Arsenic-, mercury-, and thallium-bearing ash and residues are among the most tightly regulated secondary materials in international trade, given the acute toxicity of these elements and their potential classification as hazardous waste under both US EPA rules and the Basel Convention. The US schedule separates residues destined solely for arsenic extraction (2620601000) from the broader mixed-metal provision (2620600000), a distinction that can affect both duty treatment and EPA import notification requirements. The Czech Republic is the recorded leading US supplier, likely reflecting specialty metallurgical processing of complex polymetallic concentrates in Central Europe. Importers must carefully assess whether these materials qualify as hazardous waste under RCRA and whether Basel Convention prior informed consent procedures apply before arranging shipment.

Arsenic-bearing residues destined for metal recovery may qualify for a RCRA hazardous waste exclusion if they meet the definition of a 'recyclable material' under 40 CFR Part 261. However, if the material exhibits hazardous characteristics (toxicity, reactivity), an EPA import consent notification under 40 CFR Part 262 Subpart H may be required. The separate 10-digit line 2620601000 — covering residues intended only for arsenic extraction — signals that the intended use is a key classification and regulatory factor. Importers should consult both a licensed customs broker and an environmental compliance attorney before entry.
The United States has not ratified the Basel Convention, but many exporting countries have, and they may require prior informed consent (PIC) procedures before shipping hazardous waste to non-party countries. Additionally, the Minamata Convention on Mercury imposes specific controls on mercury trade and waste that may affect cross-border shipments of mercury-bearing residues. Importers should confirm the exporting country's obligations and obtain any required export authorizations from the foreign competent authority before arranging shipment.
