Products classified under HTS 2805.19.20.00
Barium Metal Ingots
High-purity barium metal cast into ingots, used primarily in the production of alloys and chemicals. This elemental barium falls under HTS 2805.19.20.00 as it is an alkaline-earth metal in its pure form, not interalloyed or intermixed. Typically supplied in vacuum-sealed packaging to prevent oxidation.
Barium Metal Rods
Cylindrical barium rods in unworked form, ideal for machining into components or evaporation sources in vacuum deposition. Classified under HTS 2805.19.20.00 as pure alkaline-earth metal barium. Purity levels typically 99%+ to meet industrial standards.
Barium Wire (99.5% Purity)
Drawn barium wire in coils, used in specialty alloys and research applications. Falls under HTS 2805.19.20.00 for pure alkaline-earth barium metal in unworked drawn form. Diameter typically 1-5mm.
Research-Grade Barium Chunks
Irregular chunks of 99.99% pure barium for laboratory research and small-scale alloying. HTS 2805.19.20.00 covers this high-purity elemental alkaline-earth metal. Supplied in argon-filled ampoules.
High-Purity Barium Granules
Granular barium metal (99.9% purity) for use in pyrotechnics, getter alloys, and chemical synthesis. HTS 2805.19.20.00 applies to this alkaline-earth metal in granular form, excluding alloys or compounds. Stored under mineral oil to inhibit air/moisture reaction.
Barium Evaporation Pellets
Small barium pellets designed for thermal evaporation in thin-film coating applications like vacuum systems. Pure elemental barium under HTS 2805.19.20.00 as alkaline-earth metal. High vacuum compatibility due to getter properties.
