A supplier sends you an EN 13432 certificate.
The bag is described as compostable.
Can you now call it a PPWR compliant compostable bag?
Not so fast.
A compostable certificate is useful evidence, but PPWR compliance depends on more than the material.
You also need to know:
- Is the product actually packaging under PPWR?
- Which PPWR rules apply to this packaging?
- Does Article 9 require or allow compostability for this use?
- Does the certificate cover the finished bag?
- What happens to the packaging after use?
- What technical documents are available?
- Which EU Member State will the product enter?
So the answer to the question “Are compostable bags PPWR compliant?” is:
They can meet applicable PPWR requirements, but compostability alone does not make every bag PPWR compliant.
The finished product, application, market and supporting documents all matter.
This page is a product-level buyer checklist. It focuses on what to verify before approving a finished compostable bag, supplier documentation, artwork or bulk order for the EU market.
For the wider regulation, timelines and PPWR framework, see our PPWR Compostable Packaging: 2026 Guide.
Short Answer: Does Compostable Mean PPWR Compliant?
No.
“Compostable” describes an end-of-life property.
“PPWR compliant” refers to compliance with the applicable requirements of Regulation (EU) 2025/40.
Those are different things.
A bag can have valid industrial-compostability evidence and still need further review under PPWR.
For example, you may still need to check:
- product classification;
- Article 9;
- recyclability pathway;
- packaging minimisation;
- labelling;
- technical documentation;
- traceability;
- conformity assessment.
PPWR applies to packaging placed on the EU market, including imported packaging. It entered into force on 11 February 2025 and generally applies from 12 August 2026.

This is why I would avoid treating the phrase “PPWR compliant compostable bags” as a certification logo.
There is no single certificate called:
“PPWR Compostable Bag Certificate.”
Compliance is built from the requirements that apply to the specific packaging.
7-Step PPWR Buyer Checklist for Compostable Bags
Before approving a bulk order, you can use this simple checklist.
Step 1 — Confirm the Product and Its Function
Check:
- What is the bag used for?
- Does it perform a packaging function?
- Who fills it?
- What does it contain?
- What happens after use?
Do not assume that every compostable bag is packaging under PPWR.
Step 2 — Define the Destination Market
Confirm:
- EU Member State;
- importer or distributor;
- retailer requirements;
- intended waste route;
- relevant national rules.
“EU market” is often too broad for a final product review.
Step 3 — Identify the PPWR Pathway
Ask whether the packaging falls under:
- Article 9(1);
- Article 9(2);
- Article 9(3); or
- another PPWR pathway.
For the full legal structure, see our PPWR Article 9 Compostable Packaging Guide.
Step 4 — Verify Compostability Evidence
Check:
- applicable standard or certification;
- certificate holder;
- certificate number;
- validity;
- industrial vs home compostability;
- finished-product scope.
Do not stop at a raw-material certificate.
Step 5 — Freeze the Finished Bag Specification
Confirm:
- material formulation;
- dimensions;
- thickness;
- film colour;
- masterbatch;
- printing;
- ink;
- adhesive;
- labels;
- closure components.
If the finished construction changes, the evidence may need to be reviewed again.
Step 6 — Review PPWR Documentation
Depending on the product, review:
- product specification;
- relevant compostability certificate or test evidence;
- technical documentation;
- conformity-assessment information;
- EU Declaration of Conformity;
- product identification;
- traceability;
- applicable labelling information.
PPWR conformity assessment for Articles 5–12 is governed by Article 38 and Annex VII, while Article 39 covers the EU Declaration of Conformity.
Step 7 — Approve Artwork and Claims
Before mass production, review:
- “compostable” wording;
- industrial vs home-compostable claims;
- certification-mark authorisation;
- disposal instructions;
- required PPWR labelling;
- Member State wording;
- other environmental claims.
Approve the evidence before approving the artwork.
Is the Bag Ready for Buyer Approval?
| Status | What It Means |
|---|---|
| Continue review | Packaging classification or Article 9 pathway is still unclear |
| Hold | Certificate only covers resin/material and finished-bag scope is not confirmed |
| Hold | Target Member State, waste route or printed claims are not defined |
| Review documentation | Product specification is fixed but PPWR technical/conformity documents are incomplete |
| Ready for final internal approval | Product classification, specification, evidence, documentation and artwork have all been reviewed |
Is the Bag Actually Packaging Under PPWR?
Before applying Article 9, first confirm whether the item actually performs a packaging function under PPWR.
A compostable product can be valid without necessarily being “PPWR packaging.”
| Product | First Question |
|---|---|
| Produce bag | Does it contain or present goods at sale? |
| E-commerce mailer | Yes, it normally performs a clear packaging/delivery function |
| Household waste liner | May primarily be a waste-collection product rather than packaging |
| Dog waste bag | May also fall outside the normal packaging function |
Which PPWR Article 9 Path Applies?
Once you confirm that the item is packaging, Article 9 becomes one of the main questions for compostable materials.
Article 9 creates three broad routes.
| Route | Packaging treatment |
|---|---|
| Article 9(1) | Specific packaging must meet industrial compostability requirements |
| Article 9(2) | Member States may require certain additional packaging to be compostable |
| Article 9(3) | Other biodegradable packaging follows a material-recycling pathway |
This means a compostable material does not automatically put the packaging into the composting route.
For the detailed rules, categories and 2028 requirements, see our PPWR Article 9: Which Packaging Must Be Compostable?.
Does EN 13432 Make a Compostable Bag PPWR Compliant?
No.
EN 13432 provides important evidence for industrial compostability, but PPWR asks a wider question: what requirements apply to the finished packaging placed on the EU market?
Buyers still need to review packaging classification, Article 9, finished-product scope, technical documentation, labelling, conformity assessment and other applicable PPWR requirements.
For the detailed relationship, see EN 13432 and PPWR Compliance
Raw-Material Certificate vs Finished-Bag Evidence
This is one of the first things I would check when reviewing a supplier.
Imagine you are ordering:
23 × 33 cm
20 μm
Dark green
Black logo print
15 bags per roll
Your supplier sends an EN 13432 certificate.
Good.
Now ask:
What exactly does that certificate cover?
It may cover:
- resin;
- compound;
- base film;
- finished bag;
- certain thickness ranges;
- certain printing systems.
These are not the same.
A finished compostable bag may contain:
- PBAT;
- PLA;
- starch;
- additives;
- colour masterbatch;
- printing ink;
- adhesive;
- labels;
- closures.
That is why the phrase:
“Our raw material is certified.”
should be the start of the discussion, not the end.
For a custom OEM bag, the question is not only “Is the resin certified?” It is “Does the available evidence support the finished configuration I am buying?”
A Practical Certificate Check
Before accepting a compostability certificate, I suggest checking:
| Check | Question to ask |
| Certificate holder | Who owns the certificate? |
| Certificate body | Who issued it? |
| Certificate number | Can it be verified? |
| Validity | Is it still current? |
| Product scope | Resin, film or finished bag? |
| Thickness | Does it cover your thickness? |
| Colour | Is the masterbatch within scope? |
| Printing | Is the printed version covered? |
| Components | Are additives and other parts included? |
| Composting route | Industrial or home composting? |
Do not be afraid to ask these questions.
They are normal B2B sourcing questions.

Does Printing Affect PPWR or Compostability?
Printing can matter.
It becomes part of the finished packaging.
Suppose the base film has compostability evidence, but your project adds:
- two-colour logo printing;
- custom Pantone masterbatch;
- an adhesive label.
You now have a different finished product from the plain base film.
That does not automatically mean the product fails.
It means the scope needs to be checked.
For private-label projects, I recommend reviewing the printing and compostability evidence before mass production artwork is approved.
Changing artwork later is expensive.
Checking earlier is much easier.
If certification marks will appear on the artwork, confirm mark-use authorisation before final production approval.
Industrial Compostable Is Not the Same as Home Compostable
Industrial and home compostability are separate claims.
EN 13432 relates to industrial compostability and should not automatically be used to support a “HOME COMPOSTABLE” claim.
If home compostability will appear on the bag or retail packaging, verify that the finished product has appropriate supporting certification or evidence.
See our Home vs Industrial Compostable Guide for the detailed distinction.
PPWR Review by Compostable Bag Type
| Bag Type | Main Buyer Question |
|---|---|
| Produce bags | Does the bag fall within very lightweight/lightweight carrier-bag definitions and what does the Member State require? |
| Shopping bags | Does Article 9(2) or a national rule apply to the specific thickness and format? |
| E-commerce mailers | Does Article 9(3) direct the biodegradable packaging toward material recycling? |
| Garbage / food-waste bags | Is the product actually packaging under PPWR, or primarily a waste-collection product? |
| Dog waste bags | Does the item perform a packaging function at all? |
The same compostable material can have a different PPWR assessment depending on the bag’s function and market.
Product classification comes before the compostability claim.
PPWR Document Checklist for EU Importers
This is where the discussion moves beyond certificates.
PPWR places duties on manufacturers and importers.
Manufacturers must ensure packaging complies with applicable Articles 5–12 requirements, carry out the relevant conformity assessment, and prepare technical documentation. Importers also have duties to check conformity assessment, documentation, labelling and manufacturer information before placing imported packaging on the EU market.
Depending on the product, an EU buyer may need to review:
Compostability evidence
- EN 13432 certificate or test evidence
- Certificate number
- Certificate holder
- Validity
- Certificate scope
- Finished-product coverage
Product information
- Material structure
- Film thickness
- Dimensions
- Colour
- Printing
- Ink
- Masterbatch
- Additives
- Intended use
PPWR-related documents
- Technical documentation
- Applicable conformity assessment
- EU Declaration of Conformity
- Product identification
- Traceability information
- Applicable labelling information
Market-specific documents
- Food-contact documentation, if relevant
- Member State requirements
- Retailer requirements
- Local certification or collection-system requirements
A folder containing 20 certificates is not automatically better than a folder containing five.
The documents need to match the product.
What Is the EU Declaration of Conformity?
PPWR includes a conformity-assessment framework.
Once the applicable requirements have been demonstrated, the manufacturer draws up an EU Declaration of Conformity under Article 39. The declaration identifies the packaging and states that the applicable requirements laid down in or pursuant to Articles 5–12 have been demonstrated.
It is not the same as:
- an EN 13432 certificate;
- a material data sheet;
- a factory certificate;
- a laboratory test report.
Each document has a different purpose.
PPWR also requires the relevant technical documentation and EU Declaration of Conformity to be retained for specified periods. For single-use packaging, the retention period is generally five years.
Manufacturer vs Importer: Who Is Responsible?
This question matters when buying from China.
The Chinese factory may be the manufacturer.
The EU company placing imported packaging on the Union market may be the importer.
Both can have obligations.
Manufacturer
The manufacturer needs to address matters such as:
- applicable PPWR requirements;
- conformity assessment;
- technical documentation;
- product identification;
- Declaration of Conformity;
- traceability.
Importer
The importer needs to check matters such as:
- whether conformity assessment has been carried out;
- whether technical documentation exists;
- whether required marking and labelling are present;
- whether manufacturer information is correct;
- whether the necessary documents accompany the packaging.
So an EU importer should not simply say:
“The factory told me it complies.”
Verification matters.
A Realistic Example: A Private-Label Produce Bag
Suppose you are an EU distributor sourcing:
Compostable produce bags
12 μm
Green
300 bags per roll
One-colour printing
The supplier sends an EN 13432 certificate.
What should you do?
First
Check whether the 12 μm bag falls under the very lightweight carrier-bag definition.
It does, because it is below 15 μm.
Second
Check the Member State.
Article 9(2) allows national compostability requirements under certain conditions.
Third
Check the certificate.
Does it cover:
- the film?
- 12 μm?
- green masterbatch?
- printing?
Fourth
Review:
- product specification;
- artwork;
- environmental claim;
- technical documents.
Now you have a product review.
Not just a certificate review.
That is the difference.
Red Flags When a Supplier Says “PPWR Compliant”
I would ask more questions if you see statements such as:
“All our biodegradable bags are PPWR certified.”
PPWR is not one certification scheme for all biodegradable bags.
“Our raw material has EN 13432, so every finished bag complies.”
Certificate scope should be checked against the finished product.
“PPWR requires all EU packaging to become compostable.”
Incorrect.
Article 9 creates limited compostability pathways, while other biodegradable packaging can be directed toward material recycling.
“Home compostable and industrial compostable mean the same thing.”
They do not.
“The same packaging works in every EU country.”
Not always.
Member State requirements can still matter.
These are not reasons to reject a supplier immediately.
They are reasons to ask better questions.
“We have an EN 13432 certificate, so no EU Declaration of Conformity is needed.”
These documents serve different purposes. Compostability evidence does not replace the PPWR conformity-assessment and documentation requirements applicable to the packaging.

FAQ
Are compostable bags PPWR compliant?
Some compostable bags can meet the PPWR requirements applicable to their use, but compostability alone does not prove full PPWR compliance.
The packaging type, Article 9 pathway, target market, certification scope, technical documentation and other relevant PPWR requirements must also be checked.
Is there a PPWR certificate for compostable bags?
PPWR does not create one universal “PPWR compostable bag certificate.”
Compliance is demonstrated through the applicable requirements, conformity assessment, technical documentation and other supporting evidence.
Does EN 13432 mean a compostable bag is PPWR compliant?
No.
EN 13432 supports assessment of industrial compostability, but it does not cover the full PPWR framework.
Read our EN 13432 and PPWR Compliance Guide for more detail.
Does a raw-material certificate cover a finished compostable bag?
Not automatically.
The certificate scope should be checked against the finished film, thickness, masterbatch, printing, inks and other relevant components.
What documents should an EU importer request?
EU importers should request documents that match the finished packaging being purchased, not only the base resin. Depending on the project, this may include:
- finished-product specification;
- material composition;
- applicable compostability certificate and certificate scope;
- relevant test reports;
- PPWR technical documentation;
- product identification and traceability information;
- EU Declaration of Conformity, where applicable;
- artwork and environmental-claim information;
- food-contact documentation, where relevant.
The key check is whether the documentation supports the actual finished bag specification, including thickness, colour, printing and other components.
Who is responsible for PPWR compliance when importing packaging from China?
The manufacturer and EU importer can have separate obligations under PPWR.
Importers should verify that required conformity assessment, technical documentation, labelling and manufacturer information are in place before placing the packaging on the EU market.
Should artwork be approved before the compliance documents are reviewed?
No. Where environmental claims, certification marks or disposal instructions appear on the packaging, review the applicable evidence and documentation before final artwork approval.
Conclusion
A compostable bag is not automatically a PPWR compliant compostable bag because it carries an EN 13432 certificate.
The certificate may be important, but it is only one part of the review.
Before approving an EU project, confirm:
- the product and its packaging function;
- the applicable PPWR pathway;
- the destination Member State;
- finished-product certification scope;
- the final material, thickness, colour and printing;
- technical documentation and conformity information; and
- artwork and environmental claims.
The goal is not to collect as many certificates as possible.
The goal is to make sure the evidence matches the finished product you are actually placing on the EU market.
If you are sourcing a private-label compostable bag for Europe, send us your target country, bag type, size, thickness, printing requirements and estimated order quantity.
This article provides general information for packaging buyers and does not constitute legal advice. Requirements depend on the product, intended use, target Member State and applicable PPWR measures.
