Shipping Instructions

Please call us to coordinate the shipping and receiving of samples that are iced or frozen in order to minimize the chance of warming or spoilage.

  • Perishable Samples – Should be shipped overnight and on “blue ice” chill packs.
  • Frozen Samples – Should be maintained in the frozen state using dry ice.
  • Please download, complete, and include the appropriate Chain of Custody with your samples
  • Customers outside of the USA:. We have USDA import permits available for those customers wishing to send us soil or vegetation (raw, non-processed) samples from outside the United States. Having the proper permit attached to the package facilitates passage through US Customs. Please call or e-mail us for details.

TAT’s vary by commodity starting with our quickest option, Priority Rush – end of next business day, all the way out to 8 business days.
