Q1: What is a MITI number?
A1: Any substance that is not on the Chemical Substances Control Law (CSCL) Inventory is classified as a "new chemical", which means that it does not have a MITI number. There are approximately 20,000 existing chemical substances that have MITI numbers in the inventory at this time.
 
Q2: How do I research a MITI number?
A2: In order to determine if the substance you are working with is a new chemical, please use CHRIP to look for the MITI number for that chemical. There are several ways to use CHRIP.
When you cannot identify a MITI number for a chemical by its CAS number using CHRIP, please look for the MITI number by chemical name - you may be able to find the corresponding MITI number.
NITE does not provide any service to search for the MITI number by its CAS number. We helpto confirm the corresponding and interpretation of cabinet order name    
 
There are several points that should be considered when looking for a MITI number by chemical name:

• The names of polymers may be derived from monomer names and the methods of polymerization.
• Hydrocarbons might have generic chemical names. Search by names such as “Alkane”, “Alkyl”, “Alkylene”, “Alkenyl” etc.
• Use the functional group name with a space (e.g., nitro, amino, azo, phenyl).
• Dyes might be named using the “Color Index Generic Name”.

 
Q3: What is the definition of an impure compound?
A3:When the content of an impure compound is less than one percent by weight, the compound is not regarded as a new chemical substance. An “impurity” refers to unintended substances such as unreacted raw materials, reaction catalysts, chemical indicators, and by-products generated by reactions that are not intended.
 
Q4: What do “・”and “,“mean in the CSCL inventory?
A4: In the column for name in the list of existing chemical substances, “・”and other marks possess the following meaning:
(i) “・”generally stands for ”and”.
(ii) ”,”generally stands for “or”, except when it indicates the end of a paragraph.
(iii) When the number of substituents is not shown, the number is one in principle.
 
Q5 Who must submit a new chemical notification under CSCL?
A5: The manufacturer and the either importer or foreign exporter, but not both must submit it. In the case of exporting new chemicals to Japan, the Japanese importer needs to do the up-front notification for new chemicals under CSCL. Exporter can replace the importer and do an up-front notification. In this case, the importer is not required to do an up-front notification.
Note that exporter can submit only regular notification. Please check the types of notification under CSCL.
 
Q6: What information must be submitted about new chemical substances?
A6: Please check the data requirement under CSCL.
