Woodside Energy Group (ASX:WDS) said it is evaluating the potential effects of US tariff announcements and future trade measures on the Louisiana liquefied natural gas (LNG) project, according to a Wednesday filing with the Australian bourse.

Roughly 25% of the project's estimated capital expenditure is equipment and materials, half of which is expected to come from the US, the filing said.

The project operates under a foreign-trade zone, allowing it to delay tariff payments until the completion of each LNG train, per the filing.

Shares were up 3% in midday trade Wednesday.
