He is highly experienced in international trade disputes (i.e. anti-dumping, countervailing duty, safeguard, and 337) related to imports to the U.S., EU, and the PRC. His hands-on approach and ability to quickly understand a client’s business and operations has consistently enabled his team to achieve favorable results in complex trade cases. Besides questionnaire responses related to sales, production and accounting as well as on-site verifications, David helps clients to improve their operation and management systems and helps shape their business structure with long term strategic planning.

David has been advising multinational clients on general corporate and customs since 2000. He assists clients from the very beginning when they first invest into China, to their daily operations and regulatory compliance matters. Clients always find his advice precise, clear and helpful.

David’s practice also covers the full spectrum of customs matters, including classification, valuation, free trade zones and bonded warehouses, import licensing, export control, audits and investigations as well as US export control.

David has developed unique investigative and auditing expertise from his trade litigation practice, and assists clients in navigating Chinese anti-bribery laws and the U.S. Foreign Corrupt Practices Act, and frequently assists clients in internal investigations, audits, and preventative training.
