The Canada Border Services Agency has launched an investigation into container chassis imported from Vietnam by British Columbia-based Ocean Trailer, a spokesman for the agency said.

Both intermodal and multimodal relate to using different modes of transport for a shipment, but there are some key differences between each of them.

Intermodal chassis manufacturers are scaling back production as a result of weak demand as well as a supply overhang, company executives said.

I Squared Capital acquired a majority stake in FlexiVan Leasing Inc., the private equity firm said. As a result, the company said it is merging FlexiVan with American Intermodal Management.

Trac Intermodal, a provider of intermodal marine equipment, has expanded and updated its chassis fleet in the ports of Houston, Mobile, Ala., New Orleans and El Paso, Texas.
