DETROIT (AP) — Michigan farmers and lawmakers want the federal government to impose a hefty tariff on dried tart cherries imported from Turkey, arguing that a subsidy on the fruit is impeding American farmers’ ability to compete.

Cherry companies from Michigan and Utah on Tuesday asked the U.S. Commerce Department and International Trade Commission for a nearly 650% in tariff hikes on tart cherries imported from Turkey. The petition request would increase the price of $1 worth of cherries to $6.48.

U.S. Sen. Gary Peters from Michigan also backed the petition.

“Michigan produces more than 70% of the nation’s tart cherries,” Peters said. “Unfortunately, Michigan cherry farmers have been forced to compete with heavily government subsidized cherry products from Turkey.”ì

Michigan-based cherry processors Traverse City’s Shoreline Fruit, Cherry Central Cooperative, Frankfort’s Smeltzer Orchard Co., and Graceland Fruit along with Utah-based Payson Fruit Growers Co-op make up the Dried Tart Cherry Trade Committee that filed the petition, The Detroit News reported.

The companies allege Turkey is bringing dried tart cherries into the U.S. at a margin of up to 648% below fair value because of Turkish government subsidies– including grants, loans, investment incentives, tax credits and land provisions.

The ITC has been investigating whether Turkish subsidies have been hindering American farmers’ from competing.
