Singapore is proposing to revise two pieces of legislation on the control of five chemicals. These are proposed to become effective in March 2023.

 SG 02922 Chemical 

On February 7, 2022, the World Trade Organization (WTO) announced a notification (WTO document number 22-0921) from Singapore’s National Environment Agency (NEA) on its intention to regulate five Hazardous Substances (HS) under the nation’s Environmental Protection and Management Act 1999 (EPMA 1999) and Environment Protection and Management (Hazardous Substances) Regulations (EPM (Hazardous Substances) Regulations). 

According to the WTO notification, these five substances have potential environmental and health impacts and their inclusion is to prepare Singapore’s obligation to the Stockholm Convention, a global treaty on persistent organic pollutants (POP), and the Rotterdam Convention, a global treaty in the international trade of certain hazardous chemicals, when these five chemicals are added to the Annexes of these Conventions.

The intended control of these five HS is proposed to be published in the Government Gazette by April 2022. Economic operators (importers, manufacturers and distributors) of these five chemicals and products containing these chemicals will then be required to apply for a HS license/permit for the import, export, sale, store or use of these chemicals. 

It is important to note that Part 1 to the Second Schedule of EPMA 1999 would not provide exclusions for each of these five chemicals.

The five hazardous substances from the WTO notification and their potential applications are summarized in Table 1.
