Why can't a shipper substitute a non-specification container for hazardous materials even if it seems strong enough?

Pick an answer

1. Container specification only matters for international shipments, not domestic ones within the same state or region, even though the manual describes a different procedure
2. Substitution is fine as long as the container is new
3. Any container rated for heavy loads is automatically acceptable
4. Only containers tested and approved for that specific hazard are certified to perform safely under transportation conditions
