🔴 Key Focus

EU July 1 tariff new rules landed, logistics companies collective warning

The EU new tariff policy has been effective since July 1, but recently multiple cross-border logistics companies have issued warnings centrally, showing implementation issues still fermenting: customs clearance delays, cost accounting complexity greatly increased. Sellers need to immediately check applicable tax rates for each SKU in each EU destination country, recalculate total landed cost and adjust pricing, and prepare compliance documents such as product description, HS code and certificate of origin to avoid goods being withheld or fined due to inaccurate declaration.

⏰ Already in effect, recommend completing all SKU tax rate checks within this week

Amazon warning letter asks sellers to "choose one"

Amazon sent warning letters to some multi-channel sellers who also operate on Temu and other platforms, asking them to stop selling on competing platforms, otherwise they may face penalties. This directly affects channel strategy and revenue structure of multi-platform operating sellers, especially in the context of rapid growth of TikTok Shop and Temu, the hidden cost of being forced to "choose sides" is extremely high. Recommend immediately checking registered email and performance notifications to assess whether own accounts are at risk of pressure; if warning received, do not reply rashly, keep all written records and consult professional lawyer or compliance advisor as soon as possible.

⏰ No clear deadline, but need daily email monitoring

Amazon returns add rating mechanism, return experience directly tied to performance

Amazon embeds buyer rating mechanism in return process, meaning return handling quality will directly affect seller performance and even product exposure. Concentrated bad reviews will quickly lower store weight, particularly impacting high return rate categories. Recommend immediately: ① reorganize return communication templates to ensure after-sales response speed; ② add quality inspection and packaging reinforcement for high return rate SKUs; ③ proactively provide clear operation instructions on return page, turning "passive beaten" into "active management".

⏰ Testing in progress, recommend completing return process self-check within two weeks

Amazon product rating display adjusted, conversion logic changes

Amazon adjusts product rating display mechanism, rating is no longer the only prominent basis for consumer decision-making, conversion rate may fluctuate in short term. For new products and small sellers, this is a window period—declining rating weight means content quality and trust elements gain weight. Recommend immediately checking product pages: ① ensure main image and A+ content information complete; ② frontload core selling points and qualification certifications in five bullet points; ③ use brand story and Q&A section to supplement trust endorsements, offsetting conversion impact from rating changes.

⏰ Started rolling out gradually, recommend completing all core ASIN page optimization this week

TEMU all products enforce UK and EU authorized representatives, no authorization means delisting

TEMU requires all products on platform to have UK Responsible Person (UK RP) and EU Authorized Representative (EU AR), products that fail to complete registration or label update will face delisting. This is the most stringent platform-level compliance enforcement after EU GPSR regulation, affecting all TEMU sellers. Recommend immediately checking whether products have appointed authorized representative; sellers who have not done so should start UK/EU representative registration this week (usually 1-2 weeks), and simultaneously update product labels, packaging and instructions to avoid sales interruption.

⏰ Enforced, non-compliant products may be delisted at any time

US tariffs surge 104% plus peer price cuts, three self-rescue paths

US tariffs sharply increased causing import costs to surge, while some peers choose to cut prices to grab share, profit margins squeezed from both directions. Simply raising price loses conversion, enduring losses unsustainable. Three executable paths: ① evaluate overseas warehouse stocking model, pre-position part of inventory, use bulk sea freight to dilute per-unit tariff impact; ② adjust product structure, focus on high customer unit price, high gross margin differentiated SKUs, abandon low-profit volume models; ③ sellers overly dependent on US market should accelerate expansion into Southeast Asia, Europe and other high-potential markets to diversify risk.

⏰ Tariffs already effective, recommend completing supply chain and pricing strategy restructuring within two months

Amazon AI new regulations landed, non-compliance faces penalties

Amazon releases new regulations on AI use, involving AI-generated content review, algorithm tool usage boundaries, etc., violations will face penalties including account restriction. Many sellers use AI to batch generate listings, customer service replies and ad copy, new regulations mean "unthinking AI use" risk surges. Recommend immediately self-check: ① check listings for AI-generated exaggerated or unverifiable functional claims; ② ensure AI-generated images do not involve copyright or false display; ③ add human review process to AI tool output, keep modification records for appeal.

⏰ New regulations released, recommend completing AI content screening within this week

💡 Today's Insight

Today's core contradiction is compliance costs and channel structure restructuring simultaneously: EU tariffs, US de minimis suspension, TEMU UK/EU representative enforcement, three things combined push the old model of "small parcel direct shipping + low-price bulk listing" to the wall. Sellers who continue to cling to a single market and single channel will see profit eroded by compliance costs and tariffs faster than expected. Recommendations: ① complete tariff and compliance cost accounting for all SKUs sold in US and EU markets within this week, proactively cut products that "look profitable but calculate loss"; ② upgrade overseas warehouse stocking from "optional solution" to "strategic standard", prioritize US West / Central Europe nodes; ③ do not put eggs in one basket on Temu or TikTok single platform, Amazon's "choose one" violation risk requires multi-platform operations to be more low-key and dispersed. In the next 90 days, rule dividends belong to those who first complete compliance actions and then set up supply chain nodes.
