splash and dash
n.— «But the law did not anticipate “splash and dash”—a loophole in the system. This practice involves bringing a tanker of biodiesel made elsewhere, usually Indonesia or Malaysia, to the United States, adding just a “splash” of U.S.-made petroleum diesel, then shipping the “blend” to Europe for sale. Adding just 0.1 percent petroleum diesel to a load of biodiesel while at a U.S. dock is enough to qualify for the credit.» —“Loophole in Biodiesel Tax Credit Prompts Outcry” by Emily Harris NPR Sept. 2, 2007.
