The NACE structure developed at EU level and including the 4-digit Class level and above is used by all EU Member States. However, some countries decide to add a 5-digit Subclass level to their national version of NACE to describe their economic activity at a more detailed level. The Subclasses created vary from one Member State to another. Each country that decides to add a 5-digit Subclass level performs its own consultation of national interests, in its own way, and then creates Subclasses based on the feedback received.
