General order merchandise: how long before it can be sold?

Hagen Industries Limited (“Hagen”) imported two containers of 1000-piece jigsaw puzzles from Poland, and is identified as the consignee on the bill of lading for the shipment. The puzzles were transported to the Port of Los Angeles-Long Beach by vessel. Twenty (20) calendar days after arrival and unlading at the port, no entry had been filed for the puzzles. The port director properly took custody of both containers and deposited them in a general order warehouse at Hagen’s expense. How long from the date of importation can the puzzles remain in the warehouse before they become subject to sale?
