HS Code for Chromium residues

Chromium residues are classified under HS code 2620.91. Chapter 26 of the Harmonized System covers ores, slag, and ash. Heading 2620 specifically addresses slag, ash, and residues (other than those from the manufacture of iron or steel) that contain metals, arsenic, or their compounds. These are typically industrial by-products used for the extraction of metals or the manufacture of chemical compounds. Subheading 2620.91 is a specific carve-out for residues containing antimony, beryllium, cadmium, chromium, or their mixtures. This classification is critical because these residues are often subject to environmental regulations and the Basel Convention on the control of transboundary movements of hazardous wastes. The classification applies to materials resulting from industrial processes like electroplating, leather tanning, or chemical manufacturing where chromium is recovered from waste streams.

Products Included

• Chromium-bearing sludge from electroplating
• Galvanic residues containing chromium
• Spent catalysts containing chromium (for metal recovery)
• Filter cakes from chromium chemical production
• Ash from the incineration of chromium-treated materials

Common Misclassification

The most common misclassification is with HS code 2610.00, which is for chromium ores and concentrates. Ores are naturally occurring minerals, whereas residues are the result of industrial processing. Another error involves 2619.00, which covers slag and dross from the manufacture of iron or steel. If the chromium residue comes from a steel mill (like EAF dust), it might be argued under 2619, but 2620.91 is generally preferred for specific metal-bearing residues. Finally, if the residue is simply municipal waste, it would fall under 3825.

FAQ

What is the HS code for chromium residues?

The HS code is 2620.91, which covers slag, ash, and residues containing chromium.

Are chromium residues considered hazardous waste?

In many jurisdictions, yes. While the HS code 2620.91 identifies the material for customs, additional environmental codes (like Basel codes) may be required for transport.
