When governments impose barriers to trade that restrict global supply chains, our team provides businesses timely, practical, and creative solutions through legal, political, and economic strategies to eliminate obstacles, reduce costs, and minimize the harm caused.

John Brew is the co-chair of Crowell & Moring’s International Trade Group and a partner in the firm’s Washington, D.C. office.

John has extensive experience in import and export trade regulation, collaborating with corporations, trade associations, foreign governments, and nongovernmental organizations on customs administration, enforcement, compliance litigation, legislation, and policy matters. He represents clients in proceedings at the administrative and judicial levels as well as before Congress and the international bureaucracies that handle customs and trade matters. John advises clients on all substantive import regulatory issues handled by U.S. Customs and Border Protection and Immigration and Customs Enforcement, such as classification, valuation, origin, marking, tariff preference programs, other agency regulations, admissibility, customs brokerage, Section 321, drawbacks, foreign trade zones, duty recovery programs, import restrictions, quotas, audits, prior disclosures, penalties, investigations, Customs Trade Partnership Against Terrorism and trade compliance programs, importations under bond, the Jones Act, and vessel repairs.

John has assisted clients in a broad array of industries (automotive, aerospace, chemical, e-commerce, energy, pharmaceutical, petroleum, textile, apparel and footwear, food and beverage, agricultural, machinery, equipment, electronics, and household goods), providing creative solutions that enable clients to obtain significant duty savings and mitigate draconian customs penalties.

John’s practice also includes representation of clients in other international trade areas, such as human rights (forced labor, withhold release orders, the Uyghur Forced Labor Prevention Act, modern slavery, and supply chain due diligence); export controls; sanctions; market access; World Trade Organization–related matters; bilateral, multilateral, and regional trade agreements; the Foreign Corrupt Practices Act; anti-boycott, anti-dumping, and countervailing duty actions; short supply proceedings; Sections 201, 232, 301, and 337; and other import relief actions.
