A Mexico-based manufacturer of container chassis plans to end US sales after the decision from US trade officials in June to slap hefty duties on imported chassis from that country.

GG Trailers said in a statement to the Journal of Commerce that it is “exiting the US intermodal market following the antidumping and countervailing duty proceedings initiated by domestic chassis manufacturers.”

“As part of this process, we are liquidating more than 180 new 40-foot chassis currently located in Mexico,” the company said in the statement. It was not clear if that meant GG was ceasing all operations; a company official could not be reached for additional comment.

The move to exit the US market follows the International Trade Commission’s (ITC’s) June decision to impose a 77% countervailing duty on chassis imported through Mexico. Chassis from Mexico were also subject to the Trump administration’s 25% tariff on steel derivative products.

The ITC began an investigation into chassis from Mexico, Thailand and Vietnam in February 2025 that found manufacturers in those countries sold chassis in the US “at less than fair value” and that Mexico’s government subsidized its chassis industry.

Established in 2021 through a partnership between Mexican conglomerate GIM and US railcar maker Greenbrier, GG was one of many overseas suppliers that entered the US market during the pandemic. The ITC identified 16 overseas companies that entered the US chassis and truck trailer market after 2022.

With demand normalizing, chassis and truck trailer imports have fallen from $14.8 billion at the end of 2023 to $11.3 billion by May, according to Supply Chain Intelligence from S&P Global. The extra supply coming into the market also drove down chassis prices, with the 12-month average import value of a chassis or truck trailer going from $1,886 in January 2022 to $459 at the end of May.

“We hope US supply capacity will be able to respond quickly when the next major surge in demand arrives,” GG Trailers said in its statement.
