What does recycled polyester on a label mean? The FTC rule and the 12% market share

A recycled polyester label is a legal claim, not a style note. Under the FTC's environmental marketing guidance, a seller may call a product recycled only when its material was diverted from the waste stream, and a product that is only partly recycled needs a clear percentage by weight. The industry's own data shows the category is still small: about 12.0% of global polyester in 2024.

What the federal rule says

The text sits in 16 CFR 260.13, one section of the FTC's Green Guides, and it is short. Misrepresenting, directly or by implication, that a product contains recycled content is deceptive. Recycled content means recycled raw material, and also used, reconditioned or remanufactured components.

The rule then sets three tests. First, the material must have been recovered or diverted from the waste stream, either during manufacturing (pre-consumer) or after consumer use (post-consumer). Second, a marketer claiming pre-consumer material needs substantiation that the material would otherwise have been thrown away. Third, any stated percentage of pre- or post-consumer content needs substantiation of its own.

The rule is written for all products, so none of its examples is about a T-shirt. Several still map neatly onto clothing, and we say below which.

When a bare "recycled" label is not enough

The rule says an unqualified recycled claim is appropriate only when the entire product, apart from minor incidental parts, is recycled. If the garment contains only some recycled fiber, the marketer should say so clearly and prominently, with the percentage by weight. The FTC's summary page, dated October 2012, gives the pattern: a claim such as "Made from 30% recycled material".

Two of the rule's examples matter for fabric. One says scraps reused within the original manufacturing process would normally be reused anyway, so calling them recycled is deceptive. In a mill, that means trim waste fed straight back into the same line is not a recycled claim. Another says an annual weighted average of recycled fiber across suppliers, after accounting for fiber loss, can support a claim. That is how a brand can truthfully state a percentage across a mixed supply chain.

A further example covers symbols. A recycling symbol on its own likely implies both recyclability and full recycled content, so it needs qualification or substantiation. A looping arrows icon on a hangtag is therefore a claim, and not decoration.

What the market data shows

The best public count of how much of this material exists comes from Textile Exchange, a nonprofit that tracks fiber production. Its Materials Market Report, published in September 2025, covers 2024.

Polyester is the largest fiber in the world: about 78 million tonnes in 2024, or approximately 59% of global fiber production, up from 71 million tonnes (57%) in 2023. Recycled polyester production rose from around 8.9 million tonnes in 2023 to around 9.3 million tonnes in 2024.

But virgin polyester production rose more, from 62 to 68 million tonnes, so recycled polyester's share fell from around 12.5% to around 12.0%. More volume, smaller share. Across all fibers, the report puts recycled fibers at around 7.6% of the market in 2024, and says less than 1% of the global fiber market came from pre- and post-consumer recycled textiles.

Where the recycled polyester comes from

This is the part labels rarely mention. Textile Exchange reports that recycled polyester is still primarily made from plastic bottles (98%). Systems for polyester textile to textile recycling are in development but are estimated at only around 2% of all recycled polyester. Ocean or ocean-bound plastic is under 0.005%.

None of that makes a bottle-based garment false advertising. A bottle that would otherwise be waste can meet the diversion test in the rule. But it changes what the claim means. A jacket sold as recycled has usually not been made from old jackets, and the closed loop that the phrase can suggest is still in development.

The Green Guides also warn about trade-offs. Their summary notes that a green claim paired with recycled content may be deceptive if the environmental costs of using recycled content outweigh its benefits. The FTC does not tell sellers how to run that comparison, and neither can we from a label.

How to read a recycled polyester claim

Four checks, all possible from the product page or tag.

• Is there a percentage? "Recycled polyester" with no figure should be read as a claim that the whole product is recycled, apart from minor parts. If it is not, the rule asks for the percentage.
• Is the claim about the fabric or the whole product? Linings, trims, zippers and labels can be different materials. The fiber content label still has to show the real mix. Our guide to reading a clothing fiber content label covers what must be disclosed.
• Pre-consumer or post-consumer? The rule treats both as recycled, but pre-consumer claims need evidence that the material would otherwise have been discarded.
• Is there a certificate or a standard? A seal can add evidence, but the rule's tests are about the material itself.

Our explainer on what polyester fabric is covers the fiber itself.

Our take

Treat recycled polyester as a real but modest category. The rule is clear that a bare label overstates unless the whole product is recycled, and the market data shows the material is still about one pound in eight of polyester made, nearly all from bottles. Buy it when the percentage is stated and the garment is built to last. Skip it when the label leans on the word alone. We would watch the textile to textile share, because that 2% is where the claim could someday mean what shoppers imagine.
