Which form is utilized for land and vessel transportation of hazardous materials?

The correct choice is the DD Form 2890. This form, known as the "DOD Hazardous Material Pre-Shipping Notification," is specifically designed for the transportation of hazardous materials by land and vessel within the Department of Defense (DoD). It ensures that all necessary information about the hazardous materials is properly documented and communicated, facilitating compliance with the relevant safety and handling regulations during transportation.

In contrast, other options serve different purposes. The Shipper's Declaration of Dangerous Goods is a standard document used internationally for the air and sometimes road transport of dangerous goods, but it is not specifically tailored for land and vessel use as the DD Form 2890 is. The DD Form 2781 is utilized for listing hazardous materials for Army operations and not specifically for transportation. Similarly, the DD Form 626 is for the inspection of hazardous materials in transport, but it does not serve as the shipping form itself. Therefore, the DD Form 2890 is the most appropriate and specific form for hazardous materials transport in the context of land and vessel shipping.
