Quick Answer
BPI Certification is a third-party compostability certification used in the United States and Canada to verify that finished products meet ASTM D6400 or ASTM D6868 standards for industrial composting.
What does “BPI compostable” mean?
It means the finished product is certified and listed in the official BPI database.Is BPI home compostable?
No. BPI applies only to industrial composting systems.How do I verify a BPI certified product?
Search the product or company in the BPI certified products database.
When you see “BPI Certified Compostable,” it means the finished product is certified to meet ASTM D6400 or ASTM D6868 and is intended for industrial composting programs in the U.S. and Canada. This page explains what the certification means, how to verify it, and how to use it correctly.
What Is BPI Certification?
BPI Certification is a third-party program run by the Biodegradable Products Institute. BPI checks whether a product can safely break down in commercial compost systems. Certified products such as commercial compostable trash bags are widely accepted by industrial composting facilities across the United States. These systems operate at high temperatures and have controlled airflow and moisture. They are very different from a backyard compost bin.
To become BPI certified, a product must meet the rules of:
-
ASTM D6400 – compostable plastics
-
ASTM D6868 – compostable coatings, paper liners, and packaging
BPI also checks the product’s ingredients and reviews its labeling. When a product passes all steps, it earns the BPI Certified Compostable Mark. Composting facilities in the U.S. use this mark as a trusted signal. https://bpiworld.org/Certification
What Does “BPI Compostable” Mean?
“BPI compostable” means the finished product is certified by the Biodegradable Products Institute and listed in the official BPI database for industrial composting.

“BPI compostable” means the finished product (not only the resin) has passed ASTM compostability tests and is approved by BPI for industrial composting programs in North America.
It does NOT mean the item will break down in landfills, oceans, or every backyard compost bin.
If you are buying compostable bags for a municipal or food waste program, this label is often the fastest way to reduce contamination risk.
Many programs also follow strict sorting rules, so it helps to understand BPI certified compostable products within real composting streams.
If you are unfamiliar with the term, this guide explains what does BPI compostable mean and how certification applies to finished products.
Standards Behind BPI Certification (ASTM D6400 & ASTM D6868)
These two standards are the backbone of the BPI program. They are technical documents, but I can summarize them simply.
ASTM D6400
This standard applies to compostable plastics. It measures how fast the plastic biodegrades, how well it breaks apart, and whether it harms the finished compost.
ASTM D6868
This standard applies to items made of paper or fiber that include a compostable coating or film. It makes sure the coating also meets composting rules.
Together, they provide clear criteria for industrial compostable certification in North America.
Key Requirements for BPI Certification
For a product to earn the BPI certified compostable label, it must pass several scientific tests. These tests are done by independent labs.
1. Biodegradation
The material must convert into carbon dioxide, water, and biomass. It cannot remain as microplastic. This process must follow the curve defined in ASTM D6400.
2. Disintegration (84 Days / 12 Weeks)
In a commercial composting system, the item must break into small fragments. After 12 weeks, no large pieces should remain. This is important for compost quality.
3. Ecotoxicity and Plant Safety
The finished compost must support healthy plant growth. It must not introduce harmful chemicals or toxic byproducts into the soil.
4. Heavy Metals and Hazardous Substances
BPI enforces limits on metals like lead, cadmium, and mercury.
In recent years, BPI also added rules that restrict PFAS and other chemicals found to be harmful in composting systems (source: BPI policy update, 2023–2024).
5. Ingredient Review and Labeling
BPI reviews every additive, coating, and ink used in the product. The label must follow BPI’s style guide so composters can quickly identify certified items.
These requirements make BPI one of the most reliable industrial compostability certifications in North America.
Why BPI Certification Matters for Businesses
Your customers, waste haulers, and composting facilities need clear and honest labeling. BPI certification helps solve several real-world problems:
Avoiding greenwashing
Many products claim to be “biodegradable.” Without testing, this claim is unreliable.If you’re unsure why “biodegradable” claims often fail compliance, start with this simple guide on BPI certification and the compostable standards behind it.Accepted by composting facilities
Many U.S. municipal programs only accept BPI certified compostable bags and packaging.Meeting retailer and food service requirements
Large food chains and supermarkets often require suppliers to use certified compostable packaging in their organics programs.Supporting sustainability goals
Certified products help move food scraps and compostable packaging away from landfills and into industrial compost systems.
For companies selling compostable bags, liners, and packaging, BPI certification is not a bonus. It is essential.
Composting facilities rely on BPI certification because it helps them keep contamination low and maintain high-quality compost. Clear labeling reduces sorting problems and prevents non-compostable plastics from entering the system.
When you see a product marked with BPI Certified Compostable, it means something very specific.
The product has been tested under strict rules to confirm it can break down in an industrial composting facility.
As someone who works with compostable materials every day, I want to explain what this certification really means and how you can use it with confidence.
For procurement teams, the biggest risk is not performance—it’s compliance and acceptance. Choosing certified products helps reduce labeling disputes and contamination issues in organics streams. If you source packaging for distribution programs, you can also review our guide to certified compostable bags for North America.
BPI Certification vs Other Compostability Standards
BPI certification is mainly used for industrial composting programs in the U.S. and Canada. If you sell into other regions, you may also need additional compostability standards—such as EN 13432 for the EU, AS4736 for Australia industrial composting, or OK Compost HOME/INDUSTRIAL for specific labeling and acceptance requirements.
Here is a simple comparison to help you understand where BPI fits among global certifications:
| Standard | Region | Compost Type | Use Case |
|---|---|---|---|
| BPI Certification | USA & Canada | Industrial composting | North America market |
| EN 13432 | Europe | Industrial composting | EU export |
| OK Home Compost | Global | Home composting | Light packaging |
| AS4736 / AS5810 | Australia | Industrial / Home | AU / NZ organics programs |
Each certification is designed for a specific region and compost system.
If you sell globally, you may need more than one certification.

How to Apply for BPI Certification (Step-by-Step Guide)
BPI certification relies on recognized ASTM test methods, including the ASTM D6400 compostable standard, to evaluate industrially compostable plastic products.
Getting a product certified by BPI involves several scientific evaluations and documentation checks.
Here is the complete application process:
Step 1 — Prepare Product Documentation
You must provide:
- Full material composition (PLA/PBAT/Starch ratios)
- Additive, colorant, and ink disclosures
- Safety Data Sheets (SDS)
- Product drawings / film structure
- Intended end-use (bags, liners, packaging, mailers, etc.)
BPI requires 100% ingredient transparency before testing begins.
Step 2 — Pre-Screening Review by BPI
BPI reviews material safety and ingredient compliance.
If any chemical exceeds limits (such as PFAS, heavy metals), the product cannot enter certification testing.
Step 3 — Laboratory Testing (ASTM D6400 or D6868)
Testing must be conducted by a BPI-approved independent laboratory, which evaluates:
- Biodegradation curve
- Disintegration (84-day breakdown test)
- Ecotoxicity (plant growth test)
- Heavy metal limits
- Chemical safety
Testing typically takes 90–180 days depending on the product.
Step 4 — BPI Technical Review
After the lab submits test data, BPI performs:
- A technical audit
- Ingredient review
- Labeling review
- Packaging inspection
Step 5 — Approval & Certificate Issuance
When all requirements are met, BPI issues:
- Certificate Number
- Approved Products List
- Logo Usage Authorization
- Validity Period Information
Products must be renewed every 3 years, or earlier if the formula changes.
Step 6 — Listing on the BPI Public Database
Once approved, the product becomes publicly searchable on the BPI official website — a key requirement for waste facilities and retailers.
How to Verify a BPI Certified Product
Online and on Reddit, I notice many people confused by labels. Some products look “green,” but they are not certified. Here is a clear way to check:
1. Search the BPI Official Database
Go to BPI’s website and type the product name or company name.
If it is not listed, it is not certified.
2. Check the Certificate Number
A real BPI certified compostable product will include a valid certificate number. This number should match the database entry.
3. Look for the Correct BPI Logo
The logo must match BPI’s approved format. If it looks altered or incomplete, treat it as a red flag.
4. Know the Difference: Resin Certification vs Product Certification
Sometimes a raw material resin is certified, but the finished product is not.
A bag, cup, or film must be certified as a final item, not only by material.
5. Watch for Greenwashing
Claims like “earth-friendly,” “oxo-biodegradable,” or “biodegradable plastic” do not guarantee compostability.
By following these steps, you can avoid false claims and choose trustworthy compostable packaging.
You can verify any certified item through the official BPI Product Database:

Correct Disposal of BPI Certified Products
A BPI certified product is meant for industrial composting, not a backyard compost pile. The temperatures in home compost are usually too low to meet ASTM conditions.
To dispose of certified items correctly:
Place them in your local organics or food waste bin
Check whether your city accepts compostable packaging
Do not put them in recycling bins
Do not send them to landfill unless you have no composting option
Using the right bin keeps compost free from contamination and protects the composting system.
For organics collection programs, many buyers choose BPI certified compostable bags designed for clean sorting and stable performance.

Example:
- PBAT ratio too high
- PLA crystallinity causing slow biodegradation
2. Excessive thickness
If the bag is too thick, it may not disintegrate within 84 days.
3. Toxicity or chemical safety issues
Including:
- Heavy metals above limits
- Non-compliant inks or pigment
- Additives failing plant growth tests
4. Incorrect or incomplete documentation
This is one of the most common reasons manufacturers fail.
5. Misuse of the BPI logo
If labeling violates guidelines, certification can be suspended.
6. Resin certified ≠ finished product certified
Many companies misunderstand this rule.
