Just so you know, the paperwork is separate from the actual box(es). The box is shipped via boat in a container from China to a port in or near your country, on the shipping status page that SM presented to me, it says this:
Note: Your order is/will be (please refer to the order status) shipped by sea. If you are located in the United States or Australia, the shipping time is approximately 30-45 days. We will provide your tracking number 25-35 days after your order is shipped.
If you are located in Canada, the shipping time is approximately 45-65 days due to stricter customs during the pandemic. We will provide your tracking number 40-50 days after your order is shipped.
Important update: Due to safety measures taken by the customs in some countries during COVID-19, it takes a longer time for packages to clear the customs. Your package might be delayed for 7-14 days.
That means that for the USA it will take up to 45 days to get to the port. As a separate process the customs paperwork is created for importation into your country. That’s what the email you received was about. Your SM may not actually have arrived at this point. 45 days puts it at 13 December for arrival in port - if nothing else happens along the way. Given the proximity to christmas and the global pandemic I’d be surprised if it takes as little as 45 days.
Then, once it’s arrived in port it will go through customs, which takes time that’s not fixed either. The above information indicates up to a fortnight to clear customs, but given the time of year, probably more.
Then, and only then, will FedEx actually get notified that they can put their hands on the package and start the process of getting it to you.
I’m in the same position, in a different country and over here I can expect it to take at least three weeks to get from one end of the country to the other - since the local shipping companies appear to be using goats rather than modern forms of transport.
So, you can start arguing with your credit card company, or you can be patient.
I for one will be thrilled if my SM arrives before Australia Day.
