Japan CSCL 2026 SVE/LVE Filing Windows Updated as G Biz ID Rollout Begins

At a Glance: Filing and Account Readiness Checklist

Japan's Chemical Substances Control Law (CSCL) authorities have updated the FY2026 filing schedules for small-volume and low-production-volume new chemical substance procedures. The update affects companies planning to manufacture or import new chemical substances in Japan in the second half of FY2026, with specific windows now available for SVE rounds 4-7 and LVE quantity confirmation rounds 4-9.

In parallel, METI is replacing the applicant code used for CSCL electronic applications with Japan's common business authentication system, G Biz ID. Overseas chemical suppliers, Japanese importers and regulatory affairs teams should complete substance status checks, route selection, submission planning and account readiness well before the applicable filing window. Companies planning a Japan filing can also review REACH24H's Japan CSCL & ISHL compliance services for related support.

Key Update 1: FY2026 SVE Filing Windows After the Third Round

The updated SVE schedule applies to the fourth to seventh FY2026 filing rounds. The available submission methods differ by round. Companies should confirm the latest METI guidance on small-volume new chemical substance procedures before filing, especially where optical disc or paper submissions are not accepted.

Key Update 2: FY2026 LVE Quantity Confirmation Windows

For LVE quantity confirmation, the fourth to ninth FY2026 windows have been updated. Confirmation notices are generally expected about one month after the application window closes. Companies should confirm the latest METI guidance on low-production-volume new chemical substance procedures before submission.

G Biz ID Will Replace Applicant Codes for CSCL Electronic Applications

METI's notice on G Biz ID transition states that applicant codes and notifier codes used for certain CSCL electronic procedures will be phased out in FY2026 and replaced by G Biz ID. For CSCL applications, only G Biz ID Prime and G Biz ID Member accounts can be used; G Biz ID Entry is not accepted for these procedures.

The transition timing differs by procedure. For SVE electronic filings, G Biz ID is scheduled to be used from the fourth FY2026 round onward. For LVE electronic filings, G Biz ID adoption is scheduled from the fifth FY2026 round onward. Submission methods and system arrangements may differ by filing round, so applicants should verify the latest METI schedule and system guidance before filing.

For companies filing in the second half of FY2026, account readiness should be treated as a practical compliance requirement. A G Biz ID Prime account requires identity review, while Member accounts are created under a Prime account. Companies should confirm whether the relevant Japanese applicant or submitting entity has an appropriate Prime or Member account before the filing window opens.

What Companies Should Do Now

• Confirm substance status and applicable law: Check whether the substance is listed on Japan's Existing and New Chemical Substances inventory and whether CSCL, ISHL or another framework applies.

• Select the correct route: If the substance is new under CSCL, determine whether standard new chemical notification, SVE, LVE or another applicable confirmation pathway is appropriate.

• Coordinate with the Japan-side applicant: Overseas suppliers should align with the Japanese manufacturer, importer or local submitting party on roles, data ownership and filing schedule.

• Prepare account access early: For electronic filing, check G Biz ID Prime or Member availability before the relevant window. Where the filing window starts in August or later, account checks should be completed in July rather than left until the filing period opens.

• Do not treat SVE/LVE as a full release from CSCL obligations: METI notes that hazardous information reporting obligations under CSCL Article 41 may still apply to small-volume and low-production-volume new chemical substances.

How REACH24H Can Support Japan CSCL Compliance

REACH24H supports companies with Japan chemical compliance, including CSCL applicability assessment, ENCS/MITI inventory search, SVE/LVE route assessment, dossier preparation, data gap review, filing schedule planning and coordination with local experts where needed. These service areas align with REACH24H's Japan CSCL & ISHL compliance service scope.

• Substance and inventory assessment: Confirm whether the substance is existing or new under CSCL and whether ISHL or another Japan framework also needs to be considered.

• SVE/LVE route assessment: Evaluate whether the planned manufacture or import scenario can follow SVE, LVE or another applicable pathway.

• Dossier and schedule planning: Support document preparation, data gap review and filing-window coordination for Japan-side submission.

• Follow-up compliance support: Support authority communication, SDS and label checks, regulatory training and post-filing obligations where relevant.
