No, that’s not necessary.
Shipment templates are used to define which types of shipments we should create for you, based on the shipping methods your customers select in your webshop.
A single template can be used for multiple countries, it just needs to be mapped to the relevant shipping methods from your webshop. When a shipment is created, the country code is automatically replaced with the country code of the order. This means that a template created for Germany, for example, can be used across the EU, as long as all other details remain the same.
Country-specific templates are only needed if there are special requirements that must be considered.
