Supplier declarations for packaging: What your vendors must prove from 2026 onwards

Imagine your audit is the day after tomorrow - and the inspector asks for the PFAS-free declaration for your food packaging. You email your supplier. Two days later: no response, the wrong form, missing values. This is exactly the scenario that FMCG companies face if they haven't yet structured their supplier communication for packaging.

From 12 August 2026, PPWR Declarations of Conformity (DoC) are mandatory for every type of packaging before it can be placed on the EU market. Without complete supplier declarations, you cannot issue a valid DoC. What many procurement and packaging teams overlook: the critical bottleneck often does not sit in their own company - it sits with their suppliers.

This guide flips the perspective. It shows you which specific evidence you need to request from your packaging suppliers, where typical data gaps arise, and how to set up the entire process in a digital, audit-ready way.

Why supplier declarations become critical from 2026

The PPWR (Regulation EU 2025/40) defines clear roles for all actors in the packaging supply chain. Suppliers, manufacturers, importers and distributors each carry specific proof and documentation obligations - and these are tightly interlinked.

Raw material and substrate suppliers may not place packaging on the market themselves. However, from 12 August 2026 they are subject to legal information obligations towards the producer - and must provide key material and conformity data in a structured way. For you as a buyer or packaging owner, this means: the quality of your compliance documentation depends directly on your suppliers' data.

The consequences of data gaps are very tangible:

• No audit-ready DoC -> No marketing of the affected packaging in the EU
• Regulatory inspection -> Missing documentation leads to sanctions
• EPR risks -> Incorrect or missing material data distort EPR reports and EPR fees
• In Germany, violations of the Packaging Act can be punished with fines of up to €200,000 per offence.

Which documents must your suppliers provide?

The following overview shows the core documents you should request from every relevant packaging supplier:

Material declaration and material composition

The material declaration is the foundation of every declaration of conformity for packaging. It describes the exact layer structure of a packaging item, the materials used with their weight fractions, and the composition of all components (container, lid, label, closure).

Pay attention to the following quality criteria:

• Values stated by weight (g or mg/kg) - not only generic material names
• Differentiation by packaging component (e.g. tray vs. film vs. label)
• Declaration of the inks, coatings and varnishes used
• No vague descriptions such as "PE-like material"

PFAS-free declaration

From 12 August 2026, food contact packaging may not exceed PFAS limits of 25 ppb (single value), 250 ppb (sum of identified PFAS) and 50 ppm (total fluorine content). Suppliers that produce films, coatings or paper-based packaging with barrier functions must demonstrate compliance with these limits via test reports or manufacturer self-declarations. You can find more details in our article on PFAS compliance and supplier communication.

Recycled content evidence (PCR certificates)

For plastic packaging, minimum levels of post-consumer recyclate (PCR) will apply from 2030. For sensitive PET food-contact packaging, at least 30% PCR content will be mandatory from 2030, with the quotas increasing further from 2040 onwards. Start collecting data now: begin requesting recycled content certificates from suppliers today. This gives you a reliable planning basis and helps you identify early on which suppliers will not be able to meet these requirements.

Declaration of conformity and technical documentation

Technical documentation and declarations of conformity must be retained for at least 5 years for single-use packaging and for at least 10 years for reusable packaging, and must be provided to authorities upon request. Request structured test reports, drawings and bills of materials - not just the final DoC.

Typical issues in supplier communication

In practice, even in established supply chains, 30-70% of packaging data relevant for PPWR is often missing. The reasons are varied:

Incomplete data deliveries

Suppliers often do not know all relevant parameters. A film supplier, for instance, may not know whether their product is classified as food contact packaging - and therefore does not provide PFAS data. Procurement and packaging teams must therefore define clear requirements in advance and not rely on the supplier's initiative.

Different formats and units

Supplier A provides material data in percentages, supplier B in grams, supplier C uses internal material codes. Without standardised forms, consistent comparison is impossible - and manual harmonisation ties up valuable resources in procurement and quality assurance.

Lack of validation

How do you ensure that the PFAS values declared by a supplier are correct? Without automated consistency checks or cross-referencing with test reports, this remains a matter of trust - not a robust basis for compliance.

Language barriers with international suppliers

Language barriers, especially with suppliers from Asia or Eastern Europe, often lead to misunderstandings: terms such as "recyclable" or "post-consumer recyclate" are interpreted differently. Multilingual, structured forms with clear mandatory fields and dropdown options (instead of free text) help to avoid these issues.

How to set up a structured process

An audit-ready process for supplier declarations does not emerge from sending more emails - it comes from systematic structuring. In six steps, you can build a solid foundation:

How Packa digitises supplier communication

Packa's digital packaging management helps procurement, packaging and QA teams map the entire supplier declaration process digitally, efficiently and in an audit-ready way.

AI-powered specification digitisation

Supplier data is often provided as Excel, PDF or ERP exports - in different structures and formats. Packa automatically reads these documents, harmonises the data and populates a standardised specification profile. AI-supported validation checks consistency and completeness - and a data gap analysis immediately shows which details are missing or inconsistent.

Automated supplier communication

Instead of manual email requests, Packa sends automated, structured requests directly to suppliers - including reminders for missing responses. Suppliers enter their data via a dedicated portal directly into the platform. This eliminates media breaks, reduces errors and significantly accelerates the process.

Smart Matching for supplier selection

Based on complete specification data, Packa's Smart Matching supports you in evaluating and selecting suppliers according to compliance criteria: Which suppliers meet PFAS requirements? Which can prove the required recycled content levels? In this way, compliance requirements become a core decision criterion in procurement. For more on costs and sourcing strategy, see our guide to strategic packaging cost optimisation for procurement teams.

Compliance check and DoC linkage

The supplier data stored in Packa flows directly into automated PPWR compliance checks. Missing or non-compliant values are flagged immediately. The validated data then forms the direct basis for creating the PPWR declaration of conformity - with no duplicate data entry and no media breaks.

Real-world example: A food manufacturer with 1,200 packaging items discovered after the first data gap analysis with Packa that no valid PFAS declaration was available for 68% of items - and recycled content data was completely missing for 41%. Within three months, automated supplier requests and validation checks closed more than 900 data gaps.

Conclusion: Act now - before your supplier becomes a compliance risk

From August 2026, the supplier declaration for packaging will no longer be a formality, but a prerequisite for access to the EU market. Companies that do not obtain the required data from their suppliers in good time and in full risk documentation gaps, market bans and regulatory sanctions.

The good news: with a structured, digital approach, you can make this process not only compliant, but also efficient and scalable. Standardised forms, automated communication and AI-supported validation replace email chaos - and future-proof your packaging data management.

Your next steps:

• Create a complete list of your packaging suppliers and prioritise them by risk profile (food contact, plastics, international suppliers)
• Define standardised mandatory fields for supplier declarations - aligned with PPWR requirements
• Implement digital processes for request, response, validation and archiving
• Link supplier data directly to your PPWR DoC creation
