HS Code for Thallium residues

HS code 2620.60 covers slag, ash, and residues (other than those from the manufacture of iron or steel) that contain arsenic, mercury, thallium, or their mixtures. This code is specifically intended for materials that are of a kind used for the extraction of these metals or for the manufacture of their chemical compounds. In the hierarchy of the Harmonized System, Chapter 26 deals with ores and the industrial by-products of metallurgical processes. Residues classified here are typically the result of smelting, refining, or chemical treatments where thallium or other toxic metals are concentrated in the flue dust or sludge. Unlike metallic scrap (Chapter 81), these residues are not purely metallic; they are often complex mixtures of oxides, sulfates, or silicates. The classification 2620.60 is unique because it groups thallium residues with those of arsenic and mercury due to their similar environmental risks and extraction methods. To be classified under this code, the residue must be an industrial byproduct. If the material is a deliberate chemical preparation, it would likely fall under Chapter 38. Customs authorities require detailed chemical analysis to confirm the presence of thallium and to ensure the material is not being imported simply for disposal, as waste for disposal is often classified under 3825. The "of a kind used for extraction" clause is a functional requirement; the importer must demonstrate that the material is a viable source for recovering thallium or producing thallium-based chemicals. This code is essential for tracking the international movement of hazardous industrial byproducts that still hold economic value for metal recovery. It excludes any residues containing precious metals in quantities sufficient for extraction, which would move to heading 2620.91.

Common Misclassification

Thallium residues are often misclassified as thallium waste and scrap under 8112.52. However, 8112.52 is for metallic scrap, whereas 2620.60 is for industrial slag and ash. It is also confused with 2617.90 (other ores), but 2620.60 is specific to residues containing thallium.

FAQ

What is the HS code for Thallium residues?

The HS code for thallium residues is 2620.60, covering slag, ash, and residues containing arsenic, mercury, or thallium.

Can this code be used for waste intended for disposal?

No, 2620.60 is specifically for residues used for the extraction of metals or chemical manufacture. Waste intended solely for disposal is generally classified under 3825.
