Fwiw Iron Flask is half the price, and pretty much the same quality. If you're set on HydroFlask, looks like even the smallest ones are way over the PEB limit. I'd try a DNA, test the waters, if it fails, just tell them someone else picked up the box and you didn't know, and return it for a normal refund? I always just try to DNA, and if they're not down for it, try again with another method, although dry ice boxing seems like overkill for a water bottle.
