There are currently no tariffs or quotas on titanium sponge imports.
The Department of Commerce announced March 4, 2019 its initiation of an investigation under section 232 of the Trade Expansion Act of 1962 into whether the quantity or circumstances of titanium sponge imports into the U.S. threaten to impair national security. This investigation was launched in response to a petition filed by domestic producer Titanium Metals Corporation. In November 2019, the department determined that imports of titanium sponge are threatening to impair national security.
A February 27, 2020 presidential memorandum declined to take actions to adjust imports.
A working group was formed to agree upon measures to ensure US access to titanium sponge for use for national defense or in the event of an emergency. In January 2021, the working group sought public comments to better inform their deliberations.
