Arsenic-Bearing Copper Smelter Residue
Arsenic-bearing copper smelter residue is a by-product of copper smelting that contains arsenic and various metal compounds. It is used in industry for the extraction of metals or the manufacture of chemical compounds, qualifying under heading 26.20 as slag, ash, or residues containing metals or arsenic. This material is not submitted to processes beyond those normal to the metallurgical industry, ensuring classification under tariff item 2620.99.00.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the residue contains arsenic, mercury, thallium, or their mixtures and is used for extraction of those metals
Subheading note 2 directs such residues to 2620.60.
If the residue is primarily from lead or zinc manufacturing
Heading 26.20 has specific subheadings for lead and zinc residues.
If the material is granulated slag from iron or steel manufacture
Granulated slag is excluded from heading 26.20 and classified under 2618.

Arsenic-Rich Smelter Flue Dust
Arsenic-rich smelter flue dust is collected from non-ferrous metal smelters and contains primarily arsenic with minor metals. It is used for the extraction of arsenic or metals or for the manufacture of chemical compounds, fitting the scope of heading 26.20. The dust is unprocessed and not intended for copper, lead, or zinc recovery, making it classifiable under 2620.99.00.
Battery Recycling Nickel Slag
Battery recycling nickel slag is produced from recycling nickel-metal hydride batteries and contains over 10% nickel. It is used for further metal recovery and is classified under 2620.99.00 as other non-steel industrial residues.
Cemented Tungsten Residue
Residue from cemented tungsten carbide grinding operations, predominantly composed of tungsten compounds. This material falls under tariff item 2620.99.00 as a non-ferrous residue containing metals for industrial recovery, not excluded by Chapter 26 notes.
Hard Metal Alloy Slag
Slag from melting hard metal alloys where tungsten is the dominant component, used in tooling industries. This slag is classified under tariff item 2620.99.00 as a non-ferrous slag containing metals for industrial extraction, not excluded by Chapter 26 notes.
High-Nickel Alloy Foundry Dust
High-nickel alloy foundry dust is collected from foundries melting nickel alloys and contains over 10% nickel by weight. It is suitable for nickel reclamation and is not from iron or steel making, thus classified under 2620.99.00.
High-Titanium Ilmenite Slag
High-titanium ilmenite slag is a byproduct from ilmenite smelting containing over 40% titanium by weight. It is used as feedstock for titanium dioxide production and meets 2620.99.00 criteria as it has low levels of recoverable base metals.
