HS code for Scrap thallium: 8112.52
Thallium, waste and scrap.
Classification of scrap thallium under HS 8112.52
Thallium waste and scrap are classified under HS code 8112.52. Thallium is a heavy, soft metal categorized under "Other base metals" in Chapter 81 of the Harmonized System. Heading 8112 specifically covers beryllium, chromium, germanium, vanadium, gallium, hafnium, indium, niobium, rhenium, and thallium. The subheading 8112.52 is dedicated to the waste and scrap of thallium. Classification is based on the material being metallic thallium that is no longer usable for its original purpose due to breakage, wear, or manufacturing defects. Thallium scrap often originates from the production of optical lenses, semiconductors, or chemical catalysts. Because thallium and its compounds are highly toxic, the classification and movement of its scrap are strictly regulated. The material must be in metallic form; thallium compounds or residues that are not purely metallic would fall under different headings in Chapter 28 or 38.

Codes often confused with 8112.52
Common mistake. Thallium scrap is often misclassified under HS code 8112.51, which is for unwrought thallium and powders. Unwrought metal refers to primary production forms like ingots or blocks, whereas 8112.52 is for secondary waste. Another common mistake is classifying thallium oxides or salts under this code; those should be classified in Chapter 28 (e.g., 2825.90 for other metal oxides).
Top exporters and importers of HS 811252 (the code used for scrap thallium), 2025
In 2025, the largest exporter of HS 811252 (the code used for scrap thallium) in UN Comtrade data was Israel, with 100% of world exports; the largest importer in UN Comtrade data was Norway, with 98% of world imports. Austria reports $415M of its chapter 81 exports without product detail (confidential), so it may also belong among the top exporters.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. 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).
