Frequently asked questions
About this SSOC unit and the Manufacturing occupational cluster
What product safety standards apply to manufactured goods?
Enterprise Singapore and specific regulators set product safety standards. Consumer goods may be subject to Consumer Protection (Consumer Goods Safety Requirements) Regulations.
Do I need a factory registration from MOM?
Factories using machinery or employing a certain threshold of workers may require registration with the Ministry of Manpower under the Workplace Safety and Health Act.
What NEA environmental permits are needed?
Manufacturing facilities with emissions, effluents, or hazardous substances need permits from the National Environment Agency (NEA), including air emission and trade effluent licences.
Are there fire safety requirements for manufacturing premises?
SCDF fire safety requirements apply, including fire certificate requirements for certain types and sizes of industrial premises.
What is SSIC and why does it matter?
The Singapore Standard Industrial Classification (SSIC) is the national system for categorising business activities. It is mandatory at ACRA registration and is used by IRAS, MOM, and other government agencies for tax, licensing, statistical, and policy purposes.
Do I need to register with this SSIC code?
Every business entity registered with ACRA must select at least one SSIC code that best describes its principal economic activity. You can declare up to two codes — one primary and one secondary — via BizFile+.
