See additional Regulated Chemicals Information.


CHEMLIST® (Regulated Chemicals Listing), produced by CAS, is an electronic collection of thousands of chemical substances that are regulated in key markets across the globe. CHEMLIST contains more than 348,000 substances.

How do we count

The CHEMLIST database began with national chemical inventories such as Toxic Substances Control Act (TSCA), European Inventory of Existing Commercial Chemical Substances (EINECS), Existing and New Chemical Substances (ENCS), and Inventory of Existing Chemical Substances in China (IECSC). Today, it includes international lists for high production volume (HPV) chemicals, priority chemicals, dangerous chemicals with transportation restrictions, as well as pollutant release inventories.

CHEMLIST offers the convenience of identifying--in one place--the regulatory requirements for a specific substance from many of the world's most significant regulated substances lists.


Inventories and lists from 1980 to the present

Update frequency

More than 50 new substances or additions to existing substances are added to the database each week.
