HS Code for Hard zinc spelter

Hard zinc spelter is classified under HS code 2620.11. This classification is found within Chapter 26, which covers ores, slag, and ash. Specifically, heading 2620 applies to slag, ash, and residues (other than from the manufacture of iron or steel) that contain metals, arsenic, or their compounds. Hard zinc spelter is a specific type of residue that originates from the hot-dip galvanizing process. It is a metallic residue consisting primarily of zinc and iron (a zinc-iron alloy) that settles at the bottom of the galvanizing kettle. Because it is a byproduct intended for the recovery of zinc rather than a finished unwrought metal, it is classified as a residue. The classification under 2620.11 is reserved for residues containing mainly zinc, with the "hard zinc spelter" subheading being the most specific designation. This allows customs authorities to track the trade of metallurgical byproducts separately from primary metal ingots.

Products Included

• Galvanizers' dross (bottom dross)
• Zinc-iron alloy residues from galvanizing baths
• Hard zinc spelter in block or irregular form
• Zinc-rich residues from metal surface treatment

Common Misclassification

Hard zinc spelter is often misclassified under HS code 7901.11, which is for unwrought zinc (99.9% purity). However, spelter is a residue with significant iron content and does not meet the purity standards of heading 7901. It is also sometimes confused with HS code 7902.00 (zinc waste and scrap). The distinction is that 7902 covers scrap from finished zinc products, whereas 2620.11 covers residues arising from industrial metallurgical processes. Finally, it should not be confused with 2620.19, which covers other zinc-containing residues like zinc sludges or filter cakes.

FAQ

What is the HS code for hard zinc spelter?

The specific HS code for hard zinc spelter is 2620.11.

Is hard zinc spelter considered a hazardous waste?

While it is a residue, its status as hazardous waste depends on regional environmental regulations (like the Basel Convention), but for trade, it remains under 2620.11.
