My R32 is due for import this month. I had all the docs ready to mail off on october 1. But geoff from prestige emailed me and said i could fax them off early(think it was about 25 september) so i rang dotars and asked firstly could i fax it, they said that was fine, then i asked them if i could send it early and the lady said there is no problem with that too. So i faxed it off in september then rang dotars a couple of days later to make sure they had recieved it.
My import approval arrived in the mail a couple of days ago(approx 17 business days from when i faxed it)
So i'm sure if you send it off a little earlier there is no problem, i wouldn't risk sending it off months earlier as may get 'lost'
Now i gotta get the dam thing on a ship, geoff said he was having it booked on the next available ship(that was about 5 weeks ago) spoke to him the other day and he has not recieved the schedule from the supplier yet so who knows whats happening.
