President Donald Trump has extended a waiver that permits foreign-flagged ships to transport commodities between U.S. ports for 90 days.

On Monday, the waiver extension was introduced with new limitations due to concerns from shipbuilders and Congress about the policy's adverse impact on the domestic maritime industry.

The extension, until mid-November, is intended to ensure uninterrupted access to vital resources for the U.S. military and key industries.

White House Deputy Press Secretary Taylor Rogers stated on Monday that the waiver has resulted in a significant increase in domestic deliveries of essential products such as gasoline, diesel, and jet fuel.

The 1920 law otherwise requires vessels transporting goods between U.S. ports to be U.S.-built, U.S.-flagged, and staffed by U.S. crews.
