ArentFox Schiff‘s international trade and investment group, which is chaired by David Hamill out of Washington DC but consists of lawyers spread across the US, assists with a range of customs, export controls and economic sanctions-related issues. New York-based Angela Santos leads the customs practice, which is sought out by clients for classification, value and origin advice, often in the automotive, fashion and consumer products industries. Sylvia Costelloe, based in Los Angeles, spearheads the export controls subgroup, which deals with a variety of issues related to EAR, ITAR, and OFAC sanctions and embargoes. Kay Georgi has a wealth of experience navigating export control and sanctions issues for large companies, as does another key lawyer in the team, Christopher Skinner.
