Mr. Biden is set to give a speech on Wednesday addressing the problems in ports, factories and shipping lanes that have helped produce shortages, long delivery times and rapid price increases for food, televisions, automobiles and much more. The resulting inflation has chilled consumer confidence and weighed on Mr. Biden’s approval ratings. The Labor Department is set to release a new reading of monthly inflation on Wednesday morning.

Administration officials say that they have brokered a deal to move the Port of Los Angeles toward 24/7 operations, joining Long Beach, which is already operating around the clock, and that they are encouraging states to accelerate the licensing of more truck drivers. UPS, Walmart and FedEx will also announce they are moving to work more off-peak hours.

Mr. Biden’s team, including a supply chain task force he established earlier this year, is working to make tangible progress toward unblocking the flow of goods and helping the retail industry return to a prepandemic normal. On Wednesday, the White House will host leaders from the Port of Los Angeles, the Port of Long Beach, and the International Longshore and Warehouse Union to discuss the difficulties at ports, as well as hold a round table with executives from Walmart, UPS and Home Depot.
