## Key Takeaways

- US microplastics claims fall under FTC Green Guides Section 260.9, which requires solid scientific evidence, clear claim scope, and documented detection limits for any “free-of” wording.
- Absolute claims like “microplastic-free” are effectively indefensible because current validated methods cannot confirm complete absence across all particle sizes and polymer types.
- Four common claim types carry different evidence requirements: “microplastic-free” needs non-detect results, “no intentionally added” needs composition documentation, and the two release claims, “does not release” and “reduces release,” need migration testing under actual use conditions.
- Every “none detected” result is bounded by the method’s detection floor, and California SWB-MP1 and SWB-MP2 methods start at 50 µm and 20 µm respectively, which leaves smaller particles unvalidated.
- The Wellness Quality Institute provides independent review of existing third-party laboratory data against published criteria (WQI-CS-01) aligned with the California State Water Board framework, issues scope-locked approved claim language, and lists verified products on a public registry.

## Core Requirements For Any Microplastics Claim

Five conditions set the minimum bar for any microplastics-related claim a US brand publishes.

1. A defined claim wording and scope, specifying the product, the material being tested (for example, the liquid inside the bottle), and the production period the claim covers.
2. Competent and reliable scientific evidence, as required under the [FTC Green Guides](https://ecfr.gov/current/title-16/chapter-I/subchapter-B/part-260), meaning tests, analyses, or studies that qualified experts conduct and evaluate using methods their field generally accepts.
3. A qualified independent laboratory using a validated analytical method, with disclosed detection limits, which is the lowest concentration the instrument can reliably find, and quantification limits, which is the lowest concentration it can measure accurately.
4. Documented quality controls, including procedural blanks, which are samples run without the product to catch contamination from the lab itself, spike recoveries, which confirm the method can find what it should, replicates, and a chain of custody that shows the sample stayed intact between collection and analysis.
5. Independent review and claim language that stays inside what the evidence actually supports.

This list sets the floor. Some claim types and product matrices need more documentation. Defining the claim wording often causes the first breakdown, because the words chosen determine every later evidence requirement.

## FTC Green Guides Baseline For Microplastics Claims

US brands work within FTC substantiation under Section 5 of the FTC Act and [16 CFR Part 260](https://ecfr.gov/current/title-16/chapter-I/subchapter-B/part-260), the Green Guides. There is no standalone federal microplastics certification program and [no general microplastics-specific disclosure mandate for consumer products in the United States](https://hklaw.com/en/insights/publications/2026/07/epa-proposes-ucmr-6-for-pfas-and-other-contaminants). The Green Guides [do not create legal rights](https://ecfr.gov/current/title-16/part-260), but the FTC [can bring an enforcement action against a marketer](https://ecfr.gov/current/title-16/part-260) whose claim conflicts with them, and [the Commission must prove the practice is unfair or deceptive under Section 5](https://ecfr.gov/current/title-16/part-260).

[Section 260.9(c)](https://ecfr.gov/current/title-16/section-260.9) sets out [three conditions under which a “free-of” claim may be appropriate](https://ecfr.gov/current/title-16/chapter-I/subchapter-B/part-260/section-260.9) even when a trace amount of the substance is present. All three must be satisfied at the same time.

1. The level present is no more than an acknowledged trace contaminant or background level.
2. The substance’s presence does not cause material harm that consumers typically associate with that substance.
3. The substance was not intentionally added to the product.

[Footnote 47 to Section 260.9](https://ecfr.gov/current/title-16/chapter-I/subchapter-B/part-260/section-260.9) notes that “trace contaminant” and “background level” are imprecise terms and that what qualifies requires a case-by-case analysis.

“Microplastic-free” is the hardest claim to defend under these conditions. Microplastics are widespread in the environment and [appear in tap water, bottled water, and ambient air](https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0194970), which makes a recognized “background level” for a specific product very hard to establish. Microplastics also have a strong association with beverage and food-contact products, which weakens the second condition. [Section 260.2](https://ecfr.gov/current/title-16/chapter-I/subchapter-B/part-260) requires that [every reasonable interpretation of a claim be truthful and supported](https://ecfr.gov/current/title-16/part-260) before publication, and [Section 260.1(d)](https://ecfr.gov/current/title-16/section-260.9) makes clear that [the net impression of the label](https://ecfr.gov/current/title-16/part-260) determines whether a claim is deceptive.

![Fragments of plastic suspended in blue water below the surface.](https://cdn.aigrowthmarketer.co/1784829388732-c6255482b477.webp)**Plastic doesn't disappear — it fragments. These secondary microplastics are the breakdown products of everyday objects, and independent research now detects them across the water supply. Detection, though, establishes presence, not absence.**

## The Claim-Type Matrix

The four most common microplastics claim types carry different evidence requirements. The table below maps each claim wording to what it asserts, what evidence it requires, and the overclaim it most often invites.

| Claim Wording | What It Asserts | Evidence It Requires | Overclaim It Invites |
| --- | --- | --- | --- |
| Microplastic-Free | Complete absence of microplastics in the product | Non-detect results across all particle sizes and polymer types, a standard no current method can meet | Implies total absence, is bounded by the detection floor, and is effectively indefensible as an absolute claim |
| No Intentionally Added Microplastics | Microplastics were not deliberately included as an ingredient or functional component | Composition documentation and supplier declarations confirming no microplastics were added by design | May be read by consumers as equivalent to “microplastic-free” without a clear qualifier |
| Does Not Release Microplastics | The product or packaging does not shed microplastic particles during normal use | Migration or release testing under the actual use scenario, such as temperature, pH, and mechanical stress, because composition data alone is insufficient and results are scenario- and method-dependent | Implies zero release across all conditions and particle sizes and requires scenario-specific testing |
| Reduces Microplastic Release | The product or packaging releases fewer microplastics than a comparator | Comparative release testing of treated versus untreated products under the same use conditions against a defined baseline, with careful control of variables and enough replicates to show statistical significance, and a clearly identified comparator | Vague comparisons and unclear baselines that may overstate the reduction if the comparator is not disclosed |

The table above shows the four claim types side by side. “Microplastic-free” asserts absence, which no laboratory can currently substantiate across all particle sizes and polymer types. “No intentionally added microplastics” asserts sourcing intent, which composition records and supplier documentation can support. The two release claims need a different kind of evidence entirely, which is migration testing under the actual use conditions, because a composition test cannot show what a product sheds. Those results are scenario- and method-dependent, as [studies of polypropylene, PET, and PS containers](https://www.retrocycle.org/assets/pdfs/microplastic-emission-takeaway-containers-2025.pdf) show. The wording choice is the single biggest lever a brand controls before publishing any microplastics claim.

## The Measurement-Limit Problem: Why “None Detected” Is Bounded

That distinction between asserting absence and asserting intent only matters because of how microplastics are measured. Every microplastics test result is bounded by the detection floor of the method used. California’s two published analytical methods, SWB-MP1-rev1, which uses infrared spectroscopy and is validated for particles greater than 50 µm through 5,000 µm, and SWB-MP2-rev1, which uses Raman spectroscopy and is validated for particles greater than 20 µm through 5,000 µm, represent the most defensible public reference framework. The 1–20 µm fraction is not validated under either method. California’s regulatory definition of microplastics reaches down to 1 nanometer across at least three dimensions, which is thousands of times smaller than where the best validated methods begin.

![Colorful plastic fragments in water inside a laboratory petri dish.](https://cdn.aigrowthmarketer.co/1784829410323-fb401fc7b1e4.webp)**Microplastics are particles smaller than five millimeters. Current methods can count and identify them at the upper end of that range, but reliable measurement falls away as particles get smaller — a limit that shapes every honest claim.**

A result of “none detected” means none were found above that instrument’s detection floor, for the polymers it screened, in the lot it tested. It does not mean none are present. No laboratory can confirm complete absence of plastic across every particle size, polymer type, and production lot. An absolute “microplastic-free” claim cannot rest on this basis. For a more detailed treatment of method ranges and detection limits, see [Microplastics Standards: Methods & Claim Limits Explained](https://www.wellnessqualityinstitute.com/articles/microplastics-standards-guide/?utm_term=minimum-requirements-microplastics-claims&utm_campaign=ai_growth_agent).

## Building A Substantiation File Your Legal Team Can Use

A substantiation file is the document set that answers what a claim actually supports. The following elements form the minimum file a brand should be able to produce before publishing any microplastics-related claim.

- Product composition and polymer identification for all materials in contact with the product
- Analytical method used and its validated detection range
- Limits of detection and quantification for the specific method and matrix
- Blank and contamination-control results, including procedural blanks run alongside samples
- Spike recoveries and replicate results that confirm method performance
- Sampling plan and the production period the samples represent
- Chain of custody documentation from sample collection through analysis
- Laboratory accreditation records, such as California ELAP accreditation for the applicable SWB method or ISO/IEC 17025 accreditation with the specific method and matrix explicitly within scope
- A written substantiation report stating what the data supports and where its limits sit, prepared by a qualified independent party

For guidance specific to packaging and label claims, see [Microplastics Packaging Claims: A US Brand Compliance Guide](https://www.wellnessqualityinstitute.com/articles/retail-packaging-microplastics-claim-requirements/?utm_term=minimum-requirements-microplastics-claims&utm_campaign=ai_growth_agent).

## US And EU Microplastics Claim Requirements Compared

In the United States, the operative framework for microplastics claims is FTC Green Guides substantiation under Section 5 of the FTC Act. There is no general federal microplastics disclosure mandate for consumer products. The [Microbead-Free Waters Act of 2015](https://www.congress.gov/bill/114th-congress/house-bill/1321) [bans plastic microbeads in rinse-off cosmetics](https://americanbar.org/groups/environment_energy_resources/resources/year-in-review/2025/enforcement-litigation). It is a narrow, product-category-specific prohibition and does not create a general claim standard or a basis for a “microplastic-free” label on other product types.

In the European Union, Commission Regulation (EU) 2023/2055, which applied from October 17, 2023, restricts the placing on the market of intentionally added synthetic polymer microparticles under REACH Annex XVII, Entry 78. The regulation targets a defined regulatory category of intentionally present synthetic polymer microparticles. It applies with product-specific derogations and [phase-in periods ranging from four to twelve years depending on the product category](https://eur-lex.europa.eu/eli/reg/2026/1168/oj/eng). Compliance with EU 2023/2055 does not prove a product contains no microplastics and does not authorize a blanket “microplastic-free” marketing claim. A US brand cannot import EU regulatory compliance as US substantiation because the two frameworks address different questions under different legal regimes.

## Recent US Policy Signals On Microplastics

If the EU framework is relatively settled and the US framework is still thin, the United States is at least moving. On April 2, 2026, the EPA [proposed adding microplastics as a priority contaminant group to the draft sixth Drinking Water Contaminant Candidate List, or CCL 6](https://velaw.com/insights/microplastics-move-into-the-federal-policy-pipeline-what-plastics-and-chemicals-companies-need-to-know-now), under the Safe Drinking Water Act, which is [the first time microplastics have appeared on that list](https://hklaw.com/en/insights/publications/2026/07/epa-proposes-ucmr-6-for-pfas-and-other-contaminants). The draft CCL 6 designation does not impose any compliance obligation on brands today and does not create a consumer-facing product disclosure or labeling requirement. Separately, HHS launched the [Systematic Targeting of MicroPlastics, or STOMP, program, a $144 million research initiative](https://velaw.com/insights/microplastics-move-into-the-federal-policy-pipeline-what-plastics-and-chemicals-companies-need-to-know-now) focused on measuring and studying microplastics in the human body, which is a research signal rather than a labeling mandate.

Microplastics were [omitted from EPA’s proposed UCMR 6](https://hklaw.com/en/insights/publications/2026/07/epa-proposes-ucmr-6-for-pfas-and-other-contaminants) because no validated federal test method with adequate quality control was available in time. These federal actions show a clear direction of travel, since microplastics have moved from the margins of the federal policy agenda toward its center, but they create no consumer-labeling or disclosure obligation today.

## Why Independent Review Matters And How The Wellness Quality Institute Helps

A lab report and a defensible market claim are not the same thing. A brand can hold a report reading “no microplastics detected” and not realize the finding is bounded by that instrument’s detection floor, which means none found above 50 µm using this method on this lot, not none present. That gap is exactly why self-reported results get discounted as marketing, because the company grading its own homework has an obvious interest in the grade.

![Scientists in white coats working with samples and microscopes in a laboratory.](https://cdn.aigrowthmarketer.co/1784829434095-0fc8fbcf29fa.webp)**Only a small number of laboratories can genuinely test for microplastics, and capability varies by instrument and method. WQI reviews a company's existing third-party laboratory data against a defined standard — it does not run the tests itself.**

The Wellness Quality Institute is the leading independent reviewer of microplastics claim substantiation for US brands. WQI’s core program, Plastic-Free Pathway Verification, or PFPV, governed by the standard WQI-CS-01, reviews a company’s existing third-party laboratory dataset against defined criteria aligned with the California State Water Board’s drinking-water microplastics reference framework. That alignment serves as a technical reference point rather than a California approval or endorsement. WQI does not perform laboratory testing. It reviews the data, method, and controls that a qualified independent laboratory has already produced.

![A single water droplet creating concentric ripples on a blue surface.](https://cdn.aigrowthmarketer.co/1784829453151-0debb98043a6.webp)**A credible conversation about plastics in water depends on measurement and standards that don't yet exist for the category. WQI's role is to bridge the gap between real laboratory data and a claim a company can actually stand behind.**

Every review produces one of two outcomes. Standard Met carries a verification decision, a scope-locked license to use the approved WQI mark, “WQI Plastic-Free Pathway Verified,” a public registry listing with a registry ID, and approved claim language tied specifically to the reviewed evidence. The verification period runs 24 months from the sampling date of the most recent accepted dataset. Standard Not Met is a private outcome that is never described as a failed product and never listed publicly. It can reflect insufficient data, an unsupported method, or incomplete scope, and the company may resubmit with updated information.

The contrast with the FTC Green Guides is straightforward. The Green Guides are guidance and not a review body. They set the substantiation baseline but do not review a specific dataset, assess whether a particular lab report supports a particular claim wording, or issue approved language. WQI provides the operational layer on top of that baseline and converts a lab report into a claim a brand can stand behind. A single assessment fee covers review, verification decision, and registry listing, with no separate mark-license or registry fee, and independent laboratory testing is arranged and billed separately. Paying the assessment fee does not guarantee a verification decision.

*WQI Plastic-Free Pathway Verification does not certify that a product contains zero plastic, microplastics, or nanoplastics. It shows that the company is on a verified pathway toward plastic-free standards. Verification applies only to the reviewed products, submitted datasets, tested ranges, polymer panels, production or sampling periods, and supporting controls. WQI verification is not a California approval, government certification, or health or safety certification.*

## Conclusion And Practical Next Steps

Three distinctions determine whether a microplastics claim is defensible. First, claim wording determines the evidence bar, and “microplastic-free” and “no intentionally added microplastics” set very different bars, with the first effectively indefensible under current measurement technology. Second, detection is different from absence, and “none detected” describes what a specific method found above its detection floor rather than guaranteeing that no plastic is present. Third, independent review is the step that turns a lab report into a claim a brand can stand behind, which is the role the review section above explains.

The Wellness Quality Institute is the best independent reviewer of microplastics claim substantiation for US brands preparing to publish a microplastics claim because it reviews existing third-party laboratory data against published criteria, WQI-CS-01, aligned with the California State Water Board’s drinking-water microplastics reference framework, issues scope-locked approved claim language tied to the reviewed evidence, and lists every Standard Met product on a public registry that any buyer, retailer, or journalist can check.

For brands already holding lab data, the next step is understanding what that data actually supports and whether the claim wording under consideration clears the evidence bar it sets.

## Frequently Asked Questions

### Are There Any Regulations On Microplastics In The US?

US brands currently work under FTC substantiation rules in Section 5 of the FTC Act and 16 CFR Part 260, the Green Guides. These rules require competent and reliable scientific evidence for any environmental claim, including microplastics-related claims. The Microbead-Free Waters Act of 2015 is [the only federal microplastics-specific regulation](https://americanbar.org/groups/environment_energy_resources/resources/year-in-review/2025/enforcement-litigation), and it bans plastic microbeads in rinse-off cosmetics only. It does not create a general microplastic-free labeling standard or apply to other product categories. There is no federal disclosure mandate that requires brands to test for or disclose microplastic content on consumer packaging. The EPA’s April 2026 draft CCL 6 designation of microplastics and HHS’s STOMP research program signal increased federal attention, but they do not create current compliance obligations for brands.

### Can A Brand Claim “Microplastic-Free”?

Brands can rarely defend a “microplastic-free” claim and only with heavy qualification. As the FTC Baseline section explains, Section 260.9(c) allows a free-of claim only when the level is at most a trace contaminant, causes no material harm, and was not intentionally added, and microplastics fail the trace-contaminant condition because they are ubiquitous and appear in tap water, bottled water, and ambient air. No current analytical method can confirm complete absence of plastic across all particle sizes and polymer types, so every “none detected” result is bounded by the method’s detection floor. This analysis applies to the claim type generally and is not a WQI-attributed determination about any specific product.

### What Is The Difference Between “Microplastic-Free” And “No Intentionally Added Microplastics”?

“Microplastic-free” asserts complete absence and would require ruling out every particle below the detection floor, every polymer outside the tested panel, and every production lot not sampled. No method can do this today, so the claim is effectively indefensible as an absolute statement. “No intentionally added microplastics” asserts sourcing intent, which means microplastics were not deliberately included as an ingredient or functional component of the product. This claim is defensible with composition documentation and supplier declarations that confirm no microplastics were added by design. The evidence bars differ, since one attempts to prove a negative across an open measurement space and the other documents a manufacturing decision. Some consumers may still read “no intentionally added microplastics” as equivalent to “microplastic-free,” which is why a clear qualifying statement helps.

### What Detection Limits Must A Microplastics Claim Disclose?

A defensible substantiation file should disclose the analytical method used, its validated detection range, and both the limit of detection, which is the lowest concentration the instrument can reliably detect, and the limit of quantification, which is the lowest concentration it can measure accurately. As covered in the measurement-limit section, the two California methods validate down to 50 µm and 20 µm respectively, which leaves the 1–20 µm fraction unvalidated and far above the 1 nanometer floor in California’s definition. Any claim must match what the method can actually detect, and implying that a result covers particle sizes outside the method’s validated range overstates what the data shows.

### What Documents Should Be In A Substantiation File?

A minimum substantiation file for a microplastics claim should include product composition and polymer identification, the analytical method and its validated range, limits of detection and quantification, blank and contamination-control results, spike recoveries and replicates, a sampling plan and the production period the samples represent, chain of custody documentation, laboratory accreditation records confirming the lab is qualified for the specific method and matrix, and a written substantiation report stating what the data supports and where its limits sit. Legal teams use this file to evaluate whether a proposed claim wording is defensible, and independent reviewers or plaintiff’s attorneys will examine it if the claim faces a challenge.

### Does EU 2023/2055 Ban Microplastics?

Commission Regulation (EU) 2023/2055 restricts the placing on the market of intentionally added synthetic polymer microparticles under REACH Annex XVII, Entry 78. It does not operate as a general prohibition on all microplastics in all products. The regulation targets synthetic polymer microparticles that are intentionally present in a product to provide a desired characteristic. It also applies with product-specific derogations and [phase-in periods ranging from four to twelve years depending on the product category](https://eur-lex.europa.eu/eli/reg/2026/1168/oj/eng). Compliance with EU 2023/2055 does not prove a product contains no microplastics and does not authorize a “microplastic-free” label. The regulation focuses on market placement and related information or reporting controls rather than a universal analytical certification of absence.

### Is WQI Verification A Certification?

WQI’s Plastic-Free Pathway Verification is a verification of reviewed data and demonstrated progress and not a certification that a product is free of plastic. The Wellness Quality Institute deliberately avoids “certified” and “certification” for this program. A certification implies a settled, guaranteed state, and current measurement limits do not support that kind of guarantee. Verification describes what actually happened, which is an independent review of a company’s existing third-party laboratory dataset against a defined standard, WQI-CS-01. WQI verification is not a California approval, government certification, or health or safety certification.

### Does WQI Perform The Testing?

The Wellness Quality Institute reviews existing third-party laboratory data and does not run laboratory tests. Independent laboratory testing is arranged and billed separately by a qualified independent laboratory. That laboratory is California ELAP-accredited for the applicable SWB method, which is a preferred credential, ISO/IEC 17025-accredited with the specific method and matrix explicitly within scope, which is an accepted option, or conditionally accepted through a documented method-equivalence review. WQI’s independence from the testing it reviews is central to the program’s credibility because it has no commercial interest in the outcome and no role in producing the data it assesses.

WQI verification is not a California approval, government certification, or health or safety certification.
    **Question:**

    - **Name:** Does WQI Perform The Testing?
      **Answer:**

      - **Text:** The Wellness Quality Institute reviews existing third-party laboratory data and does not run laboratory tests. Independent laboratory testing is arranged and billed separately by a qualified independent laboratory. That laboratory is California ELAP-accredited for the applicable SWB method, which is a preferred credential, ISO/IEC 17025-accredited with the specific method and matrix explicitly within scope, which is an accepted option, or conditionally accepted through a documented method-equivalence review. WQI’s independence from the testing it reviews is central to the program’s credibility because it has no commercial interest in the outcome and no role in producing the data it assesses.
