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.
