For rigid boxes sourced from China, the most useful supplier file usually includes:
- packaging identification;
- component-level material information;
- packaging BOM;
- component and total weights;
- relevant material specifications;
- supplier declarations where applicable;
- relevant test reports or chemical evidence;
- drawings or structural specifications;
- version/revision control;
- change-notification records.
The goal is not to collect the largest possible folder.
The goal is to create an evidence chain that answers:
“What exactly is this packaging, what is it made from, which requirements apply, and what evidence supports our conclusion?”

Why a “PPWR Compliant Certificate” Is the Wrong Starting Question
Direct answer: PPWR works through conformity assessment, technical documentation and an EU Declaration of Conformity for the responsible manufacturer. A supplier can provide critical evidence, but a generic supplier letter does not replace the manufacturer’s compliance process.
A buyer asks:
“Please send your PPWR certificate.”
The supplier replies:
“Our boxes are PPWR compliant.”
Both sides may feel the task is complete.
It is not.
Under Regulation (EU) 2025/40, manufacturers are required to carry out the applicable conformity assessment, prepare technical documentation and, when conformity has been demonstrated, draw up an EU Declaration of Conformity.
The regulation also gives packaging and packaging-material suppliers an information obligation: suppliers must provide manufacturers with the information and documentation necessary to demonstrate conformity.
The useful question is therefore not:
“Do you have one PPWR certificate?”
It is:
“What evidence can you provide for this packaging specification?”
Who Is Responsible: Supplier, Manufacturer or Importer?
Direct answer: The legal role depends on the supply chain, but PPWR responsibilities are not all placed on the packaging factory. The supplier provides necessary packaging information; the manufacturer carries the relevant conformity responsibilities; and importers must verify required conformity steps and documentation before placing packaging on the EU market.
For a typical custom rigid-box project, several parties may be involved:
- Chinese packaging manufacturer;
- EU brand owner;
- contract packer;
- EU importer;
- distributor;
- retailer;
- e-commerce seller.
Supplier Obligation
Article 16 requires suppliers of packaging or packaging materials to provide the manufacturer with information and documentation necessary to demonstrate conformity.
That makes supplier data a real compliance input.
Manufacturer Obligation
Article 15 requires manufacturers to:
- place only conforming packaging on the market;
- carry out the conformity assessment;
- prepare technical documentation;
- draw up the EU Declaration of Conformity when conformity has been demonstrated.
Importer Obligation
Article 18 requires importers to verify, before placing packaging on the market, that the manufacturer has carried out the conformity assessment and prepared the required technical documentation, alongside other applicable requirements.
What This Means Commercially
The factory should not pretend to replace the buyer’s regulatory function.
But the factory also cannot simply say:
“PPWR is your problem, not ours.”
A strong supplier supports the buyer with accurate, structured and traceable packaging evidence.
What Should Be in a Useful Rigid Box Supplier Evidence Pack?
Direct answer: A useful supplier evidence pack should connect the physical rigid box to specific materials, specifications and supporting documents. The buyer should be able to trace each document back to the packaging version actually being purchased.
1. Packaging Identification
Include:
- customer or project name;
- SKU or packaging code;
- box style;
- dimensions;
- revision number;
- artwork version;
- supplier name;
- manufacturing site where relevant;
- production or batch reference where relevant.
A test report becomes much less useful if nobody can prove which box version it relates to.
2. Packaging BOM
Example:
| Component | Material | Key specification | Weight |
|---|---|---|---|
| Structural board | Greyboard | 1200 gsm | 210 g |
| Outer wrap | Printed art paper | 157 gsm, matte finish | 42 g |
| Closure | Magnet | 4 pcs | 8 g |
| Insert | Molded fibre | natural pulp | 36 g |
| Adhesive | Applicable supplier specification | — | 6 g |
| Total | — | — | 302 g |
The exact fields depend on the product.
The important point is that the BOM describes the real structure.
For material and design questions, read PPWR and Rigid Boxes: Magnets, Foam Inserts, Lamination and Empty Space Explained.
3. Material Specifications
Depending on the packaging, this may include:
- greyboard grade;
- wrapping-paper specification;
- recycled-content information where relevant;
- plastic-film specification;
- molded-fibre specification;
- foam density;
- magnet specification;
- coating information;
- adhesive data where relevant.
The goal is not to disclose every proprietary production detail.
The goal is to identify the material clearly enough for the buyer’s conformity work.
4. Chemical or Substance Evidence Where Relevant
Direct answer: PPWR includes substance-related packaging requirements, so buyers may need supporting material or test evidence depending on the packaging and its intended use. Evidence should match the actual material and risk rather than applying a generic test program to every rigid box.
PPWR maintains a limit on the sum of lead, cadmium, mercury and hexavalent chromium in packaging and packaging components.
Food-contact packaging also has specific PFAS restrictions from 12 August 2026.
That does not mean every jewellery box, perfume box or electronics box requires the same food-contact testing.
Ask:
“Which evidence applies to this exact material specification?”
rather than:
“Please send every certificate you have.”
5. Supporting Test Reports and Declarations
A supplier may hold:
- board or paper declarations;
- chemical test reports;
- recycled-content evidence;
- material declarations;
- supplier compliance statements;
- factory quality records;
- product-specific testing;
- packaging-performance records.
Each document should answer:
- What material or component does it cover?
- Which version or specification does it cover?
- What requirement does it support?
A folder full of unrelated PDFs is not the same as a controlled evidence pack.
6. Drawing, Dieline or Structural Specification
Direct answer: The rigid-box structure should be documented well enough to connect the material evidence to the actual packaging design.
This becomes particularly important for:
- magnetic closures;
- hidden plastic parts;
- multi-layer inserts;
- windows;
- ribbons;
- pull tabs;
- laminated wraps;
- mixed-material accessories.
The drawing does not need to expose unnecessary supplier IP.
It needs to identify the construction clearly enough for the evidence to make sense.
7. Revision and Change Control
Imagine a buyer approves:
- 1200 gsm greyboard;
- molded-fibre insert;
- unlaminated specialty paper.
Six months later, the supplier changes the insert source or paper finish.
The box may look almost identical.
The compliance evidence may no longer describe the same specification.
Buyer Best Practice
Agree on a change-notification rule covering:
- board grade;
- paper;
- lamination;
- coating;
- adhesive;
- insert material;
- magnet quantity;
- structural dimensions;
- key supplier substitutions.
PPWR requires manufacturers to take relevant changes in design or packaging characteristics into account when maintaining conformity.
This makes version control a procurement issue, not merely a QC issue.
What Does Annex VII Technical Documentation Actually Need?
Direct answer: Annex VII requires technical documentation capable of supporting an assessment of the packaging’s conformity with applicable PPWR requirements. It can include a general description, design and manufacturing information, applicable standards or specifications, assessment evidence, calculations and test reports where relevant.
The rigid-box supplier does not necessarily own the buyer’s complete Annex VII file.
But the supplier should provide the packaging evidence needed to build it.
A useful way to think about this is:
Supplier evidence → technical documentation → conformity assessment → EU Declaration of Conformity
Supplier evidence is an input.
The Declaration of Conformity is the formal output of the responsible manufacturer’s conformity process.
What Should a Buyer Ask During the RFQ Stage?
Direct answer: The best time to request packaging evidence is before mass production, not after the goods are already on the way to Europe.

What a Rigid Box Supplier Should — and Should Not — Promise
Direct answer: A responsible supplier can provide accurate packaging data, material evidence and design support. It should not automatically promise that one generic certificate makes the buyer legally compliant in every EU market.
A Supplier Can Reasonably Provide
- material list;
- packaging BOM;
- component weights;
- total weight;
- material specifications;
- relevant supplier declarations;
- available test reports;
- structural drawings;
- revision control;
- change notifications;
- alternative-material options.
A Supplier Should Be Cautious About Promising
- “one certificate covers all PPWR obligations”;
- “this box is legally compliant in every EU country”;
- “FSC means PPWR compliant”;
- “mono-material is mandatory for every rigid box”;
- “this is officially PPWR Grade A” without a valid assessment basis;
- “EPR registration is the same in every Member State.”

FAQ
Does PPWR require packaging suppliers to provide information?
Yes. Article 16 requires suppliers of packaging or packaging materials to provide manufacturers with information and documentation necessary to demonstrate conformity.
Is a supplier’s “PPWR compliant” declaration enough?
Not by itself. The responsible manufacturer needs technical documentation and evidence supporting the applicable conformity assessment.
Who creates the EU Declaration of Conformity?
The manufacturer draws up the EU Declaration of Conformity once compliance has been demonstrated.
Does a factory have to disclose all confidential manufacturing information?
Not necessarily. Evidence should be sufficient to identify and assess the packaging without disclosing unrelated proprietary information.
How long should technical documentation be retained?
PPWR provides retention periods of five years for single-use packaging and ten years for reusable packaging.
What happens when a material changes?
If the change may affect conformity, the documentation and assessment may need updating. This is why revision control matters.
The Supplier Question That Saves the Most Time
Instead of asking:
“Are you PPWR compliant?”
ask:
“For this exact rigid-box specification, what material, weight and evidence package can you provide?”
That one change creates a much better procurement conversation.
If your team is sourcing rigid boxes from China and wants to structure the supplier request before sampling or mass production, send HiPack your:
- RFQ;
- box structure;
- material specification;
- supplier questionnaire;
- documentation checklist.
We can map which packaging data can be provided from the factory side and identify gaps before production begins.
