Important requirements manufacturers, importers and distributors must meet are:
Prepare one SDS that applies to all similar mixtures where complex mixtures have similar hazards and contents (i.e. the chemical ingredients are essentially the same, but the specific composition varies from mixture to mixture).
Ensure that the SDS information recorded accurately reflects the scientific evidence used in making the hazard classification.
Add new information to the SDS within three months after becoming aware of any significant new information regarding the hazards of a chemical, or ways to protect against the hazards.
If the chemical is not currently being produced or imported, add any new information to the material SDS before the chemical is introduced into the workplace again.
Provide an appropriate SDS with the initial shipment, with the first shipment after a SDS is updated, and as requested by the employer or distributor.
Retail distributors selling hazardous chemicals to employers having a commercial account must:
provide a SDS to such employers upon request, and
post a sign or otherwise inform them that a SDS is available.
