Subheadings
Products classified under HTS 2805.19.90
Sodium Metal Ingots
Pure sodium metal in ingot form, an alkali metal used primarily in industrial applications such as chemical synthesis and alloy production. Classified under HTS 2805.19.90 as it is an alkali metal other than sodium in aqueous solution. This subheading covers rare-earth free, non-interalloyed alkali metals like sodium.
Potassium Metal Chunks
High-purity potassium metal supplied in small chunks under inert atmosphere, used in organic synthesis and as a reducing agent. Falls under HTS 2805.19.90 as an alkali metal, not in solution or interalloyed. Excludes rare-earth metals or mercury per Chapter 28 notes.
Lithium Metal Ribbons
Thin ribbon-form lithium metal, an alkali metal used in battery anodes and pharmaceutical intermediates. HTS 2805.19.90 applies to this pure, unalloyed form excluding aqueous or specific solutions. Distinguished from lithium compounds in other chapters.
Cesium Metal Ampoules
Cesium metal sealed in glass ampoules to prevent reaction with air, used in atomic clocks and photoelectric cells. As a pure alkali metal, it fits HTS 2805.19.90 'other' category excluding solutions or alloys.
Rubidium Metal Pellets
Rubidium metal in pellet form, an alkali metal for research in photoelectronics and specialty alloys. Classified in 2805.19.90 as 'other' alkali metals not in solution or specified forms.
Francium Metal Sample
Laboratory-prepared francium metal samples (short-lived), rare alkali metal for nuclear research. HTS 2805.19.90 covers this exotic alkali metal in pure form.
Calcium Metal Granules
Granular calcium metal, an alkaline-earth metal used as a deoxidizer in steel production. Fits 2805.19.90 as 'other' alkali/alkaline-earth metals excluding solutions.
Strontium Metal Rods
Strontium metal rods for pyrotechnics and alloying. Alkaline-earth metal under HTS 2805.19.90.
Barium Metal Powder
Powdered barium metal, alkaline-earth used in vacuum tech. HTS 2805.19.90 classification.
Radium Metal (Depleted)
Depleted radium metal for research. Alkaline-earth, HTS 2805.19.90 if non-radioactive.
