Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If melted and cast into aluminum waste/scrap
Molten processing changes from residue to Chapter 76 aluminum waste.
If containing mainly other metals like zinc
2620.40 specific to aluminum; other metals use 2620.99.
If primarily chromium-containing
Different metal predominance directs to specific 26xx headings.

Import Tips & Compliance
• Require particle size and metal assay reports; coarse dross (>4.75mm) may need statistical note verification
• Avoid packaging as consumer product; declare for industrial extraction to stay in 2620
