How long is a PPWR declaration of conformity valid?
The PPWR does not establish a simple principle that a declaration is valid for, for example, one or two years.
The declaration must be kept continuously up to date and updated if the packaging, its characteristics relevant to compliance, or other circumstances on which the declaration was based change. Article 39 of the PPWR lays down that the EU declaration of conformity shall be continuously updated. (EUR-Lex)
It is important not to confuse the validity of the declaration with the document retention period. The manufacturer must keep the technical documentation and the EU declaration of conformity for single-use packaging for 5 years after the packaging has been placed on the market, and for reusable packaging – for 10 years.
