Quick Summary: EN 13432 vs ASTM D6400 for Export Buyers
EN 13432 and ASTM D6400 are both widely used technical references for industrial or commercial compostability, but they are not the same standard, they are not certification bodies, and they are not universal legal approvals.
- EN 13432 is a European standard for packaging recoverable through composting and biodegradation. Certification schemes operated by organizations such as TÜV AUSTRIA or DIN CERTCO may use EN 13432 as part of their industrial-compostability assessment.
- ASTM D6400-26 is the current active ASTM edition for plastics and products made from plastics designed for aerobic composting in municipal or industrial facilities. D6400-23 is a previous edition.
- BPI is not ASTM D6400. BPI is a North American third-party certification program that uses ASTM D6400 as its base commercial-compostability standard and may use other ASTM assessment routes depending on product construction.
- Industrial compostability is not home compostability. A product meeting EN 13432 or ASTM D6400 should not automatically be marketed as home compostable.
- Compostability is not food-contact compliance. Buyers must review food-contact, chemical, labeling, PFAS, PPWR and other destination-market requirements separately.
- Certificate scope matters more than the logo alone. Buyers should verify the certificate holder, product or SKU, material structure, thickness, coating, printing, production site and current certification status.
Current Standard Status — September 2026
ASTM D6400-26 is the current active edition. ASTM International lists D6400-26 as active, while D6400-23 is a previous edition. The 2026 revision strengthens the technical baseline used for compostable plastics and products intended for controlled municipal or industrial aerobic composting.
For Europe, EN 13432 remains an important industrial-compostability reference. Under the 2026 European Commission PPWR guidance, the existing EN 13432 standard can be used as guidance while the EU develops updated harmonised standards under Regulation (EU) 2025/40. Buyers should therefore distinguish an EN 13432-related certificate from complete PPWR conformity.
For importers, distributors, foodservice brands and private-label buyers, the practical question is not simply, “Does the supplier have EN 13432 or ASTM D6400?” The stronger question is:
Which standard and certification scheme applies to this exact finished product, destination market, composting route and environmental claim—and does the current certificate actually cover the SKU being purchased?
Bioleader® recommends reviewing compostability evidence together with food-contact documentation, product construction and destination-market requirements. Buyers can start with Bioleader®’s Certificates & Test Reports page and then match the available documentation to the selected product rather than assuming that one certificate applies to an entire product catalogue.
What Is EN 13432?
EN 13432 is a European standard for packaging recoverable through composting and biodegradation. It establishes a technical framework for assessing whether packaging is suitable for controlled industrial composting, including biodegradation, disintegration, material characteristics and the effect of the resulting compost.
| EN 13432 Question | Buyer Interpretation |
|---|---|
| What does it evaluate? | Industrial-compostability performance of eligible packaging, including biodegradation, disintegration, regulated constituents and compost-quality effects. |
| Is EN 13432 a certification body? | No. EN 13432 is a technical standard. Third-party certification schemes may assess products against EN 13432 and issue their own certification marks or certificates. |
| Does EN 13432 mean home compostable? | No. Industrial compostability and home compostability are different claims and require different evidence. |
| Does EN 13432 prove food-contact safety? | No. Food-contact suitability must be verified separately for the material, product and intended use. |
| Does it automatically prove PPWR compliance? | No. EN 13432-related evidence may support a compostability assessment, but PPWR compliance involves separate packaging-scope, material, chemical, labeling, documentation and other requirements. |
EN 13432 testing is commonly summarised through several core areas: biodegradation under controlled composting conditions, physical disintegration, limits on specified constituents and confirmation that the resulting compost does not show unacceptable ecotoxic effects. The exact test program and acceptance criteria should be checked against the applicable standard and certification scheme rather than reduced to a single marketing claim such as “biodegrades in 180 days.”
 |  |
2026 EU authority note: Regulation (EU) 2025/40 is now applicable, but the European Commission has stated that the existing EN 13432 standard can be used as guidance while updated harmonised compostability standards are developed. A certificate referencing EN 13432 should therefore not be presented as automatic proof of full PPWR compliance.
For a deeper Europe-focused discussion, see Bioleader®’s EN 13432 certification guide for bagasse and PLA tableware. Buyers dealing with current EU packaging requirements should also review the PPWR 2026 foodservice packaging checklist.
What Is ASTM D6400?
ASTM D6400 is a technical standard for plastics and products made from plastics that are designed to be aerobically composted in municipal or industrial facilities. As of September 2026, ASTM D6400-26 is the current active edition.
ASTM D6400 is frequently discussed together with BPI certification in North America, but the two terms are not interchangeable:
| Term | What It Actually Means |
|---|---|
| ASTM D6400-26 | A technical standard specification covering plastics and products made from plastics intended for controlled municipal or industrial aerobic composting. |
| BPI | A third-party certification organization and certification scheme. BPI uses ASTM D6400 as the base standard for its commercial compostability assessment and may apply other ASTM routes depending on product construction. |
| ASTM D6868 | A separate ASTM route relevant to eligible products where biodegradable plastic film or sheet is attached to a substrate such as paper or fibre. |
| ASTM D8410 | An assessment route BPI may use for eligible cellulosic-fibre-based substrates, subject to the scheme’s scope and exclusions. |
This distinction matters for molded fibre, bagasse and coated-paper packaging. Buyers should not automatically classify every fibre product as an “ASTM D6400 product.” The applicable test or certification route depends on the full construction of the finished item.
 |  |
Current edition check: If a supplier, specification or buyer document still refers only to ASTM D6400-23, ask whether the evidence, certification scheme or test program has been reviewed against the current ASTM D6400-26 edition. Do not assume that an older report becomes invalid automatically, but do verify what the current certification body or customer requires.
For buyers comparing broader compostability systems, Bioleader®’s BPI vs EN 13432 vs AS 4736 vs AS 5810 guide explains the difference between technical standards, certification schemes, commercial composting and home composting.
EN 13432 vs ASTM D6400: What’s the Difference?
| Buyer Question | EN 13432 | ASTM D6400-26 / North American Context |
|---|---|---|
| What is it? | European technical standard for packaging recoverable through composting and biodegradation. | ASTM technical standard for plastics and products made from plastics intended for municipal or industrial aerobic composting. |
| Main market context | Europe and European industrial-compostability certification schemes. | North America, especially commercial-compostability testing and certification programs using ASTM standards. |
| Is it a certification body? | No. | No. |
| Common third-party certification route | Certification schemes may include TÜV AUSTRIA OK compost INDUSTRIAL, DIN CERTCO or other applicable schemes. | BPI Commercial Compostability Certification is a major North American third-party route. |
| Does it cover home composting? | No. Home compostability requires separate evidence or certification. | No. ASTM D6400 is for controlled municipal or industrial composting. BPI now operates a separate home-compostability certification program. |
| Does it prove food-contact compliance? | No. | No. |
| Does it automatically cover all fibre products? | No. Product and packaging scope must be verified. | No. North American certification may use D6400, D6868 or D8410 depending on construction and scheme eligibility. |
| Current edition / status | EN 13432 remains an important reference; PPWR-related harmonised compostability standards are being updated. | ASTM D6400-26 is the current active edition. |
| Buyer verification priority | Check certificate issuer, scheme, exact product scope, formulation, thickness, colour, coating, print and current validity. | Check ASTM edition, certification program, BPI listing where applicable, exact item/SKU, construction and current certification status. |
Bottom line: EN 13432 and ASTM D6400 address related industrial-compostability questions, but they are not automatically equivalent, interchangeable or sufficient for every market. Export buyers should select the standard and certification route that matches the destination market, finished product and intended claim.
Do You Need Both Certifications for Export?
Not automatically. A buyer selling into both Europe and North America may need separate compostability evidence or certifications for each market, but the correct requirement depends on the product, claim, certification program, customer specification and applicable local rules.
| Export Scenario | Practical Buyer Approach |
|---|---|
| PLA cold cups for an EU program | Review the applicable EN 13432-related certification scope, PPWR requirements, food-contact documentation, product marking and destination-market rules. |
| PLA cups for a U.S. commercial-composting program | Review ASTM D6400-26-based evidence and, where required by the buyer, claim or jurisdiction, verify BPI commercial certification and the exact item listing. |
| Bagasse or molded-fibre food container | Do not assume ASTM D6400 is automatically the correct North American route. Verify the certification scheme and test route used for the actual fibre construction, additives and barrier system. |
| Paper packaging with a compostable polymer coating | Check the complete product construction. A North American certification program may use ASTM D6868 or another applicable route rather than treating the package as a simple D6400 plastic product. |
| Multi-market private-label program | Build a market-by-market document matrix instead of using one generic “global compostable certificate” statement. |
For buyers managing several countries, Bioleader®’s 2026 global compostable packaging regulations guide provides the broader regulatory context. For Europe specifically, national rules can also differ where EU law permits Member State measures; the updated Italy 2026 compostable packaging rule shows why EN 13432 references must be read together with the actual legal scope.
What Materials Can Be Certified?
Material name alone is not enough to determine certification. Compostability assessment depends on the complete finished product, formulation, thickness, additives, coatings, inks, adhesives, labels and other components.
| Material / Product Type | EN 13432 Context | ASTM / BPI Context | Buyer Warning |
|---|---|---|---|
| PLA plastic products | May be eligible for industrial-compostability certification when the finished product meets the applicable requirements. | ASTM D6400 is a core reference for eligible compostable plastic products; BPI may certify qualifying items. | PLA resin certification does not automatically cover every finished cup, lid, print or thickness. |
| Bagasse / molded fibre | Finished packaging may be assessed under an applicable industrial-compostability certification route. | Do not assume D6400 alone is the correct route; BPI may use different assessment paths for eligible fibre-based items. | Additives, barrier chemistry, PFAS controls and attached components must be checked. |
| Paper or fibre with compostable polymer coating | The complete package must be evaluated, not only the base paper. | ASTM D6868 may be relevant for eligible products with biodegradable plastic films or coatings attached to substrates. | “Paper” does not automatically mean plastic-free, recyclable or compostable. |
| Cornstarch-based products | Eligibility depends on the actual resin system and finished-product certification scope. | Eligibility depends on polymer formulation and the applicable certification route. | Cornstarch content does not automatically mean plastic-free or home compostable. |
| PET or conventional PP products | Not industrial-compostable merely because they are recyclable or used in food packaging. | Not ASTM D6400 compostable products simply because they are plastics. | Do not mix recyclability claims with compostability claims. |
| Oxo-degradable plastics | Should not be presented as EN 13432 compostable packaging on the basis of oxo-degradation. | Should not be presented as ASTM D6400 compostable based on oxo-degradation. | Fragmentation is not equivalent to certified compostability. |
For PLA applications, Bioleader®’s PLA material guide explains the polymer itself, while the compostable PLA cups category shows the cold-drink product application. PLA cups should generally be treated as cold-use packaging unless the specific product and test evidence support another temperature range.
Buyers comparing multiple compostable product families can also review Bioleader®’s compostable tableware and packaging solution, then request product-specific documentation for the selected SKU.
Can You Self-Declare Compliance?
There is no single yes-or-no answer that applies to every market, claim and certification scheme. EN 13432 and ASTM D6400 are technical standards; they do not themselves issue certificates or certification logos.
Buyers should distinguish three different statements:
- “Tested according to a standard” — this should be supported by valid test evidence covering the relevant product and test scope.
- “Complies with EN 13432 / ASTM D6400” — this claim should be supported by appropriate technical evidence and must be lawful in the destination market.
- “Certified by TÜV AUSTRIA / DIN CERTCO / BPI” — this requires a valid certification issued under that organization’s scheme and permission to use the relevant certification mark.
Certification-mark rule: Passing a test or receiving a laboratory report does not automatically grant permission to use a third-party certification logo. The supplier or brand should verify the current certificate, licensed mark, product listing and labeling rules of the certification scheme.
BPI, for example, maintains a searchable certified-product catalogue down to product or item level. For procurement, this type of listing is more useful than accepting a generic statement that a supplier “has BPI.”
Bioleader® publishes available third-party documents by product category on the Certificates & Test Reports page. Document availability and applicability vary by material, specification, production site and destination market, so buyers should confirm the exact product scope before using a certificate in artwork, tenders or regulatory files.
Is Home Composting Covered?
No. EN 13432 and ASTM D6400 should not be treated as home-compostability standards. Industrial or commercial composting operates under managed conditions that differ from household compost bins.
| Claim | What Buyers Should Verify |
|---|---|
| Industrial / commercially compostable in Europe | Applicable EN 13432-related certification scheme, finished-product scope and local industrial-composting route. |
| Home compostable in Europe | A separate home-compostability certification route, such as an applicable TÜV AUSTRIA OK compost HOME scheme or other recognised evidence where relevant. |
| Commercially compostable in North America | Applicable ASTM-based commercial-compostability evidence and certification, such as BPI where required or specified. |
| Home compostable in North America | Separate home-compostability evidence. BPI now operates a Home Compostability Certification Program in addition to its commercial certification. |
| Home compostable in Australia | AS 5810-related verification rather than assuming that commercial-compostability evidence is sufficient. |
Claim boundary: “Industrial compostable,” “commercially compostable” and “home compostable” are not interchangeable marketing terms. The disposal instruction should match the certification scope and actual waste infrastructure.
Compostability Does Not Mean Food-Contact Compliance
A compostability certificate answers an end-of-life question. It does not by itself prove that a cup, bowl, tray, lid or container is suitable for contact with food.
For export buyers, compostability and food-contact compliance should be managed as separate evidence streams:
| Evidence Area | Typical Question | Examples of Separate Documentation |
|---|---|---|
| Compostability | Can the finished product meet the applicable industrial or home-compostability criteria? | EN 13432-related certification, ASTM-based test/certification evidence, BPI listing, home-compostability certificate where applicable. |
| Food contact | Is the material and finished article suitable for the intended food, temperature and contact time? | Applicable EU food-contact documentation, FDA-related evidence, LFGB testing or other market-specific records. |
| Chemical restrictions | Does the package comply with applicable PFAS, heavy-metal or restricted-substance rules? | Product-specific declarations and analytical reports. |
| Packaging regulation | Does the complete package satisfy current packaging, labeling, recyclability and technical-documentation requirements? | PPWR or other destination-market packaging documentation. |
This distinction is particularly important in the EU. Under PPWR, compostable packaging can still be subject to separate food-contact and packaging requirements. A certificate should therefore be treated as one part of the compliance file rather than a universal approval document.
How Do These Standards Support Plastic Bans and Compostable Claims?
EN 13432 and ASTM standards are often referenced by certification schemes, procurement specifications and laws governing compostable claims, but the exact legal effect varies by country, state, product category and claim.
Buyers should avoid three common shortcuts:
- Do not assume EN 13432 is automatically mandatory for every package sold in Europe. The legal requirement depends on the product, claim and applicable EU or national rule.
- Do not assume ASTM D6400 is automatically mandatory for every product sold in the United States or Canada. State rules, local programs, customer specifications and certification requirements differ.
- Do not assume certification guarantees acceptance by every composting facility. Local collection and facility acceptance remain separate practical questions.
For current EU procurement, the PPWR 2026 buyer checklist should be used together with product-specific compostability evidence. For multi-market programs, review Bioleader®’s global compostable packaging regulations guide.
How Should Buyers Verify an EN 13432 or ASTM Compostability Certificate?
The strongest procurement check is certificate-to-SKU matching. A supplier may genuinely hold a compostability certificate while the exact item being quoted sits outside that certificate’s scope.
Buyer Verification Checklist
- Certificate holder: Is the named company the manufacturer, material supplier, licensee or another entity?
- Certification scheme: Which organization issued or manages the certification?
- Standard and edition: Does the document reference the correct standard and, where relevant, the current edition?
- Product name and SKU: Is the exact item or controlled product family included?
- Material structure: Does the certificate cover the same resin, fibre, coating, laminate and component structure?
- Thickness or weight: Are thickness, coating weight or other dimensional limits specified?
- Colour: Does the certification cover natural, white, black or other supplied colours?
- Printing and ink: Is the printed version covered, or only an unprinted base product?
- Lids and accessories: Are separate lids, labels, sleeves or windows included in the scope?
- Production site: Does the approved manufacturing unit match the actual supply chain?
- Current status: Is the certification valid and searchable in the certification body’s current records where a public database exists?
- Claim wording: Does the planned “compostable,” “commercially compostable” or “home compostable” claim match the certificate?
Bioleader® Evidence-Mapping Approach
Based on Bioleader®’s experience supporting international foodservice packaging buyers, certificate review should begin with the actual SKU rather than the certification logo. For PLA cups, bagasse products, coated paper packaging, cornstarch products and compostable cutlery, the material structure and available documentation can differ substantially.
Bioleader®’s Certificates & Test Reports page groups available evidence by product family, including compostability, food-contact, PFAS-related and factory-system documents. Buyers should request the applicable current document set for the selected product before confirming bulk production or compliance artwork.
EN 13432, ASTM D6400 and Bioleader® Product Selection
The right product should be selected by food application first and certification pathway second. A certificate should support an appropriate product; it should not be used to force every application into the same material.
| Bioleader® Product Family | Typical Application | Compostability Verification Focus |
|---|---|---|
| PLA clear cups | Cold drinks, iced coffee, juice, smoothies and bubble tea | PLA product construction, cup/lid scope, industrial-compostability certificate, food-contact evidence and cold-use conditions. |
| Sugarcane bagasse tableware | Hot meals, clamshells, plates, trays, bowls and takeaway food | Finished-fibre product scope, barrier/additive system, PFAS evidence, food-contact suitability and applicable compostability route. |
| Paper food packaging | Cups, soup bowls, salad bowls and food boxes | Paperboard plus PE, PLA, aqueous or other barrier structure; do not infer compostability from paper appearance alone. |
| Cornstarch tableware | Plates, bowls, clamshells and selected foodservice items | Actual resin system and finished-product certificate; cornstarch content alone does not prove plastic-free or home-compostable status. |

Final Takeaways for Export Buyers
- EN 13432 and ASTM D6400 are technical standards, not certification bodies.
- ASTM D6400-26 is the current active edition as of September 2026.
- BPI is a certification scheme, not another name for ASTM D6400.
- Different product constructions may use different ASTM assessment routes. Fibre and coated-paper products should not automatically be treated as simple D6400 plastic items.
- EN 13432 remains relevant in Europe, but it should not be represented as automatic proof of full PPWR conformity.
- Industrial compostability does not prove home compostability.
- Compostability does not prove food-contact safety, PFAS compliance or universal market access.
- The certificate must match the finished SKU. Holder, product, material, thickness, coating, print, colour, production site and validity should be checked.

Frequently Asked Questions
What is the main difference between EN 13432 and ASTM D6400?
EN 13432 is a European technical standard for packaging recoverable through composting and biodegradation, while ASTM D6400 is an ASTM standard for plastics and products made from plastics intended for aerobic composting in municipal or industrial facilities. They address related industrial-compostability questions but are not automatically interchangeable.
What is the current version of ASTM D6400?
As of September 2026, ASTM D6400-26 is the current active edition. Buyers reviewing older reports or specifications that cite D6400-23 should confirm whether the document remains acceptable to the relevant certification body, customer or jurisdiction.
Is BPI the same as ASTM D6400?
No. ASTM D6400 is a technical standard. BPI is a third-party certification organization and certification scheme. BPI uses ASTM D6400 as the base standard for commercial compostability assessment and may apply other ASTM routes depending on the product construction.
Does ASTM D6400 mean a product is home compostable?
No. ASTM D6400 addresses controlled municipal or industrial aerobic composting. A home-compostability claim requires separate applicable evidence or certification. BPI also operates a separate Home Compostability Certification Program.
Does EN 13432 certification prove full PPWR compliance?
No. EN 13432-related evidence can support an industrial-compostability assessment, but PPWR compliance involves additional requirements that depend on the packaging type, material, use and applicable date. The European Commission’s 2026 guidance states that the existing EN 13432 standard can be used as guidance while updated harmonised compostability standards are developed.
Does compostability certification prove food-contact safety?
No. Compostability and food-contact compliance are separate evidence areas. Buyers should verify food-contact suitability for the actual material, food type, temperature and contact conditions in the destination market.
Can one certificate cover every product made from the same material?
Not automatically. Certification scope may depend on the product, formulation, thickness, colour, coating, printing, components and manufacturing site. Buyers should confirm that the exact SKU or controlled product family is included in the current certificate.
Do bagasse products automatically fall under ASTM D6400?
No. Bagasse and other cellulosic-fibre products should not automatically be classified as ASTM D6400 products. The applicable North American test and certification route depends on the complete product construction and the certification scheme used.
