I. Background and Overview of Update Content

Historical Background and Importance of the Chemical Substances Control Law

Japan's "Chemical Substances Control Law" (abbreviated as "CSCL") is an important regulation enacted by the Japanese government to control the production and distribution of chemical substances, ensuring environmental and public health safety. Since its promulgation, the review and management of chemical substances have been a key focus of Japanese government oversight. On June 26, 2024, the Ministry of Economy, Trade and Industry of Japan issued a notice regarding updates to the customs clearance procedures under the CSCL. The new regulations will take effect from July 1, 2024, while the previous notice will be abolished as of June 30, 2024.

Main Contents of This Update

The content of this update mainly includes three aspects:

• Rationalization of Customs Clearance Procedures for Substances (for Experimental Research Purposes): Simplified the customs clearance process for new substances used for experimental research purposes.
• Unification of Some Terms: Unified and standardized the terms in the regulations.
• Update of Declaration Template: Updated the declaration template used for customs clearance to make it more in line with actual operation requirements.

II. Specific Requirements for Experimental Research Purposes

Definition of Experimental Research Purposes

According to the Chemical Substances Control Law, if a new substance is used for compliant experimental research purposes, it may be exempt from new substance notification and can be cleared through the submission of a self-declaration. Based on the "General Principles for the Application of the Chemical Substances Control Law," REACH24H has provided the following interpretation of the exemptible "experimental research purposes" and "reagent purposes":

a. Experimental Research Purposes

• Scope: Includes new substances for experiments, research, development, and inspections in all public or private institutions (such as schools, research institutes, and inspection agencies), as well as samples used for the practical application of research results in industry, and these samples are not for sale.
• Requirements: These new substances shall all be used for experimental research activities and shall not flow into the market for commercial sales.

b. Reagent Purposes

• Definition: Chemical substances used for substance detection, quantification, substance synthesis experiments, or determination of physical properties by chemical methods.
• Judgment principle: Judgment shall be made based on the packaging and manufacturing form of the substance. Industrial drugs and raw materials do not fall within the category of reagents.

Requirements for Self - Declaration

For new substances that meet the experimental research purpose, enterprises can go through customs clearance by means of self - declaration. The self - declaration shall include the following contents:

• Detailed description of the substance: Including chemical name, CAS number, use, etc.
• Description of the place of use and purpose: Specify in detail which institution the substance is used for and what purpose.
• Usage amount and time limit: The expected amount and time of use.
