The declaration window is short,
so the data work starts in November.
French household packaging is declared once a year, for the previous calendar year, in a window that opens on 1 January and closes at the end of February. The work that makes that window survivable happens before it opens.

Timing depends on document completeness and independent registry and scheme review
The outcome
A declaration that can be explained a year later
- Volume, product family and packaging data reconciled before the window opens
- Declaration mode and its thresholds documented with the scale used
- Filed declaration, invoice and payment kept as dated evidence
The eco-organisation calculates and invoices the contribution on its published scale
The calendar comes from the scheme, not from us
Under the published 2026 Léko terms, household packaging and papers are declared between 1 January and the end of February for the previous year; an annual contribution of €10,000 or less is invoiced annually by 31 March and larger amounts are invoiced quarterly. Citeo publishes its own scale and terms for the same stream, so the applicable calendar follows the eco-organisation actually joined.

Why an annual duty fails at the last minute
The data is assembled in February
Order data, product families and packaging specifications take time to reconcile. A late start turns an annual duty into an estimate nobody can defend.
The declaration mode is chosen by accident
Simplified and detailed modes have published thresholds. Crossing one changes the data you must be able to produce.
The invoice is treated as our fee
The eco-organisation invoices the member on its own scale. Our fee is separate, and an unpaid contribution is a scheme matter that reaches the producer.
Included in the written scope.
- Annual data request and reconciliation plan from November
- Product family and shipment-packaging mapping
- Declaration-mode review against the published thresholds
- Filing coordination inside the published window
- Invoice tracking and payment reminders
- Retention of filings, invoices and receipts by year

Frequently asked
When exactly is the declaration due?
The published window runs from 1 January to the end of February for the previous calendar year. The eco-organisation joined confirms the exact portal and deadline each year.
What if we joined mid-year?
The first declaration still covers the period during which products were placed on the market. What matters is that the data exists for that period, which is why the mandate perimeter records it.
Do you pay the contribution for us?
The contribution is invoiced by the eco-organisation on its own scale. Our service fee is separate and includes no percentage of it.
Can eco-modulation change the amount?
Yes. Bonuses and penalties apply on published criteria. They are reviewed with the client and never applied automatically to an estimate.
