When does the Grandfather clause for performance-oriented packaging apply?

The Grandfather clause for performance-oriented packaging is significant in the context of hazardous materials regulations, particularly regarding how certain containers can be utilized for shipping. This clause essentially allows for packaging that was compliant with earlier regulations to continue being used, despite changes introduced in later regulations. The correct date for the grandfathering of performance-oriented packaging is January 1, 1990. This date marks the transition when new performance-oriented packaging requirements were established, permitting packages that met the standards in effect prior to that date to still be considered compliant.

The rationale behind this cutoff is to provide a smooth transition for manufacturers and shippers, allowing them to use existing packaging rather than requiring immediate compliance with new standards, which could entail significant costs and disruptions. Understanding this date is crucial for anyone involved in the handling and shipping of hazardous materials, as it directly impacts the compliance and safety protocols required in their operations.
