What is the term for any parcel suspected of containing mailable or prohibited HAZMAT that is not properly packed, labeled, or identified?

The term "undeclared" refers to any parcel that is suspected of containing hazardous materials (HAZMAT) but has not been properly identified, packaged, or labeled according to postal regulations. This designation is crucial because it highlights the potential risk that such parcels pose if they are not handled correctly. Mail carriers and postal services require accurate labeling and declaration of these items to ensure safety and compliance with regulations governing the transport of hazardous materials.

In contrast to "undeclared," a "declared" parcel would have the necessary documentation indicating its contents, while "non-hazmat" refers to parcels that do not contain any hazardous materials. The term "prohibited" applies to items that are entirely banned from being mailed, regardless of their HAZMAT status. Understanding these distinctions helps postal employees identify and manage parcels correctly, especially when it comes to adhering to safety protocols and shipping regulations.
