2612.20.00.00 - Thorium ores and concentrates

This HTS category, 2612.20.00.00, specifically encompasses thorium ores and their concentrated forms. Thorium, a radioactive metallic element, is often found in mineral deposits such as monazite sands. This classification covers the raw ore as extracted from the ground, as well as any processed material where thorium has been physically or chemically separated to increase its concentration, making it suitable for further industrial or nuclear applications.

Within the broader heading of "Uranium or thorium ores and concentrates" (2612), this subcategory is distinct from its sibling, 2612.10.00.00, which is exclusively for uranium ores and concentrates. While both relate to naturally occurring radioactive elements in ore form, the defining characteristic for classification here is the primary presence and focus on thorium, rather than uranium. This distinction is crucial for customs authorities to accurately apply duties and regulations specific to each element.

As this is a leaf node in the HTS structure, there are no further subcategories. Therefore, classification under 2612.20.00.00 is final. Importers and exporters should ensure that the material being declared is predominantly thorium-bearing ore or a concentrate thereof, and not primarily uranium-bearing. Documentation or assay reports may be required to substantiate the composition and verify the correct classification.
