PCBs in Transformers: The December 31, 2025 Deadline Is Confirmed

Friday August 22nd, 2025

The Italian Ministry of the Environment has removed all doubt: by December 31, 2025, all equipment containing PCBs in concentrations greater than 0.005% (50 mg/kg) and with a volume > 0.05 dm³ must be taken out of service, decontaminated, or disposed of.

This clarification came in response to an official inquiry from Confindustria, Italy’s main industry association. It confirms an interpretation that Sea Marconi has long supported in its technical and regulatory analyses: this is the final, non-extendable deadline.

In short, any equipment still in operation with contaminated fluids above the threshold must be identified, classified, and managed in compliance with EU regulation (EU Regulation 2019/1021).

Although some past national regulations seemed to allow for more flexible conditions, it is now clear: the December 31, 2025 deadline takes precedence over all.
