Little Pro on 2015-12-31

Taiwan Occupational Safety and Health Act (previously Labor Safety and Health Act) was promulgated by the Ministry of Labor(MoL) on 3 July 2013 and takes effect on 3 July 2014. New provisions related to new substance registrations come into force from 1 Jan 2015.

On 13 April 2015, the Ministry of Labor has published the first list of 580 priority management chemical substances for public consultations. Among the 580 substances, 123 substances are CMR category 1 substances. To understand what this means to your business, you have to understand how chemicals are regulated by OSHA first.

Main Requirements of Taiwan OSHA

Under OSHA, manufacturers or importers shall not manufacture or import new substances prior to submitting hazard information and obtaining registration approval. In addition to that, OSHA prohibits the handling or use of certain controlled chemicals in workplace and requires suppliers and employers to provide labels and safety data sheets..

The table below summarizes how different types of chemicals are regulated under Taiwan OSHA.

New Substance
  • New substance notification (Article 13) ;
  • Who: domestic manufacturer, importer.
Controlled Chemicals
  • Prohibition from handling or use (Article 14);
  • Who: manufacturer, importer, supplier, employer.
Priority Management Chemicals
  • Reporting handling information (Article 14).
  • Who: manufacturer, importer, supplier, employer.
All Hazardous Chemicals with Physical and Health Hazards(*)
  • Classification, labelling and SDSs according to GHS (Article 10);

New Substance Notification under Taiwan OSHA

Both OSHA and Toxic Chemical Substance Control Act (TCSCA) require a new substance to be notified prior to its production and importation. While the type of new substance notification is the same and required data is similar, there are many differences between notifying a new substance under OSHA and notifying a new substance under TCSCA. The table below summarizes the main differences between OSHA and TCSCA when it comes to new substance notification.

Registration Target
  • OSHA: New substances;
  • TCSCA: New substances and existing substances;
Type of Notification
  • OSHA: Standard registration, simplified registration and small quantity Registration;
  • TCSCA: Same as OSHA with one additional type: Phase I registration of existing substances.
Standard Registration - Hazard Data
  • OSHA: Same as TCSCA's requirement except no need of eco-toxicology data;
  • TCSCA: Extra requirement on eco-toxicology data and PBT/vPvB assessment;
Chemical Risk Assessment
  • OSHA: Required for >=1t/y CMR substances and >=10t/y regular new substances;
  • TCSCA: Required for >=1t/y CMR substances and >=1000t/y regular substances.
Transitional Measures
  • OSHA: New substances manufactured or imported into Taiwan prior to 11 Dec 2014 need to go through small quantity registration process; certificate valid for 1 year only.
  • TCSCA: Substances M/I prior to 11 Dec 2014 are eligible for inclusion in existing substance inventory without notification.
Registration Platform

The Ministry of Labor is discussing with EPA to form a single window for companies to submit new substance registrations in Taiwan. However, data and dossiers submitted need to meet the requirements of both Ministries.
