Last updated: April 2026 dataPrecious-metal-bearing ash — the residue from incineration of catalysts, electronic scrap, jewelry manufacturing waste, and similar materials — is a commercially significant secondary recovery feedstock for platinum-group metal and gold refiners. Classified under a single 10-digit line (7112300100), this material is distinct from sweepings and other residues in that it has been subjected to combustion, concentrating the precious metal content in an ash matrix. Canada and Australia are the leading US suppliers, consistent with their active mining and refining sectors that generate catalyst and process ash as a byproduct. Importers should be aware that the precious metal content must be declared accurately, as customs valuation and any applicable export controls in the country of origin may depend on assay documentation.

CBP expects the transaction value to reflect the actual precious metal content. Importers should obtain a certified assay report from an accredited laboratory identifying the type and concentration of precious metals in the ash. This assay, combined with the purchase contract referencing a recognized spot price, forms the basis for a defensible customs valuation and helps avoid undervaluation queries at entry.
Ash containing precious metals is generally not subject to US import licensing as a precious metal feedstock, but certain ash types — particularly those derived from electronic waste or containing elevated levels of heavy metals — may trigger EPA or DOT hazardous-material regulations depending on composition. Importers should obtain a material safety data sheet and confirm whether the ash meets the EPA definition of a hazardous waste or a legitimate secondary material before shipment.
