OREANDA-NEWS. Effective April 1, 2016, the USDA will partially relax the handling requirements prescribed under the California table grape marketing order and the table grape import regulation as it relates to the one-quarter pound minimum bunch size requirement and the import regulation for U.S. No. 1 table grade grapes packed in clamshells weighing five pounds or less. Under this revision, up to 20 percent of the weight of such clamshell containers may consist of single grape clusters weighing less than one-quarter pound but consisting of at least five berries each. It is believed that this change provides California desert grape handlers and importers with the flexibility to respond to ongoing marketing opportunities to meet consumer needs.
