Singapore SS 586 Compliance: SDS Requirements Explained
SS 586 — the Specification for Hazard Communication for Hazardous Chemicals and Dangerous Goods — sets Singapore's GHS-aligned rules for classifying, labelling, and documenting hazardous chemicals. Enforced by the Ministry of Manpower (MOM) under the Workplace Safety and Health Act, it requires a 16-section English-language SDS aligned with UN GHS Revision 7.

Enforcing AuthorityGHS Rev. 7
Current Edition AdoptedSS 586 (Specification for Hazard Communication for Hazardous Chemicals and Dangerous Goods) is Singapore's GHS implementation standard, published by the Singapore Standards Council and enforced by the Ministry of Manpower (MOM) under the Workplace Safety and Health Act. It has three parts: Part 1 covers dangerous goods classification and transport labels, Part 2 covers GHS classification and labelling of chemicals, and Part 3 covers SDS preparation. The current SS 586-2/3:2022 revision aligns Singapore with UN GHS Revision 7 and became fully mandatory on 6 February 2025 after a two-year transition period.
Who SS 586 Applies To
If you supply or manufacture a hazardous chemical for the Singapore market, you're responsible for GHS classification, labelling, and preparing a compliant SDS under SS 586 Part 3.
Bringing chemicals into Singapore? You inherit the duty to ensure the SDS meets SS 586's current GHS Revision 7 format before it reaches a customer or workplace.
Under the WSH Act, any occupier of a workplace must label hazardous substance containers correctly and keep the current SDS accessible to employees who handle them.
The 5 Core SS 586 Requirements
1. Classify
Classify every hazardous chemical against GHS Revision 7 hazard classes and categories per SS 586 Part 2.
2. Label
Labels must carry the product identifier, supplier ID, pictograms, signal words, and hazard/precautionary statements.
3. Prepare SDS
A full 16-section English-language SDS, formatted per SS 586 Part 3, must accompany every hazardous chemical supplied.
4. Store & Handle Safely
The WSH General Provisions Regulations require designated, hazard-appropriate storage for hazardous substances on-site.
5. Keep SDS Accessible
Occupiers must keep the current SDS accessible on-site to every employee who handles the hazardous substance.
Unlike Malaysia's CLASS 2013, SS 586 does not mandate a bilingual SDS — English is the required baseline. That said, many multinational suppliers still commission additional-language versions for regional workforces or export markets, and getting the English SDS technically precise under GHS Revision 7 remains the compliance-critical step.

What Non-Compliance Costs Under the WSH Act
MOM enforces SS 586 compliance under the Workplace Safety and Health Act and its General Provisions Regulations. Breaches related to managing hazardous substances — including labelling and SDS failures — carry escalating penalties for repeat offences, on top of the WSH Act's broader corporate liability.
