Japan Seeks Testing Data from Industry to Classify Substances

Japan is ramping up efforts to gather industry data to classify chemicals according to Japan GHS standards and publish recommended classifications.

Announced on NITE's website in mid-April 2023, the Japanese government started this year's "Public-Private Partnership GHS Classification Information Collection Project".

Via NITE’s platform, the private sector businesses are asked to submit test reports they own and academic papers (in books/journals/websites) reviewed by a third party for:

  • substances with official GHS classification results over the years (access the substances here);

  • substances planned for GHS classification in 2023 (access the substances here); and

  • substances without highly credible GHS classifications internationally.

SDSs can be submitted alongside as reference materials. The SDSs are for official internal use only and will not be made public.

Suppose a company wishes to submit data for "substances planned for GHS classification in 2023". In that case, it needs to email the authority to express its intention to submit before June 30 of this year. Otherwise, the data submitted later may not be used for this year's official classification.

If the data provided by the company is adopted, the company name will be made public, but the company can apply to remain anonymous. In addition, this project only accepts pure substances information and not mixtures.

Background

The Ministry of Health, Labor and Welfare (MHLW), the Ministry of Economy, Trade and Industry (METI), and the Ministry of the Environment (MoE) have been classifying chemicals according to Japan GHS and publishing recommended classifications since 2006. So far, more than 3,000 substances have been classified, of which only some are mandatorily subject to GHS-related obligations in Japan. All GHS-classified substances are searchable via the GHS Mixture Classification and SDS/Label Preparation Creation System (NITE-Gmiccs).

As planned, 50 to 100 chemical substances will be classified per year. However, the official progress in the collection of chemical hazard information has been slow and the number of chemical substances that cannot be classified due to insufficient data is increasing. To this end, the project is launched in 2022 (CL news) by the authorities joining forces with the National Institute of Occupational Safety and Health (JNIOSH) and NITE to regularly seek the industry's input for helping classify chemical substances.
