PEGGY CHAPLIN LOUIE is Senior Counsel with Sandler, Travis & Rosenberg, P.A., resident in the Washington, D.C., office. She focuses her practice on import and export regulation compliance and international shipping issues. This includes negotiating and structuring international commercial transactions to minimize duties and taxes and comply with federal regulations.

She also represents clients before various agencies concerned with international commerce, including U.S. Customs and Border Protection, the Federal Maritime Commission, the Census Bureau, the Bureau of Industry and Security, the International Trade Administration and the Office of Foreign Assets Control.

On import matters, she advises clients on classification, valuation, marking, country of origin and preference program matters. She has extensive experience working with clients on internal audits and prior disclosures to prevent penalties and represents them before the government when penalties are assessed.

Regarding export matters, she counsels clients from the application of the Export Administration Regulations and the Foreign Trade Regulations to their international shipments. She works with clients to classify their products correctly and assists them in complying with export clearance requirements. In addition, she represents exporters in investigations conducted by the Office of Export Enforcement and assists them in preparing and filing voluntary disclosures.

On shipping issues, she represents clients before the Federal Maritime Commission. She files license applications for ocean freight forwarders and non-vessel-operating common carriers and represents shippers as well as ocean transportation intermediaries before the FMC in administrative actions.

She is a member of the U.S. roster of eligible candidates appointed by the U.S. Trade Representative to review agency determinations on antidumping and countervailing duty matters under Chapter 19 of NAFTA, and she has been a panelist on several important Chapter 19 cases. She is an arbitrator member of the American Arbitration Association and arbitrates disputes under the AAA’s commercial and international rules.

She holds an LLM in international commercial law from Georgetown University Law Center, a J.D. from the University of Maryland School of Law and a B.S. from The Johns Hopkins University. She is admitted to practice before the U.S. Supreme Court, the Court of Appeals for the Federal Circuit, the Court of International Trade, the Maryland Court of Appeals and the District of Columbia Court of Appeals.
