If "RQ" appears before or after an item description on shipping papers, what is required of the carrier?

When "RQ" appears on shipping papers, it stands for "Reportable Quantity." This designation indicates that the substance being transported is hazardous and that there are specific requirements for handling it. The primary obligation for the carrier in this case is to report any spill or release of the material that meets or exceeds the reportable quantity threshold. This requirement is crucial for ensuring public safety and environmental protection, as spills can have significant consequences.

In contrast, the need to notify the sender, perform a safety inspection, or label the package clearly, while important in certain contexts, does not specifically relate to the "RQ" designation. The focus is on the responsibility to report incidents involving the material, ensuring that proper protocols are followed in line with regulatory standards for hazardous materials.
