So you are saying Berlin might have an initial burst of output and then run out....They aren't shipping these packs by rail.
They are too heavy to fly cost-effectively. Even ignoring the haz freight issue.
So they are going in ships. Or more accurately, most of them that are/were intended for use in Berlin during Q2 have already departed from Shanghai in ships even if they have not yet arrived.
i.e. pre Shanghai lockdown.
(steaming time Shanghai-Rotterdam is typically 30d+)
