View full HS code details

Thallium powder is classified under HS code 8112.51, which is situated within Chapter 81 of the Harmonized System, covering "Other base metals; cermets; articles thereof." This specific subheading is reserved for thallium in its unwrought form or as a powder. Thallium is a heavy, bluish-white metal that is highly toxic and used primarily in specialized electronic components, high-refractive-index glass, and infrared optical materials. The classification under 8112.51 is determined by the physical state and chemical composition of the material. "Unwrought" refers to the metal in its primary, unworked state, such as ingots, blocks, or slabs, while "powders" refers to particles of which at least 90% by weight pass through a sieve with a mesh aperture of 1 mm. This classification is strictly for the metal itself. If the thallium is presented as a chemical compound (e.g., thallium nitrate or thallium oxide), it must be classified in Chapter 28. Similarly, if the thallium is in the form of waste or scrap, it is directed to subheading 8112.52. The distinction between 8112.51 and 8112.52 is critical for regulatory compliance, as waste materials often face different environmental and hazardous material transport regulations. For customs purposes, the purity of the thallium is a key factor; it must be a base metal and not an alloy where another metal predominates by weight. The powder form is often produced through electrolytic deposition or mechanical grinding of the unwrought metal. Because thallium is a rare and niche metal, it does not have its own chapter like iron or copper, hence its placement in the "catch-all" Chapter 81 for other base metals. Importers must ensure that the material is not mixed with other substances that would classify it as a chemical preparation under Chapter 38.

Common Misclassification

Thallium powder is often confused with thallium waste and scrap, which is classified under 8112.52. It is also sometimes misclassified under 2825.90 (thallium oxides) or 2620.60 (thallium residues). Code 8112.51 is only for the unwrought metal or pure powder form.
