Are packing group 2-3 corrosives transported under the limited quantity provision?

• A. No
• B. Yes
• C. Only under certain weight scenarios
• D. Not allowed

Answer: (B)

Limited quantity provisions are all about allowing small shipments of dangerous goods to move with simpler packaging and labeling. For corrosive substances that are packing group II or III, these goods can be transported under the limited quantity rules as long as the package meets the specified LQ limits and uses the appropriate UN packaging with proper inner and outer packaging. The key is that the quantity per package and the labeling requirements must align with the IATA DGR limits for LQ, and the substance must be in packing groups II or III. When those conditions are met, yes, these corrosives may be shipped under the limited quantity provision, which is why that option is the best choice. The other options would be incorrect because the availability of LQ for PG II/III corrosives is not ruled out outright by their classification, nor is it solely determined by weight alone; it depends on meeting the LQ criteria and packaging standards.
