Basically it is required that the responsible supplier can produce documentation for every single packaged product. However, there is a certain flexibility to put the products in groups and use the same documentation for more than one product. If the only differences between products are minor things like labelling, flavouring and the like it is possible to organize and use the same documentation. Such product groups are not allowed but it is possible to organize data in such a way, that it works in practice. It is impossible to define clear limits regarding this possibility, so it is left to the individual company to decide whether the documentation is sufficient. Regardless of this any official authority can demand the information for each individual packaged product.
