How is the proper shipping name determined?

• A. It is the name listed in 49 CFR 172.101 for the material, selected by the shipper to accurately describe the contents
• B. It is the common name used in the workplace
• C. It is the name of the product's brand
• D. It is the chemical's molecular formula

Answer: (A)

The proper shipping name is defined by the regulatory list in 49 CFR 172.101 and is chosen by the shipper to accurately describe the contents. This standard ensures the hazard class, packaging, and handling requirements are communicated consistently across carriers and to emergency responders. It isn’t simply the common workplace term, the product’s brand, or the chemical’s molecular formula, which don’t provide the standardized description needed for hazmat transport. If multiple PSNs may apply, the shipper selects the one that most accurately matches the material being shipped.
