What’s the Difference Between BPI and TÜV Certification?

If you’re buying compostable foodware, you’ve probably noticed that some products carry a BPI logo, some carry a TÜV logo (sometimes labeled “OK compost” or “Seedling”), and some carry both. The two certifications look superficially similar — both are stamps that a third party tested the product and confirmed it composts. But underneath, they reflect different standards, different testing facilities, different geographies, and different commercial realities. Choosing wrong can leave you with a product that’s technically certified but rejected by your local hauler, or pass over a product that would have worked beautifully because its sticker was from the “other” continent.

This piece walks through the differences in plain English. We’ll cover what each certification actually tests, where each one is recognized, what they cost producers, and how a buyer should think about whether to insist on one, the other, or both.

The Two-Sentence Summary

BPI (Biodegradable Products Institute) is the dominant North American compostable certification, built around the ASTM D6400 and D6868 standards, designed for industrial composting in North American climates and waste systems.

TÜV Austria (formerly Vinçotte) is the dominant European compostable certification, built around the EN 13432 standard, with sub-certifications for industrial composting (OK compost INDUSTRIAL), home composting (OK compost HOME), seawater (OK biodegradable MARINE), soil, and freshwater environments.

Both certifications confirm a product will biodegrade under their target conditions and won’t leave toxic residues. They are not interchangeable, but they overlap significantly on the underlying chemistry.

What Each Certification Actually Tests

Most people assume “compostable” means “it disappears.” The certification standards define it more rigorously. Both BPI and TÜV require four things to be demonstrated.

Disintegration. The product, when fed into a composting system under standard conditions, must physically break apart into pieces smaller than 2mm within a defined time. BPI/ASTM D6400 requires this within 12 weeks. TÜV/EN 13432 also requires it within 12 weeks for OK compost INDUSTRIAL. For OK compost HOME, the bar is harder: the product must disintegrate within 26 weeks at the lower temperatures typical of backyard composters.

Biodegradation. The product’s carbon must be converted to CO2 by microbial activity. Both standards require at least 90 percent of the carbon to be converted within 6 months under industrial conditions. For TÜV’s HOME certification, the 90 percent must happen within 12 months at lower temperatures.

Ecotoxicity. The finished compost (after the product breaks down) must support plant growth, demonstrating that no toxic residues were left behind. Both standards use similar plant-growth assays (typically with summer barley and cress, comparing growth in compost containing the test product against a control compost).

Heavy metals. The product must not exceed strict limits for arsenic, cadmium, chromium, copper, lead, mercury, nickel, selenium, and zinc. The limits are similar across both standards.

The crucial difference: TÜV’s HOME, MARINE, SOIL, and other sub-certifications test under additional conditions that BPI does not address. BPI is exclusively an industrial composting certification — its temperatures, microbial communities, and timeframes assume a commercial facility with controlled aeration and temperatures of 55-65°C.

Where Each Is Recognized

Geography is where the two certifications most starkly diverge.

BPI is the de facto standard in North America. Most commercial composting facilities in the United States and Canada that accept foodservice packaging require BPI certification before they will accept a product into their stream. Some facilities (notably Cedar Grove in Seattle, Recology in San Francisco, Republic Services in several markets) maintain “accepted” lists of products, and almost all entries on those lists carry BPI. Buyers selling into US foodservice — restaurants, schools, stadiums, theme parks, corporate cafeterias — typically need BPI to get their products through hauler approval and into back-of-house programs.

TÜV is the de facto standard in Europe. The OK compost INDUSTRIAL mark is recognized across the EU, the UK, and most of Asia-Pacific where compostable foodware regulations have been adopted. Many European retailers (Carrefour, Albert Heijn, Tesco, Lidl) require TÜV certification for own-brand compostable packaging. Brands selling into the EU will face EN 13432 compliance and TÜV recognition as the path of least resistance.

Australia, New Zealand, and Asian markets are more mixed. Australia has its own AS 4736 standard (similar to EN 13432) with the Australian Bioplastics Association (ABA) administering certification. New Zealand follows similar lines. Japan has its own GreenPla certification but increasingly accepts EN 13432 / TÜV documentation. China, India, and Southeast Asia are heterogeneous; commercial composting infrastructure is limited and certification preference depends on the specific buyer.

Dual certification is increasingly common for products sold internationally. Brands like World Centric, Eco-Products, Vegware, and Be Green Packaging often hold both BPI and TÜV certifications, which simplifies global distribution but adds cost — typically $8,000 to $25,000 per product family per certification, with annual fees.

Industrial vs Home Composting: The Most Confusing Difference

Here’s where buyers get tripped up. Both BPI and TÜV OK compost INDUSTRIAL are about industrial composting. They do not say the product will compost in your backyard pile. The temperature, moisture, and aeration of a home pile are different — usually lower temperatures, less consistent moisture, and slower microbial cycling.

If you want a product that will compost at home, you need TÜV OK compost HOME specifically. BPI does not offer a home-composting certification (this may change in coming years, but as of early 2026 it has not). Products carrying OK compost HOME include some Vegware items, certain BioPak ranges, several brands of compostable bags from BioBag and World Centric, and a growing number of European retail brands.

This matters most for consumer-facing products. A pack of compostable trash liners sold at retail might be carrying BPI — perfectly valid for the customer with curbside organics — but won’t reliably break down in a backyard tumbler. The retailer who sells those liners as “great for home composting” is technically misrepresenting the product. Reputable retailers now distinguish “industrial compostable” from “home compostable” on the shelf and in the packaging.

What the Certifications Don’t Cover

A few common misconceptions.

Certification doesn’t guarantee the product will compost in YOUR facility. Many commercial composting operations operate on shorter cycles than the 12-week certification window. A facility that turns its piles every 8 weeks may screen out anything that hasn’t disintegrated by then — including some certified compostables. This is a real and common issue, especially with thicker items like compostable cups, lids, and rigid containers. The hauler’s accepted-items list is the operational truth; certification is the entry ticket but not the guarantee.

Certification doesn’t address PFAS. PFAS (per- and polyfluoroalkyl substances) are intentionally added grease-resistant coatings on some compostable papers, fiber containers, and bagasse products. Both BPI (as of 2020) and TÜV (more recently) now require PFAS-free formulations for certification renewal, but older certifications and some grandfathered products may still contain them. If PFAS-free matters to your program — and increasingly it does, with state-level bans in California, Washington, Maine, Vermont, New York, Minnesota, Colorado, and others — confirm separately with the manufacturer.

Certification doesn’t tell you the product is high-quality. A BPI-certified compostable cup might still leak coffee after 20 minutes. A TÜV-certified compostable bag might still tear under a heavy garbage load. The certifications confirm end-of-life behavior, not in-use performance. Always test products under your actual operational conditions before committing to a large order.

Certification doesn’t make the product “biodegradable” in a generic sense. A common mistake is conflating “compostable” with “biodegradable in nature.” If you litter a BPI-certified compostable fork on a beach or roadside, it will not break down meaningfully — it needs the specific conditions of a composting facility. Some products with TÜV OK biodegradable MARINE certification will degrade in seawater, but BPI does not cover that scenario, and most foodservice products are not marine-certified.

Cost and Process for Producers

If you’re a manufacturer choosing between certifications, the practical considerations are:

Test cost. Both BPI and TÜV require third-party laboratory testing. Typical lab costs run $5,000 to $15,000 per product family, depending on the materials and the number of tests required (some product changes trigger retesting, some don’t).

Certification fees. BPI charges a one-time application fee plus annual maintenance fees that scale with company size, typically $3,000 to $20,000 per year for active certifications. TÜV’s structure is similar but generally slightly higher.

Timeline. Allow 6 to 12 months from test initiation to certification mark on packaging. Lab queues, especially for plant-growth assays that require seasonal lab schedules, can extend this.

Renewal. Both certifications require periodic renewal — typically every 3 to 5 years — and any reformulation of the product triggers retesting.

Geographic priority. If your primary market is North America, start with BPI. If your primary market is Europe, start with TÜV OK compost INDUSTRIAL. Add the other certification later if your distribution expands.

A Buyer’s Decision Framework

If you’re a buyer evaluating compostable foodware, here’s a simple decision tree.

Step 1: Where is the product being used? If you’re sourcing for North American foodservice, BPI certification is the baseline. If you’re sourcing for European, UK, or Australian markets, TÜV OK compost INDUSTRIAL (or AS 4736 for Australia) is the baseline.

Step 2: Will the product be composted commercially or at home? Almost always commercially for foodservice. Almost always at home for some consumer products like trash liners, dog waste bags, and tea bags. Match the certification to the destination. If a consumer product is going home with consumers, OK compost HOME is the relevant mark; BPI alone may not be enough.

Step 3: Does your local hauler accept the product? Don’t skip this. Call your hauler. Send them the spec sheet. Get their written confirmation that the product is on their accepted list. Certification is necessary but not sufficient.

Step 4: Is the product PFAS-free? Confirm separately. Don’t assume.

Step 5: Does the product perform under your conditions? Test before scaling. Hot soup, ice baths, freezer storage, microwave heating — whatever your actual use case is, test it.

Real Product Examples and Common Dual-Certification Patterns

A few concrete examples to ground the comparison.

World Centric — A US-based brand that holds BPI certification on most of its food containers, cutlery, and cups. Several lines also carry TÜV OK compost INDUSTRIAL to support distribution in Canada and select international markets. Some of its compostable bags carry OK compost HOME for retail distribution.

Vegware — A UK-based brand built primarily on TÜV/EN 13432 certification, including OK compost HOME on certain bag products. As Vegware expanded into US foodservice, it added BPI certification on its core foodservice ranges to qualify for North American hauler acceptance.

Eco-Products — A US foodservice brand with extensive BPI certification across cups, lids, containers, and cutlery. Some products carry both BPI and TÜV to support its growing international distribution into Latin American and European foodservice markets.

BioBag — A Norwegian brand with deep TÜV OK compost HOME certification on its trash and produce bags. BioBag has selectively added BPI certification on its North American foodservice bag lines.

The pattern is consistent: brands start with the certification closest to home market and add the second certification as they expand. The cost of dual certification is meaningful but justified by avoided market access friction — many international buyers and large foodservice contracts now require both, especially for products distributed across multiple continents.

Verifying a Certification Claim

Both BPI and TÜV maintain public databases of certified products. A real certification can be verified by looking up the product or company on the certifier’s website. If you can’t find a product on the certifier’s database, that’s a red flag.

BPI database: Available on the bpiworld.org website under the “Find Certified Products” tool. Search by company name, brand, or product type. The database returns the certification number, the product category, the certifier’s effective date, and any expiration date.

TÜV database: Available on the tuv-at.be website (TÜV Austria’s English site) under the “OK compost” section. Same fields, similar interface. The certification number on a TÜV mark is unique and tied to a specific product, manufacturer, and formulation.

If a supplier shows you a certification on a PDF but the product doesn’t appear in the database, ask for the certification number and look it up yourself. There are unfortunately knock-off marks circulating, and a quick database check is your protection.

Geographic Edge Cases

A few specific situations worth mentioning.

California — California’s SB 1335 (state agency food packaging requirements) and AB 1276 (foodware accessory restrictions) effectively require BPI certification for compostable foodware sold to state-funded operations and most municipal contracts. The state’s commercial composting infrastructure aligns with BPI.

New York City — NYC’s commercial organics regulations have specific accepted-product lists administered by the Department of Sanitation. BPI certification is required but not always sufficient — DSNY maintains its own approval process on top of BPI.

United Kingdom — Post-Brexit, the UK technically maintains its own packaging compliance system but in practice still recognizes EN 13432 / TÜV certification. UK supermarkets and foodservice operations almost universally specify TÜV OK compost INDUSTRIAL or HOME for own-brand compostables.

Germany — Germany was the original EPR market and has the most mature compostable certification infrastructure in Europe. The Seedling logo (administered by DIN CERTCO under EN 13432) is sometimes seen alongside or instead of OK compost, but both reference the same underlying standard.

Australia — AS 4736 (industrial) and AS 5810 (home) are the local standards, administered by the Australian Bioplastics Association. The ABA accepts TÜV/EN 13432 documentation in lieu of its own testing in many cases, but the ABA Seedling logo is what Australian retailers and councils look for on the package.

These geographic differences matter most for brands with international ambitions. A US brand expanding into the UK should add TÜV. A UK brand expanding into California should add BPI. The certification is a market access tool as much as a quality tool.

A Final Note on Marketing Claims

The compostable foodware industry has, historically, been loose with terminology. “Eco-friendly,” “biodegradable,” “plant-based,” “earth-friendly” — these terms are not regulated and don’t mean anything specific. Only “compostable” with a recognized certification (BPI, TÜV, ABA, etc.) has a defensible meaning. Buyers should ignore the marketing language and read the certification label.

If you want to browse certified compostable products organized by category, our compostable food containers and compostable cups pages list options with their certifications noted. When in doubt, request the certification document directly from the manufacturer — every legitimate certification carries a unique number that can be verified on the certifier’s public database.

For procurement teams verifying compostable claims, the controlling references are BPI certification (North America), EN 13432 (EU), and the FTC Green Guides on environmental marketing claims — these are the only sources U.S. enforcement actions cite.
