What is actually being negotiated in accession negotiations?

Upon joining the European Union, Iceland would broadly speaking be subject to the same rules and obligations as other EU Member States.

However, accession negotiations may need to account for special circumstances and key national interests of new Member States, whether through adjustments to EU rules or by securing transition periods.

The same would apply in Iceland's case.
