Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If arsenic content is significant and the sludge is used for arsenic extraction
Subheading 2620.60 covers slag, ash and residues containing arsenic, mercury, thallium or their mixtures.
If the sludge contains mainly lead but not from leaded gasoline or anti-knock compounds
This subheading covers other lead-containing slag, ash and residues not specifically defined as leaded gasoline sludge.

Import Tips & Compliance
• Ensure the sludge is not mixed with municipal waste incineration ash, which falls under heading 26.21
• Provide a certificate of analysis showing lead content and silver assay to support classification
• Check if the shipment requires an import permit under the Canadian Environmental Protection Act, as lead-containing residues may be regulated
