Short answer MSDS (material safety data sheet) is the older name. SDS (safety data sheet) is the name used by the UN GHS, by EU law and, since the 2012 revision of the US Hazard Communication Standard, also in the United States. Both describe the same kind of document, but only an SDS in the current 16-section format meets today’s rules.

Where the names come from

The term material safety data sheet became widespread in the United States under the OSHA Hazard Communication Standard. The layout of the document was not fixed, so MSDSs from different suppliers often looked very different.

The Globally Harmonized System (GHS) of the United Nations introduced the name safety data sheet with 16 headings in a fixed order. OSHA aligned its standard with the GHS in 2012: for shipments from 1 June 2015, suppliers had to provide SDSs in the 16-section format instead of MSDSs.

In the EU, safety data sheets were first regulated by Commission Directive 91/155/EEC. Today the rules are in Article 31 and Annex II of REACH, in the version set by Regulation (EU) 2020/878. EU law uses only the term “safety data sheet”.

MSDS and SDS side by side

Older name

MSDS

  • Material safety data sheet
  • Name used mainly in the US before the GHS
  • Layout and order of information varied by supplier
  • No legal status in the EU as a separate document type
  • An old MSDS usually does not meet Annex II of REACH
Current name

SDS

  • Safety data sheet
  • Name used by the GHS, the EU and the US
  • 16 sections with fixed headings in a fixed order
  • In the EU: content set by Annex II to REACH (Regulation (EU) 2020/878)
  • Must be updated without delay when new information becomes available

The same document in EU languages

Each language version of REACH uses its own term. When you sell in another country, the SDS carries the name used in that language.

You received an MSDS. What now?

The title on the document matters less than what is inside. Check these points:

  • 16 sections with the headings and order set by Annex II
  • Revision date – SDSs prepared before 2023 may still follow the old Annex II format
  • Classification under CLP in section 2, with pictograms, H and P statements
  • Language – an official language of the country where you use or sell the product
  • Supplier details and an emergency telephone number in section 1

If any point is missing, ask your supplier for the current SDS. If you place the product on the market yourself, the SDS has to be brought up to date.

Have an old MSDS?

We revise it into a safety data sheet in the current format under Regulation (EU) 2020/878 and translate it into the languages you need.
