"Slave-Labor Loophole Closed by U.S. Senate After 8 Decades", 11 Feb. 2016

For 85 years, the U.S. government has turned a blind eye to companies that import goods derived from slavery -- so long as domestic production couldn’t meet demand for those goods. That’s about to change. The U.S. Senate on Thursday voted to close a loophole in the Tariff Act of 1930, which bars goods made by convict, forced or indentured labor... The House of Representatives passed the bill last year... 

Kenneth Kennedy, a senior policy adviser for [U.S. Immigration and Customs Enforcement], has called the loophole “the Achilles heel” of the Tariff Act. To illustrate his point, he...[cited] problems with the cocoa industry... “If we know cocoa is being produced on plantations in West Africa using slave labor, and then being imported into the U.S., we still have to allow it in [under the existing law] because the U.S. cannot produce enough cocoa to meet U.S. demand,” Kennedy said...
