Heading 2620

Slag, ash and residues (other than from the manufacture of iron or steel), containing arsenic, metals or their compounds

36 declarable lines

Heading 2620 covers slag, ash and residues that contain arsenic, metals or their compounds, other than slag and waste from the manufacture of iron or steel. The heading splits first by the metal that predominates by weight, with subheadings for zinc, lead, copper, aluminum, arsenic-mercury-thallium mixtures, and a residual group for antimony, beryllium, cadmium, chromium, vanadium, tungsten and other materials. The six-digit subheadings are then split further into statistical lines that report the copper, lead, zinc, silver or gold content.

Products in this heading

  • Hard zinc spelter
  • Zinc dross and zinc skimmings
  • Leaded gasoline tank sludges
  • Copper-bearing ash and refinery residues
  • Aluminum slag carrying vanadium
  • Tungsten-bearing residues from chemical processing
  • Slag containing more than 40% titanium by weight
  • Residues containing silver or gold from metal recovery

How to choose the right subheading

  • Identify the metal that predominates by weight, since that picks the zinc, lead, copper, aluminum or arsenic group.
  • Confirm the material is a slag, ash or residue and not an ore or concentrate, and not from iron or steel manufacture.
  • Check whether the goods contain arsenic, mercury or thallium and whether they are used to extract those metals or make their compounds.
  • If no specific metal group applies, decide between the antimony-beryllium-cadmium-chromium line, the vanadium, tungsten and nickel lines, and the residual lines.
  • Pick the statistical line that reports the copper, lead, zinc, silver or gold content of the shipment.

Often confused with

  • Slag, dross and scalings from the manufacture of iron or steel

    Heading 2620 expressly excludes slag and ash from iron or steel manufacture.

  • Ash and residues from the incineration of municipal waste

    Municipal waste incineration ash is named in heading 2621.

    Heading 2621
  • Precious metal ores and concentrates

    Unprocessed ores and concentrates stay in the chapter 26 ore headings, not the residue heading.

    Heading 2616
  • Vanadium ores and concentrates

    Vanadium ore is classified as an ore; only vanadium-bearing slag and residues fall in 2620.

    Heading 2615
  • Unwrought zinc ingots made from remelted dross

    Once the metal is recovered and cast into ingots it is classified as unwrought metal, not as residue.

    Heading 7901

Frequently asked questions

What is the HTS code for zinc dross and zinc skimmings?

Zinc dross and zinc skimmings are classified under 2620.19.30.00. The general (MFN) rate for that line is Free.

What is the duty on residues used to extract arsenic?

Residues of a kind used only for the extraction of arsenic or the manufacture of its chemical compounds fall under 2620.60.10.00. The general (MFN) rate is 5%.

How do I classify copper-bearing slag and ash?

Goods containing mainly copper go in subheading 2620.30, and the copper content is reported under 2620.30.00.10. The general (MFN) rate for that line is Free.
