Subheadings
Products classified under Tariff item 2836.60
Barium Carbonate 325 Mesh Powder
Ultra-fine 325 mesh barium carbonate powder used as a flux in pyrotechnic compositions to produce green flames. This chemically defined inorganic carbonate falls under tariff item 2836.60.00 as barium carbonate, meeting the purity and form requirements of Chapter 28.
2836.60.00Barium Carbonate Dense Soda Ash Blend
A blend of barium carbonate with dense soda ash used as a flux in glass batch preparation. The principal component is barium carbonate, and the product is classifiable under this tariff item as barium carbonate, provided the soda ash is incidental and does not alter the essential character.
2836.60.00Barium Carbonate Fine Crystals
Fine crystalline barium carbonate used as a flux in brick and tile production to lower melting points. This is a chemically defined inorganic compound of barium, classifiable under tariff item 2836.60.00 as barium carbonate.
2836.60.00Barium Carbonate for Porcelain Enamel
Barium carbonate used in porcelain enamel coatings for appliances, providing barium oxide fluxing properties during firing. This simple inorganic carbonate of barium is covered by tariff item 2836.60.00, as it is not excluded by Chapter 28 notes.
2836.60.00Barium Carbonate Powder (Technical Grade)
Technical grade barium carbonate powder, a white, odorless inorganic salt used in ceramics for glazing and frit production. It falls under tariff item 2836.60.00 as a chemically defined barium carbonate, meeting Chapter 28 requirements for separate chemically defined compounds.
2836.60.00Calcined Barium Carbonate Granules
Calcined granules of barium carbonate providing controlled release in metallurgical flux applications for steel production. Thermal treatment does not alter the chemical definition, so it remains classifiable under tariff item 2836.60.00 as barium carbonate.
2836.60.00High-Purity Barium Carbonate for Optical Glass
Ultra-high purity barium carbonate (>99.9%) essential for manufacturing high-refractive index optical glass like barium flint. This pure inorganic carbonate is classifiable under tariff item 2836.60.00, per Note 1 to Chapter 28.
2836.60.00Industrial Barium Carbonate for Rat Poison Bait
Barium carbonate formulated for rodenticide baits, a chemically defined inorganic salt toxic to mammals. It remains a simple barium carbonate, not an organo-inorganic compound, so it falls under tariff item 2836.60.00.
2836.60.00Precipitated Barium Carbonate (99% Purity)
Precipitated barium carbonate at 99% purity, a fine, high-quality powder produced via chemical precipitation for specialty glass manufacturing. It is a pure, chemically defined compound classifiable under tariff item 2836.60.00.
2836.60.00Synthetic Barium Carbonate USP Grade
USP-grade synthetic barium carbonate meeting pharmaceutical standards for use in barium sulfate contrast media production. It is a chemically defined compound under tariff item 2836.60.00, as simple carbonates remain in Chapter 28.
