Ash & Residues Containing Metals and Metallic Compounds, N.E.S. imports of $5.3M in August 2026 ran 77% below the year-to-date monthly average of $23.2M.
Last updated: August 2026 dataMetallic ash and residues — including spent catalysts, flue dusts, leach residues, and smelter slags — are secondary-recovery materials that serve as feedstock for metal recyclers and refinery operations seeking to recover valuable metals such as vanadium, molybdenum, nickel, and precious metals. Unlike primary ores, these materials often carry environmental characterization requirements: EPA's Resource Conservation and Recovery Act (RCRA) hazardous-waste rules and the Basel Convention's prior-informed-consent procedures can apply depending on the residue's composition and the exporting country. Importers should obtain a detailed chemical analysis of the residue before shipment to determine whether it meets the regulatory definition of a hazardous waste and whether an EPA import notification is required.

EPA requires advance notification and consent for imports of hazardous waste destined for recovery or disposal in the US under RCRA and implementing regulations. Whether a metallic residue qualifies as a hazardous waste depends on its listed or characteristic status — factors such as toxicity, ignitability, and specific chemical content. Importers should obtain a full chemical analysis and consult with an environmental compliance attorney or licensed customs broker before the first shipment.
Spent catalysts from petroleum refining or chemical processing often contain recoverable vanadium, molybdenum, nickel, or platinum-group metals, making them commercially valuable secondary feedstocks. However, they may also contain hydrocarbon residues or heavy metals that trigger RCRA hazardous-waste characterization. Some spent catalysts are explicitly listed as hazardous wastes under EPA rules, requiring specific handling, manifesting, and import-consent procedures distinct from non-listed metallic slags or flue dusts.
