Tiffany Smith is a senior policy advisor and member of Mayer Brown’s International Trade & Public Policy, Regulatory, and Public Law practices, where she advises companies, trade associations, and non-profits on developing strategies for achieving clients’ objectives.

Tiffany’s experience at Mayer Brown includes:

  • Helping clients to assess the consistency of various rules and regulations with World Trade Organization (WTO) rules and other international legal obligations.
  • Assisting clients in developing positions for international trade negotiations in the WTO and bilateral or regional fora.
  • Working with clients to ensure the correct tariff classification of goods, compliance with rules of origin requirements, and to identify potential duty savings through the use of duty preferences under bilateral and regional trade agreements, and special duty programs such as duty drawback and Miscellaneous Tariff Bills (“MTBs”).
  • Representing clients’ industries affected by WTO dispute settlement proceedings in Geneva, including a successful challenge to US restrictions on clove cigarettes. This case was selected as the “Global Dispute of the Year: International Litigation” in The American Lawyer’s inaugural Global Legal Awards in 2013.
  • Advocacy on behalf of clients to the U.S. and foreign governments. 

Prior to joining Mayer Brown in 2007, Tiffany worked for 16 years in the Federal Government, serving in positions in the Executive Office of the President, the United States Senate, and the Department of Commerce.

During her tenure at USTR, Tiffany led market access negotiations for consumer and industrial products during nine Free Trade Agreements (Korea, Malaysia, Oman, UAE, Panama, Colombia, Peru, Dominican Republic and Bahrain) and for Saudi Arabia and Vietnam’s accessions to the WTO. Tiffany was instrumental in developing the United States’ positions on expanding trade in key industry sectors, including chemicals, electronics, forest products and information technology, that later determined international negotiating strategy. Her work has made a global impact through establishing policy, sustaining the opportunity for negotiations and concluding international agreements.
