HS code for Unwrought thallium: 8112.51
Thallium and articles thereof, unwrought thallium, powders.
Classification of unwrought thallium under HS 8112.51
Unwrought thallium is classified under HS code 8112.51. This classification is governed by the General Rules for the Interpretation of the Harmonized System (GRI), specifically GRI 1, which states that classification is determined by the terms of the headings and any relative section or chapter notes. Chapter 81 covers "Other base metals; cermets; articles thereof." Within this chapter, heading 8112 is reserved for metals like beryllium, chromium, germanium, vanadium, gallium, hafnium, indium, niobium, rhenium, and thallium. The subheading 8112.51 specifically addresses thallium in its primary, unworked state, which includes powders and unwrought forms such as ingots or blocks. The term "unwrought" generally refers to metals that have been produced in primary forms by casting, sintering, or similar processes, but have not yet been rolled, forged, drawn, or extruded into specific shapes. Proper classification requires verifying that the material has not undergone further processing that would move it into the "articles" category (8112.59).

Codes often confused with 8112.51
Common mistake. Unwrought thallium is frequently confused with thallium waste and scrap, which is classified under HS code 8112.52. The distinction lies in the origin of the material; 8112.51 is for primary metal, whereas 8112.52 is for material recovered from used articles or manufacturing waste. Another common error is using 8112.59, which is reserved for "other" articles of thallium that have been further worked, such as wires, sheets, or tubes. Additionally, thallium compounds (like thallium sulfate) should not be classified here; they belong in Chapter 28 under inorganic chemicals, specifically 2852.10 or 2852.90 depending on the composition.
Top exporters and importers of HS 811251 (the code used for unwrought thallium), 2025
In 2025, the largest exporter of HS 811251 (the code used for unwrought thallium) in UN Comtrade data was the United States, with 98% of world exports; the largest importer in UN Comtrade data was China, with 52% of world imports.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
