Under TSCA Section 13, importers must file a TSCA certification with CBP at entry. For PCB-containing waste oils at or above 50 mg/kg (line 2710910010), EPA's PCB regulations under 40 CFR Part 761 may also require prior approval or notification depending on the intended disposition. Importers should consult EPA's Office of Pollution Prevention and Toxics and a licensed customs broker experienced in TSCA-regulated materials before shipment.

EPA's TSCA PCB rules impose strict conditions on the storage, disposal, and processing of PCB-containing materials. While certain re-refining or high-temperature incineration activities may be authorized, they require EPA approval and compliance with 40 CFR Part 761 facility standards. The import itself must still clear CBP with a proper TSCA certification, and the receiving facility must hold the appropriate EPA authorization.
