Products classified under HTS 2841.30.00.00
Sodium Dichromate Dihydrate
Sodium dichromate dihydrate (Na2Cr2O7·2H2O) is the hydrated form of sodium dichromate, a bright orange crystalline powder used primarily in chromium plating and leather tanning. It falls under HTS 2841.30.00.00 as a salt of an oxometallic acid, specifically the dichromate of sodium, meeting the chemical definition for classification in Chapter 28.
Anhydrous Sodium Dichromate
Anhydrous sodium dichromate (Na2Cr2O7) is the water-free crystalline form, highly soluble and used in organic synthesis and pigment manufacturing. Classified under HTS 2841.30.00.00 as it is the pure sodium salt of dichromic acid, an oxometallic acid per Chapter 28 definitions.
Technical Grade Sodium Dichromate
Technical grade sodium dichromate is an industrial-grade powder (typically 98-99% purity) for wood preservation and metal surface treatment. It is classified in HTS 2841.30.00.00 as a chemically defined sodium salt of oxometallic acid, excluding organo-inorganic or excluded preparations.
Laboratory Grade Sodium Dichromate
High-purity laboratory grade sodium dichromate (>99.5%) supplied in small quantities for analytical chemistry and oxidation reactions. Falls under HTS 2841.30.00.00 as a chemically defined inorganic salt per subheading note definitions.
Sodium Dichromate Flakes
Sodium dichromate in flake form for easier handling in industrial dyeing processes, chemically identical to powder but processed for solubility. Classified under HTS 2841.30.00.00 as the form does not change its chemical definition as a sodium oxometallate salt.
Purified Sodium Dichromate Crystals
Purified crystals of sodium dichromate for pharmaceutical precursor synthesis, with impurities below 0.1%. HTS 2841.30.00.00 applies as a pure, chemically defined salt of peroxometallic acid, excluded from organo-inorganic categories.
