EN 13432 Requirements for Compostable Packaging Compliance
EN 13432 testing is used to evaluate whether packaging can be recovered through industrial composting and biodegradation. For compostable bags, films and flexible packaging sold in the EU market, EN 13432 is the core standard buyers use to check biodegradation, disintegration, heavy metal limits and compost quality.
This guide explains EN 13432 testing requirements in practical B2B terms, including what the standard covers, what documents buyers should request, and how to check whether packaging is truly EN 13432 compliant.

What Is EN 13432?
EN 13432 is a European standard for packaging recoverable through composting and biodegradation. It is commonly used to assess whether packaging is suitable for industrial composting conditions.
For B2B buyers, EN 13432 is not just a material claim. It is a packaging-level compliance standard. The final packaging item, including film, paper structure, inks, adhesives, coatings, labels and additives, should be considered within the certified scope.
In Germany, the standard is commonly referenced as DIN EN 13432. In the UK and other markets, buyers may also see terms such as BS EN 13432 or EN13432. These terms usually refer to the same European compostability standard adopted in different national systems.
EN 13432 Testing Requirements: The Four Core Tests
EN 13432 testing is not a single test. It is a test scheme used to evaluate whether packaging is suitable for recovery through industrial composting and biodegradation.
The standard typically focuses on four main areas:
- Biodegradation: whether the material converts into carbon dioxide, water and biomass under controlled composting conditions.
- Disintegration: whether the packaging physically breaks down during the composting process.
- Heavy metal and chemical safety limits: whether the material contains restricted substances above allowed levels.
- Ecotoxicity and compost quality: whether the resulting compost has a negative effect on plant growth or compost quality.
A product should not be described as EN 13432 compliant unless the relevant material, structure and components are covered by valid test evidence or third-party certification.
EN 13432 Standard: What Packaging Must Prove
The EN 13432 standard defines requirements for packaging recoverable through composting and biodegradation. It is used to evaluate both the breakdown behavior of the packaging and the quality of the final compost.
For buyers, this means EN 13432 compliance should answer three practical questions:
- Can the packaging biodegrade under industrial composting conditions?
- Can the packaging disintegrate during the composting process?
- Will the final compost remain safe for plant growth and soil quality?
This is why EN 13432 is mainly linked to industrial composting, not backyard or home composting.
EN 13432 Compliant Packaging: What Buyers Should Check
EN 13432 compliant packaging should be supported by more than a supplier statement. Before approving a compostable packaging order, buyers should check whether the certificate or test evidence matches the actual product being purchased.
Key checks include:
- Product type covered by the certificate
- Material structure and thickness range
- Printing inks, adhesives, labels and additives
- Certificate number and validity date
- Certification body or testing laboratory
- Authorized use of compostable logos such as Seedling or OK compost INDUSTRIAL
- Intended disposal route, such as industrial composting rather than home composting
If any of these points are unclear, the product may create compliance, labeling or customer claim risk in the EU market.
Material and Component Requirements
One common mistake is thinking: “If the film is compostable, the whole package is compostable.”
In reality, EN 13432 packaging requirements apply to the whole packaging item, not only the base resin or film. For flexible packaging, this may include the main compostable film, printed inks, adhesives, coatings, labels and any functional additives.
For B2B buyers, the safest approach is to ask whether the full packaging structure is covered by the certification scope. This is especially important for private-label bags, printed mailer bags, shopping bags, produce bags and laminated packaging.
Certification, Test Reports and Documentation
EN 13432 requirements are normally demonstrated through third-party certification, test reports or compliance documentation. For EU markets, common certification systems include Seedling and OK compost INDUSTRIAL, issued by recognized certification bodies.
For B2B procurement, buyers should request:
- A valid certificate with certificate number and validity date
- Clear product scope, including product type and variants
- Material or thickness range covered by the certificate
- Certifier name or testing laboratory information
- Supporting test reports or compliance statements where needed
- Authorization for logo use if compostable logos are printed on the packaging
For the full certification process, certificate verification and logo use, see our EN 13432 Certification Guide.
Labeling and Claim Requirements
EN 13432 labeling requirements are not only about putting “compostable” on the package. The main risk is misleading environmental claims, especially when a product is industrially compostable but not suitable for home composting.
For B2B packaging, safer wording includes:
- Certified compostable according to EN 13432
- Industrially compostable
- Suitable for industrial composting where facilities exist
Buyers should be cautious with vague terms such as “biodegradable” or “eco-friendly”. These claims can create confusion if they are not supported by a recognized standard, proper disposal instructions and accurate certification scope.
When EN 13432 Is Not Enough
EN 13432 proves industrial compostability, but it does not guarantee acceptance in every waste collection system.
Certified compostable packaging may still face restrictions if local composting facilities run shorter treatment cycles, if sorting systems cannot identify compostable plastics reliably, or if country-level rules require additional labeling or certification.
For example, Germany has specific market and biowaste collection requirements. If you are selling compostable packaging into Germany, see our Germany Compostable Packaging Regulations Guide.
EN 13432 vs ASTM D6400 vs AS 4736
EN 13432 is the main European standard for industrially compostable packaging. ASTM D6400 is commonly used in the United States, while AS 4736 is used in Australia for industrial composting.
These standards are similar in purpose, but they are not always interchangeable for market access. B2B buyers should confirm which standard is required for the target country before ordering compostable packaging.
For a detailed comparison, see our EN 13432 vs ASTM D6400 vs AS 4736 guide.

Use this checklist when reviewing any EN 13432 compostable packaging supplier:
- EN 13432 or DIN EN 13432 evidence is available
- Certificate number, issuer and validity date are clear
- Certification scope matches the product type and thickness
- Printing inks, adhesives, labels and additives are considered
- Compostable logo use is authorized
- The disposal route is industrial composting, not home composting unless separately certified
- Country-level requirements are reviewed before market launch
- Supplier can provide stable materials, documentation and private-label support
Key Takeaways
EN 13432 testing evaluates whether packaging can biodegrade, disintegrate and leave compost that is safe for plant growth under industrial composting conditions.
For B2B buyers, EN 13432 should be treated as a compliance baseline, not a simple marketing label. The safest sourcing approach is to verify the certification scope, check the full packaging structure, use accurate claims and confirm country-level acceptance before scaling orders.
