Japan Cabinet Approves CSCL Enforcement Order Amendment Designating LC-PFCA, Chlorpyrifos and MCCP as Class I Substances
Japan has approved an amendment to the Chemical Substances Control Law (CSCL) Enforcement Order to classify LC-PFCA and related substances, chlorpyrifos and medium-chain chlorinated paraffins as Class I specified chemical substances from late 2026. This will tighten import bans and handling rules for affected chemicals and products, meaning suppliers into Japan must identify PFAS and chlorinated paraffin uses in lubricants, wood preservatives and firefighting foams and plan substitution and compliance ahead of the November 2026 start date.
JapanJapan Publishes Public-Comment Results On Draft Cabinet Order Amending CSCL Enforcement Order
In May 2026, Japan published the results of a public consultation on a Cabinet Order amending the Enforcement Order of its Chemical Substances Control Law (CSCL) and confirmed that the draft will be promulgated unchanged on 22 May 2026. This locks in the legal changes consulted on in March, so companies subject to Japan’s chemical control law should now treat the draft as final and review how the forthcoming Enforcement Order amendment may affect their obligations once it takes effect.
JapanJapan Publishes Consultation Results and Promulgates CSCL Ministerial Ordinance Designating Chemicals Under Enforcement Order Article 1(1)(37)
Japan has completed consultation, received no comments, and on 17 April 2026 promulgated a ministerial ordinance designating certain chemical substances under Article 1(1)(37) of the Chemical Substances Control Law (CSCL) Enforcement Order. This confirms that new CSCL designations will proceed as drafted, so manufacturers and importers in Japan should check whether any substances they handle fall under the new category before 17 June 2026, when the underlying Enforcement Order provision is scheduled to take effect.
JapanJapan Updates Joint Guidance on Operation of the Chemical Substances Control Law (CSCL)
Japan’s ministries have issued an updated joint operational notice under the Chemical Substances Control Law (CSCL), consolidated as of 1 April 2026, that codifies how key definitions, classifications and thresholds are applied in practice. The revised guidance tightens how companies determine whether substances are “new” or “existing”, when impurities and intermediates trigger notification, and which mixtures and polymers fall under CSCL, sharpening compliance decisions for Japanese chemical manufacturers and importers.
JapanJapan CSCL Authorities Update Priority Evaluation Chemical Risk Assessment Status (1 April 2026)
Japan’s CSCL authorities have issued an updated 1 April 2026 status report on 294 “priority evaluation chemical substances”, confirming 221 substances remain designated, 73 have been cancelled, and mapping each to its current screening and risk assessment stage. By showing which substances — including antimony trioxide, hexamethylenediamine, furfural, pyridine, certain alkyl glucosides and BIT — are scheduled for government risk evaluation in fiscal years 2026–2028, the report signals where future CSCL risk-management proposals are most likely, giving manufacturers time to prioritise monitoring and potential substitution.
JapanJapan METI Sets CSCL FY2025 Annual Notification Deadlines (30 June / 31 July 2026)
Japan’s Ministry of Economy, Trade and Industry has issued 2026 CSCL annual notification guidance confirming that FY2025 manufacturing and import quantities for general, priority and monitoring substances must be reported between 1 April and late June/July 2026, depending on the submission channel. Chemical manufacturers and importers should finalise CSCL inventories, SDS and classification data and ensure e-Gov or paper notifications are submitted ahead of the 30 June (paper) and 31 July 2026 (electronic/optical) cut-offs to avoid non-compliance and penalties.
JapanJapan Sets BAT-Based Conditions for Exempting CSCL Class I Impurities, Including HCB, PCBs and SCCPs
Japan’s three competent ministries have issued a CSCL notice that from 1 April 2026 sets BAT-based impurity thresholds and reporting rules for Class I Specified Chemical Substances such as HCB, PCBs and SCCPs. Manufacturers, importers and plastics recyclers must review impurity levels, file self-management limits and reduction measures where required, and ensure ongoing compliance with the new benchmarks to avoid having products treated as containing banned substances.
JapanJapan Promulgates CSCL Guidance and Test Method Amendments After Public Comment
Japan’s health, economy and environment ministries have finalised and promulgated amendments to CSCL guidance on using existing composition and property data and to the test methods and criteria for determining new and monitoring chemical substances, following a public consultation held in early 2026. These changes will influence how companies classify substances and structure testing under CSCL, so regulatory and R&D teams should factor the updated criteria into future product planning and notification strategies.
JapanJapan MHLW Consults on Ordinance Revisions Implementing PMD Act Amendments for Pharmacies and Remote OTC Sales
Japan’s Ministry of Health, Labour and Welfare has issued draft ordinances to implement 2025 amendments to the Pharmaceuticals and Medical Devices Act, overhauling pharmacy certification, GMP inspections, partial outsourcing of dispensing, remote OTC medicine handover, and some CSCL inspection documentation, with public comments due by 23 May 2026. Pharmaceutical manufacturers, distributors, pharmacies, and OTC retailers in Japan should assess how the proposed models for health promotion pharmacies, outsourced dispensing, and remote sales will affect licensing, quality systems, and digital record-keeping ahead of expected promulgation around mid-2026.
JapanJapan Designates New Priority Evaluation Chemicals Under Chemical Substances Control Law
Japan has designated nine substances, including antimony trioxide and pyridine, as priority evaluation chemicals under the Chemical Substances Control Law effective April 2026. This designation initiates government-led risk assessments that may result in future use restrictions or reclassification into more stringent regulatory categories.
JapanJapan NITE Updates CHRIP Database With Multi-Jurisdiction Chemical List Changes
Japan's NITE updated the CHRIP database on April 1, 2026, consolidating substance-level changes across major domestic and international frameworks including CSCL, ISHA, and EU CLP. Businesses must audit updated substance lists to maintain compliance with revised labeling, safety data sheet, and notification obligations across Japanese and global markets.
