Do FTC Disclosure Rules Apply to a Danish Influencer Working With a US Brand?

Short answer: yes, potentially — and it's not either/or with Danish law

The US Federal Trade Commission (FTC) enforces its own disclosure rules — the Endorsement Guides (16 C.F.R. Part 255) — against anyone whose content reaches US consumers, regardless of where that person is physically located. Multiple independent compliance sources, each citing the FTC's own "Disclosures 101 for Social Media Influencers" guidance as their source, describe the same standard consistently: US law applies if it's "reasonably foreseeable" that a post will affect US-based consumers — whether the influencer posting it is sitting in Copenhagen, Paris or Tokyo.

The important thing to understand first: this isn't a question of which rulebook applies instead of the other. A Danish influencer working with a US brand is already covered by Danish and EU disclosure law, regardless of which country the brand is based in. The question this article actually answers is whether a second rulebook stacks on top — not whether the Danish one goes away.

The legal basis: the FTC's own "reasonably foreseeable" standard

The FTC's own pages (ftc.gov) could not be fetched directly during research for this article (access was blocked); the standard below is corroborated across several independent compliance sources that each cite the FTC's own guidance as their source — it is not an independent interpretation by Make Influence.

• The FTC's Endorsement Guides apply to advertising and endorsements directed at, or reasonably likely to reach, US consumers — regardless of where the person posting is physically located.
• The statute behind the FTC's enforcement authority, FTC Act Section 5, 15 U.S.C. § 45(a)(4), contains an explicit foreign-commerce provision, added by the US SAFE WEB Act in 2006: an "unfair or deceptive practice" involving foreign commerce is covered if it (i) causes or is likely to cause reasonably foreseeable injury within the United States, or (ii) involves material conduct occurring within the United States.
• That provision carries a sunset date: 30 September 2027. The FTC has repeatedly asked Congress to make it permanent instead of letting it lapse — it remains in force as of this writing (24 August 2026), and its status is worth re-checking again closer to 2027.

What actually triggers it

Two things generally both need to be present before the FTC's rules genuinely come into play for a Danish influencer:

A US brand paying a Danish influencer for a post that goes out on a public, English-language, or otherwise US-oriented account typically hits both criteria. A post entirely in Danish, aimed at a Danish audience, where the brand simply happens to be headquartered in the US, is a much weaker case for the FTC.

The legal question isn't the same as the practical risk question

That the FTC's rules can apply as a matter of law isn't the same as enforcement against a single Danish influencer with no US presence being likely in practice. It's worth keeping the two questions separate:

• The legal question: can the FTC's rules apply to this situation? Yes, if the criteria above are met.
• The practical question: how likely is it that the FTC actually pursues one foreign-based individual creator? The FTC's own enforcement record in influencer cases points consistently the other way: in its best-known influencer case, the 2016 settlement with Lord & Taylor — where 50 influencers received payment and a free dress in exchange for undisclosed posts — it was Lord & Taylor itself, the advertiser, that was bound by the resulting order, not the 50 individual influencers.

This research pass found no publicly known case of the FTC bringing a standalone action against a purely foreign-based individual creator with no US presence. That doesn't mean it's impossible — but it's consistent with a practical logic: a US brand typically has US assets and a US legal entity, and is far easier for the FTC to pursue and enforce a judgment against than an individual in another country with no assets in the US.

Decision framework: should a Danish influencer or brand actually account for the FTC?

IF you're working with a US brand, AND the post is publicly visible to an audience that could reasonably include US consumers → write the disclosure so it also satisfies the FTC's standard (see the comparison table below), not just the Danish one.

IF the post is aimed purely at a Danish audience (language, geographic targeting, platform settings) → Danish/EU disclosure law is the rule that actually governs; FTC risk is meaningfully lower, though not necessarily zero if the brand itself is US-based and the content is still public.

IF you're unsure, and the collaboration is large or recurring → write a disclosure that satisfies both rulebooks at once. It costs nothing extra to get right from the start, and it removes the question entirely.

Danish/EU disclosure vs. the FTC's standard, side by side

Make Influence's recommendation

In our experience, it's rarely necessary to choose between the two rulebooks — in practice they pull in the same direction: disclose clearly, at the start of the post, without burying it in a hashtag pile-up at the bottom. For a US-brand collaboration, write into the brief that the disclosure needs to satisfy Danish/EU practice (see the sibling article on Danish/EU disclosure) and use a clear, unambiguous term like "#ad" as well — that covers both rulebooks with the same disclosure, at no extra cost. Either way, write the exact disclosure wording into the brief itself — see what to put in an influencer contract for where that belongs alongside deliverables and usage rights. It's an insurance policy, not a duty you're likely to be tested on — but it's a cheap one to take out.

FAQ

Do I need to write both "reklame for [brand]" and "#ad" if the brand is American?

Writing both isn't a legal requirement, but it's the practical approach most likely to satisfy both rulebooks at once. "Reklame for [brand]" alone satisfies the Danish requirement; adding a clear English-language marker like "#ad" makes the same post more robust against the FTC's standard if the audience extends beyond Denmark.

Has the FTC ever brought a case against an influencer based outside the US?

This research pass found no publicly known case of the FTC independently pursuing a purely foreign-based individual creator. The FTC's best-known influencer case (Lord & Taylor, 2016) ended in a settlement with the US brand, not with the influencers involved.

Is "#partner" or "#collab" enough to satisfy the FTC's rules?

Per the compliance sources this article relies on (which themselves cite the FTC's own guidance), vague terms like "#partner," "#collab" and "#ambassador" alone are not considered sufficient, because they assume a consumer who already understands industry jargon. "#ad" and similarly unambiguous wording are considered sufficient.

If the US brand's contract requires FTC-compliant disclosure, does that override Danish law?

No. A contract clause can add a requirement on top, but it can never remove the Danish disclosure duty, which applies independently of what the contract says. Both rulebooks apply in parallel, not one instead of the other — see what to put in an influencer contract for how to write the disclosure requirement into the agreement itself.

Does a Danish company selling into the US market fall under the FTC the same way an individual influencer does?

The underlying principle is the same — reasonably foreseeable injury to US consumers — but a company with a genuine, ongoing US business is a more obvious target for the FTC to pursue than an individual influencer with a one-off collaboration, for exactly the practical reason covered above: assets and presence that can actually be enforced against.

Is this the same question as US withholding tax (W-8BEN) on the payment from the US brand?

No — these are two entirely separate questions that can both come up in the same collaboration. This article covers disclosure law (whether the post has to be marked as an ad). Whether the payment itself from the US brand triggers US withholding tax depends on where the work is performed, not on ad disclosure. See how to pay international influencers: currency, invoicing and tax basics for the withholding-tax question.

Does the UK have a similar "reasonably foreseeable" cross-border test?

No — the UK's system works differently. The ASA's CAP Code applies based on whether the brand paid for or exercised editorial control over the content, not on where the audience happens to be, and its statutory backstop, the CMA, can fine directly for up to 10% of global turnover since 6 April 2025 — a different mechanism from the FTC's foreign-commerce standard covered here. See the UK's ASA/CAP Code vs Denmark's influencer disclosure rules, compared for the full breakdown.

Is the FTC's own agency enforcement the only US legal risk a brand faces over undisclosed influencer content?

No. Since 2025, US consumers have separately sued brands like Gymshark, Alo Yoga and Revolve directly under state consumer-protection law over undisclosed sponsorships — private class-action litigation that doesn't rely on the FTC bringing a case at all, and that targets the brand rather than a foreign creator. See the 2026 US influencer-disclosure class actions: what they mean for brand liability for how that separate mechanism works and what's happened in each case so far.
