What this means is that all Chilean seedless grape varieties, arriving in the U.S. on April 10th or later, must meet the same requirements as that of the marketing order. The minimum grade is U.S. No. 1, including the requirements of meeting the minimum soluble solids, for the respective variety.

Grape varieties, covered under the MO, must be inspected by the USDA upon arrival into the U.S. and those grapes that fail to meet the requirements of U.S. No. 1 may not be imported into the U.S. They are usually either dumped, or shipped to Canada, depending on the severity of defects.

Remember, this applies only to grapes arriving in the U.S. on or after April 10th. It is possible you may be receiving grapes that were imported weeks earlier and held in storage, before the April 10th date, that were never inspected.
