With regard to packaging materials, Q7A does not make a distinction between inner and outer containers. If you have written procedures for the inner containers that actually come into contact with the API, do you also need written procedures for the outer containers, such as fiberboard boxes that do not actually contact the API? An example of the inner container might be glass jar or vial.

9.2 states that containers should not be additive beyond the specified limits. This imputes the need to evaluate packaging for interaction with the API. On the other hand, that additive of packaging implied is not a concern so long as the API is not altered beyond its specification. Please clarify how an API manufacturer might justify not evaluation product/packaging interactions.
