• Greenbrier is challenging a U.S. Customs and Border Protection determination under the Enforce and Protect Act on freight rail couplers, issued May 18 in EAPA Case 8183.
• The ruling reclassifies railcars and related parts in a way Greenbrier says breaks with decades of agency practice, raising the risk of new tariff exposure and compliance burdens for cross-border rail operations.
• Greenbrier warned the move could disrupt North American rail interchange flows, lift supply-chain transportation costs, and feed through to higher prices for U.S. businesses and consumers.
• The company is evaluating options for administrative review or litigation while continuing to cooperate with CBP.
