NOTE:
* A blank or "-" in a cell of classification denotes that the classification of the hazard class was not conducted.
* Hazard_statement_and/or_Precautionary_statement will show when hovering the mouse over a code of Hazard_statement_and/or_Precautionary_statement.
Hazard_statement_and/or_Precautionary_statement are also provided in the Excel file.
* Classification was conducted by relevant Japanese Ministries in accordance with GHS Classification Guidance for the Japanese Government,
and is intended to provide a reference for preparing GHS labelling and SDS for users.
* This is a provisional English translation of classification results and is subject to revision without notice.
* The responsibility for any resulting GHS labelling and SDS referenced from this site is with users.
* Codes assigned to each of the hazard statements and codes for each of the precautionary statement are
based on the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) in United Nations.
