Model, batch or item?
Pick it once, live with it
A product passport can describe a whole model, a single production batch, or one individual item. The three options cost very different amounts to print and manage - and once your product is on the market, the level has to stay the same. Eight questions, one recommendation.
Why this choice is worth ten minutes
Going finer than you need means printing a unique code on every single unit, keeping a record per unit and paying for all of it forever. Going coarser than you need means that when something goes wrong, you cannot tell which production run it came from.
The rules for your product group may already fix the level - in that case the delegated act wins. This tool is for the space the rules leave open, which is most of it today. If you want the full picture first, read the guide or build a demo passport.
