The Port of Los Angeles remains largely unaffected by supply chain disruption caused by US-Israel attacks on Iran that have escalated into regional conflict, its executive director Gene Seroka said, reported Reuters.

Mr Seroka said congestion has not spread to the transpacific trade, which is the port's mainstay. Most of the 40 container services at Los Angeles run direct routes to Asia and are unconnected to Middle East shipping.

He added that manufacturing flows serving the US, Europe and Latin America continue to move. Port data showed imports rose five in February compared with a year earlier, as retailers and manufacturers shipped goods ahead of Chinese New Year.

February volumes reached the second-highest level in port history, with exports up nearly seven per cent. The port handled 824,323 TEU in total, including 433,812 TEU of imports, 116,633 TEU of exports and 273,878 TEU of empties.

Mr Seroka said the port is entering its traditional slack season, with first-quarter throughput expected to fall by mid-single-digit percentages compared with last year, when importers rushed goods to beat new tariffs.

He noted replenishment of inventories, particularly spring and summer fashion, is expected. Uncertainty from the Iran war has not led US importers to cancel seasonal apparel orders, which he described as a positive sign.
