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.
• 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.

Turn­around Times

We offer a range of Turn­around Time (TAT) options to meet your project and budgetary require­ments. TAT’s vary by test and commodity with some reporting options avail­able by end of next busi­ness day, with our most cost effec­tive options ranging from 5 to 8 busi­ness days. Please note: that end of next busi­ness day options are avail­able upon prior noti­fi­ca­tion and only for certain methods, and samples must be received at the lab before 11AM to ensure timely processing in the lab. TAT’s start from successful receipt of a complete COC upon intake.

Delivery of Certifi­cates of Analysis (COA)

COA’s will be e‑mailed as soon as work is completed. You may request a paper copy by mail. If payment must be received prior to release of COS’s unless payment terms have not been estab­lished prior to receipt of samples.
