Dylan Geraets is an associate in Mayer Brown's Public Policy, Regulatory & Political Law and International Trade practices in Brussels. He advises clients on a wide range of issues in the field of international trade. His practice focuses on international dispute settlement, trade defence measures, customs rules, trade negotiations, export controls, and sanctions. Dylan represents clients in WTO dispute settlement proceedings and in proceedings before the Court of Justice of the European Union.

Dylan is experienced in advising and representing both multinational companies and sovereigns in respect of proceedings before WTO panels and the Appellate Body. In addition, he has experience in assisting clients in trade remedy investigations, such as anti-dumping and safeguard investigations. In this context he has been involved in several cases before the Court of Justice of the European Union.

On a daily basis, Dylan advises clients on the interpretation of rules and procedures impacting trade in goods and services. This includes the provision of advice on customs matters such as rules of origin, tariff classification, customs valuation, and the applicability of special custom procedures. In this regard, he had advised clients in respect of proceedings before customs and other relevant authorities of several EU Member States.

Dylan regularly advises clients on the implications of the EU’s export control regime in relation to certain dual-use goods and other sanctioned items. In addition, he has experience in advising clients in respect of their day-to-day sanctions compliance efforts under the EU sanctions regime, as well as with respect to the implementation of sanctions imposed by the United Nations.

His doctoral dissertation entitled “Accession to the World Trade Organization: A Legal and Normative Analysis” was published in 2018 with Edward Elgar Publishing.
