The Japan Industrial Standard (JIS) Z 7252:2014 Classification of Chemicals based on Globally Harmonized System of Classification and Labeling of Chemicals (GHS) was published on March 25, 2014. It brings the previous edition, Z 7252:2009 into line with the 4th revised edition of the UN Purple Book by adding physical hazards and hazardous to the ozone layer endpoints.
JIS Z 7252:2014 adopts all hazardous classes and categories of physical hazards as well as hazardous to the ozone layer category 1 from the Purple Book. As for the health hazards section and hazardous to the aquatic environment endpoints, no major changes were made from the 2009 edition to the 2014 edition. It must be noted, though, that Japan had previously chosen the building block approach and had not implemented the following hazard categories: acute toxicity category 5, skin irritation category 3, and aspiration toxicity category 2. This has not changed. In addition, attention should be paid to the cut-off/concentration limit values Japan adopted. Lower values are chosen for certain endpoints in classifying hazardous mixtures and determining Safety Data Sheet (SDS) disclosure requirements. For example, when containing a carcinogenicity category 2 ingredient at concentration of greater than or equal to 1%, the mixture itself shall be classified as carcinogenicity category 2. When the concentration of the same ingredient in a mixture is less than 1 % but greater than or equal to 0.1 %, the product may not be classified as a carcinogen; however, the identity of the component must be disclosed on the SDS.
Japan’s Industrial Standard for Safety Data Sheet (SDS) and Labeling was published separately in 2012 as JIS Z 7253, and the 4th revised edition of the Purple Book has already been implemented in that standard. Classification of chemicals as well as preparation of labels and SDSs for hazardous chemicals in Japan must be done in accordance with Z 7252:2014 and Z 7253:2012, respectively, by January 1, 2017.
