The Jones Act limits shipping between U.S. coasts to U.S. flagged vessels and is backed by shipping and security interests. Opponents of the law say it adds costs to shipping of basic goods such as fuel, food and clothing to Puerto Rico and Hawaii that are passed on to consumers.

“We believe that extending the waiver is unnecessary to support the humanitarian relief efforts on the island,” said David Lapan, a Homeland spokesman.

Lapan said Homeland has not received any requests from commercial interests to waive the Jones Act and that the Department of Defense has not requested an extension of the waiver.

“There is an ample supply of Jones Act-qualified vessels to ensure that cargo is able to reach Puerto Rico,” Lapan said.
