Make sure the sample is in good condition and dry. Wrap the sample in burlap to protect it during shipping and storage.

Pack the sample and the identification tag into a durable container for shipping.

Insulating Shipments

Insulate the shipping package if there is any chance of freezing. Freezing of samples during shipping happens more frequently than expected.

We suggest using Rubbermaid Totes insulated with several layers of burlap sacking or with several layers of cardboard.



As styrofoam is difficult to recycle, we ask that clients avoid using it to ship.

Cutting post harvest samples.
A note on scooping out the potato eyes, cutting the ends off the samples or halving the potatoes for Post Harvest testing. Although this method will save on shipping weight, these samples are much more susceptible to decomposition and rot. We ask that clients ship small potatoes that are undamaged for best Post Harvest testing results.
