> A technical firm or a laboratory can verify your suppliers' evidence, provided that each document is linked to a specific requirement of the [Packaging and Packaging Waste Regulation (PPWR)](https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX:32025R0040). **No certification is mandatory**: since **12 August 2026**, the manufacturer draws up its **technical documentation** alone, and the authority may request it within **10 days**. No public price list exists for this review, whose workload depends on the number of packaging types and suppliers.

## Key takeaways

- **The PPWR provides for no certificate**: the manufacturer alone proves that its packaging complies.
- Under the PPWR, **suppliers are required to provide** the manufacturer with the evidence it needs.
- **Usable evidence** names the component, the site, the period and the method.
- **Sort the documents by requirement** before chasing suppliers, with one request per gap.

Since **12 August 2026**, [Regulation (EU) 2025/40 on packaging and packaging waste (PPWR)](https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX:32025R0040) requires the manufacturer of a packaging, most often the brand that fills it, to prove its own compliance. The manufacturer applies **internal production control** and draws up **technical documentation**, with no notified body involved and no **PPWR certificate** to obtain. Most of the evidence in this file comes from **its suppliers** of materials, packaging and analyses, as our [PPWR guide](https://projetcelsius.com/en/blog/ppwr-packaging-regulation-guide/) points out.

Having this evidence verified means making sure that it says what the file claims it says, on 4 points: **the component, the site, the period and the method**. The sections below take these points in the order in which a manufacturer meets them, with an example of a document under review.

## What must PPWR technical documentation contain?

The **technical documentation** brings together the documents that prove a packaging type complies with Articles 5 to 12 of the regulation. The manufacturer draws it up **before placing the packaging on the market**, keeps it for **5 years** for single-use packaging and **10 years** for reusable packaging, and hands it to the authorities **within 10 days** of their request (Article 15).

> **What is supplier evidence?** It is a document issued upstream in the chain, by a material producer, a recycler, a converter or a laboratory, that establishes a fact about the packaging or a component: its composition, its content of a substance, its share of recycled material or a measured performance. The manufacturer adds it to its file and remains responsible for it.

### The documents listed in Annex VII

Annex VII describes the procedure, known as module A, and sets the minimum content of the file:

- A general description of the packaging and its intended use, which says which type of packaging each document in the file refers to.
- Design and manufacturing drawings, with the materials of each element, from the body of the packaging to its closure, label and inks.
- The list of standards, common specifications or other technical specifications used to measure or calculate, and the solutions adopted where there is no standard.
- A qualitative description of how the assessments of recyclability, minimisation and reusability were carried out, where they apply.
- Test reports, whether they come from the manufacturer, its suppliers or an external laboratory, with the sample and the method of each test.
- An analysis and assessment of the risks of non-compliance, which say where the file is fragile and how those risks are controlled.

### One file per packaging type

The file is kept **per packaging type**, identified by a type, batch or serial number, and covers **the complete unit**, with its closure and label. The manufacturer keeps procedures so that **series production** stays compliant: a **change of supplier or material grade** may require a new assessment. The [EU declaration of conformity](https://projetcelsius.com/en/blog/ppwr-eu-declaration-of-conformity/) then summarises the file in **8 headings**, following the Annex VIII model. Reusable packaging, kept for **10 years**, also falls under the [reuse rules](https://projetcelsius.com/en/blog/ppwr-reuse-targets-2030/).

### What the file must prove from 2026

Not all requirements apply at the same time. Since 12 August 2026, the file mainly proves compliance with the **substance limits**: **100 mg/kg** for the sum of lead, cadmium, mercury and hexavalent chromium. For packaging in contact with food, the 3 thresholds detailed in our article on [PFAS (per- and polyfluoroalkyl substances) in food packaging](https://projetcelsius.com/en/blog/pfas-food-packaging-ppwr-limits/) are added. Recyclability and the reduction of weight and volume are still judged **under the 1994 rules** and their standards EN 13430 and EN 13428, pending the criteria of the regulation. [Recycled content](https://projetcelsius.com/en/blog/ppwr-recycled-plastic-content-targets/) only applies from **1 January 2030**, as our [PPWR timeline](https://projetcelsius.com/en/blog/ppwr-timeline-deadlines/) points out.

## Do you need a PPWR certificate or a third-party body?

No. The Annex VII procedure is **internal production control**: the manufacturer ensures and declares, on its sole responsibility, that the packaging meets the requirements, **with no notified body** and no certificate to obtain. A document titled "PPWR certificate" therefore has **no regulatory value of its own**. It is worth what the evidence it gathers is worth.

### What the Commission says

In its [guidance document of 10 June 2026](https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX:52026XC03084), the Commission specifies that the assessment may be carried out by the manufacturer or by a person acting on its behalf, for example a laboratory or a certification scheme. The declaration, for its part, relies on documentation **provided by suppliers**. Using such a person remains **a choice**. No harmonised standard has yet been published under the regulation. The standards of the former directive now serve only as guidance, except **standard EN 13428** on source reduction, which gives a presumption of conformity **until the end of 2029** according to the Commission's [FAQ](https://environment.ec.europa.eu/publications/faq-packaging-and-packaging-waste-regulation-ppwr_en).

### Where a third party intervenes or will intervene

For **recycled content**, the calculation and verification method that the Commission must adopt by 31 December 2026 at the latest may include an obligation to carry out **independent third-party audits** (Article 7). The Commission's [call for evidence of 14 August 2026](https://ec.europa.eu/info/law/better-regulation/have-your-say/initiatives/18753-Plastic-packaging-harmonisation-of-rules-for-calculating-and-verifying-recycled-content-in-plastic-packaging_en) mentions a traceability chain and third-party audits where necessary, **without naming any certification scheme**. For recycled plastic in contact with food, another text, [Regulation (EU) 2022/1616](https://eur-lex.europa.eu/eli/reg/2022/1616/oj), already requires **third-party certification** of the pre-processing step of recycling.

### What the authority may request

In France, the competent authority is the **Directorate-General for Risk Prevention** (DGPR), according to [French customs](https://www.douane.gouv.fr/en/node/18948). Missing, incomplete or erroneous technical documentation is a **formal non-compliance** (Article 62), which, if it persists, may lead to a ban, withdrawal or recall of the packaging. National penalties must be set **by 12 February 2027 at the latest**. These rules come on top of those of [extended producer responsibility (EPR) for professional (B2B) packaging](https://projetcelsius.com/en/blog/france-epr-professional-packaging-2027/).

> There is no PPWR certificate, only a file that proves compliance document by document.

## Which evidence should you request from suppliers?

Article 16 **requires suppliers** of packaging and packaging materials to give the manufacturer all the information and documentation it needs, in a language it understands, on paper or in electronic form. The text sets **no deadline**. The Commission's FAQ infers that a supplier **cannot refuse**, and asks for **reasonable efforts** for stocks whose supplier has disappeared: asking the former supplier, or carrying out one's own assessments.

### The 3 documents that carry the proof

In most files, 3 types of document carry most of the proof:

- The supplier's declaration of composition, which names the exact material and grade of each element and states the presence and content of regulated substances.
- The recycled content attestation, accompanied by the traceability certificate of the site that produced the material, for the delivery period concerned.
- A laboratory test report, which identifies the sample, the method, the limit of quantification and the result, for example for heavy metals or total fluorine.

For packaging in contact with a sensitive product, **the documents specific to sensitive-contact products** (food, cosmetics, medicines, medical devices) are added, which Article 16 expressly lists among the documents to be supplied to the manufacturer. The same document may serve 2 requirements, **provided it refers to the same component** and the same period.

### The case of PFAS

For PFAS, the guidance document recommends 3 steps: measure **total fluorine**; above **50 mg/kg**, check by pyrolysis and chromatography whether that fluorine is organic; then check the thresholds of 25 and 250 µg/kg with a TOP (total oxidisable precursor) assay. According to the Commission, a sample that complies at the first step complies at the next 2 as well: **total fluorine below 50 mg/kg is enough**.

Above that threshold, Article 5 requires the substance's manufacturer, importer or downstream user to provide evidence **on request**, so that the packaging manufacturer can draw up its file. The thresholds and their logic are detailed in our article on the [PFAS ban](https://projetcelsius.com/en/blog/pfas-ban-france-eu/), and the claims that can no longer be made on packaging in our [list of banned environmental claims](https://projetcelsius.com/en/blog/banned-environmental-claims-eu/).

## How do you choose who verifies the file?

The regulation reserves the review to no profession. The non-negotiable criterion is the **ability to link a document to a requirement**. A good reviewer knows that a recycling certificate does not prove a heavy metal content, that a food contact declaration says nothing about recyclability, and that a test report applies to one sample, not to a range. The reviewer **has not produced the evidence they review**, as with a [critical review of a life cycle assessment (LCA) (in French)](https://projetcelsius.com/blog/revue-critique-acv-choisir-expert-independant/) *(in French)*.

### Questions to ask

Before signing, 4 questions are enough to compare 2 offers:

- Which requirements of the regulation does the review cover, article by article, and which remain out of scope for lack of a published implementing act?
- Did the provider take part in designing the packaging or in producing any of the evidence it will review?
- What does the deliverable contain: a list of gaps per document, with the text concerned and the document to request from each supplier?
- Who writes to the suppliers for the additional collection, and how are the new documents incorporated into the file and the risk analysis?

### Warning signs

Some offers promise more than the regulation makes it possible to deliver:

- A "PPWR certificate" or a "conformity label" issued at the end of the review, whereas the regulation provides for neither.
- Validation of an entire range on the basis of a single sample, or of a single supplier declaration valid for all sites.
- Guaranteed compliance with the 2030 requirements, whereas the acts that will set the recycled content method and the recyclability classes have not been published.

The same reflexes apply to an [audit of environmental claims](https://projetcelsius.com/en/blog/empco-green-claims-audit/), which also links **each message to its evidence**, to having a [carbon footprint assessment verified by a third party (in French)](https://projetcelsius.com/blog/bilan-carbone-interne-verification-tiers/) *(in French)*, or to choosing a [verifier for an FDES (in French)](https://projetcelsius.com/blog/fdes-pep-choisir-verificateur-habilite/) *(in French)* (the French format of environmental product declaration for construction products).

## How does a documentary review work?

A review of supplier evidence follows 4 steps:

- An inventory of the packaging types and their components, with, for each, the supplier, the production site and the requirements that apply on the date of placing on the market.
- A document-by-document review, checking that each piece of evidence refers to the right component, the right site, the right period and the right method.
- Additional collection from suppliers, with a precise request for each gap rather than a general questionnaire sent to the whole chain.
- An update of the file and of the non-compliance risk analysis, then of the EU declaration of conformity if a document changes.

### One document reviewed, line by line

A review line links **a document to a requirement** and says **what is missing** for it to prove anything. The example below is built for the article: 5 gaps that recur in supplier evidence, each with the line as it arrives and as it proves.

### What the gaps have in common

In these 5 cases, **the document exists**, but it does not refer exactly to the packaging in the file: another site, another grade, another period, a sample with no reference. A precise request, gap by gap, generally obtains the right version **from the same supplier**, whereas a general questionnaire sent out to the whole chain brings back the same generic declarations.

### Timing and price

**No public price list** exists for a review of supplier evidence. The workload depends on the **number of packaging types**, the number of suppliers and the quality of the documents already gathered. To give an idea, in a constructed example: a PET (polyethylene terephthalate) bottle with its cap, label and ink has **4 elements**. If it touches food, heavy metals and PFAS alone already give **8 review lines**, each backed by a document from a named supplier. The **additional collection**, which follows the pace of supplier replies, generally sets the real timing. The **10-day** deadline for replying to an authority therefore assumes a file that is already complete.

## What should you prepare before the review?

A review goes faster when the manufacturer has already **sorted its documents** by packaging type and by requirement. The items to gather:

- The list of packaging types placed on the market since 12 August 2026, with their type or batch numbers and the countries of sale.
- The bill of materials of each packaging, from the body to the closure, label, ink and adhesive, with the supplier and production site of each.
- The documents already received, sorted by requirement, with their issue date, validity period and the component they refer to.
- The purchase specifications, to check that they require suppliers to pass on their evidence and to report any change of material or site.
- The name of the person who signs the EU declaration of conformity, and of the person who answers the authorities within the 10-day deadline.

For a micro-enterprise that buys its packaging, the packaging supplier, if established in the same Member State, **becomes the manufacturer** within the meaning of the regulation (Article 3), a case covered in [our article for micro-enterprises](https://projetcelsius.com/en/blog/ppwr-small-businesses-obligations/). A [seller established outside France](https://projetcelsius.com/en/blog/french-epr-authorised-representative/) has other obligations, and an importer checks that the foreign manufacturer has drawn up the technical documentation and keeps it available for **5 or 10 years**. What falls to each role is detailed in our test [am I affected by the PPWR](https://projetcelsius.com/en/blog/ppwr-who-is-affected/).

At Projet Celsius, a useful review starts with the **requirements that already apply**, substances and PFAS, before those of 2030 whose methods are not published. We recommend asking each supplier for **one document per requirement and per site**, rather than a global declaration, and keeping a record of each request, which will show the effort made if a document is missing. Our [PPWR support](https://projetcelsius.com/en/services/ppwr-compliance) organises this review and the collection that follows it, and our guides on [packaging eco-design](https://projetcelsius.com/en/blog/packaging-eco-design-ppwr-2030/) prepare the 2030 requirements.

## Key takeaways

- **The manufacturer alone proves compliance** of each packaging type, through its technical documentation and with no certificate to obtain.
- **Suppliers must provide** the manufacturer with the necessary information and documents, and cannot refuse according to the Commission.
- **Usable evidence** names the component, the site, the period and the method; a generic declaration proves nothing.
- **Since 12 August 2026**, the file mainly covers substances and PFAS; recycled content is added in 2030, together with the new recyclability and minimum weight criteria.

The document that summarises this file, the EU declaration of conformity, is covered in our article on [what it must contain](https://projetcelsius.com/en/blog/ppwr-eu-declaration-of-conformity/), and the packaging that the regulation bans in our [list of banned packaging](https://projetcelsius.com/en/blog/ppwr-banned-packaging-formats/).

## Frequently asked questions

### Is there a PPWR certificate?

No. Regulation (EU) 2025/40 provides for no certificate and no notified body for packaging: the manufacturer applies an internal production control procedure (Annex VII), draws up technical documentation and signs an EU declaration of conformity. A document called a "PPWR certificate" has no regulatory value of its own; it is worth what the evidence it gathers is worth.

### Who must draw up the PPWR technical documentation?

The manufacturer of the packaging, which in general means the company whose brand appears on the packaging or which had it designed. It may entrust the assessment to a laboratory or a service provider, but it remains solely responsible. The authorised representative it may appoint cannot be tasked with drawing up the technical documentation. Suppliers, for their part, must provide it with the necessary information.

### How long must PPWR technical documentation be kept?

5 years from placing on the market for single-use packaging, and 10 years for reusable packaging. The same period applies to the EU declaration of conformity. At the request of a market surveillance authority, the manufacturer provides these documents in electronic form, and on paper if the authority asks, within 10 days.

### Can a supplier refuse to provide its PPWR data?

Not according to the Commission. Article 16 of the regulation requires suppliers of packaging and packaging materials to give the manufacturer all the information and documentation needed, without setting a deadline. For packaging in stock whose supplier has disappeared, the Commission's FAQ asks for reasonable efforts: approaching the former supplier or carrying out one's own assessments.

### Do you need a laboratory to prove PPWR compliance?

Not always, but test reports are part of the technical documentation, and some requirements are hard to prove without them. The heavy metal limits (100 mg/kg) and the PFAS thresholds for food packaging are generally established by analysis. The report must identify the sample, the method and a limit of quantification below the threshold to be demonstrated.

### What is the difference between technical documentation and a PPWR declaration of conformity?

The technical documentation is the evidence file: description of the packaging, materials, standards used, assessments, test reports and risk analysis. The EU declaration of conformity is the document of a few headings, signed by the manufacturer, that asserts compliance on the basis of that file. The declaration is presented; the documentation is kept available to the authorities.
