The Act also strengthens the management of Class 4 toxic chemical substances. Enterprises are required to declare relevant toxicological information and obtain approval from competent authorities for Class 4 toxic chemical substances prior to handling. The provisions pertaining to chemical registrations have come into force on 11 Dec 2014. CIRS summaries major points of the rules.

The table below shows the definitions of Class 1, 2, 3 & 4 toxic chemical substances and how they are regulated under TCSCA.

About us and contact

We have provided one-stop chemical notification and GHS services for many companies doing business in/with Asia (for example, China, Japan, Korea, Taiwan, Malaysia, and Philippine). We help them find out how their chemicals are regulated in those countries or regions and offer free initial consultations about how to comply. If notification is required, we help them submit chemical registrations (sometimes via our local partners). We also prepare or translate GHS compliant SDS and label in accordance with their national chemical legislation at affordable prices.
