Import Tips

• 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
