Which of the following is a requirement for the transport of Excepted Packages?

The correct requirement for the transport of Excepted Packages is that the package must show the full shipper and consignee address. This is essential because it ensures that both the origin and destination points of the package are clearly identified, facilitating accountability and communication throughout the transport process. Accurate addressing helps in case of any issues during transit and ensures the package can be correctly returned or redirected if necessary.

In the context of Excepted Packages, which are low-risk items that may not require the same stringent regulations as other more hazardous materials, proper labeling with full addresses is still necessary to comply with transportation regulations. It makes tracking easier and provides important information should an incident occur.

The other options do not align with the requirements for Excepted Packages. A Shipper's Declaration, while necessary for certain types of hazardous materials, is not always needed for Excepted Packages. Packages can be shipped via various carriers, not exclusively commercial ones. Lastly, even though Excepted Packages have less stringent labeling requirements, they generally still require proper labeling to ensure safe handling and compliance with regulations.
