USDA Certified Biobased is a real, third-party-verified label — but it does not mean a product is vegan, organic, or plant-based. It only certifies the percentage of renewable "biobased" carbon in a material, measured against total carbon content. That carbon can legally come from animal or marine sources as well as plants, so a Certified Biobased label alone never proves cruelty-free or vegan status. Here's exactly what the label on Coneli's own materials verifies, and what it doesn't.
What Is a USDA Certified Biobased Product?
The USDA Certified Biobased Product label was created under the BioPreferred Program, established by Section 9002 of the 2002 Farm Security and Rural Investment Act and administered by the U.S. Department of Agriculture. It identifies products that contain a certified amount of renewable, plant- or agriculturally-derived carbon, verified through independent third-party testing rather than a brand's own claim.
The program's own language is direct about what the label assures: that "the manufacturer's claims regarding the presence and the amount of biobased content are third-party tested and verified and strictly monitored by USDA." It's a single-attribute certification — it exists to answer one question (how much of this material's carbon is renewable?), not a general "is this sustainable?" seal of approval.
How Is Biobased Content Actually Measured?
Biobased content is calculated as the ratio of "new" organic carbon — carbon from recently grown agricultural, forestry, or aquatic material — to the total organic carbon in the product, excluding water and inorganic carbon. Labs measure this using ASTM D6866, a radiocarbon-dating-based testing standard that is cited directly in U.S. federal law and used internationally.
The program currently manages 141 designated product categories, each with its own minimum required percentage for federal purchasing preference. For any product category without a designated minimum — which covers most plant-based leather alternatives — the baseline requirement is at least 30% biobased content. Materials like Desserto cactus leather and OLEATEX olive leather, both used in Coneli products, are independently disclosed at 65–80% biobased content, well above that 30% floor.
USDA Certified Biobased vs. Vegan vs. Organic: What Each Term Actually Proves
These four labels get used almost interchangeably in fashion marketing, but they certify completely different things. None of them substitutes for another.
| Label | What it actually verifies | Can it include animal-derived material? | Who verifies it |
|---|---|---|---|
| USDA Certified Biobased | % of renewable carbon vs. total carbon (ASTM D6866) | Yes — biobased carbon can come from animal or marine sources, not just plants | USDA-approved third-party labs |
| Vegan | No animal-derived ingredients or materials at all | No, by definition | Varies — no single federal standard in the U.S. |
| USDA Organic | Grown/processed without synthetic pesticides, fertilizers, or GMOs | N/A — a farming/processing standard, not a material-origin standard | USDA-accredited certifying agents |
| "Eco-friendly" / "sustainable" | Nothing specific — no legal definition or required verification | N/A | Self-declared by the brand |
The practical takeaway: a genuinely vegan, plant-based bag should be able to show you both a Certified Biobased percentage and a plant-based material name and supplier (Desserto, OLEATEX, Piñatex, Mirum, and similar are actual companies you can verify) — not one label standing in for the other.

How Does a Product Actually Get Certified?
The certification process is more involved than simply printing a badge on packaging:
- Pre-qualification — program staff review the product category before any testing begins.
- Third-party lab testing — samples go to an ASTM-approved laboratory, at roughly $500 USD per sample plus shipping.
- Verification — results are checked against the category's minimum threshold (or the 30% baseline for uncategorized products).
- Timeline — the full process generally takes about 90 days when a company responds promptly to each step.
- Renewal — certification isn't permanent. It lasts five years, after which the product must be re-tested and re-certified or it's removed from the public BioPreferred catalog.
That renewal requirement matters more than it sounds: it means a Certified Biobased claim from 2019 isn't automatically still valid today unless it's actually been renewed. If a brand cites the certification without a recent date, that's worth asking about.
Where This Label Shows Up on Coneli Products
Coneli uses two plant-based leather suppliers whose materials carry independently disclosed biobased content: Desserto® cactus leather (used in the Belt's Black, Green, and Beige editions, and in the Fanny Pack) and OLEATEX® olive leather (used in the Belt's Espresso, Brown, and Taupe editions). Both are disclosed at 65–80% biobased content — well above the 30% baseline threshold, and above what many uncertified "cactus leather" or "vegan leather" products on the market disclose at all.
This is also why Coneli names its material suppliers directly rather than using the generic term "cactus leather" or "vegan leather" alone. A named, traceable supplier is something you can look up and verify; an unnamed blend is not. For the deeper material-by-material breakdown, see what Desserto cactus leather actually is and what Oleatex actually is.
Why "Higher Biobased %" Doesn't Automatically Mean "Better"
One nuance worth being honest about: the USDA program itself states that a higher biobased percentage doesn't automatically indicate superior performance, safety, or environmental impact. Biobased content measures renewable carbon origin — it says nothing about durability, water resistance, how a material ages, or its full manufacturing footprint. It's one honest data point, not the whole picture. That's exactly why it's worth pairing with independent facts about durability and care, like in our plant-based leather care guide.
Frequently Asked Questions
Does USDA Certified Biobased mean a product is vegan?
No. Biobased content can legally come from animal or marine sources, not only plants. Certified Biobased and vegan are separate claims that happen to overlap in materials like Desserto cactus leather and OLEATEX olive leather, but the label itself doesn't guarantee no animal-derived content.
Is USDA Certified Biobased the same as USDA Organic?
No. USDA Organic certifies farming and processing methods (no synthetic pesticides, fertilizers, or GMOs). USDA Certified Biobased certifies the percentage of renewable carbon in a finished product. A material can be one, both, or neither.
How is biobased content tested?
Using ASTM D6866, a radiocarbon-based testing standard that measures the ratio of new organic carbon to total organic carbon in a sample. Testing is done by approved third-party labs, not self-reported by the brand.
What's the minimum biobased percentage required for certification?
At least 30% for product categories without their own designated minimum, which covers most plant-based leather alternatives. The program manages 141 designated categories in total, each with its own threshold.
Does the certification expire?
Yes — every five years. After that, the product must be re-tested and re-certified to remain listed in the official BioPreferred catalog.
What materials does Coneli use that carry this certification?
Desserto® cactus leather (Belt in Black, Green, and Beige; the Fanny Pack) and OLEATEX® olive leather (Belt in Espresso, Brown, and Taupe), both independently disclosed at 65–80% biobased content.
