The Commerce Department is expected to deliver a long-awaited report to the White House on Sunday on whether the administration should enact tariffs on autos and auto part imports in order to protect domestic manufacturers. The business community and trade partners such as Japan and the European Union have been bracing for the report for months.

The official deadline for the department to present the report is Feb. 17, and that date remains in effect despite speculation that last month’s federal government shutdown may have pushed it back, according to people with knowledge of the deliberations. The details of the report have been kept closely under wraps, and it is not clear when the White House will make it public. An official with one stakeholder group speculated it could remain privileged for weeks.
