The U.S. Department of Agriculture has green-lighted the shipment of Hawaiian avocados to most states on the mainland.

Under a Sept. 12 ruling published in the Federal Register, the USDA’s Animal and Plant Health Inspection Service will allow Hawaiian sharwil avocados to ship to 32 states and the District of Columbia from November to March.

California and Florida, the top two biggest domestic avocado producers, are among the states where Hawaiian avocados cannot be shipped.

To ship fruit to the mainland, Hawaiian growers must submit to requirements for registration and monitoring of groves and packinghouses; an orchard trapping program; sanitation; limits on harvest periods and distribution areas; and harvesting and packing requirements.

About 180 metric tons are expected to ship annually, about half of 1% of the U.S. supply of non-hass U.S. avocado varieties and less than 1/20 of 1% of all U.S. avocados.
