Self-handling is explicitly allowed as Article 7 of Council Directive 96/67/EC of 15 October 1996 on access to the ground handling market at Community airports establishes that Member States shall take the necessary measures to ensure the freedom to self-handle. However, in case of non-EU suppliers, this is subject to the application of the reciprocity principle (see Article 20 of the Directive). Furthermore, Member States may reserve the right to mail handling to no fewer than two airport users chosen on a non-discriminatory basis. Italy restricts cargo-handling in airports with more than 1 million passengers per year or 25,000 tonnes of goods transported.
