7 CFR 984.13: To handle.

To handle means to receive, pack, sell, consign, transport, or ship (except as a common or contract carrier of walnuts owned by another person), or in any other way to put walnuts, inshell or shelled, into the current of commerce either within the area of production or from such area to any point outside thereof, or for a manufacturer or retailer within the area of production to purchase directly from a grower. However, sales and deliveries by a grower to handlers, hullers, or other processors within the area of production shall not, in itself, be considered as handling by a grower. The term “to handle” shall not include sales and deliveries within the area of production between handlers.
