Products classified under HTS 2844.43.00.10
Cobalt-60 Radioactive Source
A sealed capsule containing cobalt-60 isotope used primarily for industrial radiography to inspect welds and materials for defects. It falls under HTS 2844.43.00.10 as it consists of the cobalt-60 isotope with specific radioactivity exceeding 74 becquerels per gram, meeting the definition for radioactive isotopes in heading 2844. This product is chemically defined and used in non-medical gamma irradiation applications.
Co-60 Gamma Irradiator Source
High-activity cobalt-60 encased in stainless steel for use in self-contained gamma irradiators for sterilizing medical equipment and food products. Classified under HTS 2844.43.00.10 due to its exclusive cobalt-60 composition and high specific radioactivity as a radioactive isotope per Chapter 28 notes. Excludes mixtures with other isotopes.
Cobalt-60 Radiography Pencil
A portable, pencil-shaped sealed source of cobalt-60 gamma rays designed for non-destructive testing in field radiography of pipelines and structures. It qualifies for HTS 2844.43.00.10 as a compound/isotope of cobalt-60 with defined radioactivity, distinct from alloys or residues. Used exclusively for industrial imaging.
Sealed Cobalt-60 Calibration Source
Low-activity sealed disc of cobalt-60 used to calibrate radiation detectors and survey meters in laboratory settings. Falls under HTS 2844.43.00.10 for its pure cobalt-60 isotopic content meeting Chapter 28's chemically defined radioactive compound criteria. Not for therapeutic use.
High-Specific-Activity Co-60 Isotope
Purified cobalt-60 isotope in metallic form with activity >74 Bq/g for research in nuclear physics and material studies. Classified precisely under HTS 2844.43.00.10 per notes defining isotopes as individual nuclides or enriched mixtures of cobalt-60 only. Excludes alloys or compounds with other elements.
Co-60 Brachytherapy Seed
Tiny sealed cobalt-60 seeds for temporary implantation in brachytherapy procedures, though less common than Ir-192. Meets HTS 2844.43.00.10 as a radioactive compound of cobalt-60 with defined high specific activity per heading 2844 note (e). Used in oncology.
Industrial Co-60 Exposure Source
Large-scale cobalt-60 source assembly for continuous exposure in industrial sterilization facilities processing plastics and spices. HTS 2844.43.00.10 applies to this cobalt-60 only element/isotope with requisite radioactivity, excluding cermets or mixtures. Engineered for high-volume gamma processing.
Research-Grade Cobalt-60 Compound
Chemically defined cobalt-60 chloride (Co-60Cl2) solution for tracer studies in metallurgy and environmental science. Classified under HTS 2844.43.00.10 as a compound of the cobalt-60 isotope per Chapter 28 note 2(c), with specific radioactivity >74 Bq/g. Supplied in dilute aqueous form.
