Buying products on Shein, Temu, and AliExpress has long been an affordable alternative for millions of users looking for low-priced clothing, technology, or household goods. However, recent changes in import policies in Mexico and the United States are radically transforming the landscape of international online shopping and could significantly increase the cost of products purchased on these platforms.
These new regulations particularly affect those who rely on importing products from countries without preferential trade agreements , such as China, which directly impacts consumers' wallets and the logistics structure of the platforms.
What taxes currently apply to purchases on Shein and other platforms?
Mexico has updated its tariffs on imports from foreign online stores, increasing them from 19% to 33.5% for products arriving from countries like China or those without a trade agreement with Mexico. This measure, announced by the Tax Administration Service (SAT), will take effect on August 15, 2025, and responds to both international pressure and an effort to strengthen domestic industry and increase tax revenue.
The rule only applies to shipments handled by courier companies registered with Mexican customs (for example, DHL, FedEx, or UPS). If you choose an alternative logistics service, such as AliExpress Standard Shipping, you may not be affected by this new tariff for now. To understand how these changes affect the platforms, you can check the impact on Temu and other marketplaces . Conversely, purchases shipped from the United States or Canada maintain preferential tariffs thanks to the United States-Mexico-Canada Agreement (USMCA).
- Less than $50: exempt from tariffs.
- Between $50 and $117: they pay 17%.
- Over $117: 19% tariff.
With the reform, any item from outside the USMCA sent by registered mail will pay 33.5% of its value , with no exceptions for small amounts, representing a considerable tightening of the conditions for importing textiles, electronics and other consumer goods.
The United States closes the door to "de minimis" shipments
In parallel with the Mexican reform, the United States has eliminated the tariff exemption known as "de minimis ." Until now, packages valued at less than $800 could enter the country without paying duties, a tactic that Chinese platforms like Shein and Temu exploited to offer cheap products to American consumers.
Starting August 29, all international shipments will be subject to import duties regardless of their value . For certain countries, tariffs could range from $80 to $200 per item, depending on the origin and existing trade agreements. This measure aims to prevent strategies such as redirecting shipments through third countries to avoid taxes and to curb both product smuggling and tax evasion.
Why are these measures being taken and who do they affect?
Authorities in both countries are seeking to close legal loopholes, protect local industry, and increase control over the entry of low-cost products . In Mexico's case, the tariff increase is also a response to discussions with the United States, which alleges that Chinese companies are using Mexican territory to bring goods into North America, thus avoiding high U.S. tariffs.
The extra cost directly impacts the end consumer , especially those with fewer resources who have found in Shein, Temu, or AliExpress a solution for accessing affordable fashion or technology. Furthermore, the Mexican textile sector, heavily dependent on Chinese imports, feels the effect on its competitiveness and on prices for small retailers.
Current regulations could result in higher prices for previously affordable products, affecting both those who buy for personal use and those who resell merchandise at low prices.
Can the new tariffs be avoided? Tips for online shoppers
Technology platforms could try to circumvent this scenario by modifying their logistics systems, for example, by opting for less regulated shipping methods or establishing partnerships with local distributors. However, there is increasingly less room to evade these tariffs . To better understand how the new regulations affect platforms like Shein, see the rise and controversies in e-commerce in Argentina.
If you're planning a purchase on Shein, Temu, or AliExpress, placing your order before August 15, 2025, could save you from paying the new tax in Mexico. Additionally, it's always advisable to check the product's country of origin and the shipping method to estimate the final cost before confirming your purchase and avoid unpleasant surprises when you receive your package.
Recent tax reforms in Mexico and the United States reflect a trend toward stricter rules for international e-commerce, aiming to control the influx of low-value products, ensure tax revenue, and protect domestic industry. If you want to understand how these changes might affect your finances, review how crises in the tech industry impact consumers . Adapting to these changes will be essential for those who wish to continue taking advantage of low prices from foreign retailers.
