Hi!
The WooCommerce plugin requires the following Server settings for a standard installation:
- PHP version 7.2 or greater
- MySQL version 5.6 or greater OR MariaDB version 10.0 or greater
- WordPress memory limit of 128 MB or greater
- HTTPS support
You will need to consult with your host on the other parts of your request but I would recommend the PHP Post Max Size be set to at least 1 GB since that is directly related to the largest file size that can be contained in one post. It isn’t exactly related to importing but it may have an effect anyway.
The PHP Time Limit will depend on the connection speed between your computer and the host server so try an upload to see if it times out or not. PHP Max Input Vars relates to the number of variables that can be used in a script, so this is really unrelated to uploading to the server.
You can learn more about all of the settings like this in our documentation about the System Status Report:

I hope this helps! If you have any further questions please feel free to reply to this thread and I will get back to you.
Thanks!
