Ferric Chloride Anhydrous
Ferric chloride (FeCl3) in anhydrous form is a chemically defined inorganic iron chloride used primarily as an etching agent in printed circuit board manufacturing and water treatment. It falls under HTS 2827.39.55.00 as 'other chlorides of iron' due to its classification as a simple metal chloride in Chapter 28. This yellow-brown crystalline solid is highly corrosive and hygroscopic.
Ferric Chloride Hexahydrate
Ferric chloride hexahydrate (FeCl3·6H2O) is the hydrated form of iron(III) chloride, appearing as yellowish crystals, used in sewage treatment, pigments, and as a mordant in textiles. Classified under HTS 2827.39.55.00 as an 'other chloride of iron' since hydrates of chemically defined chlorides remain in this heading. It dissolves readily in water to form acidic solutions.
Ferrous Chloride Tetrahydrate
Ferrous chloride tetrahydrate (FeCl2·4H2O), a green crystalline solid, serves as a reducing agent in chemical synthesis, pharmaceuticals, and iron supplements. It is classified in HTS 2827.39.55.00 as 'other chlorides of iron' for its chemically defined inorganic nature under Chapter 28. Highly soluble and oxidizes in air to ferric form.
Iron(III) Chloride Solution 40% Aqueous
A 40% aqueous solution of ferric chloride (FeCl3 in water) used for wastewater coagulation, metal etching, and analytical reagents. Falls under HTS 2827.39.55.00 as a chemically defined iron chloride, where solutions of such compounds remain classified by the salt identity. Typically shipped in HDPE drums due to corrosivity.
Anhydrous Ferric Chloride Granules
Granular anhydrous ferric chloride (FeCl3) for industrial etching of copper in electronics manufacturing and as a catalyst in organic reactions. Classified under HTS 2827.39.55.00 for other iron chlorides meeting chemical definition standards. Dark green-black granules that fume in moist air.
Ferric Chloride for Water Purification
High-purity ferric chloride specifically graded for municipal water and sewage treatment as a coagulant. HTS 2827.39.55.00 applies as a chemically defined iron chloride not excluded by chapter notes. Supplied as liquid or solid with low heavy metal impurities.
