Jeffrey I. Kessler is a partner in WilmerHale’s International Trade Practice, where he handles some of the most high-profile work in the international trade arena.  Mr. Kessler originally joined the firm in 2011 and rejoined in 2021 after serving for two years as Assistant Secretary for Enforcement and Compliance at the US Department of Commerce, the chief trade enforcement official for the US Executive Branch.

As Assistant Secretary for Enforcement and Compliance, Mr. Kessler headed the 360-person office that enforces the US antidumping and countervailing duty laws, monitoring foreign compliance with trade agreements, supporting the negotiation and implementation of international trade agreements to open foreign markets, administering the Foreign-Trade Zones program, and evaluating Section 232 steel and aluminum tariff exclusion requests. Mr. Kessler was the decisionmaker in hundreds of trade remedies cases, renegotiated a series of politically charged trade pacts with foreign countries and producers, and spearheaded the largest overhaul of Commerce’s trade enforcement regulations in decades. His tenure as Assistant Secretary represents a high-point in Commerce’s trade enforcement activity, with the most ever trade remedy investigations in a single fiscal year (104), as well as several self-initiations of circumvention proceedings, and the first-ever countervailing of foreign currency undervaluation.

At WilmerHale, Mr. Kessler represents US manufacturers in high-profile trade remedy cases, including those related to fertilizer products, softwood lumber, and chemicals and plastics products. Mr. Kessler advises on both the legal and the political aspects of such cases. He regularly appears before the US Department of Commerce, the US International Trade Commission, and the US Court of International Trade. Mr. Kessler has also been involved in successfully litigating several precedent-setting cases before WTO panels and the Appellate Body, including US – Large Civil Aircraft (2nd complaint) (Article 21.5 - US), EC and certain member States – Large Civil Aircraft (Article 21.5 – US), US – Tax Incentives, Argentina – Import Measures, and Brazil – Certain Measures Concerning Taxation and Charges

A particular area of emphasis for Mr. Kessler’s practice is China. Mr. Kessler has assisted leading US companies and industry associations—especially those in innovative, IP-intensive industries—to understand and navigate Chinese trade and investment barriers. Mr. Kessler has advised companies on issues such as China's sector-wide subsidy programs, IP policy and enforcement, cyber sovereignty and related policies, technology transfer requirements, national security–related technical standards, and restrictions on the supply of foreign services.

Mr. Kessler advises clients on a wide range of other trade issues, including: recent US and foreign sanctions measures against Russia; the consistency of such sanctions with WTO and other international rules; the EU’s digital sovereignty agenda (including the Digital Markets Act, the Digital Services Act, the Data Act, etc.); strategic challenges that global companies face in doing business both in the US and China; compliance with issues related to forced labor, including the Uyghur Forced Labor Prevention Act; possible de-listing of Chinese companies from US stock exchanges pursuant to the Holding Foreign Companies Accountable Act; recent developments in global competition law; climate change policy, including proposals for a carbon border adjustment measure; the Indo-Pacific Economic Framework; the US proposed outbound investment screening mechanism; Section 301 tariffs and exclusions; and international trade-related aspects of large corporate transactions. 

Mr. Kessler is a frequent speaker on international trade topics, including at leading law schools and industry associations. Mr. Kessler earned his BA magna cum laude (Philosophy and Classics) from Yale University in 2005, an MA (Philosophy) from the University of Chicago in 2007, and a JD and MA (Economics) from Stanford University in 2010, where he was an Articles Editor of the Stanford Law Review and a John M. Olin Law and Economics Fellow. Mr. Kessler is a member of the American Bar Association and a Term Member of the Council on Foreign Relations.
