If "RQ" appears near the item description on shipping papers, what does it mean?

When "RQ" appears near the item description on shipping papers, it signifies "Reportable Quantity." This notation indicates that the material has a specified quantity threshold that, if exceeded, obligates the carrier and others involved in the shipping process to report any release of the substance to the appropriate authorities. This requirement is crucial for ensuring safety and compliance with environmental regulations, as it helps in the assessment and management of any potential hazards posed by the material.

This designation does not imply that the item is exempt from hazardous materials regulations, nor does it mean that no special handling is required or that the item is of low risk. Instead, it highlights the importance of monitoring and managing the transportation of materials that could pose significant risks to health and the environment if released.
