When a procurement manager in the food‑packaging arena orders a new tray, a reusable cup or a bulk container, the product’s safety and marketability depend on more than the price tag. In the European Union, many packaging items must carry the CE mark, which tells the buyer that the product complies with the applicable EU legislation. The paperwork behind that mark – the Declaration of Conformity, the technical file and supporting test reports – is the backbone of a trustworthy supply chain. This guide explains what you should ask suppliers for, how to verify those documents, the extra layers of risk when you source from outside the EU, and the logistical details that keep delivery on schedule.
What Information Must Be Stated in Your Purchase Specification?
Before you even contact a supplier, translate the regulatory requirements into a clear specification. The most common CE‑relevant directives for food‑related packaging are:
- Regulation (EU) No 1935/2004 on materials and articles intended to come into contact with food.
- Regulation (EU) No 10/2011, which sets specific limits for plastic materials that contact food.
- Regulation (EU) No 2023/2006 on the packaging and packaging waste (the “Packaging Waste Directive”).
From these regulations you can extract the following mandatory fields for your spec sheet:
- Intended use – hot fill, microwave, freezer, single‑use, reusable, etc.
- Material composition – polymer type, additives, barrier layers, any recycled content.
- Compliance route – full CE marking with a Declaration of Conformity, or exemption under a specific clause (e.g., custom‑made articles).
- Relevant harmonised standards – for plastics, EN 13432 (compostability) or EN 15593 (paper and board), for metal, EN 1672‑2 (food‑contact metals).
- Testing requirements – migration testing, overall migration limits, specific migration for substances of concern (e.g., BPA, phthalates).
- Documentation deliverables – signed Declaration of Conformity, complete technical file, test certificates, and a copy of the CE‑marking affixed to the product or its packaging.
By turning the legal language into a concise list, you give suppliers a single reference point and reduce the risk of missing a clause later in the process.
How to Validate Supplier Documentation
Even a perfect specification cannot guarantee compliance if the supplier’s paperwork is incomplete or fabricated. A layered verification approach works best.
1. Request the Full Declaration of Conformity (DoC)
The DoC must contain the supplier’s name, product identification, the list of applied directives, reference to the harmonised standards used, and the signature of an authorised person. Check that the DoC is dated within the last 12 months; an older document may indicate that the product design has changed without a new assessment.
2. Examine the Technical File
The technical file is the “black box” that regulators would inspect. It should include:
- Design drawings or CAD files showing dimensions, tolerances and material layers.
- Manufacturing process description – extrusion, injection moulding, lamination, etc.
- Risk assessment notes – especially for food‑contact articles, a hazard analysis covering migration, leaching and microbiological risks.
- Test reports from an accredited laboratory (e.g., ISO/IEC 17025 accredited). Look for the lab’s accreditation number and the test method reference (e.g., EN 1186‑1 for overall migration).
- Instructions for use and labelling – the CE symbol, any required warnings, and traceability codes.
Ask the supplier to provide the file in an editable format (e.g., PDF with searchable text) so you can run a quick keyword check for the relevant directives and standards.
3. Conduct a Third‑Party Audit or On‑Site Visit
If the supplier is critical to your product line, a one‑day audit can confirm that the documented processes match reality. Key audit points include:
- Verification that the production line used for the sampled batch matches the line described in the technical file.
- Review of calibration records for testing equipment (e.g., migration test chambers).
- Observation of traceability – batch numbers, material certificates, and the handling of non‑conforming items.
When an on‑site audit is not feasible (e.g., a distant Asian factory), a remote audit using video walkthroughs and screen‑share of quality management software can be an acceptable alternative, provided the supplier’s quality system is ISO 9001 certified.
4. Run a Sample Order Through Your Own Lab
Even with a perfect DoC, a sample test can catch hidden issues such as contamination from a new supplier’s cleaning agent or a change in polymer melt temperature that alters migration levels. Keep a small reserve of budget for an in‑house or contracted test on the first shipment.
Overseas Sourcing: Specific Risks and How to Mitigate Them
Many food‑packaging manufacturers operate in Asia, Eastern Europe or North Africa. While cost advantages are real, they come with compliance challenges.
Regulatory Interpretation Gaps
Some non‑EU manufacturers are unfamiliar with the nuances of EU food‑contact legislation. They may rely on “general safety” certificates that do not address migration limits. To bridge this gap, provide a short “EU compliance brief” that outlines the exact tests required, the acceptance criteria, and the reference standards. Request a written acknowledgement that the supplier has read and will follow the brief.
Document Authenticity
In jurisdictions with less stringent enforcement, forged test certificates are a known problem. Counter‑check the lab accreditation number against the national accreditation body (e.g., UKAS for the United Kingdom, CNAS for China). If a certificate lists a lab you cannot verify, request an additional test from a lab you know is accredited in the EU.
Supply Chain Visibility
Complex subcontractor networks can obscure the true source of raw material. For example, a polymer granulate may be sourced from a third party that does not hold its own CE‑type certification. Include a clause in the purchase contract that obliges the primary supplier to disclose all sub‑suppliers of regulated material and to provide their respective certificates.
Customs and Regulatory Delays
Even with correct documentation, customs can hold shipments if the paperwork does not match the physical goods. Use the Incoterm DAP (Delivered at Place) when you want the supplier to handle import clearance, or DDP (Delivered Duty Paid) if you prefer them to bear the risk of any regulatory hold‑up. Align the incoterm choice with your internal logistics capabilities and risk appetite.
Incoterms, Lead Times and Planning for CE‑Marked Packaging
Choosing the right Incoterm influences not only cost but also who is responsible for ensuring the CE documentation travels with the goods.
- EXW (Ex Works) – the buyer takes full responsibility from the supplier’s warehouse. You must arrange your own freight forwarder and ensure they request the DoC and technical file before loading.
- FCA (Free Carrier) – the supplier delivers the goods, cleared for export, to a carrier you name. The supplier remains responsible for the export paperwork, including the CE marking evidence.
- CPT (Carriage Paid To) – the supplier pays the main carriage, but risk transfers at the first carrier. Useful when you trust the carrier to verify that the CE documentation is on board.
- DAP (Delivered at Place) – the supplier bears all costs and risks up to your warehouse, including customs clearance. Ideal for high‑value, low‑volume packaging where you want the supplier to manage any CE‑related customs queries.
- DDP (Delivered Duty Paid) – the supplier takes on the maximum responsibility, including duties, taxes and any regulatory inspections. This term is the safest for buyers unfamiliar with foreign customs procedures.
Lead times for CE‑marked packaging depend on three variables:
- Design finalisation – from a frozen design to a signed DoC typically takes 2‑4 weeks, assuming the supplier already has the relevant test methods in‑house.
- Testing cycle – laboratory analysis for migration can be 5‑10 working days per batch, plus any repeat testing if the first results are borderline.
- Logistics – sea freight from East Asia adds 30‑45 days, air freight 5‑7 days, plus customs clearance (usually 2‑3 days if documentation is complete).
When you combine these stages, a realistic total lead time for a new CE‑marked product sourced from China is 8‑10 weeks. Build a buffer of at least 10 % of the total time to accommodate unexpected re‑testing or customs holds.
Three Actionable Tips for Procurement Success
- Embed a “Compliance Clause” in every contract. State that the supplier must provide a valid DoC and full technical file before each shipment, and that any missing or non‑conforming documentation will trigger a payment hold.
- Use a “Document Checklist” as a gatekeeper. Before authorising production, require the supplier to tick off a checklist that includes DoC, test reports, lab accreditation numbers, sub‑supplier disclosures and a signed statement of conformity to the specific EU regulations you have cited.
- Implement a “First‑Lot Verification” process. Treat the initial delivery as a pilot batch: have your QA team conduct an independent migration test and cross‑check the batch numbers against the technical file. Only after this step do you release the supplier for regular volume orders.
FAQ
What is the difference between a CE mark and a Declaration of Conformity? The CE mark is a visual symbol placed on the product, indicating that it meets EU requirements. The Declaration of Conformity is a written statement from the manufacturer that specifies which directives apply and which standards have been used to achieve compliance.
Can a custom‑made packaging item be exempt from CE marking? Yes, if the item is made to a specific customer order and does not fall under a mandatory CE‑marked product category, the manufacturer may issue a “non‑standard” declaration, but the buyer should still request a technical file to prove safety.
How do I verify that a laboratory’s test report is genuine? Check the lab’s accreditation number against the national accreditation body (e.g., UKAS, CNAS). The report should list the test method (e.g., EN 1186‑1), the date of analysis, the sample identification and the analyst’s signature.
What should I do if a supplier cannot provide the original CE documentation? Request a copy of the original documents and a signed statement confirming their authenticity. If the supplier cannot produce the original, consider an alternative supplier or require an independent third‑party assessment before proceeding.
Is it safe to rely solely on a supplier’s ISO 9001 certification for CE compliance? ISO 9001 demonstrates a quality management system but does not guarantee that specific CE‑related tests have been performed. You still need the Declaration of Conformity, technical file and relevant test certificates.
