Running a KOL campaign on Xiaohongshu or Douyin without understanding China's advertising compliance rules is not just a reputational risk — it is a legal one. China has built one of the most detailed regulatory frameworks for influencer and sponsored content in the world, and enforcement is real: brands and KOLs alike have faced public investigations, platform bans, and financial penalties for violations that might barely register as concerns in Western markets.
For international brands entering China, navigating this landscape is non-negotiable. Whether you are seeding products with micro-influencers on Xiaohongshu (RedNote), running a live-stream campaign on Douyin, or partnering with a celebrity KOL on Weibo, the same core obligations apply: sponsored content must be disclosed, claims must be substantiated, and certain categories of content are strictly off-limits.
This guide breaks down everything international brand marketers need to know about KOL marketing legal requirements in China — from the foundational advertising laws and platform-specific rules, to disclosure formats, prohibited claims, and what happens when brands get it wrong. If you are planning or scaling KOL activity in China, read this before you brief a single influencer.
Why Compliance Matters in China's KOL Marketing Landscape {#why-compliance-matters}
China's influencer marketing industry is enormous. The market was projected to surpass 3.9 trillion yuan in value, and platforms like Xiaohongshu now serve over 300 million monthly active users who rely heavily on KOL recommendations for purchasing decisions. This scale has not gone unnoticed by regulators.
Since 2021, Chinese authorities — including the State Administration for Market Regulation (SAMR) and the Cyberspace Administration of China (CAC) — have significantly intensified oversight of influencer-driven advertising. Campaigns that fail to properly label sponsored content, make unsubstantiated product claims, or use testimonial formats without proper disclosures are now routinely flagged, both by algorithms and by user reports.
For international brands, the stakes are particularly high. A compliance failure on a high-profile campaign can result in platform delisting, negative press that spreads quickly within China's social media ecosystem, financial penalties imposed on the brand's local entity, and damage to the very trust with Chinese consumers that KOL marketing is designed to build. Understanding the rules is not bureaucratic box-ticking — it is a prerequisite for sustainable growth in the market.

The Legal Framework Governing KOL Marketing in China {#legal-framework}
China's approach to regulating influencer advertising is layered. There is no single "influencer law," but rather a set of overlapping statutes, regulations, and platform policies that together define what is permissible. International brands need to be familiar with all three levels.
The Advertising Law of the People's Republic of China {#advertising-law}
First enacted in 1994 and substantially revised in 2015 and again updated in 2021, the Advertising Law is the foundational document for all commercial marketing communications in China. It applies to KOL-generated sponsored content just as it applies to traditional advertisements.
Key obligations under the Advertising Law include:
• Truthfulness: All advertising content must be truthful, accurate, and not misleading. Claims about product efficacy, ingredients, rankings, or awards must be verifiable.
• Identification of advertisements: Any content that constitutes a commercial advertisement must be clearly identifiable as such. Content that disguises advertising as organic editorial is explicitly prohibited.
• Endorser liability: Under Article 38, individuals who endorse products in advertising — which includes KOLs and influencers — bear legal responsibility if those endorsements are false or misleading. This means your KOL partners carry personal legal exposure, not just your brand.
• Category-specific restrictions: The law imposes heightened requirements on advertising for products in sensitive categories including food, pharmaceuticals, medical devices, cosmetics, financial products, alcohol, and products targeting minors.
The Internet Information Service Algorithmic Recommendation Regulations {#algorithmic-regulations}
Effective March 2022, the Algorithmic Recommendation Regulations issued by the CAC introduced obligations specifically relevant to platform-distributed sponsored content. These rules require that platforms using algorithmic recommendation (which includes every major Chinese social and short-video platform) ensure that commercial content delivered through their systems is transparently labeled and does not unfairly manipulate consumer behavior.
For brands, this means that sponsored content distributed through KOL channels on platforms like Xiaohongshu must carry disclosures that are visible to both the platform's own moderation systems and to end users. It is no longer sufficient to rely on vague language or buried disclosures at the end of a long caption.
Platform-Level Rules: Xiaohongshu's Own Standards {#platform-rules}
Beyond national law, each platform maintains its own community standards and commercial content policies. Xiaohongshu (RedNote/Little Red Book) has developed particularly detailed rules for branded content, reflecting its positioning as a trusted discovery and review platform.
Xiaohongshu requires that all posts created in exchange for payment, gifting, or any other form of consideration be submitted through its Brand Partner Platform (品牌合作人平台) or otherwise clearly labeled using the platform's official sponsored content tags. Posts that present paid content as independent reviews — a practice sometimes called "grass-planting fraud" (虚假种草) — are subject to removal and can result in the KOL's account being penalized or banned.
Xiaohongshu has also published prohibited content categories that go beyond national advertising law, including restrictions on exaggerated before-and-after comparisons, false lifestyle portrayals, and content that implies exclusivity or scarcity without factual basis.

Mandatory Disclosure Requirements for Sponsored Content {#disclosure-requirements}
Disclosure is the most operationally important compliance area for brands running KOL campaigns. Getting it right protects both the brand and the KOL.
What Must Be Disclosed {#what-must-be-disclosed}
Any content produced by a KOL that involves a commercial relationship with a brand must be disclosed. This includes:
• Paid partnerships: Direct fees paid to the KOL for creating or publishing content.
• Product gifting: Products provided free of charge in exchange for a review or mention, even if no cash payment is made.
• Affiliate arrangements: Commissions earned through embedded shopping links or live-stream purchase conversions.
• Brand-sponsored trips or events: Attendance at brand events, store openings, or press trips that result in content creation.
The common misconception among brands new to the China market is that product gifting does not require disclosure because no money changed hands. Under both the Advertising Law and Xiaohongshu's own policies, any form of commercial consideration triggers the disclosure obligation.
How Disclosures Must Appear {#how-disclosures-appear}
Disclosures must be prominent, clear, and positioned so that viewers see them before engaging with the substantive content. On Xiaohongshu, the platform's official sponsored content label (合作) appears automatically when content is submitted through the Brand Partner Platform and is considered the gold standard for compliance.
For content published outside of official brand partnership channels (for example, in live-stream formats or story-style posts), the standard practice is to include a clear disclosure in the post title or opening lines — not buried in hashtags at the bottom of the caption. Phrases such as "广告" (advertisement) or "品牌合作" (brand partnership) are the accepted disclosure formats in Chinese-language content.
Brands should never instruct KOLs to omit disclosures or to use ambiguous language that obscures the commercial nature of the content. Beyond legal risk, this approach is increasingly counterproductive: Chinese consumers are sophisticated and often respond more positively to transparent disclosures than to content that feels deceptive.

Prohibited Content and Claims Under Chinese Law {#prohibited-content}
Beyond disclosure, brands must ensure that the substantive content of KOL posts complies with Chinese advertising law. Several categories of claims are prohibited outright or require special approvals.
Superlative language is one of the most common pitfalls for international brands. The Advertising Law prohibits the use of absolute or superlative terms such as "国家级" (national-level), "最" (the most/best), "第一" (number one), or "顶级" (top-tier) in advertising copy unless they can be specifically substantiated. In practice, this means KOL posts describing your product as "China's best moisturizer" or "the No. 1 serum" are non-compliant unless your brand holds a verifiable, officially recognized ranking or certification.
Medical and health claims are subject to particularly strict control. Cosmetics may not claim pharmaceutical or therapeutic effects. Food products may not suggest disease prevention or treatment. Any claim that a product "cures," "treats," or "clinically proven" requires substantiation and, in many cases, pre-approval from the National Medical Products Administration (NMPA). KOL content in the beauty and wellness space frequently runs afoul of these rules when influencers describe product effects using language that crosses into medical territory.
Testimonials and before-and-after content must reflect genuine user experience. A KOL cannot endorse a product they have not personally used, and comparative visual content (such as skin transformation photos) must accurately represent results achievable by typical users.
Content targeting minors is subject to additional restrictions across all categories. Brands in toys, food, and education sectors in particular must review KOL content carefully for compliance with rules limiting persuasive techniques aimed at audiences under 18.

KOL Contracts and Brand Liability: What International Brands Must Know {#kol-contracts}
A common mistake international brands make when working with Chinese KOLs — especially through intermediary agencies — is assuming that compliance responsibility sits entirely with the influencer. This is legally incorrect and operationally dangerous.
Under Chinese advertising law, brands (as advertisers) are jointly liable for violations in sponsored content they commission or approve. If a KOL publishes a misleading product claim on your behalf — even if the specific wording was the KOL's own — your brand can face regulatory action if it is demonstrated that you knew or should have known about the non-compliant content.
This makes contract-level compliance clauses essential. Agreements with KOLs or their management agencies should explicitly:
• Require disclosure in all sponsored posts as specified by applicable law and platform policies.
• Prohibit the use of superlative, medical, or otherwise non-compliant claims.
• Require the KOL to submit content for brand compliance review before publishing.
• Include indemnification provisions that address regulatory penalties arising from KOL-side violations.
• Specify that content must be submitted through official brand partnership channels (such as Xiaohongshu's Brand Partner Platform) where applicable.
For international brands operating through a local distributor or agency, it is worth requesting confirmation that these standards are built into the contracts your partners use with KOLs on your behalf.

Enforcement: How China Actually Polices KOL Advertising {#enforcement}
Enforcement of advertising compliance in China is not theoretical. Since 2021, SAMR has conducted multiple nationwide campaigns specifically targeting false or undisclosed influencer advertising, and individual cases have been publicized as deterrents to broader market behavior.
Xiaohongshu itself has its own active enforcement mechanism. The platform routinely removes content flagged as "fake grass-planting" — posts that present paid placements as organic recommendations — and accounts that repeatedly violate disclosure policies can face permanent suspension. In 2021, Xiaohongshu publicly removed over 300 influencer accounts as part of a platform-wide cleanup of fake review content, sending a clear signal about enforcement intent.
For international brands, enforcement risk is heightened in high-profile product categories including luxury goods, baby and child products, health and wellness, and anything making efficacy claims. Brands that have invested significantly in building a presence on Xiaohongshu or other Chinese platforms should treat compliance as a continuous operational responsibility, not a one-time check before campaign launch.

Practical Compliance Checklist for International Brands {#compliance-checklist}
Pulling the legal requirements together into operational practice, here is a working compliance checklist for international brands planning KOL campaigns in China:
• Confirm that all sponsored posts will carry appropriate disclosures ("广告" or "品牌合作") in a prominent position.
• Use Xiaohongshu's Brand Partner Platform for all paid partnerships on that channel.
• Review all content briefs for superlative language, medical or health claims, and before-and-after comparisons before briefing KOLs.
• Include compliance clauses in all KOL contracts or agency agreements.
• Obtain pre-publication content approval for posts in regulated categories (beauty/skincare, food, health, mother and baby).
• Ensure KOLs have genuinely used the products they endorse.
• Maintain documentation of all commercial arrangements with KOLs in case of regulatory inquiry.
• Monitor published content after launch to confirm disclosures remain visible and claims remain accurate.
If you are working across multiple platforms simultaneously — for example, running coordinated campaigns on Xiaohongshu and Douyin — note that each platform has its own disclosure mechanism and the same content must be adapted to meet each platform's specific requirements.
Conclusion {#conclusion}
China's KOL marketing regulations are detailed, actively enforced, and evolving. For international brands, the complexity is compounded by the gap between Western advertising norms and what Chinese law actually requires. Disclosure obligations are broader than most brands assume, the list of prohibited claims is longer than most briefs acknowledge, and platform-specific rules add another layer of requirements on top of national law.
The good news is that compliance and effective KOL marketing are entirely compatible. Brands that invest in building clean, transparent, well-structured influencer programs on platforms like Xiaohongshu consistently find that Chinese consumers respond well to authentic, properly disclosed content. Regulatory compliance is not a constraint on creativity — it is the foundation for long-term brand trust in the China market.
