Which statement about EPA Hazardous Substances shipments is true regarding RQ and technical names?

• A. The RQ value must be listed after the technical name
• B. The lowest RQ value must be listed first
• C. RQs are not required
• D. Technical names are optional

Answer: (B)

Shippers must identify EPA Hazardous Substances on the shipment papers by listing the technical name of each substance and its Reportable Quantity (RQ). When more than one hazardous substance with an RQ is present, the items should be arranged in order of increasing RQ, so the smallest RQ appears first. This ordering makes it quick to see the lowest threshold that could trigger reporting and keeps documentation consistent when multiple substances are involved. The technical name is required to identify the substance precisely, and the RQ values are required to indicate reporting thresholds.
