WASHINGTON, Aug 28 (Reuters) - The U.S. tariff exemption

for package shipments valued under $800 ends permanently on

Friday, with a six-month transition period under which postal

service shippers can opt to pay a flat duty of $80 to $200 per

package depending on the country of origin, Trump administration

officials said on Thursday.

The U.S. Customs and Border Protection agency will begin

collecting normal duty rates on all global parcel imports,

regardless of value after 12:01 a.m. EDT (0401 GMT) on Friday.

The move broadens the Trump administration's cancellation of the

de minimis exemption for shipments from China and Hong Kong

earlier this year.

"President Trump's ending of the deadly de minimum loophole

will save thousands of American lives by restricting the flow of

narcotics and other dangerous prohibited items, and add up to

$10 billion a year in tariff revenues to our Treasury," White

House trade adviser Peter Navarro told reporters.
