What does 49 CFR Part 453 address?

49 CFR Part 453 focuses on the control and enforcement of container standards, ensuring that intermodal containers meet the required safety and compliance criteria set forth by regulatory authorities. This part of the Code of Federal Regulations outlines the responsibilities of various parties involved in the intermodal container lifecycle, including manufacturers, shippers, and certifying bodies.

By establishing a framework for these standards, 49 CFR Part 453 helps ensure that containers used in transport are secure, structurally sound, and compliant with international shipping regulations, thereby reducing the risk of accidents and ensuring safety in transportation.

The other options refer to different aspects that may relate to container use or transportation but do not encapsulate the primary focus of 49 CFR Part 453. For instance, marking standards, size specifications, and shipping insurance premiums each touch on separate regulations or considerations that are not addressed directly within this specific part of the federal regulations.
