Shipping Instructions for Clients

Samples are most reliably shipped and tracked via FedEx. Our experience has shown that samples shipped by North American clients are usually received within 24 hours.

In order to facilitate customs handling, samples should be labelled as geological rock samples for scientific examination (not "soil" or "mud") and assessed at a value of $5.

Please indicate your preferences for cover slip and sieve size in your order; otherwise, we can recommend a size suitable to your needs. Cover slips are 22x22mm or 22x40mm. Available sieve sizes are 5μm, 10μm, 15μm, 20μm, 30μm, 35μm, 44μm, 100μm, 160μm, 180μm, and 250μm.

Please indicate how you would like your samples labelled and the unit of depth given in your order.
