A trade truce between the European Union and the U.S. looks more likely after U.S. President Donald Trump lowered the level of some of the most contentious tariffs on Thursday.

On the one-year anniversary of the so-called “Liberation Day” tariff package — when Trump rolled out reciprocal tariffs on imports from countries his administration identified as having unfair trade surpluses with the U.S. — the White House announced changes to duties on steel and pharmaceutical items that go some way to assuaging European policymakers’ concerns.

The two sides concluded a deal in Turnberry, Scotland, last year that saw the U.S. impose unilateral 15 percent tariffs on EU imports. That deal is now being ratified on the EU side. Certain outstanding tariffs outside of the 15 percent level, most notably on steel-derived products, remain a point of contention.

European lawmaker Bernd Lange, responsible for the European Parliament’s negotiations on the EU-U.S. trade deal, told POLITICO he believed the Trump administration’s announcement made a final deal more likely.

Lange noted that the U.S. administration had scrapped 50 percent tariffs on many steel derived items, bringing some, like motorcycles, to the agreed 15 percent levels. In other cases, however, a special 25 percent rate applied.

“The US is increasingly adopting a stance of not further breaching the Scotland Deal,” said the EU lawmaker. But, he added, “we wanted a little bit more, so let’s see.”

The White House also confirmed that a 15 percent tariff applied to pharmaceutical imports from the EU, in line with the Turnberry deal, and not the 100 percent tariff applied to products from elsewhere.

Olof Gill, the European Commission’s deputy chief spokesperson, said the Commission was assessing the announcement.

“We will continue to work towards reducing tariffs,” said Gill. “Our priority remains to preserve a stable and predictable transatlantic trading environment, in full respect of the commitments agreed.”

In February the U.S. Supreme Court struck down the Trump administration’s original tariff package and the White House responded by re-imposing across-the-board tariffs on all countries.

That sparked worries among EU lawmakers — who were in the process of pushing the EU-U.S. deal through the European Parliament — that the U.S. might renege on its commitments. Last month, Parliament finally approved a modified version of the deal that made it conditional on the removal of tariffs on steel derivatives.

Now the deal will go into three-way negotiations between the Parliament, the Commission and the Council of the EU before its final approval.

David Kleimann, a trade policy expert with think tank S-Curve Economics, said the “tariff update eases the tariff burden for a considerable amount of EU steel and aluminium derivative exports” when compared to the previous level. However, he added, “it clearly does not satisfy the demands of the European Parliament.”

The U.S. trade department, under Trump, “is once again engaged in identifying the exact pain threshold of its counterpart,” said Kleimann.
