The quiet hand behind global trade

Lighthill is a boutique international trade law firm in Washington, D.C. We counsel producers, importers, exporters, and governments through the most complex regulatory terrain in global commerce.

Precision where the stakes are highest

Our attorneys and advisors have defended clients in antidumping and countervailing duty proceedings before the Department of Commerce, represented clients in import injury investigations before the International Trade Commission, litigated before the Court of International Trade, and prepared clients for and participated in on-site verifications in AD and CVD proceedings worldwide. Our work has also included representing clients in submitting comments to the Bureau of Industry and Security in Section 232 national security investigations and to the Office of the U.S. Trade Representative in Section 301 investigations into foreign trade practices.
