July 30 (Reuters) - Car sector-specific tariff deals

with the United States are "very uncertain", Mercedes-Benz

CEO Ola Kaellenius told analysts on Wednesday,

throwing some cold water on hopes firms may be able to negotiate

individual deals.

The U.S. struck a framework trade deal with the European

Union on Sunday, imposing a 15% tariff on most EU goods - half

the threatened rate - and averting a bigger trade war between

the two allies that account for almost a third of global trade.

"We have been extensively engaged in the conversation that

has been going on between the United States and the EU .. For

all intents and purposes, that global deal for now is it," said

Kaellenius, also the president of Europe's car lobby ACEA.
