Updating Labels

Chemical manufacturers, importers, distributors, or employers who become newly aware of any significant information regarding the hazards of a chemical must:

  • Revise the labels for the chemical within 6 months of becoming aware of the new information.
  • Ensure that labels on containers of hazardous chemicals shipped after that time contain the new information.
Relabeling Older Chemicals

For chemicals that have been released for shipment and are awaiting future distribution, chemical manufacturers, importers, distributors, or employers have the option not to relabel those containers; however, if they do not relabel the containers, they must either provide the updated label for each individual container with each shipment or, with the agreement of the receiving entity, transmit the labels by electronic or other technological means.

If the chemical is not currently being produced or imported, the chemical manufacturer, importer, distributor, or employer must update the label with the new information before the chemical is shipped or reintroduced into the workplace.
