US marketing claims compliance starts with one rule: every claim that passed review at home gets checked again against US standards before it runs. Approval from an EU or national self-regulatory body does not transfer, because the US enforcer is the FTC, and the FTC cannot clear your ads in advance.
That makes the audit your job, and US marketing claims compliance a process you run before launch. This is the sixth item on the Compliance & Labeling list in our EU to US Expansion Checklist: audit all marketing claims against US standards, and not only your home market's self-regulatory body. This post explains why and lays out a process.
Do marketing claims that are compliant in the EU need to be re-checked for the US?
Yes. Each claim needs to be re-checked against the evidence and wording standards the FTC applies to US advertising. A claim can be lawful and well supported at home and still fall short in the US, because each system sets its own evidence and wording standards.
Our EU to US Expansion Guide lists the audit as a checklist item for that reason. The FTC's own small-business guidance says plainly that "FTC staff cannot clear your ads in advance." Nobody in the US gives you a stamp of approval before launch, so the burden of proof sits with you from the first ad.
Why doesn't self-regulatory approval at home transfer?
Home approval answers a different question from the one US marketing claims compliance asks. European self-regulatory bodies offer services such as copy advice, in which they check an ad against their rules and national law. According to the European Advertising Standards Alliance (opens in new tab), that advice is voluntary, country-specific, and "cannot completely eliminate the risk" of complaints. It also states that "final and primary responsibility" for ad content stays with the advertiser, and that advice can vary from country to country.
If the advice differs between EU countries, it will not carry over to a country with a separate legal system. Our guide's checklist makes the same point, which is to audit claims against US standards and not only against your home market's self-regulatory body.
The US has its own self-regulatory body, the National Advertising Division, and it works differently. According to the NAD (opens in new tab), any company, consumer, or non-governmental organization can file a challenge, so competitors are a real source of scrutiny. Participation is voluntary, and when an advertiser does not take part or comply, NAD refers the matter to the FTC. The FTC then decides whether to take enforcement action.
Even third-party certifications do not close the gap. The FTC's Green Guides summary (opens in new tab) says that "A marketer with a third-party certification still must substantiate all express and implied claims." By the same logic, home-market approval is no substitute for your own evidence.
What standards does the FTC apply to US marketing claims compliance?
Four ideas do most of the work. Each one is a reason an EU-approved claim can fail the US test.
First, claims need evidence before they run. The FTC's advertising guidance (opens in new tab) says advertisers must have proof for express and implied claims. Under the FTC's notice on substantiation (opens in new tab), an objective product claim needs a reasonable basis at the time it is made, consisting of competent and reliable evidence.
Second, health claims carry a high bar. The FTC's health products guidance (opens in new tab) says health benefit claims generally need randomized, controlled human clinical testing, and it treats "clinically proven" as a claim of proven benefit. Studies on a single ingredient may not support a claim about a combination product. Claims of effectiveness against serious diseases need even stronger evidence.
Third, net impression decides. The same guidance says liability turns on what consumers take away from the whole ad, including text, images, and product names. Implied claims count, and a disclosure that a significant minority of consumers still miss is not enough.
Fourth, specific claim types have their own guides. The Green Guides warn that broad terms such as "green" or "eco-friendly" are hard to substantiate, and they set conditions for recyclable, compostable, recycled content, and carbon offset claims. Endorsements must reflect honest experience and disclose paid or employment connections, and the FTC's fake reviews rule (opens in new tab) bans buying or selling fake reviews.
What does it cost to get a claim wrong?
Weak US marketing claims compliance has real costs. The FTC can issue cease and desist orders, and its small-business page says these can carry daily fines for future violations. It also says civil penalties can run from thousands to millions of dollars, and that remedies can include consumer refunds and corrective advertising. Advertising agencies can be held responsible for misleading ads too.
A challenge may also come from a competitor through NAD, and the process can reach the FTC through a referral. The cheaper moment to find a weak claim is before it is on your product page. Our post on FDA and FTC requirements for EU brands shows how claims also decide how the FDA classifies a product.
How do you audit your claims for US marketing claims compliance?
Work through six steps, and keep the record. Done well, it becomes your evidence file.
Step 1: Build a claims inventory
List every claim across your site, product pages, packaging, ads, emails, social posts, and influencer content. Include implied claims from images, product names, and testimonials, since the FTC reads the whole ad. Our post on US product page localization covers where claims hide on a page.
Step 2: Sort each claim by type
Mark each as an objective product claim, a health or safety claim, an environmental claim, an endorsement or review, a comparative claim, or a price or "free" offer. The type decides which standard applies. Subjective opinions that consumers can judge for themselves draw less FTC attention than claims that can be proven.
Step 3: Match each claim to its evidence
Write down the evidence behind each claim and check that it was in hand before the claim ran. For health claims, ask whether the evidence is human clinical testing on your actual product, formulation, and dose. Evidence on an ingredient, a different formula, or from testimonials alone is unlikely to be enough.
Step 4: Rewrite, qualify, or retire weak claims
Fix claims where the evidence is thin. Qualifiers must be clear and conspicuous, and vague words like "may" or "helps" generally do not convey limited science. A disclosure cannot contradict the claim it qualifies. If you cannot back a claim, retire it.
Step 5: Check testimonials, reviews, and comparisons
Confirm that testimonials reflect typical results or disclose what to expect, and that paid connections are disclosed. Confirm that you do not buy, fake, or suppress reviews. Comparative advertising is legal as long as it is truthful, so check that each comparison is true and current.
Step 6: Get sign-off and set a review cycle
Have counsel or a regulatory specialist review the high-risk claims, particularly health, environmental, and comparative ones. Then set a schedule to re-audit when you add a product, change a formula, or launch a new channel. Our post on getting US counsel and an accountant before launch covers who to hire.
Frequently asked questions
Do marketing claims that are compliant in the EU need to be re-checked for the US?
Yes. EU or national self-regulatory approval does not carry over, because the FTC applies its own evidence standards and does not clear ads in advance. Re-check every claim before it runs, starting with health and environmental claims. That is the core of US marketing claims compliance.
Does my home-market ad approval protect me in the US?
No. For US marketing claims compliance, copy advice from a European self-regulatory body is voluntary and country-specific, and the advertiser keeps final responsibility. The FTC says it cannot clear ads in advance, so treat the advice as a useful starting point only.
How much evidence do I need for a health claim?
The FTC's guidance says health benefit claims generally need randomized, controlled human clinical testing relevant to your product. Studies on single ingredients, animals, or lab models, and testimonials, are not enough on their own. Serious disease claims need even more.
Who can challenge my claims in the US?
The FTC can act, and through NAD any company, consumer, or non-governmental organization can file a challenge, so a competitor can raise your claims. If an advertiser does not comply with NAD, the case goes to the FTC.
