Taiwan Chemical Inventory Information

The Taiwan Chemical Substance Inventory (TCSI) contains approximately 108,000 substances, divided into existing and new substances. It was established under the framework of the Toxic and Chemical Substances of Concern Control Act (TCSCA) and the Occupational Safety and Health Act (OSHA). The cut-off date for inclusion of substances in the inventory was 2014, based on substances that were commercially available in Taiwan before that year. Listed substances have simplified requirements for compliance, such as notification of uses, hazard labelling, and SDS requirements. Non-listed substances require pre-market registration and approval, which includes substance identification, hazard and toxicity data, risk assessment, and a rigorous risk assessment process.  

The inventory is part of a robust framework that emphasizes risk-based management and alignment with global standards. 

• Scope: Lists existing and new chemical substances manufactured or imported into Taiwan, with clear categorization for industrial and consumer uses. 

• Status: Fully operational and regularly updated. 

• Existing Substances: Existing chemical substances manufactured or imported in quantities of 0.1 tonnes per year must be pre-registered before manufacture or importation into Taiwan. Streamlined compliance processes, focusing on labelling and SDS requirements, and notification of use, with additional requirements in specific cases. 

• New Substances: Substances not listed in the TCSI are considered as new and must be registered before their manufacture or importation. with registrations ranging from standard, simplified, and low volume depending on the substance's form and risk. Require pre-market registration, including detailed hazard and exposure data. 

• Regulatory Approach: The TCSI promotes safe chemical management while enabling innovation by enforcing stringent requirements for new chemicals. 

In Taiwan, the Taiwan Chemical Substance Inventory (TCSI) includes both public and confidential sections. Companies may request confidentiality for specific data, such as exact chemical identities, when submitting registration applications. Regulatory authorities regularly review these claims to maintain a balance between transparency and the protection of sensitive business information.
