Products classified under HTS 2833.27.00.00
Barium Sulfate Powder (Precipitated)
High-purity precipitated barium sulfate (BaSO4) used as a white pigment in paints, coatings, and plastics. It falls under HTS 2833.27.00.00 as a chemically defined sulfate of barium, specifically classified as 'other sulfates of barium' per Chapter 28 notes.
Blanco Barium Sulfate Pigment
Synthetic barium sulfate pigment known as 'Blanco' or permanent white, used in high-end paints and artist oils for opacity. It is a chemically defined barium sulfate under HTS 2833.27.00.00, distinguished from natural barite by precipitation process.
Barium Sulfate Lithopone Precursor
High-assay barium sulfate used in lithopone production (co-precipitated with zinc sulfide for white pigments). Classified as pure barium sulfate under HTS 2833.27.00.00 before complexing.
Ultra-Fine Barium Sulfate for Batteries
Nano-grade barium sulfate additive for lead-acid battery separators to improve insulation and reduce sulfation. A chemically defined compound classified in HTS 2833.27.00.00.
Barium Sulfate USP Grade
Pharmaceutical-grade barium sulfate used as a radio-opaque contrast medium in X-ray imaging like CT scans and barium swallows. Classified under HTS 2833.27.00.00 as a pure, chemically defined sulfate of barium meeting Chapter 28 Note 1 criteria.
Barytes Precipitated Filler Grade
Micronized precipitated barium sulfate used as a functional filler in rubber, plastics, and tires for reinforcement and opacity. Falls under HTS 2833.27.00.00 as a chemically defined inorganic compound of barium.
Pharmaceutical Barium Meal Suspension Base
Sterile barium sulfate powder base for preparing oral contrast suspensions in gastrointestinal X-rays. Meets USP standards as chemically defined barium sulfate under HTS 2833.27.00.00.
