G Biz ID (G ビズID) Types & Application Requirements

In order to improve administrative efficiency and achieve cross-domain unified identity authentication, Japan will fully implement G Biz ID (G ビズID) as a new identity recognition and business handling account.

G Biz ID (G ビズID) covers the following three forms, of which the relevant applications of the Chemical Substances Control Law require the use of 【G ビズIDプライム】 and 【G ビズIDメンバー】, which need to be applied by the importer.

【G ビズIDプライム】、【G ビズIDメンバー】、【G ビズIDエントリー】

G Biz ID (G ビズID) is planned to be gradually launched from 2026, and the specific launch time varies depending on the application type, and the subsequent official notice shall prevail. REACH24H will also continue to follow up on the latest developments and release relevant information in a timely manner.

In addition, the relevant electronic applications of the Chemical Substances Control Law(CSCL) in 2025 (including SVE, LVE, and intermediate reports) can still use the original applicant number, but REACH24H recommends applying for a new account as soon as possible to avoid subsequent application delays.

Compliance Tips from REACH24H

Important reminder for enterprises REACH24H hereby reminds all customers involved in Japanese export business, especially enterprises that apply through REACH24H, to be sure to notify the corresponding importers to complete the G Biz ID(G ビズID) application in a timely manner, so as to avoid application obstruction due to untimely account switching, which will affect the trade process.
