China E-Commerce Update: Platform Advertising Filing Requirements Expanded to All Categories — Key Takeaways

As of March 15, 2025, China’s State Administration for Market Regulation (SAMR) 市场监管总局 (shìchǎng jiānguǎn zǒngjú) has expanded mandatory advertising filing requirements under the Internet Advertising Management Measures (IAMM, 互联网广告管理办法, hùliánwǎng guǎnggào guǎnlǐ bànfǎ) from 12 priority categories to all 28 e-commerce product categories, directly affecting an estimated 5.2 million active sellers on platforms including Alibaba (BABA:NYSE), JD.com (JD:NASDAQ), and Pinduoduo (PDD:NASDAQ).

This regulatory shift marks the most sweeping change to China’s online advertising compliance framework since the original IAMM took effect in May 2023. Previously, only categories such as healthcare, finance, food, and cosmetics required pre-publication filing of advertising content with platform operators. Now, every seller — from consumer electronics to apparel, home goods to pet supplies — must file product claims, promotional copy, and comparative statements for review before going live.

The announcement came with a 60-day grace period ending May 14, 2025, during which platforms must update their systems and sellers must submit outstanding filings. Penalties for non-compliance have also been sharpened: first violations carry fines of RMB 200,000 to RMB 1,000,000, while repeat offenses can reach RMB 3,000,000 plus potential platform delisting. For cross-border e-commerce (跨境电商, kuàjìng diànshāng), the expansion is particularly disruptive — an estimated 73% of cross-border sellers must now file, compared to just 34% under the previous rules.

What the Expanded Filing Requirement Entails

Under the updated IAMM enforcement guidelines, every piece of advertising content published on a Chinese e-commerce platform must undergo a formal 广告审查 (guǎnggào shěnchá, advertising review) process. This includes product titles, bullet-point descriptions, promotional banners, short-video scripts, livestream scripts, and influencer endorsement copy. The platform operator is responsible for verifying that each submission complies with China’s Advertising Law and the IAMM.

The key procedural change is that filing is now continuous and not event-based. Previously, sellers submitted ads per product launch or promotional campaign. Now, all existing listings must be audited and refiled by May 14, 2025, and any subsequent change to a listing — even a price drop or a new adjective — triggers a fresh filing requirement within seven days.

Platforms are required to maintain a publicly accessible archive of filed ads for at least three years. This creates an audit trail that SAMR can inspect at any time. Sellers who fail to file or who file inaccurate content face escalating penalties, as outlined in the table below.

For foreign brands operating WFOEs (外商独资企业, wàishāng dúzī qǐyè) or using cross-border direct sales (跨境直购, kuàjìng zhígòu), the expansion means that nearly all product advertising must now pass through a local platform’s review process. Previously, many international brands relied on exemptions for “non-PC (personal care) and non-medical” categories. That exemption has been all but eliminated.

Timeline and Enforcement: From Announcement to Full Enforcement

The SAMR’s announcement on March 15, 2025, gave platforms and sellers a 60-day grace period — until May 14, 2025 — to achieve full compliance. During this window, platforms must update their ad-filing interfaces, train review teams, and communicate new requirements to sellers. Sellers must audit all existing listings, submit filings for any unapproved content, and implement processes for continuous compliance.

Phase 1 (March 15 – April 15): Platforms complete system upgrades. Sellers receive notification and must begin auditing their top 20% of listings by revenue. Phase 2 (April 15 – May 14): All remaining listings must be filed. SAMR conducts random spot checks. Phase 3 (May 14 onward): Full enforcement begins. First offenders receive warnings and fines; repeat offenders face platform delisting and potential business license suspension.

Cross-border sellers face an additional layer of complexity. Under previous rules, goods sold through bonded warehouses (保税仓, bǎoshuì cāng) or direct mail (直邮, zhíyóu) were often exempt from domestic advertising review, as long as the product claims matched the original overseas labeling. Now, those same claims must pass through the platform’s 广告审查 process. For example, a supplement sold via Tmall Global that previously used FDA-disclaimer language in English must now file a Chinese-language version that passes China’s strict health-claim standards, which often prohibit efficacy statements that are legal in the U.S. or EU.

The timeline is aggressive, and enforcement expectations are high. SAMR officials have publicly stated that platform accountability is a priority — platforms that fail to enforce filing requirements will face fines equivalent to 1–3% of their annual e-commerce advertising revenue. For major platforms, that could translate into billions of RMB in penalties.

Impact on Cross-Border E-Commerce and Foreign Brands

The expanded filing requirement disproportionately affects foreign brands, particularly those in categories previously considered low-risk. For example, a German kitchen-knife brand selling on JD Worldwide previously did not need to file advertising copy for its “German engineering” claims. Now, those claims require documentation — such as a certificate of origin or a recognized testing report — filed with the platform before the ad can go live.

Similarly, a French skincare brand that used terms like “anti-aging” or “clinically proven” in its product descriptions must now file clinical-trial data or third-party test results as part of the 广告审查 process. If the claims cannot be substantiated under Chinese regulations, the ad must be rewritten — a significant operational burden for brands with multilingual, multi-jurisdictional marketing teams.

For foreign brands entering China for the first time, this regulation adds a new layer of market entry compliance. Beyond product registration, trademark filing, and customs clearance, advertising content must now pass platform-level review before any listing goes live. Brands that fail to budget for this compliance cost — both in time and legal fees — risk launch delays and lost sales during peak seasons like Singles’ Day (双十一, shuāng shíyī) or the 618 Shopping Festival (618购物节, 618 gòuwù jié).

One common workaround being discussed among cross-border sellers is to use third-party advertising compliance agencies that specialize in Chinese platform regulations. These agencies pre-approve ad copy, maintain archives, and handle re-filing when listings change. While this adds an estimated RMB 30,000–80,000 per brand per quarter in operational costs, it significantly reduces the risk of non-compliance penalties.

The SAMR has also signaled that it will increase enforcement of influencer and livestream advertising, which accounts for an estimated 18% of all e-commerce ad spend in China. Under the expanded rules, any livestream script that makes a product claim — including verbal claims by the host — must be filed in advance. Platforms must record livestreams and store transcripts for the three-year archive period. For brands using key opinion leaders (KOLs, 关键意见领袖, guānjiàn yìjiàn lǐngxiù), this means tighter control over live content and potential liability if the host makes an unapproved claim.

NEXT STEPS

1. Audit your current listings immediately. Review all product titles, descriptions, promotional banners, and livestream scripts for claims that may require substantiation. Start with your top 20% of revenue-generating SKUs. Use our Market Entry Compliance Checklist to identify high-risk claims.
2. Set up a continuous filing process. Assign a team member or partner to manage submissions for each platform. Implement a 7-day internal review cycle for any listing changes. Read our Guide to E-Commerce Registration and Filing for step-by-step workflow templates.
3. Engage a local compliance partner. Consider contracting a Chinese advertising compliance agency or a law firm with SAMR expertise. Budget RMB 30,000–80,000 per quarter. Explore our Compliance Support Services for pre-vetted agency recommendations.
