WASHINGTON, July 30 (Reuters) - The U.S. Trade

Representative's office said Tuesday some of the steep U.S.

tariff increases on an array of Chinese imports, including

electric vehicles and their batteries, computer chips and

medical products will be delayed by at least two weeks.

The USTR in May said those tariffs would take effect on Aug.

1 but the office said Tuesday it is still reviewing 1,100

comments received and now expects to issue a final determination

at some point in August. The office added the new tariffs will

take effect approximately two weeks after the final

determination is made public.
