Weird. Not sure why they'd have to do all that since it's not required. For it to be tax free (for CA at least) you just can't register it in the state for 90 days after purchase. The US can't collect import taxes unless you bring it into the US within 140 days. Neither will apply to me.
Or this is something totally different. I'll ask my CA about it. Maybe that's why they need the 10 days after payment is made to finish the paperwork.
