New PFOS and PFOA Standards Effective April 2026
On June 30, 2025, Japan’s Consumer Affairs Agency (CAA) announced new safety limits for PFOS and PFOA chemicals in sterilized and filtered mineral water. This move targets harmful PFAS substances, aligning with global efforts to reduce these persistent pollutants in consumer products.
Background and Scientific Basis
Earlier in February 2025, Japan notified the World Trade Organization (WTO) of plans to update water quality standards under the Food Sanitation Act. This regulatory change was backed by a risk assessment from the Food Safety Commission of Japan (FSCJ), highlighting potential health risks from PFAS exposure through drinking water.
New Safety Thresholds Introduced
• PFOS Limit: Maximum 0.00005 mg/L
• PFOA Limit: Regulated for the first time, matching international benchmarks
These strict thresholds aim to protect consumers and ensure Japan’s standards keep pace with global scientific findings.
Public Consultation and Timeline
A 60-day public consultation on the proposed limits closed on April 27, 2025. The new PFAS standards will be officially enforced starting April 1, 2026, providing companies ample time to prepare.
Industry Impact and Compliance Steps
Water producers and distributors must:
• Enhance testing procedures to detect PFAS at new limits
• Update quality assurance and labeling practices
• Strengthen supply chain oversight to avoid contamination
Meeting these requirements is critical to maintaining market access and consumer trust.
Significance
Japan’s introduction of PFOS and PFOA limits in mineral water demonstrates a strong commitment to consumer safety and environmental health. Companies should begin adjusting their operations now to ensure smooth compliance ahead of the April 2026 deadline.
