This is intended to be a basic guideline for transport permits required for domestic (within the United States) shipment of reagents and proficiency tests. International shipment of reagents may require additional permits, and the laboratory should be contacted at or (515) 337-7266 for more information.

Shipment of certain reagents, including live agents, requires VS “Permit to Import Controlled Material or Transport Organisms or Vectors or Animal Products and By-Products”. These permits can be obtained by filling out VS Form 16-3 found on the National Center for Import and Export webpage. If you are unsure whether the reagents or proficiency tests require a permit, please contact us at or (515) 337-7266. Make sure you have the name and reagent code of the reagents available.

Some live agents require additional permits:

  • Select agents are regulated by the National Select Agent Registry. Please visit their website at for information about transfer of select agents.
  • Certain organisms, including Taylorella equigenitalis, require a VS permit that specifies the agent.
