While finalised numbers have yet to be released, the port estimated volumes would total 890,000 TEU for April.

"A bit lighter compared to last year's torrid pace, but still strong numbers by any measure," said port executive director Gene Seroka.

Imports totaled 459,918 TEU, down 6.2 per cent on the year. Empties were down two per cent decrease, remained well above pre-Covid averages at 334,852 TEU.

Soaring empty exports are indicative of ongoing national trade challenges, Mr Seroka said, adding that efforts are needed to boost exports and ensure accessibility to US export shippers.

Cargo is still finding its way out of ports throughout central China," he said. "So far, there's been no dramatic change in number of vessels leaving China since lockdowns six weeks ago."

The port projects May and June volumes to come in at the mid- to upper 800,000 TEU range.

"While conditions could change, I don't foresee a bust coming in transpacific trade. More likely, we may see a lull in volume with a fairly quick bounceback when the lockdowns end. If this lockdown goes deeper into May or June, these are issues we're going to have to grapple with," said Mr Seroka.
