The Peruvian government has issued a sweeping new regulation aimed at eliminating one of the world’s most dangerous industrial pollutants: polychlorinated biphenyls (PCBs). The measure, published under Decreto Supremo Nº 018-2025-SA, sets out strict rules for the identification, handling, and eventual destruction of PCB-contaminated equipment and waste.

What Are PCBs?

Polychlorinated biphenyls are a group of toxic, non-biodegradable chemicals once widely used in electrical transformers, capacitors, and other equipment for their insulating properties. Persistent in the environment, they accumulate in human and animal tissue, causing cancer, immune system damage, and neurological disorders. PCBs were banned globally under the Stockholm Convention on Persistent Organic Pollutants, but many countries, including Peru, still grapple with legacy contamination.

Key Provisions of the Decree

The new Peruvian regulation establishes a framework for sanitary and environmentally sound management of all equipment and waste containing PCBs:

• Inventories Required by 2025: All PCB holders, from power companies to mining firms, must complete inventories of their contaminated equipment and waste by 31 December 2025. These inventories will be reported to the Ministry of Environment and the Environmental Oversight Agency (OEFA)

• Elimination Deadline 2028: PCBs must be fully removed and safely disposed of by 31 December 2028. After 2025, any equipment containing PCBs will automatically be considered hazardous waste and subject to strict controls

• Treatment Standards: The regulation allows for two routes of elimination:

  • With recovery (e.g., chemical dechlorination), where oil and equipment can be reused if PCB concentrations fall below the safe threshold.

  • Without recovery (e.g., high-temperature incineration), ensuring irreversible destruction of the pollutants.

• Bans on Dilution and Trade: PCB-contaminated oils cannot be diluted with clean oils to reduce concentrations. Likewise, the transfer of PCB-containing equipment or waste to third parties is strictly prohibited

• Import and Export Rules: Import of PCB-containing goods is banned. Export of PCB waste will only be permitted when local destruction technologies are unavailable, in line with the Basel Convention on hazardous waste

Enforcement and Penalties

The Ministry of Health, through its environmental health directorate (DIGESA), will oversee occupational health standards related to PCB exposure. Meanwhile, the Ministry of Environment will manage the national PCB database and report progress internationally. Sanctions for violations range from warnings to fines of up to 100 tax units (equivalent to tens of thousands of dollars), as well as the cancellation of operating licenses in severe cases.

Public Health Measures

The decree also mandates that PCBs be added to the official list of occupational diseases within 30 days. Authorities must launch public awareness campaigns to inform communities about the dangers of PCB exposure and the government’s cleanup strategy.

On June 24, 2025, Peru’s Ministry of Health (MINSA) enacted Decreto Supremo N° 007 2025 SA, establishing the Reglamento de la Ley N° 31182. The regulation sets a maximum lead content of 90 parts per million (ppm) in paints and other coating materials, with the aim of protecting public health from lead exposure.

Why It Matters

Lead exposure, especially harmful to children, pregnant women, and other vulnerable groups, leading to developmental delays, neurological damage, and a range of health issues. The new regulation aligns Peru’s standards with international benchmarks used in the EU and the US.

This decree mandates that all paint products manufactured, imported, or sold in Peru comply with new lead concentration thresholds, ensuring safer paints across the market. The regulation also sets requirements for labeling and mandates that manufacturers and importers adjust their formulations to meet the new standard.

Over the coming months, regulatory bodies will begin compliance inspections, and manufacturers and importers must adjust formulas to meet the legal standards.

Next Steps and Enforcement

The decree will enter into force six months after its publication in the official gazette, MINSA, through Digesa (the National Directorate of Environmental Health), will oversee implementation, inspections, and sanctioning of noncompliant paint products. Consumers should soon start seeing labels marking “low lead” or “lead free” paints, offering greater confidence in safety.

Broader Context

This decree operationalizes Law N° 31182, part of ongoing efforts to reduce lead poisoning risks, a public health priority in Peru. Similar regulations exist worldwide, such as in the EU and US, where lead in paints has been restricted for decades. Peru’s move aligns the country with global health and safety standards.

Public Impact

Families and daycare centers can expect safer indoor environments. Construction and paint industries will need to update supply chains and production practices, likely increasing costs short term but improving health outcomes long term. Environmental health professionals can leverage this as a foundation for further monitoring and outreach on lead hazards.

Summary

Peru’s Decreto Supremo N° 007 2025 SA, published today, officially establishes lead content limits in paints through the Reglamento de la Ley 31182. Starting now, paints in Peru must meet new safety standards, with inspections and enforcement mechanisms to follow. It is a positive public health stride toward reducing lead poisoning and follows international best practices.
