WASHINGTON, April 29 (Reuters) - U.S. President Donald

Trump will sign an order giving automakers building vehicles in

the U.S. relief from part of his new 25% vehicle tariffs to

allow them time to bring parts supply chains back home, Commerce

Secretary Howard Lutnick said on Tuesday.

Automakers would receive credits for up to 15% of the value

of vehicles assembled in the U.S. that could be applied against

the value of imported parts, Lutnick told reporters.

Autos and parts subject to the 25% Section 232 autos tariffs

would no longer be subject to other tariffs imposed by Trump,

including 25% duties on Canadian and Mexican goods, as well as

10% duties applied to most other countries.
