Every country has its own regulations regarding expiration dates on SDS sheets.
In the USA, OSHA SDS sheets have no specific requirements concerning expiration dates.
OSHA does require that the SDS must accompany the first shipment of chemicals. Any revised or updated SDS should be provided with the new preparation date and must be issued within three months if any of the following conditions are met :
- There has been a significant change to the chemical makeup or composition
- A health or physical hazard that is different from previously stated is discovered
- The product has been listed as carcinogenic
In Canada, the WHMIS SDS sheets expire every 3 years. The SDS sheet must be updated to provide any new information that has become available since the date it was first prepared. This may include a change in the formulation or information that has demonstrated a hazard that was not previously stated. Under the WHMIS , any SDS must be accurate at the time of sale or importation of the said hazardous product.
In the European Union, under the old CLP regulations SDS sheets, like an SDS in the USA, do not have a specific expiration date, however if any information has been added, deleted, or revised, the said change must clearly be depicted on the revised sheet.
In all cases, the SDS sheet must list the date of preparation or data of revision on the form .
