The declaration of conformity, and who has to write one

Anyone counting as the manufacturer of packaging writes a short document saying the packaging meets the design rules. It is called an EU declaration of conformity. The rules fix what goes in it and set out a model to follow. It has to be kept up to date, and written in a language the country where the packaging is sold asks for. Signing it means taking responsibility for what it says.

Worth knowingNothing delays this one, so it applies from the day the rules started. Where a product needs declarations under several EU rules at once, they can be combined into one document or kept together as a set.
