On the third day of Prime Day, most sellers' mentality has shifted from "racing out of the gate" to "fatigue from chasing volume"—ad budgets are growing thicker, but conversion rates are starting to dull. However, experienced operators are well aware of a pattern: the real explosion point of a major promotion is never sales volume, but rather risk control suddenly tightens on the 3rd-4th day. Amazon officially upgraded its compliance policy on July 13, 2024, requiring test reports to come from platform-approved laboratories, otherwise they are considered invalid, with children's products, electronic devices, and medical equipment being the first to be affected; some high-risk categories on the US site (electric transportation equipment, dietary supplements, ophthalmic drugs, skin whitening) also forcibly enabled the TIC institution "direct verification" mechanism, sellers cannot upload reports on their own. During Prime Day, the greater the traffic, the frequency and strictness of this risk control AI scan will be doubled compared to normal, and the third day is exactly at the node of "traffic peak + system full review".

During these three days, three types of risks are rising simultaneously

The first type: "Settling accounts after autumn" for product compliance documents. CE (EU), FCC/UL/CPC (US), FDA filings, when sales are low during normal times the platform is too lazy to check, but as soon as Prime Day sales soar, the probability of spot checks immediately rises. Third-party monitoring data in 2023 showed that over 120,000 ASINs were removed due to lack of UL, concentrated among sellers of sockets and extension cords in Shenzhen and Dongguan; in Q1 2024, more than 3,000 sellers were frozen for using "shadow reports" (unauthorized institutions imitating UL templates). Since 2023, the EU has required CE technical documents to upload the EC DoC, circuit diagram, BOM list, test report four-piece set, and in the 2026 Prime Day preparation list, GPSR, battery regulations, EPR, German Packaging Law, WEEE are also must-check items for European sites.

The second type: Listing exaggeration is marked in batches by AI. Amazon's official notice in January 2026 for global stores is very clear—disease claims (cure, relief, treatment, prevention) must be pre-approved by the FDA, otherwise they are handled according to the "Misleading Statements and Prohibited Statements Policy"; the platform removed over 120,000 suspected false advertising ASINs just in July 2025, "98% cure rate", "3 days whitening", "national patent (without patent number)" are all high-frequency landmines. Even words like "possibly" and "helpful", which are mitigating, cannot escape the burden of proof.

The third type: The probability of misjudging category-sensitive words has increased sharply. During major promotions, descriptive regular words like "Gift", "Free", "Warranty" will be batch-scanned by AI as "listing policy violations"; words like antibacterial, antifungal, insect repellent, disinfection, anti-mold, if not EPA certified, will be directly judged as restricted goods such as pesticides/insecticides; absolute commitments like "100% effective", "lifetime warranty", "guarantee", as well as words guiding reviews like "review/feedback/rating", are also on the high-risk list.

Typical misconception: Keep adding ads as long as it can still sell

Many sellers' muscle memory on the third day is—ACOS went up? Increase budget. Conversion dropped? Change words and reinvest. But the outbreak pattern of compliance issues is precisely "the higher the traffic, the easier it is to explode": if a high-conversion ASIN is marked by the system on the third day with a "product compliance request", files must be supplemented within 7/30/60 days, otherwise FBA inventory is directly unsellable; if it hits a sensitive word removal + review for 3-5 days, it just misses the entire Prime Day tail peak. More subtly, ASIN weight damage—once the account status rating (AHR) is marked as "unsolved policy violation", the subsequent recovery cycle is generally 1-3 months, and the violation record is retained for a long time.

Three things you can still do on the third day

• Brush the backend "Performance Notifications" + Account Status Rating page at least once a day, compliance spot check emails usually land here first, not internal messages, don't miss them.

  
  

• Do a "static review" of the details page of high-conversion ASINs: go through the five points, A+, backend Search Terms, image watermarks, video subtitles line by line, and self-inspect words like "Gift/Free/Warranty/Antibacterial/100%/FDA/EPA" first, especially be careful of malicious implantation by competitors.

  
  

• Don't touch sensitive attributes from the third day onwards—title word changes, category migration, image replacement, these actions themselves will re-trigger AI scans, "suicidal optimization" halfway through a major promotion is more dangerous than no optimization.

  
  

Prime Day is about growth, but it's even more about whether you're still there after the tide of traffic recedes. Account suspension never starts from the first day, but from the moment you think it's "still sellable" on the third day.
