Is there a way of adding an order value limit to people from specific countries?
For example, if a customer is ordering from France - the max value limit is €140 per order and they would need to start a separate order if they’d like to order more.
The shipping rules that you are trying to achieve are unfortunately not available in Shopify. However if you are open to using an app then I would suggest you to check out Multi Carrier Shipping Label App. This app allows you to set shipping zones and order value limit based on your requirement. You can create multiple rules & completely automate your shipping process.
