Orders for Delivery

It is highly recommended that you arrange to pick up your order. However, we understand that this may not always be reasonable. In these cases, please be aware that seed are delicate and need to be handled with care and in a timely manner to avoid problems that may arise. The hatchery is not responsible for damage during shipping once you have accepted the shipment at your site. Please follow the procedures outlined in this document when handling your shipment. Shipments should be accepted by someone that is familiar with the procedures, and accepted only if the shipment is in good shape. Failure to follow the protocols outlined by the hatchery may result in the loss of oysters within the shipment and is the responsibility of the grower, not the hatchery.

Once notice is given that your seed order is ready, you will be given a total balance due (less your deposit) that does not include shipping costs. All orders MUST BE PAID IN FULL before product will be released/shipped. Once full payment is received, a hatchery staff member will assist with scheduling a shipment of your order via FedEx or another shipper selected by the customer. Upon notice, shipping must be scheduled within 7 business days with delivery date within 10 business days.. Failure to schedule/receive shipment within this time frame could delay your order. Future product availability is not guaranteed. We do not ship on Fridays or weekends.  There are two shipping options; 1. You pay a separate invoice for shipping after FedEx calculates costs billed by HPL monthly, or 2.  You obtain your own FedEx account number and are billed directly from FedEx.  All orders MUST BE PAID IN FULL before product will be released.  Orders containing 200,000 or more seed may have to be shipped in multiple shipments over a given timespan.
