For shipments containing EPA Hazardous Substances, what must be added?

• A. The hazard class only
• B. The Reportable Quantity notation 'RQ' and the Technical Name(s) of the Hazardous Substances; The lowest RQ value listed first
• C. The shipper's insurance
• D. The emergency contact

Answer: (B)

When EPA Hazardous Substances are being shipped, you must include the Reportable Quantity (RQ) notation and the technical name(s) of the substances on the shipping papers. The RQ value shows the quantity that requires reporting or triggers regulatory notification if a release occurs, helping responders understand potential risk. The technical name identifies the exact substance, preventing confusion from common names. If more than one EPA hazardous substance is present, the RQ values should be listed together with the lowest RQ value listed first to keep a standardized, clear order for reporting thresholds. This combination—RQ notation plus the technical names (and the lowest RQ first when multiple substances are involved)—is the required information.
