Which combination of labeling and declaration is required for UN3480 Section IB shipments?

• A. Only labeling is required; no declaration
• B. Only the Shipper's Declaration is required
• C. Both labeling (including UN number and shipper/consignee) and the Shipper's Declaration with net weight and IB designation
• D. Neither labeling nor declaration is required

Answer: (C)

UN 3480 Section IB shipments require both labeling and a Shipper’s Declaration. The labeling must clearly show the UN number (UN 3480) and identify the shipper and consignee, along with other handling details so that anyone handling the package knows exactly what it is and how to treat it. The Shipper’s Declaration accompanies the shipment and certifies that the package complies with the Section IB packing instruction, including the exact net weight and the IB designation. This combination ensures regulators and carriers can verify the hazard, the quantity, and the specific packaging requirements, providing both identification and documented compliance. Without labeling, handlers can’t quickly identify the hazard; without the declaration, there’s no official proof that the shipment meets the required safety packaging and quantity standards.
