Parallel distribution - To cover or not to cover original batch and expiry

Dears,

Are parallell distributors obliged to not cover the original batch and expiry of the source product? Where can more information about this be found on the EMA website?

Kind regards,
Mikael

For the requirements on the batch numbers for the parallel-traded products, please refer to Chapter 5 Question 5 ‘What are the requirements for batch numbers appearing on the packaging of medicinal products subject to parallel trade?’ of the Guidance on good manufacturing practice and good distribution practice: questions and answers.
