EN 13432 Certification: How Buyers Can Verify Compliance
Table of Contents
EN 13432 is the most widely used European standard for compostable packaging.
However, simply seeing “EN 13432 certified” on a product or datasheet does not automatically mean the product is compliant.
For buyers, importers, and brand owners, knowing how to verify EN 13432 certification is essential to avoid non-compliant products, customs risks, and downstream regulatory issues.
This page explains what EN 13432 certification really means, what documents buyers should request, and how to verify whether a certificate is valid and applicable.
What Is EN 13432 Certification?
EN 13432 is a European standard that defines the requirements for packaging to be considered industrially compostable.
To comply with EN 13432, a packaging product must meet all of the following criteria:
- Biodegradation – the material breaks down into CO₂, water, and biomass
- Disintegration – the product physically fragments during industrial composting
- No negative impact on compost quality
- Limits on heavy metals and harmful substances
EN 13432 applies to industrial composting conditions, not home composting.

Why Buyers Must Verify EN 13432 Compliance
Many buyers assume that EN 13432 compliance is simple. In practice, this is where most problems occur.
Common risks include:
Certificates issued for raw materials, not finished bags
Certificates that have expired or been withdrawn
Certificates that apply to different thicknesses or formulations
Misuse of EN 13432 logos without valid certification
For importers and private label brands, these issues can result in:
Customs delays or rejections
Regulatory non-compliance
Customer complaints or recalls
Loss of distributor or council contracts
Verification is not optional — it is a basic due diligence step.
Step-by-Step: How to Verify an EN 13432 Certificate
Step 1: Confirm the Certificate Is for the Finished Product
EN 13432 certification must apply to the finished packaging product, not just the raw material (PLA, PBAT, blends).
Ask clearly:
Is this certificate issued for the final bag, or only for the resin?
If the certificate only covers raw materials, the finished product is not EN 13432 certified.
Step 2: Check the Issuing Certification Body
A valid EN 13432 certificate should be issued by a recognized third-party certification body, such as:
TÜV Austria
DIN CERTCO
TÜV Rheinland
Other accredited EU bodies
The certificate should clearly show:
Certification body name and logo
Certificate number
Scope of certification
If the issuer is unclear or unverifiable, treat the claim with caution.
Step 3: Verify the Certificate Number
Buyers should always verify the certificate number directly through the certification body.
Check:
Is the certificate number searchable on the issuer’s website?
Does the company name match the supplier?
Is the certificate active (not expired or suspended)?
If a supplier cannot provide a verifiable certificate number, this is a red flag.
Step 4: Review Product Scope and Specifications
EN 13432 certificates are issued with specific conditions, including:
Product type
Thickness range
Material formulation
Intended composting environment
Make sure:
The thickness you are buying is covered
The formulation has not changed
The product type matches the certificate scope
A certificate does not automatically cover all bag sizes or thicknesses.
Step 5: Request Supporting Test Documentation
A compliant supplier should be able to provide supporting documents, such as:
Disintegration test reports
Biodegradation test results
Heavy metal analysis
Compost quality assessment
These documents help confirm that the certification is based on real testing, not marketing claims.

EN 13432 vs Other Compostable Standards
EN 13432 is not universal. Buyers should understand how it compares to other standards:
EN 13432 – Industrial composting (EU)
OK Compost INDUSTRIAL – Industrial composting (certification scheme)
OK Compost HOME – Home composting
ASTM D6400 / BPI – United States
AS 4736 / AS 5810 – Australia
One product does not automatically meet all standards.

Common Buyer Mistakes with EN 13432 Certification
Buyers frequently encounter issues due to:
Accepting certificates without verification
Confusing raw material compliance with product certification
Ignoring thickness or formulation limitations
Relying on outdated certificates
These mistakes often surface after shipment, when correction is costly.
Who Should Perform EN 13432 Verification?
EN 13432 verification should be performed by:
Importers and distributors
Private label brands
Procurement teams
Compliance and quality managers
If you are responsible for placing compostable packaging on the EU market, verification is part of your compliance obligation.
Final Notes for Buyers
EN 13432 certification is a technical and legal claim, not a marketing label.
Buyers who take the time to verify certificates protect themselves from risk, ensure regulatory compliance, and build more reliable supply chains.
If a supplier cannot clearly explain or verify their EN 13432 certification, that alone is valuable information.
How German B2B Buyers Evaluate Compostable Packaging Suppliers
German buyers focus strongly on risk reduction.
Beyond certification, they evaluate suppliers based on:
- Completeness of certification documentation
- Correct and consistent labeling
- Understanding of German regulations
- Supply stability and material consistency
Certification alone is not enough. Buyers look for suppliers who understand how regulations are applied in real market conditions.
FAQ
