Which statement describes testing requirements after repacking of dangerous goods?

• A. No testing is required after repacking.
• B. The repacked packaging must be tested again.
• C. Testing is optional.
• D. Only a visual check is required.

Answer: (B)

After repacking dangerous goods, the packaging must be retested to confirm it still meets the required performance standards. Repacking can introduce new weak points or alter how the packaging behaves under transport conditions, so a full test ensures the final repacked unit remains leakproof, durable, and compliant with safety rules. The same testing principles apply to the repacked package as to the original certification, because the integrity of the entire packaging system is what keeps the goods safe during shipment. Visual checks alone can miss hidden defects that only appear under stress, such as pressure, impact, or vibration, so they aren’t sufficient.
