Aluminum Smelter Bauxite Residue (Red Mud)
Red mud is the alkaline waste residue generated from the Bayer process in aluminum production, containing mainly aluminum compounds along with arsenic and other metals like iron and titanium. It falls under HTS 2620.40.0060 as slag and residues (not from iron/steel) containing mainly aluminum, used for metal extraction or chemical compound production. Excludes municipal waste ash per chapter notes.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If derived from municipal waste incineration
Chapter note excludes municipal waste ash/residues from 2620, directing them to heading 2621 for incineration residues.
If processed into pure aluminum oxide
Further refinement into chemical compounds like artificial aluminum oxide shifts classification from residues to finished chemicals in Chapter 28.

Import Tips & Compliance
• Verify assay quantity of metal content without deductions for accurate statistical reporting per statistical notes
• Provide documentation certifying industrial use for metal extraction or chemical manufacture to avoid reclassification
• Ensure residues are not from municipal waste incineration, as those fall under 2621; common pitfall is mislabeling waste types
