Just figured I'd post this for anyone else that's outside the US and ordering from SPD. Their policies for orders outside the US make it a bit risky.
I ordered 15 Seagate Ironwolf Pro 18tb drives with 5 year warranties.
One of the boxes had 100% DOA drives.
The other two had a mix of dented (but working) drives.
In total about 50% of the drives I got from them were either completely dead or dented.
They won't do an exchange because I'm in Canada. All they can do is a refund, where I can order the same drives again at a much higher price.
Overall this was my first experience with them, and it's been a huge let down, I basically have to return/refund all of the drives and go shopping again. My plan was to run 11 drives in raidz3 (and use the others for backups etc), and that's off the table with this many dead.
So buyer beware if you're outside the US, you may end up with a lot of dead drives and a headache having to return them.
I'll provide an update once I have full resolution, but I'm half expecting there to be issues with just getting a full refund even because of duties and taxes.
Edit:
I ordered the ones mentioned in this post:
