EN 13432 compliance is often requested by European buyers, global distributors and multinational foodservice brands when sourcing compostable packaging. But for procurement, the question is not simply whether a supplier says “EN 13432 compliant.” The question is which documents prove the claim, which product models are covered and whether the evidence applies to the finished packaging being purchased.
This guide is written for buyers who need to evaluate a document package for bagasse tableware, molded fiber food packaging, clamshell containers, trays, bowls and related foodservice items. It focuses on the documents to request and how to read their scope.
The certificate is the summary document that buyers usually ask for first. It should show the certificate holder, certification body, product or product family, standard reference, validity period and certificate number. For EN 13432-related compostability claims, certification bodies such as DIN CERTCO and TUV AUSTRIA provide programs that buyers commonly encounter in the market.
A certificate is not just a marketing document. It defines the scope. Buyers should check whether the certificate covers the exact material, product type, dimensions, thickness range, color and production site relevant to the purchase.
The test report is the technical evidence behind the certificate or compliance claim. It may include results for biodegradation, disintegration, compost quality and limits for regulated substances. The certificate tells you the product is certified within a defined scope; the test report shows the testing basis used to support the conclusion.
Buyers do not always need every raw lab page for routine orders, but they should request test reports for major tenders, customer audits or when the certificate scope is unclear. If the supplier provides only a certificate and refuses any supporting technical explanation, that is a sign to ask more questions.
A declaration of conformity is the supplier’s formal statement that the product supplied conforms to the stated standard or requirements. It should identify the company issuing the declaration, the product models covered, the relevant standard, the date of issue and the responsible signature or authorization.
This document is useful because it connects the commercial product being shipped to the compliance claim. For a buyer, the declaration should not be generic. It should list or reference the specific SKUs, models or product family covered by the order.
EN 13432 evidence should be supported by a clear product material description. For molded fiber and bagasse packaging, this may include the main fiber source, additives, coating status, color, thickness range and intended application. The material description helps buyers understand whether the tested or certified item matches the current production item.
If a product has a special barrier coating, printed design, pigment or laminate structure, ask whether that version is included in the certificate scope. A plain uncoated product and a coated product may require different evidence.
One of the most important checks is whether the certificate applies to the product models being purchased. A certificate may cover a series, but that series should be traceable to item numbers, dimensions or product descriptions. Buyers should request a model list or cross-reference table when supplier item numbers differ from buyer SKUs.
This matters for importers and distributors that sell the same factory product under several customer codes. The document package should connect factory model, buyer SKU, product name, size, material and case pack.
Check the certificate expiry date and the issuing certification body. A current certificate from a recognized certification body carries more procurement value than an old internal statement. If the certificate has expired, ask whether renewal is complete and whether the product remains unchanged.
Also confirm whether the certification body is the one named on the document and whether the certificate number can be checked through the certification body’s public system or directly with the issuer. A PDF alone is weaker than a document that can be verified.
| Document | What it should show | Best use in buyer review |
|---|---|---|
| Certificate | Certificate holder, standard reference, product scope, certificate number, validity and certification body. | Confirm whether the product family is certified within the stated scope. |
| Test report | Technical testing basis for biodegradation, disintegration, compost quality and restricted substances where applicable. | Support major tenders, customer audits and unclear certificate scopes. |
| Declaration of conformity | Supplier statement linking the compliance claim to ordered models or SKUs. | Connect the certificate to the commercial product being shipped. |
| Material description | Fiber source, coating status, additives, color, thickness range and intended application. | Check whether current production matches the certified or tested version. |
| Model list or SKU cross-reference | Factory model, buyer SKU, dimensions, material and product description. | Prevent using one certificate to approve an uncovered product size or variant. |
Raw-material certification can support an EN 13432 file, but it is not the same as finished-product certification. A certified material does not automatically mean that every finished package made from it is certified. Shape, thickness, coatings, inks and additives can affect compostability performance.
For foodservice buyers, finished-product certification is stronger because it applies to the item entering the market. Raw-material evidence is useful when reviewing the supply chain, but it should be connected to product-level declarations and finished-item scope.
Zhongxin supplies molded fiber and bagasse food packaging for buyers that need product-level compliance files, sample review and export documentation. Explore our food packaging solutions, molded fiber packaging and compostable clamshell containers, or contact us to request the EN 13432-related document package for your target product.
Buyers should request the certificate, supporting test report, declaration of conformity, product material description, covered model list, validity period and certification body details.
Not by itself. Raw-material certification can support the evidence file, but finished-product scope is stronger because shape, thickness, coatings, inks and additives can affect compostability performance.
The model list connects the certificate to the actual product being purchased. Without it, buyers may accidentally apply one certificate to a different size, material structure or SKU.
Buyers should check whether the certificate is still valid and whether the product formulation or manufacturing site has changed since certification. Expired or outdated evidence should be renewed before approval.
