Whether Pre-marketing New Chemical Notification is Necessary



Required Actions for New Substance Chemicals under CSCL

Procedure type

Notification type



Standard notification

Different testing data depends on biodegradability of the substance.


Low volume confirmation (New substances ≤ 10t/y)

The substance is confirmed as non-biodegradable, non-bio-accumulative and the total volume of the substance manufactured/imported in Japan is ≤ 10 t/y.


Small amount confirmation (New substances ≤ 1t/y)

No testing data is required, the total volume of the manufactured/imported substance in Japan is ≤ 1t/y.



M/I’s may apply for confirmation instead of the full notification.


Export only


Polymer of low concern

Requirements for Chemicals other than New Chemicals

Chemical type


Existing chemicals (Japan ENCS)

General chemicals

Annual reporting of the volume of M/I uses.

Exempt chemicals

No requirements

Priority assessment chemicals (PACs)

Annual reporting of the volume of M/I uses if the volume is > 1t/y.

Monitoring chemicals

Annual reporting of the quanity and the use is required after M/I, if the volume is > 1kg/y.

Class 2 specified chemicals

Notification of planned quantity of manufacture or import should be submitted a month before manufacture or import of the chemical.

How to Check the Status of a Chemical Substance

J-Check: provides information regarding CSCL, such as the lists of CSCL, chemical safety information obtained in the existing chemicals survey programme and the Japan Challenge Programme in cooperation with eChemPortal by OECD.

NITE CHRIP: comprehensive information on risk assessments, laws and regulations of chemical substances that can be searched by entering a number or name, can also provide a list for each category.

All above lists can also be searched via CIRS's ChemRadar.
