SAO PAULO, Aug 6 (Reuters) - Brazilian lender Itau

Unibanco ( ITUB ) does not expect tariffs imposed by the

United States on some goods from Brazil to have an impact on the

bank's credit portfolio, Chief Executive Milton Maluhy Filho

said on Wednesday.

Potential impacts are immaterial and the company conducts

detailed mapping of the segments, Maluhy Filho told a press

conference after the bank reported its second-quarter results.

"So far, we are very comfortable with it," he added.
