What is an EU SDS (Safety Data Sheet)?

Update time : 2026-09-25

In international chemical trade, safety is always the top priority. If you plan to export chemicals, mixtures, or even certain consumer products containing chemical ingredients to the European Union (EU), you will inevitably encounter one term: SDS (Safety Data Sheet). In the past, it was often referred to as msds (Material Safety Data Sheet). With the implementation of the Globally Harmonized System of Classification and Labelling of Chemicals (GHS), the EU has fully standardized it as SDS. This is not just a technical manual; it is a compliance passport for chemicals to enter the European market.

What is an EU SDS?

An EU SDS is a standardized legal document prepared in accordance with EU regulatory requirements, used to communicate the hazard characteristics and safety protection measures of chemicals (substances or mixtures). It records in detail key information such as the physical and chemical properties, toxicity, ecological impact, safe storage, emergency response, and transportation requirements of the chemicals. Its core purpose is to ensure that workplace operators, first responders, logistics personnel, and end-users can clearly understand the potential hazards of the chemicals and take necessary preventive and protective measures to safeguard personal safety and the ecological environment.

Regulations Followed by the EU SDS

The EU has very strict management of SDS, and its preparation and content must simultaneously comply with the overlapping requirements of the following core regulations:

reach regulation: This is the fundamental legal basis that dictates how an SDS should be written, its format, and its structural framework.
CLP Regulation: This stipulates the hazard classification and labeling standards for chemicals. The hazard classification, pictograms, and signal words in the SDS must be strictly consistent with the CLP Regulation.
New Implementation Standards: The latest SDS preparation standards currently enforced by the EU. These standards introduce stricter information disclosure requirements for nanomaterials, endocrine disruptors, and other specific substances.

What Content Does a Standard EU SDS Include?

According to the REACH Regulation, a standard EU SDS must contain 16 fixed sections, and the order and titles absolutely must not be arbitrarily modified or swapped:

Section	Main Content	Core Focus
1. Identification	Chemical name, Unique Formula Identifier (UFI), supplier information, emergency contact number.	Identifies "what it is" and "who to contact in an emergency".
2. Hazard Identification	Hazard classification based on CLP Regulation, GHS label elements (signal words, precautionary statements, pictograms).	Quickly reveals its core hazards (e.g., highly flammable, highly toxic).
3. Composition / Information on Ingredients	CAS number and EC number of the chemical components, and the concentration range of hazardous ingredients.	Nanoforms or specific hazardous ingredients must be disclosed here.
4. First-Aid Measures	First-aid methods and main symptoms after inhalation, skin contact, eye contact, or ingestion.	First-response guidance in case of an accident.
5. Fire-Fighting Measures	Suitable/unsuitable extinguishing media, hazardous substances produced by thermal decomposition, protection for firefighters.	Scientific firefighting methods specific to the chemical fire.
6. Accidental Release Measures	Personal protective equipment, environmental protection measures, cleanup methods for spills.	Prevents small leaks from becoming major environmental disasters.
7. Handling and Storage	Safe handling precautions, incompatible materials, ventilation requirements, safe storage conditions.	How to safely handle and store the chemical on a daily basis.
8. Exposure Controls / Personal Protection	Occupational Exposure Limits (OEL), engineering control methods, personal protective equipment (respirators, gloves, etc.).	The highest standard guide for labor protection.
9. Physical and Chemical Properties	Physical state, color, odor, pH value, melting point/boiling point, flash point, solubility, etc.	The physical and chemical parameters of the substance itself.
10. Stability and Reactivity	Reactivity, chemical stability, conditions to avoid, incompatible materials, hazardous decomposition products.	Assesses its chemical safety risks in specific environments.
11. Toxicological Information	Acute toxicity, skin irritation, serious eye damage, carcinogenicity, endocrine disruption, etc.	Data regarding hazards to human health.
12. Ecological Information	Ecotoxicity, persistence and degradability, bioaccumulative potential, mobility in soil.	Assessment of its impact on water, soil, and the environment.
13. Disposal Considerations	Waste treatment methods, disposal recommendations for contaminated packaging.	Safe and environmentally friendly regulations that must be followed upon disposal.
14. Transport Information	UN number, UN proper shipping name, transport hazard class(es), packing group, marine pollutant.	Compliance guide for land (ADR), sea (IMDG), and air (IATA) transport.
15. Regulatory Information	EU local safety, health, and environmental regulations (e.g., svhc list of substances of very high concern).	Indicates whether it is subject to specific EU laws.
16. Other Information	Revision explanations, list of abbreviations, main references.	Version iteration and traceability of sources.

New Stringent Requirements for EU SDS

The EU has always been at the global forefront of chemical safety regulation. The currently enforced (EU) 2020/878 standard has added the following highly challenging technical requirements:

Introduction of UFI (Unique Formula Identifier):
For hazardous mixtures placed on the EU market, Section 1.1 of their SDS must include a UFI code. This is to facilitate quick formula retrieval by the EU Poison Centre (PCN) in the event of a poisoning incident.
Mandatory Disclosure of "Nanoforms":
If a product contains nanoscale substances, it must be clearly indicated in multiple sections (such as Sections 1, 3, and 9), with explicit explanations of their particle size, shape, and surface characteristics.
Endocrine Disrupting Properties:
For substances known to have endocrine-disrupting properties for humans or the environment, relevant data must be detailed in Sections 2.3, 11, and 12.
Comprehensive Tightening of Classification Thresholds:
For example, the generic concentration limit for substances with an aspiration hazard has been drastically reduced from the original 10% to 1%. This means that trace ingredients that previously did not need to be disclosed in the SDS must now be compliantly listed.

Conclusion

The EU SDS is by no means a simple piece of "paper"; it is a comprehensive reflection of an enterprise's R&D, production, legal, and compliance capabilities. With the advancement of the European Green Deal and the increasingly tightened regulation of chemicals, timely and accurately updating multilingual SDSs that comply with EU standards ((EU) 2020/878) is a mandatory course for enterprises to secure their position in the European market and avoid trade risks.
