HS Code for Zinc slag

Zinc slag is classified under HS code 2620.11, which specifically identifies hard zinc spelter. This classification is situated within Chapter 26, covering ores, slag, and ash. The determination for this code relies on the material being a residue resulting from the manufacture of zinc or from the treatment of zinc-bearing materials. Unlike metal scrap, which is classified in Chapter 79, these residues are typically the byproduct of industrial processes like galvanization. Hard zinc spelter is a specific type of residue that accumulates at the bottom of galvanizing baths, consisting primarily of zinc and iron alloys. Under the General Rules of Interpretation (GRI 1), the classification is governed by the heading texts and section notes. Since heading 2620 excludes slag and ash from iron or steel manufacture (which are directed to 2618 or 2619), but includes those containing mainly zinc, 2620.11 is the most specific subheading for hard spelter. The material must be intended for the recovery of metal or for the manufacture of chemical compounds to qualify under this heading. If the material has been processed into a finished product or is simply scrap metal from a demolished structure, it would fall outside this classification.

Products Included

• Hard zinc spelter
• Zinc dross from galvanization
• Bottom dross from zinc baths
• Zinc-bearing residues from smelting
• Galvanizer's zinc ash

Common Misclassification

Zinc slag is frequently confused with HS code 7902.00, which covers zinc waste and scrap. The distinction lies in the origin: 2620.11 is for industrial residues (byproducts), while 7902.00 is for products that have reached the end of their useful life or manufacturing waste like offcuts. Additionally, granulated slag from iron or steel manufacture is classified under 2618.00, and other residues containing zinc (not hard spelter) may fall under 2620.19.

FAQ

What is the HS code for zinc slag?

The primary HS code for zinc slag, specifically hard zinc spelter, is 2620.11. Other zinc residues are classified under 2620.19.

Is zinc slag considered hazardous for shipping?

Depending on the concentration of heavy metals and local environmental regulations, zinc slag may be classified as a hazardous material under the Basel Convention, though its HS classification remains 2620.11.
