Also known as Asian pears, the Chinese sand pear variety is quite popular in many Asian countries and also has been cultivated in California and a few other states in a limited way since the 1980s.
The USDA's "initial regulatory flexibility analysis" ("regulatory" and "flexibility" don't go together, do you agree?) on Chinese sand pear imports reveals the fruit is no wilting shrinking violet in terms of volume. The USDA observes:
China expects to export 24,000 metric tons of Chinese sand pear to the United States, but we do not know the quantity or value of Chinese sand pear imported from other countries. Nor do we know the substitutability of Chinese sand pear for other types of pears produced domestically.
