Import Tips & Compliance
• >- Confirm the spent carbon is not classifiable as a catalyst (e.g
• heading 26.20 or 71.12), as that would exclude it from Chapter 38
• Provide a waste analysis showing the adsorbed organic content to support classification
• Verify if the carbon is subject to hazardous waste regulations due to its contaminant load
