The Government of Japan has opened a public consultation via its official e-Gov platform on proposed amendments to its chemical regulatory framework under the Chemical Substances Control Law (CSCL).

This consultation invites stakeholders to provide feedback on draft regulatory measures aimed at strengthening control of hazardous substances, including persistent organic pollutants such as PFAS.

Key Regulatory Developments

The consultation focuses on proposed updates to the CSCL framework, which governs the manufacture, import, and use of chemical substances in Japan.

Key elements under discussion include:

  • Revision of classification and control measures for hazardous substances
  • Expansion of substances subject to strict regulation (e.g., Class I Specified Chemical Substances)
  • Alignment with international obligations such as the Stockholm Convention

Public consultations are a standard step in Japan’s rulemaking process, allowing industry stakeholders to provide input before final adoption.

Regulatory Context

The proposed changes fall under Japan’s Chemical Substances Control Law (CSCL), which regulates chemicals based on their risk profile:

    Class I Specified Chemical Substances:

  • Persistent, bioaccumulative, and toxic
  • Manufacture and import generally prohibited

    • Class II and other categories:

  • Subject to monitoring, reporting, and risk management

Japan has been progressively strengthening its CSCL framework, particularly for PFAS and other persistent pollutants, aligning with global regulatory trends.

Scope & Threshold Insights

  • Applies to specific listed hazardous substances
  • No tonnage-based threshold — hazard-based regulation

May include:

  • Substance-specific restrictions
  • Import bans for products containing regulated chemicals
  • Technical standards for handling and use

This reflects Japan’s continued shift toward strict lifecycle control of high-risk chemicals.

Substances & Regulatory Focus

While the consultation document outlines draft provisions, it is closely linked to ongoing regulatory actions targeting:

  • PFAS (including PFOA, PFHxS, and related substances)
  • Persistent organic pollutants (POPs)
  • Industrial chemicals with long-term environmental and health risks

Japan has already taken steps to ban or restrict PFAS and similar substances, with further tightening expected through such consultations.

Who is affected?

  • Chemical manufacturers and importers in Japan
  • Exporters supplying chemicals or products into Japan
  • Downstream industries (automotive, electronics, coatings, textiles)
  • Compliance and regulatory affairs teams
  • Companies involved in global supply chains must closely monitor these developments.

Compliance & Market Implications

The consultation signals upcoming regulatory changes that may:

  • Expand restrictions on hazardous substances
  • Increase compliance obligations for manufacturers and importers
  • Require substitution of restricted chemicals
  • Impact product design and supply chains

Early engagement in the consultation process allows companies to influence regulatory outcomes and prepare for future compliance.

Timeline & Next Steps

  • Public Consultation: Open via e-Gov platform (2026)
  • Next Step: Review of stakeholder comments
  • Post-Consultation: Finalization of regulatory amendments
  • Implementation: Expected following official adoption

Japan’s latest public consultation under the CSCL framework reflects its ongoing efforts to strengthen chemical safety and align with global environmental standards. With a focus on hazardous and persistent substances, the proposed amendments are expected to further tighten regulatory controls and increase compliance requirements across industries. Early preparation and active participation in the consultation process will be critical for affected stakeholders.
