Thallium waste and scrap represents process residues and off-specification material recovered from industrial operations, including byproduct streams from zinc and lead smelting where thallium naturally concentrates. Because no children tariff lines are provided for this heading in the current US schedule, importers should confirm the applicable 10-digit classification with a licensed customs broker. The extreme toxicity of thallium compounds means that waste and scrap shipments may also trigger EPA hazardous waste import notification requirements under RCRA, separate from customs entry.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Thallium-bearing waste may be subject to EPA Resource Conservation and Recovery Act (RCRA) requirements if it meets the definition of a hazardous waste. Importers should evaluate whether the material triggers RCRA notification obligations and consult with an environmental compliance specialist in addition to a licensed customs broker before shipment.
Thallium accumulates as a trace byproduct in flue dusts and residues from zinc, lead, and copper smelting. Because primary thallium demand is small and geographically concentrated, scrap and byproduct material often crosses borders to reach the few facilities equipped to refine or safely dispose of it, making international trade flows a function of smelter geography and hazardous-material handling capacity.
