FAQ

1.Relationship with the gGHS mixture classification systemh published by METI in Japan

Q1-1 Let me know the relationship and changes between the METIfs GHS mixture classification system and NITE-Gmiccs.

A1-1 NITE-Gmiccs basically contains the same information and functions as the METIfs GHS mixture classification system, but the main changes are as follows.

Change from software installed system to web system.
NITE-Gmiccs can be used via Internet from any terminal at any time without the need to install software.

Change the Excel format for import / export.
You can manage multiple chemical substances using the Excel format (CSV).

User does not need to update data.
NITE will carry out the registration of the latest GHS classification results by the Japanese government to NITE-Gmiccs and the system update.

Q1-2 Is there any difference in the registered substance information between the METIfs GHS mixture classification system and NITE-Gmiccs?

A1-2 Basically, substance information based on the GHS classification results by the Japanese government are registered in NITE-Gmiccs, but please note that there are the following changes.
Different substance ID(Ex. substance ID for formaldehyde ... 00000000045 -> m-nite-50-00-0)
In NITE-Gmiccs, the GHS Classification Results by the Japanese Government (NITE edited version) are registered. (NITE edited version(Currently, only Japanese site is available)j
Water (CAS RN: 7732-18-5) is not classified by the Japanese government, but the classification result is registered in NITE-Gmiccs for convenience.

Q1-3 Is it possible to transfer or use the data had being used in METI's GHS Mixture Classification System to NITE-Gmiccs?

A1-3 The Excel file (TSV format) output from the METI's GHS mixture classification system cannot be used on NITE-Gmiccs. Please enter the data in the new Excel format for NITE-Gmiccsbefore using.

Q1-4 Is it possible to import own company data and save it in NITE-Gmiccs in the same way as the METI's GHS mixture classification system?

A1-4 You can import your company data, but you cannot save the data in NITE-Gmiccs. Please enter data in the import file for NITE-Gmiccs (Excel file (CSV format)) and import it. When you want to save the data, be sure to export the data and save it as an Excel file (CSV format) on your terminal. Also, please note that NITE-Gmiccs will timeout after 2 hours of inactivity.

Q1-5 If the GHS Classification Results by the Japanese Government are updated, do I have to upload (import) the updated data by myself in the same way as the METI's GHS mixture classification system?

A1-5 Users do not need to upload (import) updated data. When the GHS Classification Results by the Japanese Government are updated, NITE organizes the information and updates registration information in NITE-Gmiccs. (Basically, NITE plans to update it once a year when the GHS Classification Results by the Japanese Government are updated.)

2.How to use NITE-Gmiccs

Q2-1 Is the input data, classification result, and label output result saved in NITE-Gmiccs?

A2-1 Your data and results are not saved in NITE-Gmiccs. All imported data by user will be deleted when the web browser is closed or NITE-Gmiccs times out after a certain period of time.

Q2-2 We want to use our company data for classification, how can we create the data?

A2-2 You can use your company data. Enter the data in the import file for NITE-Gmiccs (Excel file (CSV format)) and import it.

Q2-3 I want to install it on my PC and use it offline instead of the web version. Is it possible?

A2-3 NITE-Gmiccs cannot be used offline. If you want to perform mixture classification offline, please use the METIfs GHS mixture classification system. (METI: GHS mixture classification systemj

Q2-4 Can I temporarily save data in NITE-Gmiccs while entering?

A2-4 You cannot temporarily save data in NITE-Gmiccs. Be sure to export the data and save it as an Excel file (CSV format) on your PC. Also, please note that NITE-Gmiccs will timeout after 2 hours of inactivity.

Q2-5 Is it possible to share data with multiple users in the office?

A2-5 Data cannot be shared in NITE-Gmiccs, but data can be shared using the export file output from NITE-Gmiccs. If you want to share data, please use the import file or export file (Excel file (CSV format)) created by the user.

3.The function of NITE-Gmiccs

Q3-1 What kind of data is registered in NITE-Gmiccs?

A3-1 In NITE-Gmiccs, the GHS Classification Results by the Japanese Government (NITE edited version) are registered. (For details on NITE edited version(Currently, only Japanese site is available)j
Also, Water (CAS RN: 7732-18-5) is not classified by the Japanese government, but the classification result is registered in NITE-Gmiccs for convenience.

Q3-2 Can I change the classification results registered in NITE-Gmiccs?

A3-2 The GHS Classification Results by the Japanese Government (NITE edited version) registered in NITE-Gmiccs cannot be changed by user. When the GHS Classification Results by the Japanese Government are updated, NITE organizes the information and updates registration information in NITE-Gmiccs. If you want to edit data based on the data published on the NITE website, please copy and paste it into NITE-Gmiccs or create data by yourself.

Q3-3 Is it possible to modify the classification result after automatic classification with NITE-Gmiccs?

A3-3 It is possible to modify the result automatically classified by NITE-Gmiccs. Please modify data under the responsibility of user.

4.GHS classification logic of mixture

Q4-1 If I classify a mixture with NITE-Gmiccs, isn't it necessary to do GHS classification by myself?

A4-1 Since NITE-Gmiccs targets the GHS classification of chemicals (mixtures), it is necessary to prepare the data on a single substance (ingredient). NITE-Gmiccs contains the GHS classification results of about 3,000 single chemical substances as default data, but if there is no data, user must prepare it.
Also, this system does not consider the Bridging Principle of classification or the like, it performs classification only that can be done by calculation. Therefore, in some cases, not all classifications are done.The Bridging Principle icludes the following classification methods: When diluted, the same classification as the substance before dilution, Equivalent classification for the same production batch, If a highly hazardous mixture (Category 1) is concentrated, it is classified as equivalent classification, interpolation within one hazard category. If the Bridging Principle can be applied, classification should be performed using the Bridging Principle.

Q4-2 It seems that the results of the physical hazards classified by NITE-Gmiccs is incorrect. why?

A4-2 In this system, only the classification that can be calculated is performed, so some physical hazards that cannot be calculated are not classified. As for physical hazards (flammable gases, oxidizing gases, flammable liquids), although it is possible to classify it based on the information entered in NITE-Gmiccs (flash point, Initial boiling point, the equivalence factor (Ki) to inert gas/nitrogen, etc.), as for other hazards, the data must be manually entered by user because it is necessary to judge the classification based on the results of tests. On the other hand, if the GHS classification of the physical hazard of a mixture can be inferred from "Hazard class" and "Packing Group" associated with the "UN number" used in the UNRTDG, the GHS classification is automatically done. For details, please refer to Classification Logic.

Q4-3 Does the GHS classification rule "JIS" of NITE-Gmiccs follow the latest JIS?

A4-3 Classification is based on the latest JIS Z 7252 (Classification of chemicals based on "Globally Harmonized System of Classification and Labelling of Chemicals (GHS)") and JIS Z 7253 (Hazard Communication of Chemicals Based on GHS - Labelling and Safety Data Sheet(SDS) (2019 edition) (As of April 2021). For details, please refer to Classification Logic. Please refer to here for the difference between JIS rules and UN rules.

Q4-4 What edition of the UN GHS is the GHS classification rule gUNh of NITE-Gmiccs in accordance with?

A4-4 It is in accordance with the UN GHS sixth revised edition (As of April 2021). For details, please refer to Classification Logic. Please refer to here for the difference between JIS rules and UN rules.
