U.S. President Donald Trump will sign a directive in the coming days raising his global tariff to 15% “where appropriate” and is seeking “continuity” with nations that struck trade deals, U.S. Trade Representative Jamieson Greer said.

“So right now, as we talked about, 10% is in place. There will be a proclamation raising it to 15% where appropriate,” Greer said Wednesday on Bloomberg Television’s Surveillance program.

Greer sought to clarify how the administration would follow through on Trump’s threat to hike the rate to 15%, which added to U.S. trading partners’ confusion in the wake of the Supreme Court’s nixing of his so-called “reciprocal duties.” A 10% worldwide levy took effect Tuesday, and in the ensuing 24 hours, the administration offered few details about how it would follow through on the president’s threat while honoring pacts with major trading partners.
