Products classified under HTS 2836.60.00.00
Barium Carbonate Powder (Technical Grade)
Technical grade barium carbonate powder is a white, odorless inorganic salt used primarily in the ceramics industry for glazing and frit production. It falls under HTS 2836.60.00.00 as a chemically defined barium carbonate, explicitly listed in the chapter notes for Chapter 28 carbonates of inorganic bases.
Precipitated Barium Carbonate (99% Purity)
Precipitated barium carbonate at 99% purity is a fine, high-quality powder produced via chemical precipitation for use in specialty glass manufacturing. Classified under HTS 2836.60.00.00 as it is a pure, chemically defined inorganic carbonate of barium per Chapter 28 notes.
Barium Carbonate Fine Crystals
Fine crystalline barium carbonate is an inorganic compound used as a flux in brick and tile production to lower melting points. It is specifically covered by HTS 2836.60.00.00 as a carbonate of an inorganic base, excluded from organic products per chapter notes.
Industrial Barium Carbonate for Rat Poison Bait
Barium carbonate formulated for rodenticide baits is a chemically defined inorganic salt toxic to mammals, used in pest control products. HTS 2836.60.00.00 applies as it remains a simple barium carbonate, not an organo-inorganic compound per chapter exclusions.
Barium Carbonate 325 Mesh Powder
325 mesh barium carbonate powder offers ultra-fine particle size for pyrotechnics and fireworks fluxing to produce green flames. It qualifies for HTS 2836.60.00.00 as a chemically defined inorganic carbonate, distinct from stabilized organic variants in other headings.
High-Purity Barium Carbonate for Optical Glass
Ultra-high purity barium carbonate (>99.9%) is essential for manufacturing high-refractive index optical glass like barium flint. Classified under HTS 2836.60.00.00 as a pure inorganic carbonate per Note 1 to Chapter 28 definitions.
Barium Carbonate for Porcelain Enamel
Barium carbonate used in porcelain enamel coatings for appliances provides barium oxide fluxing properties during firing. HTS 2836.60.00.00 covers this as a simple inorganic carbonate of barium, not excluded under chapter notes.
Synthetic Barium Carbonate USP Grade
USP-grade synthetic barium carbonate meets pharmaceutical standards for use in barium sulfate contrast media production. It is a chemically defined compound under HTS 2836.60.00.00, as simple carbonates remain in Chapter 28 regardless of purity.
Barium Carbonate Dense Soda Ash Blend
Blended barium carbonate with dense soda ash serves as a flux mixture for glass batch preparation. Principal barium carbonate component keeps it under HTS 2836.60.00.00 as chemically defined, per subheading note.
Calcined Barium Carbonate Granules
Calcined granules of barium carbonate provide controlled release in metallurgical flux applications for steel production. Remains HTS 2836.60.00.00 as thermal treatment doesn't alter chemical definition per Chapter 28.
