Sensor Tower: Temu cut US digital ad spending by an estimated 31% and Shein by 19% in the two week period from March 31 as the de minimis exemption is closed
For Meta, Alphabet and other platforms, the elimination of the tariff exemption for inexpensive goods is already cutting into advertising revenue.
Context & Ripple Effects
Temu and Shein had been unusually large buyers of US digital advertising, with prior coverage documenting their multibillion-dollar campaigns across major platforms. This makes their pullback a meaningful test of how trade-policy changes can reach platform revenue through advertisers’ underlying economics.
The spending cuts were an early indicator: subsequent Sensor Tower coverage recorded steep declines in Temu’s US daily users and both companies’ US daily audiences. At the same time, higher April ad spending in France and the UK suggests the adjustment was geographically uneven rather than a simple end to promotion overall.
First-order effects
- Temu and Shein immediately reduce paid US customer-acquisition activity, while Meta, Alphabet and other ad platforms lose demand from two previously aggressive retail advertisers.
- The change ties US advertising outlay more directly to the viability of the companies’ low-value cross-border order model after the exemption’s removal.
Second-order effects
- Less bidding from Temu and Shein can ease competitive pressure in US performance-ad auctions, affecting the cost and availability of conversion-oriented inventory for other retailers.
- Their differing international spending pattern means ad platforms may see demand shift across markets rather than disappear entirely, reducing the ability to treat US ad budgets as globally interchangeable.
Third-order effects
- If sustained, this establishes a clearer regulatory transmission channel: trade rules can reshape digital-ad revenue by changing whether merchants can profitably fund customer acquisition.
- The broader risk for ad platforms is greater concentration of commercial-intent demand among business models less exposed to changes in cross-border trade policy.
The trend: This is one data point in the growing linkage between regulation of cross-border commerce and the demand economics of performance advertising.
