Jeasus - seriously - if that was an inbound shipment then it would be worse - this appears to have been leaving - which would infer that the TEUs were more empty than full.
I would expect they're as close to full as they can get in every trip. They'd be terribly inefficient ways to transport goods otherwise.
Some import products are crazy cheap because cross-planet shipping is basically free because it's the reverse end of a trip carrying valuable stuff. But they mainly applies to ships returning from low development level regions.
Most our exports are bulk not container afaik
Unless ImportYtei.com can get the bills of lading for that ship....
