TOKYO, Sept 9 (Reuters) - U.S. tariffs on Japanese goods

including cars and auto parts are set to be lowered by September

16, Japan's tariff negotiator Ryosei Akazawa said on Tuesday.

Citing a U.S. Federal Register document dated September 9

that formalised President Donald Trump's executive order on the

U.S.-Japan trade deal, Akazawa said in a press conference the

revised tariff rates on Japanese goods will take effect within

seven days from its publication.

Washington struck a trade deal with Tokyo in July, agreeing

to reduce tariffs to 15% on Japanese goods, including autos, in

exchange for a $550 billion package of U.S.-bound investments

and loans.

Trump's signing of the order last week resolved some

uncertainty over when the lower tariffs would be implemented.

But Akazawa reiterated on Tuesday that the trade talks have

not been "settled", saying that the most-favoured-nation status

for pharmaceuticals and semiconductors has not been included in

the executive order.

A separate joint statement released last week said Japan

would consistently receive the lowest tariff rates on chips and

pharmaceuticals among all trade agreements negotiated by

Washington. However, Akazawa said Japan would continue to urge

the U.S. to formalise the commitment through an executive order.

Asked if the $550 billion investment package could be used

to finance Nippon Steel's U.S. Steel deal or SoftBank Group's ( SFTBF )

planned projects, Akazawa said it would be up to the

U.S. to select which initiatives receive funding.
