Assess a packaging supplier’s PPWR support by asking them to work through one real packaging specification with you. The useful connection is between what the rules require, what your box is made from, the evidence supporting it and how those choices are maintained in production. For brands sourcing custom paper packaging from China for non-food products sold in the EU, these twelve questions make that support easier to compare.

Start with a current sample or proposed design, your product details, EU destinations and intended market date. Ask for examples of documents or methods where useful. For a new construction, the supplier may need to define a development step before packaging-specific evidence is available; the quality of that proposal is part of what you are assessing.

1. Which parts of our packaging and supply route are you assessing?

Good support starts by defining the job. A supplier should ask what the product is, how it will be packed and transported, where it will be sold, whether packaging is supplied empty or filled, and which party adds each layer. These details establish the packaging’s function and the supply arrangement to assess.

The answer should distinguish the sales pack—the packaging forming a sales unit with the product—from grouped, transport or e-commerce packaging. A fragrance gift box shipped inside a mailer relies on both structures for protection. If the quotation covers only the gift box, the supplier should make that scope clear and identify information needed from whoever provides the mailer.

Follow-up: Can you mark the components and packaging layers covered by your proposal, and identify the information you still need?

2. Who will carry each legal responsibility?

PPWR uses manufacturer as a legal role. An EU jewellery brand commissioning boxes under its own trademark from a factory in China will normally be the PPWR manufacturer. It must arrange the conformity assessment, draw up the technical documentation and issue the EU declaration of conformity. Under Article 16, the packaging supplier must provide the information and documentation the manufacturer needs to demonstrate conformity.

A credible answer identifies the legal entities and who prepares, checks and retains each deliverable. It should also establish any EU importer role and distinguish the producer responsible for extended producer responsibility (EPR): registration, reporting and waste-management funding in the relevant markets. These roles depend on the actual arrangement and can overlap. A clear division of work helps your team use the supplier’s expertise while preserving legal accountability.

Follow-up: Can you put the proposed responsibilities beside the named companies for our supply route, including who will issue the declaration?

3. Which requirements apply to this project now, and which come later?

As of 23 September 2026, the EU Packaging and Packaging Waste Regulation, Regulation (EU) 2025/40, has applied generally since 12 August 2026. A supplier should already be able to support applicable conformity documentation, identification and substance requirements. Later measures have their own start dates and conditions.

Ask for a short requirements list tied to your packaging, with the legal reference, timing and evidence needed. For example, Article 10 sets packaging-minimisation requirements for 1 January 2030; the harmonised material-composition label starts from 12 August 2028 or 24 months after the relevant implementing acts enter into force, whichever is later. Delegated and implementing acts supply further technical rules, so a proposal or expected publication date should be identified as such.

Follow-up: Which items in your proposal address current duties, and what event will trigger a review of the later requirements?

4. Can you describe and quantify every material in the proposed pack?

Look for a controlled bill of materials: a parts list tied to the packaging version, with material descriptions, component weights and references connecting each item to its supplier evidence. For a rigid box, this reaches beyond the greyboard to its wrap paper, inks, coatings, adhesives, insert and closures. The specification should be detailed enough to identify what is being purchased and made.

Useful data states grams per packaging unit, whether weights are measured or estimated, and which values need confirming after sampling. This helps compare constructions and supplies material data for EPR reporting. Supplier shipment quantities then need to be combined with your actual market data; they do not automatically equal the quantities placed on each national market.

Follow-up: Can you show the material and weight breakdown for this design, including items still awaiting confirmation?

5. What exactly does each declaration or test report cover?

Ask the supplier to connect each document to the proposed packaging. For a test report, that means the issuer, sample identity, materials tested, date, method and results. For a supplier declaration, it means a defined material or product, the requirement being addressed and a traceable basis for the statement.

For these paper-packaging projects, one current requirement is the combined limit of 100 mg/kg for lead, cadmium, mercury and hexavalent chromium. Evidence about the board alone leaves other materials, such as a coloured wrap or plastic insert, to be addressed. A four-heavy-metal test supports a conclusion about those substances in the material tested; recyclability and other obligations need their own basis.

A well-supported supplier declaration can contribute to the evidence. Where information is incomplete or its relevance is uncertain, a useful answer identifies the particular gap and a proportionate way to resolve it. The number of documents matters less than whether they address the materials and requirements involved.

Follow-up: Which components and versions does this document support, and what has changed since its sample or specification was assessed?

6. How would you improve recyclability while preserving the product experience?

This question reveals whether the supplier can turn requirements into useful design choices. Ask them to explain the intended collection and recycling route, the assessment method they propose and the effects of coatings, adhesives, inserts and mixed materials. The detailed PPWR design-for-recycling requirements apply from 1 January 2030 or 24 months after the relevant delegated acts enter into force, whichever is later. The supplier should distinguish an assessment using a current method from a claim about a future PPWR performance grade.

A paperboard insert that lifts out may make a fragrance box easier to separate than a permanently bonded foam insert. It also changes how the bottle is supported, removed and protected from rubbing. We can develop and sample such alternatives with you, so the decision considers product protection, appearance, opening feel and supporting evidence together. The useful recommendation explains those consequences for your product.

Follow-up: Which feature of this construction presents the largest recycling difficulty, and what workable alternative would you investigate?

7. How will you justify the pack’s weight, dimensions and empty space?

A credible minimisation proposal explains what prevents further reduction: product protection, packing operations, logistics, information or another necessary function. For the Article 10 assessment, Annex IV calls for design reasoning and supporting evidence. For a watch box, a supplier might compare a shallower insert and smaller lid-and-base structure, then check product movement, compression resistance and packing practicality. The useful output is a justified choice supported by relevant measurements, samples or tests.

Also ask about the finished parcel. For a conventional single-use e-commerce mailer surrounding a separate retail pack, Article 24 sets a 50% maximum empty-space ratio from 1 January 2030 or three years after the relevant implementing acts enter into force, whichever is later. Void-fill materials count as empty space. The supplier therefore needs the product mix and packing arrangement to develop useful mailer sizes; adding more paper cushioning does not resolve excessive space.

Follow-up: Can you show a smaller or lighter option and explain, with evidence, what would be gained or lost?

8. What will you check before we approve artwork and environmental claims?

Ask for an artwork review based on the agreed operator roles and destination markets. It should locate the packaging identifier and required manufacturer and importer information, and explain the permitted presentation for that pack. Future harmonised sorting labels need a separate review against the adopted specifications and their application date. The supplier should identify the source and legal status of any proposed sorting symbol.

Claims also need a defined scope. A recycled-content claim, for example, should identify whether it describes the greyboard or the complete decorated box. For environmental claims about packaging properties regulated by PPWR, Article 14 requires properties exceeding the applicable minimum requirements, a statement of which packaging or part the claim concerns, and support in the technical documentation. For a PPWR reuse claim, seek evidence of repeated packaging use and the relevant reuse system; a gift box’s possible later use for household storage does not establish that.

Follow-up: For each proposed mark or claim, what requirement or evidence supports this exact artwork version?

9. What will you deliver for the technical file and EU declaration of conformity?

Technical documentation under Annex VII should let the responsible manufacturer assess the packaging against the requirements that apply. Relevant contents include intended use, design and material specifications, an assessment of non-conformity risks, the standards or technical methods used, and supporting assessments and reports. Ask to see how these elements connect: a report should be traceable to a material in the specification and to the requirement it helps address.

The EU declaration of conformity is the manufacturer’s formal statement that the identified packaging satisfies applicable requirements. It rests on the conformity assessment and technical documentation. Agree which inputs the supplier will deliver, who will assemble and review the file, and who has authority to sign the declaration. Include the deliverables and their revision references in the quotation’s scope, along with any testing or development still required.

Follow-up: Can you show a redacted example or proposed file index, then trace one conclusion back to the specification and its evidence?

10. Who coordinates specialist work, and what decision will it resolve?

Some projects need a laboratory, a recycling specialist or advice on a legal-role question. A credible supplier can define the question, identify a suitable specialist and prepare the information needed for a useful answer. For testing, that includes the material or finished construction to assess, the sample version, relevant methods and how results will be interpreted.

At CMIC, we can coordinate material suppliers and suitable specialist partners around the packaging project. That can include gathering missing composition information, arranging project-specific tests and translating findings into a revised material or structural choice. Ask for the named coordinator, scope, cost and timing, plus the decision that follows the result. A failure or inconclusive result may require a new sample and further review; the proposal should explain how that would be handled.

Follow-up: If the proposed coating cannot be supported by the available evidence, who will investigate alternatives and confirm the next decision?

11. How will you control substitutions and repeat orders?

Article 15(4) requires procedures to keep series production in conformity, with reassessment where changes could affect it. A supplier’s answer should connect the approved specification and sample to purchasing instructions, production checks and batch records. It should also describe how changes to relevant standards or technical specifications are reviewed.

An adhesive substitution can leave a folding carton looking identical while changing the basis of its material evidence or recycling assessment. Useful change control identifies the new material, checks the consequences, obtains agreed approval before use and updates the affected records. The same attention is needed for changes in paper grade, ink, insert material or component supplier. On a repeat order, ask which version is being made and whether the earlier evidence still applies.

Follow-up: Walk us through an adhesive substitution, from the first proposal to any reassessment, approval and identification of the affected batches.

12. Can we retrieve the right evidence and act on a problem after delivery?

Support continues after shipment. Manufacturers must retain technical documentation and the EU declaration for five years after placing single-use packaging on the market, and ten years for reusable packaging. Manufacturers and importers must provide the required conformity documentation within ten days of a reasoned request from a national authority. Agree a supplier response time that leaves your team room to check and provide the information.

Look for retrievable files linked to packaging types, versions and batches, with clear contact and backup arrangements. If a material report later proves unreliable, the supplier should be able to identify affected orders, preserve the underlying records and support necessary corrective action. Keeping the evidence used for previous production versions makes an older shipment much easier to investigate.

Follow-up: Using an order reference, how would you find its evidence and identify other shipments that might be affected by the same material problem?

Use the answers to compare the scope of support

Compare suppliers against the same proposed pack. For each question, distinguish evidence you can review now from work that still needs completing. This keeps a confident presentation from obscuring a missing deliverable, while giving a thoughtful development proposal fair consideration.

A supplier with a defined investigation can still be a sensible choice. The decision is whether they can complete that work at the right stage, keep the evidence tied to production and make the remaining responsibilities clear. Include the cost and timing of that support when comparing quotations: it affects how much coordination your own team will need to carry.
