To everyone: We are all seeing significantly different lengths of time--e.g., 6-14 days--for shipment from Harumio to North America (say the US).
I think (but do not know) that this depends in part on weekends, down-time at various shipment hubs like airports and shipping company facilities, and (of course) the location of the final destination.
Some clever person could probably figure out the best time and day-of-the-week to ask for an invoice or to make the payment, but otherwise it is probably just the luck of the draw. Some people get lucky with incredibly short deliveries (probably because all the pieces fall into place in a timely fashion). For others it takes longer.
For example for my 12-day (purchase-to-delivery) experience, after leaving Seoul the package first went to LA, then to San Francisco, and then to Sacramento, before being put on a van for delivery. At each place there was some level of down-time, depending on when the next flight was scheduled to the particular place it had to go. If it missed a connection at one place, it had to wait for the next scheduled flight, which might not be until the next day.
Bottom-line? Patience is required.

I've read comments that some people expect this "Golden Age" of ordering the CCS1 adapter to end soon--ostensibly because Tesla will "get wise" and put a stop to it. Could be. Meanwhile it is very interesting to see how Harumio's online distribution mechanism, for example, is rapidly evolving to handle purchasing and shipping--how it is ever easier to order the adapter, and now other Tesla-related items. Some have speculated that Tesla is already wise to the whole thing and may even be consciously playing a part in this back-door distribution. Don't know about that. But this "pirate" process is getting adapters into the hands of those (relatively few, I guess) impatient North American customers that need and want them now, and with seemingly very little liability on Tesla's part should anything go wrong. (For example, Tesla doesn't have to worry about people whose cars do not work with the adapter. "That's entirely on you," Tesla would be able to say.)
