Which bio-based textiles qualify for USDA BioPreferred labeling?

What to take away

• USDA BioPreferred bio-based textiles split into two groups: complex products that need at least 25 percent biobased content and listed categories with their own higher floors.
• The program is run by the USDA, not a private certifier, and it produces two labels plus a searchable catalog of certified items.
• Apparel, towels, bedding and other textile categories can qualify, but each carries a specific minimum biobased content threshold.
• BioPreferred labeling and BE disclosure reporting are different obligations that draw on the same biobased content number.
• The label says nothing about organic farming, dye chemistry, worker conditions or biodegradability, so pair it with the standards that cover those.

What the USDA BioPreferred Program labels and who administers it

The USDA BioPreferred Program is a federal procurement and labeling effort run by the U.S. Department of Agriculture. It has two parts. One is a purchasing preference that directs federal agencies and their contractors toward biobased products. The other is the voluntary label that manufacturers can put on qualifying goods, including textiles.

The program's own overview describes the label categories and the way products are registered. You can read that framing at the program overview. The short version: a product either falls into a designated category with a published minimum biobased content, or it is assessed as a complex product against the general floor.

The label itself is not a certification in the sense that GOTS or OEKO-TEX are. No auditor visits your mill. You submit biobased content test results from an approved method, the USDA reviews the application, and accepted products go into a public catalog. The agency does not test the fiber itself.

That structure matters for a US product developer. You are making a claim to a federal agency, and the claim rests on laboratory analysis of the biobased carbon share, not on a supply chain audit. If your supplier cannot produce that test data, the label is out of reach regardless of how the fiber was grown.

Bio-based material, in the definition used across this space, means material derived from living organisms, plants, animals or microorganisms, as opposed to fossil feedstocks. The background definitions and examples are worth reading before you argue about whether a particular polymer counts.

Minimum biobased content thresholds by product category

Biobased content is measured as the share of total organic carbon in the product that comes from renewable biological sources, using radiocarbon analysis under ASTM D6866. That is the number the USDA compares against a threshold. It is not a weight percentage and not a recycled content figure.

For products that fall into a designated category, the threshold is set for that category and published. For products that do not, the default floor for a complex product applies. The USDA publishes the category list and the thresholds that go with it at the product categories page.

The table below shows how the floors work in practice for textile-adjacent goods. Check the current published figure for your exact category before you build a claim, because the USDA has revised thresholds over time.

Product situation	Minimum biobased content	Notes for textile developers
Complex product, no designated category	25 percent	Applies to assembled goods such as a finished garment with mixed inputs
Designated category with a published floor	Varies by category	Towels, bedding and similar items sit here
Textile product with a high biobased input	Category floor, often above 25 percent	Cotton, wool, hemp and bio-based synthetics can clear it
Product with significant fossil-based content	Below floor	Blends with polyester or nylon usually fail unless the biobased share is high
Packaging and intermediate materials	Separate category rules	Do not assume a textile threshold carries over

Two practical points. First, a 100 percent cotton towel and a 60/40 cotton-poly blend are not judged the same way, because the blend dilutes the biobased carbon share. Second, the threshold applies to the product as submitted, so the unit of analysis you declare determines whether you pass.

If you are still deciding what to put in the product, work through the routes for bio-based fibers and compare cost, supply reliability and how each one behaves under radiocarbon testing.

Which textile categories realistically qualify for BioPreferred labeling

Textile categories that can realistically qualify share one trait: a high share of the product's organic carbon comes from a plant or animal source. That is the whole test. Everything else is paperwork.

Apparel made from cotton, wool, hemp, linen or lyocell can clear the floor if the blend is clean enough. So can garments built on viscose from certified feedstock or a bio-based polyester analogue. Towels, bedding, blankets, upholstery fabric, nonwoven wipes and geotextiles are the categories most often seen in the catalog.

Blends are where projects stall. A jacket shell that is 55 percent cotton and 45 percent conventional polyester will usually land below a category floor, because the fossil carbon counts against you. Swapping the polyester for a bio-based version changes the arithmetic, but only if that material's own biobased content is documented.

Trims, zippers, buttons, elastics and adhesives are the quiet failure point. A garment can be 90 percent cotton by weight and still miss a threshold once the fossil-based trims are counted in the submitted product. Decide early whether you are labeling the textile or the finished good, because the two answers give different numbers.

Finishing chemistry matters less than people assume, since the metric is carbon origin rather than toxicity. A conventionally dyed cotton fabric can qualify. That is also why the label should not be read as a chemical safety claim.

Before you build a program around a single fiber, run the checks in the before you commit list against your actual supply base, especially documentation and volume.

Reading the BioPreferred catalog for textile entries

The catalog is the practical tool. It is a searchable list of products the USDA has accepted, and each entry shows the biobased content figure that was approved. You can browse it at the searchable catalog.

Use it three ways. First, to check whether a supplier's product is already listed, which saves you an application. Second, to see what biobased content figures are typical in your category, which gives you a realistic target. Third, to see which competitors hold a label, which tells you whether the claim is differentiating in your market.

A catalog entry is not a guarantee of supply. The listing tells you the product passed review at a point in time. It does not tell you the mill still runs that construction, that the fiber source has not changed, or that the price works for your program.

Read entries with the same skepticism you would apply to any database. Confirm that the listed product matches the specification you intend to buy, not just the brand name. Ask for the current test report behind the listing.

For a broader audit of what a label does and does not prove, the textile dyes and finishes checklist is a useful companion to catalog browsing.

BE disclosure rules and how they interact with a label claim

BE disclosure is the reporting side of the same statute. Federal agencies and their contractors must report their purchases of biobased products, and the program rules covering those obligations and the labeling claims sit together at the BE disclosure rules.

For a private brand, BE disclosure is usually not a direct obligation. It matters indirectly, because it drives federal demand for labeled products and because the same biobased content figure underpins both the label and the reporting. One test result, two uses.

Do not conflate the two in marketing copy. A BioPreferred label is a statement about biobased carbon content that the USDA has reviewed. It is not a statement that a product is sustainable, compostable or low impact. The FTC Green Guides govern how you may characterize environmental benefits, and a label claim does not immunize adjacent claims.

If you sell to federal buyers, the label can be a procurement advantage. If you sell only to consumers, its value is the third-party review behind the number, which is more defensible than a self-declared biobased percentage.

Keep the test report, the application and the approved content figure on file. If a claim is challenged, that file is your evidence.

Where BioPreferred stops and other fiber standards begin

BioPreferred answers one question: how much of the carbon in this product came from recent biological sources. It does not answer where the fiber was grown, how the field was managed, what chemistry was used downstream, or how workers were treated.

Those questions belong to other schemes. GOTS covers organic fiber content and processing criteria. OEKO-TEX Standard 100 addresses harmful substances in finished textiles. Cradle to Cradle Certified looks at material health and circularity.

The Higg Index, run through the Sustainable Apparel Coalition, assesses value chain impacts. ASTM Committee D13 writes many of the textile test methods underneath all of them.

The regulatory layer is separate again. The FTC Green Guides constrain environmental marketing claims. The CPSC enforces fiber content and flammability rules for apparel and home textiles. US Customs and Border Protection governs country of origin and import labeling. None of these overlap with the biobased content threshold.

So a realistic stack for a US brand looks like this: BioPreferred for the biobased content claim, a fiber standard for sourcing and processing, a chemical standard for finished goods, and correct origin and fiber content labeling for customs and consumer disclosure.

A short checklist before you file:

• Confirm your product falls in a designated category or is assessed as a complex product.
• Get ASTM D6866 biobased content results from an accredited lab.
• Check the current published threshold for that category.
• Decide whether you are submitting the textile or the finished good, and count trims accordingly.
• Verify the supplier's fiber source has not changed since the test.
• Confirm your other marketing claims comply with the FTC Green Guides.
• Check fiber content and origin labeling against CPSC and CBP requirements.

If you are comparing how these standards fit together across a product range, the bio-based fibers example guide walks through the overlaps. And if the fiber decision is still open, the natural textile fibers overview covers what each one delivers in practice.

Common questions

Does a BioPreferred label mean a textile is biodegradable? No. The label reports biobased carbon content only. Biodegradability is a separate claim and falls under FTC Green Guides scrutiny, which requires competent and reliable evidence for the specific disposal environment.

What biobased content does a finished garment need? If it has no designated category, treat it as a complex product and expect a 25 percent floor. If it fits a designated category, the published threshold for that category applies and may be higher.

Can a cotton and polyester blend qualify? Sometimes. The fossil carbon in the polyester lowers the biobased share, so a high cotton content with documented bio-based polyester can pass while a conventional 50/50 blend usually will not.

Is BioPreferred the same as BE disclosure? No. The label is voluntary and product-facing. BE disclosure is the federal purchasing and reporting obligation. They share the same underlying biobased content measurement.

Who tests the biobased content? An accredited laboratory using radiocarbon analysis under ASTM D6866. The USDA reviews the submitted result rather than running its own test on your product.

Does the label cover worker conditions or farming practices? No. Those sit with GOTS, OEKO-TEX and similar schemes. BioPreferred is a single-attribute claim about carbon origin.
