Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If catalysts remain supported/reusable
Supported catalysts of base metals are in Chapter 38; only fully spent waste goes to Chapter 81.
If roasted antimony roasting residues
Roasted antimony concentrates/waste classified as metal residues in Chapter 26.

Import Tips & Compliance
• Classify based on original form; spent catalysts may qualify under 3815 if still functional for chemical reaction
• Provide spent catalyst deactivation certificates to avoid hazardous waste surcharges
• Monitor arsenic impurities common in catalyst scrap, requiring additional testing under TSCA
