Reusable Shipping Containers

Reusable Shipping Containers

As Merck continues to evolve and expand our use of the Reusable Shipping Container, Merck will be replacing the current Styrofoam Shipping Container with the Reusable Shipping Container, in phases, across the country, which will help reduce waste and negative impacts on our environment.

Important changes that you should be aware of include:

  • The Reusable Shipping Container will look different than the current Styrofoam shipping container you have been receiving.
  • As of the dates provided below, the Reusable Shipping Container will be used for ALL STANDARD small parcel shipments for ALL Merck vaccines. Please refer to the map below for the timing of the roll-out by geography.
  • Beginning March 2022, Merck plans to begin using the Reusable Shipping Container for refrigerated small parcel vaccine shipments going to central and northern states, per the map below.
  • In April 2022, Merck will begin using the Reusable Shipping Container for all frozen small parcel Merck vaccine shipments.
  • Please bear in mind that once all Merck distribution centers are using the Reusable Shipping Container, you will no longer receive Merck vaccines in the Styrofoam shipping container.

Information regarding proper handling of the new Reusable Shipping Container, along with detailed return instructions, will be included inside each of the Reusable Shipping Containers. For detailed instructions and additional information, please see the resources below.
