive and explosive when dry.
Ethylmercury Chloride
Ethylmercury chloride (C2H5HgCl) is an organomercury compound used in organic synthesis research. HTS 2852.10.90.00 per subheading note for chemically defined organic mercury compounds. Colorless crystals, highly toxic.
Mercuric Phosphate
Mercuric phosphate (Hg3(PO4)2) is a yellow powder used as analytical reagent. Classified HTS 2852.10.90.00 as other chemically defined mercury compound. Insoluble in water, highly toxic.
