SDS vs MSDS — what changed and what to do
MSDS (Material Safety Data Sheet) was the format used in the US before 2012. MSDSs had a variable number of sections (typically 8–16), no standardized order, and inconsistent content. A fire extinguisher MSDS might look completely different from a cleaning solvent MSDS.
In 2012, OSHA updated HazCom to align with the Globally Harmonised System (GHS). The updated format — now called SDS — has exactly 16 sections in a fixed order. Every SDS looks the same structurally, regardless of the manufacturer or country of origin. This makes it much easier for emergency responders and workers to find information quickly.
OSHA's deadline for full GHS compliance was June 1, 2016. Any MSDS in old format should have been replaced with a GHS SDS by that date. If you have old MSDSs, they are not compliant and should be replaced. If you are preparing a new document, it must be in the 16-section GHS SDS format.
SDSDraft generates a DRAFT safety data sheet from the information you enter. You are solely responsible for verifying the hazard classification and all content with a qualified person before use or distribution. SDSDraft is software, not professional safety, legal, or toxicological advice.

Converting old MSDS documents
- Identify any MSDS documents that predate the 2012 GHS update.
- Check whether the product is still in use and needs a current SDS.
- Contact the manufacturer or importer for an updated GHS SDS.
- If you are the manufacturer: use the old MSDS data as a starting point, but reclassify under GHS criteria and reformat as a 16-section SDS.
- Verify the GHS classification against current ingredient SDSs — the old MSDS hazard assessment may be outdated.
Questions
Are MSDSs still legally acceptable?
No. OSHA requires GHS-format SDSs. An MSDS in pre-2012 format does not meet HazCom requirements. Replace any MSDSs with GHS SDSs.
Can I just rename my MSDS to SDS?
No. The 16-section GHS structure must be followed. A renamed MSDS without restructuring and reclassification under GHS criteria is not a compliant SDS.
I received a product with an MSDS. What should I do?
Contact the supplier and request a GHS-compliant SDS. If they cannot provide one, consider sourcing from a supplier who maintains GHS compliance. As an importer, you can also prepare your own SDS based on GHS classification.
