What is the overall purpose of marking and labeling along the hazmat supply chain?

• A. To communicate hazards, packaging type, and handling requirements to all parties along the supply chain
• B. To determine shipping costs
• C. To identify the shipper's address
• D. To enforce import quotas

Answer: (A)

Marking and labeling in hazmat shipping is about clearly communicating what the material is and how it must be handled. It conveys hazards, the packaging type, and any specific handling or storage requirements to everyone involved in the supply chain, from shipper to carrier to recipient and even emergency responders. This shared information helps ensure safe transport, proper segregation, and regulatory compliance, so people know how to move, store, and react if something goes wrong. The other options don’t fit because marking and labeling aren’t used to set shipping costs, identify only the shipper’s address, or enforce import quotas.
