Temu and SHEIN have spent the past four months quietly retreating from one of their most important advertising channels in Europe. According to data published by Smarter Ecommerce (smec), the percentage of a sample of roughly 500 European Google Shopping advertisers facing account-level competition from Temu has fallen by around half since March 2026. SHEIN's decline is steeper still: the same dataset shows the company's presence in Shopping auctions dropping close to zero by late June, a level the smec analysis describes as nearing a total exit from the channel.

The retreat did not happen overnight, and it did not happen without warning. It tracks a legal deadline that has been on the calendar since November 2025, when EU finance ministers agreed to eliminate the bloc's long-standing customs duty exemption for low-value parcels. That agreement became law on July 1, 2026, when the European Union today replaced the duty-free threshold for packages worth less than €150 with a flat €3 charge applied per item. For companies whose entire commercial model depends on shipping millions of small, individually addressed parcels directly from Chinese warehouses to European doorsteps, the fee is not a rounding error. It is, according to smec's analysis, roughly equivalent to a 10 percent tariff on a typical €30 order, since the charge is assessed per tariff classification within a shipment rather than per parcel.

Mike Ryan, Head of Ecommerce Insights at Smarter Ecommerce, framed the timing bluntly in the company's June 17 blog post explaining the data: "Their target: the deluge of cheap goods unleashed by Chinese warehouses, propagated by marketplaces, gamified by apps, multiplied by algorithms, and perfected by vast economies of scale." Ryan also noted that advertising, in this specific case, functions as an unusually reliable leading indicator of a shipping decision made weeks earlier, since a Chinese merchant's parcel might spend days or weeks in transit before it reaches an EU border checkpoint that will assess it under the new rules.

Why advertising moves first

The mechanics behind that leading-indicator effect become clear once laid out. Customs enforcement does not care when a consumer placed an order or when a warehouse dispatched it; it cares only about the date a parcel physically crosses into the EU. Because Chinese cross-border shipping times commonly run from several days to a few weeks, any order placed close to the July 1 enforcement date carried meaningful risk of arriving after the rules changed, and thus of being hit with a duty charge that had not been priced into the original sale. Retailers who understood this exposure had a simple lever available to them: reduce the volume of new orders being generated through paid channels, and reduce the risk of a customs surprise landing on either the seller's margin or the buyer's doorstep.

Google Shopping, in particular, functions for these companies as something closer to a demand faucet than a branding channel. It operates largely as a price-comparison surface, a format that plays directly to the strengths of a consumer-to-manufacturer, or C2M, retail model built around stripping out the traditional Western retail middleman and passing the resulting cost savings straight to shoppers. When Temu, SHEIN, or AliExpress want to slow the rate of new orders flowing toward the EU border, throttling Shopping ad spend is one of the fastest levers available, since it directly controls the top of the demand funnel rather than requiring a change to pricing, logistics, or product listings.

The data behind the pullback

The smec chart tracking this shift plots the percentage of advertisers facing account-level competition from each of three companies, Temu, SHEIN, and AliExpress, across a window running from early May through late June 2026. All three lines begin the period at broadly comparable levels: Temu holding a share in the mid-70s percent range, and SHEIN somewhat lower but still substantial, both fluctuating within a relatively narrow band through most of May. The pattern then diverges sharply. Temu's line declines gradually but steadily through late May and into June, closing the period at roughly half its opening level. SHEIN's line, by contrast, holds relatively flat through late May before dropping abruptly to near-zero at the very end of the month, and remains at that depressed level through the close of the observation window in late June.

The pattern's most counterintuitive detail concerns the third company in the dataset. Rather than mirroring Temu and SHEIN's retreat, AliExpress increased its Shopping presence over the same window, closing in on Temu's declining share by late June. Ryan's own analysis treats this divergence with some caution, describing it as a company potentially attempting to capture as much remaining revenue as possible before the July 1 deadline takes effect, a strategy the smec post characterizes as "a dangerous game" given that any parcels still in transit toward the deadline face the same customs exposure as Temu's and SHEIN's.

The smec sample itself carries an important caveat that shapes how the figures should be read. The roughly 500 advertisers tracked are described as an exemplary group rather than an exhaustive one, meaning the visible pullback likely understates the true scale of the shift once smaller Chinese C2M and drop-shipping merchants, who are not individually captured in the sample, are taken into account.

What the €3 charge actually covers

The mechanics of the new EU duty explain why the incentive to pull back on advertising ahead of July 1 was so strong. Under the reformed rules, the €3 charge is not levied once per parcel but once per distinct tariff classification contained within that parcel. A single package containing a dress, a phone case, and a USB charger, three separate product categories under three separate customs codes, would generate three separate €3 charges rather than one, pushing the total duty on that shipment to €9. Because platforms built around bundling multiple low-cost items into a single order, partly to clear existing free-shipping thresholds, this per-line-item structure scales the cost impact upward in ways a flat per-parcel fee never would have.

The scale of the underlying trade volume helps explain why EU policymakers moved on the issue at all. Nearly 5.9 billion duty-free items entered the European Union from third countries in 2025, according to figures cited in prior PPC Land reporting on the customs reform. A 2025 EU-wide investigation cited in that same reporting found that more than 60 percent of low-value goods entering the bloc failed to comply with product safety or regulatory requirements, giving the reform a consumer-protection rationale that ran alongside its trade-fairness one. Maroš Šefčovič, the European Commissioner for Trade and Economic Security, has previously summarized the policy's intent as bringing the customs system in line with "open market, equal rules."

Wednesday's enforcement date is explicitly framed as a transitional step rather than the reform's end state. The €3 flat rate is scheduled to remain in place only until July 2028, at which point the EU Customs Data Hub is due to become operational and full, classification-based customs duties, calculated according to a product's tariff heading, country of origin, and declared value, will take over from the current flat-fee arrangement. A separate, smaller step arrives sooner: a voluntary phase for declaring product identifiers began alongside the July 1 duty, with that declaration becoming mandatory across the bloc no later than November 2026, giving sellers, marketplaces, and customs brokers a roughly four-month window to adapt their data systems.

A market vacuum with an early claimant

If the retreat by Temu and SHEIN opens a gap in Google Shopping's competitive landscape, that gap is not staying empty for long, and one competitor in particular has moved with unusual speed to fill it. Amazon Prime Day 2026 ran from June 23 through June 26, according to the confirmed schedule spanning 26 countries, placing the promotional event squarely inside the same window in which Temu and SHEIN's Shopping ad presence was collapsing. The overlap was not incidental to Amazon's planning. As smec's analysis put it, "Amazon will be peaking their budgets around the same time many of these Chinese advertisers go dark," a dynamic the post frames as a rare opportunity for advertisers positioned to capture demand in categories where Chinese C2M sellers had previously dominated on price alone.

The Prime Day timing itself reflects a broader shift in Amazon's promotional calendar. This year's event marked only the second time since Prime Day's 2015 debut that the sale ran in June rather than its traditional July slot, a scheduling change first flagged by industry speculation in February 2026 and confirmed by Amazon on April 29. The earlier date compressed inventory and marketing lead times for third-party sellers preparing for the event, but it also positioned Amazon's heaviest promotional spending to land at precisely the moment competitive pressure from Chinese marketplaces in Google Shopping auctions was easing.

Whether that vacuum gets filled by Western retailers more broadly, rather than by Amazon alone, remains an open question. The smec analysis is careful to note that the opportunity exists for any advertiser willing to increase budgets and relax efficiency targets in categories where Temu, SHEIN, and their peers had previously exerted the strongest downward pressure on cost-per-click. Whether independent merchants move quickly enough to capture that space before AliExpress, still expanding its own Shopping presence as of late June, or a returning Temu and SHEIN reclaim it once their businesses adjust to the new duty structure, is a question the data available so far cannot answer. The auction has already shown how fast a new entrant can establish itself once it decides to compete: a fourth Chinese-linked platform quietly bought its way into the same Shopping auctions weeks before its European launch was even publicly announced.

The UK's different clock

Not every major European market faces the same July 1 deadline, and that asymmetry carries its own consequences for advertising budgets. The United Kingdom operates a separate de minimis regime from the EU's, with a threshold currently set at £135 for duty-free entry of low-value imports. The UK Chancellor confirmed in the Autumn 2025 Budget that this threshold will eventually be phased out, but the government's own timeline sets a target of March 2029, roughly two and a half years after the EU's reform takes effect. That gap leaves the UK as one of the last major Western markets still permitting the kind of de minimis structure that both the United States and the European Union have now closed.

The practical consequence, for advertisers and retailers watching the space, is that Chinese sellers facing shrinking margins in continental Europe retain a nearby market where the previous economics still largely apply. Whether that leads to a meaningful reallocation of advertising budgets toward UK-facing Shopping campaigns is not something the current smec dataset addresses directly, since its sample is described as covering European advertisers broadly rather than isolating UK-specific competitive dynamics. It is, nonetheless, a structural feature of the current moment: three major Western economies, the United States, the European Union, and the United Kingdom, are now moving through de minimis reform at three distinct speeds, with the UK trailing by years rather than months.

A precedent from across the Atlantic

The pattern of Chinese platforms suddenly and dramatically reducing paid advertising spend in response to de minimis policy changes is not new to 2026. Temu offered an earlier and more abrupt version of the same playbook in the United States roughly fourteen months prior. Following the Trump administration's executive order suspending America's de minimis exemption, an order signed July 30, 2025, and taking effect August 29 of that year, Temu completely halted all Google Shopping advertising in the United States on April 9, 2025, months ahead of the US policy's actual implementation date. The consequences for the company's visibility were immediate and severe: Temu's ranking in the US App Store fell from a consistent top-five position to 58th place within three days of the advertising pullback, according to data reported at the time.

That episode differs from the current European retreat in one important respect. The US withdrawal was near-instantaneous, a full shutdown executed within a matter of days once tariff pressure intensified. The European pullback documented in the smec data, by contrast, has unfolded gradually across several months, with Temu's decline tracking a steady downward slope rather than a cliff, and SHEIN's collapse arriving as a sharper but still distinctly separate drop concentrated at the very end of May. Whether this slower pace reflects a more considered response by companies that had already absorbed the lesson of the earlier US experience, or simply the different mechanics of a fee structure phased in through a known legislative date rather than an abrupt executive order, is not something the available data resolves conclusively.

Summary

Who: Temu and SHEIN, two Chinese-founded e-commerce platforms operating across Europe, along with Smarter Ecommerce (smec), the Austria-based PPC software and agency firm whose Google Shopping data documents the advertising pullback, and the European Union, whose customs reform is the policy driver behind it.

What: Google Shopping data covering roughly 500 European advertisers shows Temu's account-level competitive presence in the auction falling by around half since March 2026, while SHEIN's presence has dropped close to zero over the same period. The pullback precedes the EU's July 1, 2026 elimination of its €150 de minimis customs exemption, replaced by a flat €3 duty charged per item within a parcel.

When: The advertising decline began in March 2026 and intensified through late May and June, with smec publishing its analysis on June 17, 2026. The underlying EU customs reform took effect on July 1, 2026.

Where: The data covers Google Shopping auctions across European Union member states. A separate United Kingdom de minimis threshold, currently set at £135 and not due to be phased out until March 2029, remains unaffected by the EU's July 1 reform.

Why: The €3 per-item duty, equivalent to roughly a 10 percent tariff on a typical €30 order according to smec's analysis, undermines the low-cost, high-volume shipping model that Temu and SHEIN built their European businesses around. Because customs enforcement is triggered by a parcel's arrival date rather than its order date, and Chinese cross-border shipping commonly takes days to weeks, reducing new order volume through advertising became one of the fastest available levers to limit exposure to the new fee ahead of the July 1 deadline.
