Overview

The packaging unit is the subject of the Declaration of Conformity. On the Packaging units page (sidebar → Packaging units, /packaging) you see four distribution tiles at the top (role distribution, packaging type, data completeness, obligation status) and below them the searchable, filterable table of your units.

You create a new unit via New packaging. This opens the create dialog with the same form used for editing.

​
The form

The form has two sections: Master data and Classification.

​
”Master data” section

You can leave the internal reference blank when creating a unit. Polygon One then assigns the next free reference for your company automatically — PU-1, PU-2, PU-3 and so on. References you enter yourself are never changed or renamed. This applies to every way a unit comes into being: this form, the dialogs that create units from an article or component selection, the CSV/Excel import and the API.When editing an existing unit the reference stays required — it cannot be blanked afterwards.

​
”Classification” section

The recyclability grade is a declared value. The EU assessment methodology under Art. 6 only arrives via delegated acts (expected 2028). Polygon One does not assess recyclability automatically — it only stores the grade you enter.

​
Supplier, producer (EPR) and Art. 21

A bordered box at the end of the section contains:
  • Supplier — the operator assigned to this unit. For an importer or authorised representative this upstream operator provides the Declaration of Conformity; for a distributor it is the upstream operator whose producer registration and marking are checked (and who may provide the declaration voluntarily on request).
  • Producer (EPR) — a switch (only for manufacturer, importer, distributor). It marks that you are the first to place this unit on the market in a Member State’s territory (producer within the meaning of Art. 3(15)) and therefore carry extended producer responsibility — registration, reporting, fees. This is not the same role as the manufacturer who signs the Declaration of Conformity.
  • Art. 21 switches (only for importer/distributor): Placed under own brand and Modified affecting conformity. If either applies, you assume the manufacturer’s obligations — you then issue the Declaration of Conformity yourself.

​
The detail page

After creating, the detail page opens with five tabs:
  • Overview — the packaging data (the same form) for editing.
  • Components — this unit’s bill of materials (count in brackets).
  • Obligations — which PPWR obligations apply to this unit and their status.
  • Documents — Declaration of Conformity, technical documentation and attached evidence.
  • Articles — the articles linked to this unit.

​
Managing components (bill of materials)

In the Components (bill of materials) tab you build the composition of the unit:
1

Link an existing component

Under Link existing component, choose a component, enter the quantity and click Link.
2

Create a new component

Via New component you open the component form; the new component is linked directly to this unit.
3

Change quantity or unlink

Adjust the quantity per row directly. Use the trash icon to unlink a component from the unit.
4

Edit data

Expand a row to edit the component’s data inline. The Data completeness badge per row shows what is still missing.

Details on the component fields (heavy metals, PFAS, recycled content) are in Components.

​
Unit obligations

The Obligations tab shows, per packaging unit, the applicable PPWR obligations and their status. Obligations that only enter into force in 2028/2030 are marked as “not yet in force” and are never flagged as outstanding. How these obligations derive from the role is described in the obligations catalogue.

Create a Declaration of Conformity

Once a unit is ready, issue the declaration in the “Documents” tab.
