France EPR IDU (UIN): What Does It Mean, and What Must You Do After Getting the Number?

Getting a French EPR identification number is not the end of the compliance process.

For businesses selling products in France, the EPR identification number is often referred to in English as a UIN. In French legislation and official ADEME guidance, however, the formal term is IDU — Identifiant Unique.

An IDU provides evidence that a producer is registered in France's EPR reporting system, SYDEREP, for a particular EPR stream. But it should not be treated as a one-off certificate that permanently completes all EPR obligations.

Businesses must still maintain the relevant EPR arrangements, provide required data, keep their registration information accurate and comply with the rules applicable to each product stream.

What exactly is a French EPR IDU?

Under Article L.541-10-13 of the French Environmental Code, producers subject to Extended Producer Responsibility must register with the competent authority and receive a unique identifier.

ADEME administers the French EPR registration system through SYDEREP.

The important point is that an IDU relates to one producer and one EPR stream.

This means a business can have several different IDUs where its products fall within several French EPR schemes. ADEME specifically states that a producer should have as many IDUs as there are relevant EPR streams, including the applicable packaging stream.

Therefore, having one valid IDU should never automatically be interpreted as meaning that every product sold by the company is covered.

One IDU does not necessarily cover all your products

This is particularly important for ecommerce businesses.

A seller may need to consider several EPR streams depending on what it places on the French market. For example, a product may need to be assessed separately for the product itself, its batteries, its electrical or electronic characteristics and its packaging.

The exact EPR classification depends on the product and the scope rules of the relevant French REP (Responsabilité Élargie du Producteur) stream.

Before submitting an IDU to a marketplace or displaying it on a website, businesses should therefore confirm that the number corresponds to the correct:

• legal entity;

• EPR stream;

• product scope;

• eco-organisation or approved individual system; and

• current business activity.

What must you do after receiving your French EPR IDU?

1. Maintain your eco-organisation membership or individual system

For most businesses, compliance is managed through an approved eco-organisation.

In a collective system, the relevant eco-organisation registers the producer in SYDEREP and communicates the IDU to the producer. Alternatively, a producer can establish an approved individual system where the applicable regulatory conditions are met.

Obtaining the IDU does not replace the continuing obligations connected with that system.

Where an eco-organisation is used, contribution rates, reporting procedures and other administrative requirements depend on the relevant EPR stream and the eco-organisation concerned. Businesses should therefore avoid assuming that there is one universal French EPR fee or one reporting timetable covering every category.

2. Report the required data every year

French environmental law provides for annual reporting for each relevant EPR product category.

The information required under Article L.541-10-13 can include evidence of membership in an eco-organisation or establishment of an individual system, information about products placed on the market, information concerning the management of waste arising from those products and other data used to monitor waste-prevention and waste-management objectives.

The law allows producers to make these submissions through their eco-organisation.

In practice, this means that businesses using an eco-organisation will generally need to provide the organisation with the required sales or placing-on-the-market data so that the appropriate EPR declarations can be completed.

The precise data fields and submission timetable can vary according to the EPR stream and eco-organisation, so businesses should follow the requirements applicable to their specific registration rather than relying on a generic deadline found online.

3. Display your IDU in the required places

An often-overlooked requirement is that simply possessing an IDU is not enough.

Article R.541-173 of the French Environmental Code requires a producer to include its IDU in its general terms and conditions of sale or, where it does not have such terms, in another contractual document communicated to the buyer.

A producer with a website must also communicate the IDU on its website in accordance with the applicable legal information requirements.

In addition, Article L.541-10-10 provides that the seller of an EPR-covered product must, when requested by the buyer, communicate the IDU of the producer fulfilling the EPR obligations for that product.

4. Make sure the IDU submitted to marketplaces matches the correct EPR stream

French law also places responsibilities on online marketplaces and other electronic interfaces facilitating sales by third-party sellers.

Under Article L.541-10-9, an electronic marketplace may itself become responsible for EPR obligations unless it holds evidence that the third-party seller has already fulfilled the relevant obligations.

For this purpose, possession of an IDU for the products concerned is treated by French law as evidence of the third party's compliance with those obligations.

This helps explain why marketplaces request EPR registration numbers from sellers.

However, sellers should still make sure that they are providing the IDU for the correct legal entity and the correct EPR stream. A packaging IDU, for example, should not simply be assumed to satisfy an unrelated product EPR stream.

5. Review your registration when your business changes

Because an IDU is connected to a particular producer and EPR stream, changes to a business can affect its EPR position.

Businesses should review their French EPR registrations when there are material changes such as a change of legal entity, product range, relevant EPR streams or the eco-organisation responsible for compliance.

The objective should be to ensure that the information recorded in the EPR system continues to reflect the producer actually placing the relevant products on the French market.

Important 2026 change for businesses outside France

There is an important new requirement that cross-border sellers should not overlook.

Since 10 July 2026, a person not established in France who is subject to French EPR obligations under Articles L.541-10 or L.541-10-9 must, in principle, appoint by written mandate a natural or legal person established in France to act as its representative for those EPR obligations.

The representative assumes the EPR obligations covered by the mandate.

The legislation also contains an exception where, for the relevant products, a France-established electronic marketplace or similar operator covered by Article L.541-10-9 itself fulfils the EPR obligations.

This change is particularly relevant to overseas ecommerce sellers that previously focused only on obtaining an IDU.

Non-French businesses should therefore review both their existing IDUs and their representative arrangements rather than assuming that a previously obtained registration number, by itself, addresses the new requirement.

Can an IDU be withdrawn?

Yes.

ADEME explains that an IDU is not necessarily permanent.

For producers using a collective system, removal of an IDU can be initiated by the relevant eco-organisation. For an approved individual system, removal may occur following cessation of activity or the end of the system's approval.

This is another reason why businesses should not treat an old IDU document or marketplace record as permanent evidence that the underlying EPR arrangements are still current.

ADEME publishes information on producers registered in SYDEREP, allowing businesses and other parties to verify registration information.

Are there penalties for incorrect French EPR registration?

French EPR requirements are enforceable and should not be treated purely as marketplace account requirements.

Article L.541-9-5 of the French Environmental Code provides for administrative sanctions for certain breaches of the EPR rules.

Among other enforcement measures, an additional administrative fine of up to €30,000 may be imposed in specified circumstances where a person subject to EPR fails to register in the relevant register, fails to provide the required information, provides incorrect data or fails to display the IDU on the required materials.

Other administrative penalties can also apply depending on the nature and scale of the infringement.

The exact consequences depend on the facts of the case, so the €30,000 figure should not be presented as an automatic fine for every EPR mistake.

So, what does an IDU actually prove?

The safest way to understand the French IDU is as an EPR registration identifier for a particular producer and a particular EPR stream.

It is important evidence of registration, and French law gives it an important role in demonstrating compliance to marketplaces.

But it does not mean that all future obligations disappear.

Ongoing compliance can still involve maintaining the appropriate eco-organisation or individual-system arrangement, submitting annual data, meeting contribution requirements, displaying the IDU correctly, keeping registration information accurate and complying with any additional obligations applicable to the relevant product category.

Frequently Asked Questions

Is one French IDU enough for my entire business?

Not necessarily. ADEME issues an IDU for a producer in relation to a particular EPR stream. If your products fall within multiple EPR streams, you may require multiple IDUs.

Do I still need to make declarations after receiving the IDU?

Yes. French law provides for annual reporting of information relating to the relevant EPR categories. Producers using an eco-organisation can generally provide the required information through that organisation.

Does the IDU have to appear on my website?

Where the producer has a website, Article R.541-173 requires the IDU to be communicated on the website in accordance with the applicable legal-information rules. It must also appear in the producer's general terms of sale or, where those do not exist, another contractual document communicated to the buyer.

Do overseas sellers now need a French EPR representative?

Since 10 July 2026, French law requires a person not established in France who is subject to the relevant French EPR obligations to appoint a France-established representative by written mandate, subject to the exception set out in Article L.541-10-9-1.

Is there one annual EPR declaration deadline for every French EPR category?

No single deadline should be assumed for every situation. The legal framework requires annual reporting, while practical submission schedules and data requirements depend on the relevant EPR stream and, where applicable, the eco-organisation involved.
