What does the acronym SDDG stand for in hazmat shipping?

• A. Shippers Declaration for Dangerous Goods
• B. Shippers Documentation for Dangerous Goods
• C. Shippers Declaration for Dangerous Goods Form
• D. Declaration for Dangerous Goods

Answer: (A)

SDDG stands for Shippers Declaration for Dangerous Goods. This is the formal document the shipper signs to certify that the dangerous goods being offered for transport comply with all applicable hazmat regulations. It accompanies the shipment and is used by carriers and authorities to verify proper classification, packing, labeling, and documentation. The declaration includes the shipper’s information, the transport mode, the UN number, the proper shipping name, hazard class, packing group, total quantity, number of packages, and the shipper’s certification and signature. In hazmat shipping, this declaration is a key piece of paperwork required for many modes of transport, especially air, to ensure safety and regulatory compliance. The other phrasings don’t reflect the standard terminology: they use “Documentation” or “Form” instead of the established “Declaration” and omit the word “Shippers” which is part of the formal title.
