🔴 Key Focus

Amazon Association Suspension Emails No Longer Show Store Names, Sellers Left Completely Blind in Investigations

Amazon will no longer display the names of associated stores in their account suspension notices. This change leaves sellers unable to identify the linked accounts, dramatically increasing the difficulty of investigation and appeals, and making account recovery almost a shot in the dark. All multi-store operators should immediately conduct internal compliance checks, strictly adhere to anti-linkage measures, avoid any actions that could lead to associations, and organize independent operation evidence for each store to prepare for unforeseen circumstances.

TikTok Shop Smart Promotion Charges Sellers 3.5% of GMV

TikTok Shop has completely overhauled its promotion fee model, shifting from a shared platform-seller burden to a fixed seller rate: 3.5% of Gross Merchandise Value (GMV) for regular promotions and up to 4.5% during big sales. This will significantly increase sellers' marketing costs. Sellers must immediately factor this new fee into their profit models, re-evaluate the ROI of promotions, and adjust pricing or promotional strategies to maintain healthy margins.

U.S. Indefinitely Suspends De Minimis Exemption for Non-Postal Channel Packages Under $800

U.S. Customs has announced the indefinite suspension of de minimis tariff exemption for imported goods valued at $800 or below through non-postal channels (such as commercial couriers), requiring formal customs entry. This will increase costs and clearance times for small-package direct shipping. Affected sellers should immediately assess the feasibility of switching to postal channels (e.g., USPS) or consider establishing U.S. overseas warehouses to import in bulk and ship locally, mitigating the risks of small-package policies.

⏰ Effective Immediately

Singapore Strengthens Regulation on Cross-Border Online Appliance Sales from July 1, Mandating MEPS and COR Registration

Starting July 1, Singapore will enforce mandatory Minimum Energy Performance Standards (MEPS) and Certificate of Registration (CoR) for electrical appliances sold cross-border through e-commerce platforms. Products without valid certificates may be denied entry and seized by customs. All sellers in relevant categories must verify if their products are listed, coordinate with suppliers for testing and registration, and ensure compliance before July 1.

Amazon Pushes Sellers to Take Sides? Warning Letters Force "Choose One or the Other"

Amazon has sent warning letters to third-party sellers, explicitly requiring them not to sell the same products at lower prices on competitor platforms, effectively creating an exclusive "choose one or the other" demand. Non-compliance may lead to product delisting or account restrictions. This poses huge risks for multi-platform sellers; they are advised to carefully review pricing strategies across channels, assess dependency on a single platform, and prepare alternative plans in advance.

💡 Today's Insight

Today's news highlights three major trends: first, tightening platform rules around major sales events (Amazon association bans, TikTok fees, livestream restrictions); second, rapidly tightening and immediately effective compliance requirements (Singapore appliances, U.S. parcel exemption removal); third, increasing exclusivity conflicts in multi-platform operations. The core action for sellers now is to conduct a thorough "compliance cleanup" — scrutinize all stores' operations, pricing, and supply chain activities to eliminate all potential risk points; simultaneously, actively reduce dependence on a single platform by expanding regional markets or building independent sites to hedge against policy risks.
