Taiwan Chemical Substance Inventory (TCSI) Update

Contact us

September 25, 2015

Following the conclusion of the Existing Chemical Substance Nomination (ECN) on December 31, 2010, the Supplementary Existing Chemical Substance Nomination (SECN) on August 31, 2012, and the Second Supplementary Existing Substance Nomination (SSECN) on July 31, 2014, the Ministry of Labor published the Taiwan Chemical Substance Inventory (TCSI) on December 31, 2014, with approximately 93,000 substances.

On September 8, 2015, the TCSI was updated via OSHA Order No. 10402028452. After the amendment, the TCSI is made up of approximately 100,000 chemical substances, with approximately 76,400 substances with CAS numbers, 19,000 substances with serial numbers beginning with ‘N-‘, 1,000 substances with serial numbers beginning with ‘P-‘, 600 substances with serial numbers beginning with “C” and 3,000 substances with serial numbers beginning with “E”. Substances with N-numbers and E-numbers are substances without CAS numbers, while substances with P-numbers and C-numbers are those with protected data.

In this amendment, the inventory has been harmonized from substances registered via both the Taiwan Ministry of Labor (MOL) and the Environmental Protection Administration (EPA), under the Occupational Safety and Health Act and Toxic Chemical Substances Control Act.

This inventory serves as an important reference for the development of chemical management in Taiwan. The inventory is searchable by CAS number, serial number and Chinese or English chemical names through the website of Chemical Registration Management (CSNN), Occupational Safety and Health Administration, Ministry of Labor.
