How long does it take to process a registration application and when can I order materials?
The amount of time required to process an application for registration depends upon the level of registration being sought. Please allow 2-3 weeks after delivery of your registration package for processing. Registration for Level 3 items may require additional time for processing. Missing, incomplete or inaccurate information and documents can extend processing time. Once your application has been reviewed and approved by NIAID, we will notify you by email with information on how to proceed with accessing your online account for the purposes of placing your order.

Is it possible to add more people to my initial institution registration who can be allowed to order materials?
Registration with BEI Resources is per the individual researcher and not the organization, department or laboratory. This means that each researcher who would like to obtain our materials will need to register with us and submit their own registration paperwork. It also means that we cannot add to or use paperwork from previously processed registration paperwork. So if you would like to have more people register with us to have access to our materials, you are free to do so, they will just need to complete their own registration packets and send it in for processing.

The  EUSLA  is not negotiable.

Can I transfer SARS-CoV-2 materials?

Material  as used in this answer, means the original material or any unmodified progeny received from BEI Resources. SARS-CoV-2 materials received under the  EUSLA  may be further distributed to other entities for legitimate purposes required to rapidly prevent, detect, prepare for, and respond to, the spread or transmission of SARS-CoV-2 and under terms no more restrictive than the Emergency Use Simple Letter Agreement (EUSLA).  To ensure compliance with this, copies of the  EUSLA  or MTAs recording all further transfers must be sent back to  contact@beiresources.org. This requirement must also ...
