If you’re someone who loves shopping online for deals, you might want to keep an eye on your cart total. President Trump’s recent trade policies could make those bargains a bit pricier.

One of the key changes in his latest executive order impacts how goods bought online from platforms like Amazon, Shein, and Temu are taxed when they enter the U.S. This shift could affect more than 80% of e-commerce imports, potentially increasing costs for customers.

At the heart of the change is something called the “de minimis exception.” This little-known rule allowed certain low-value packages—those under $800 per recipient per day—to enter the U.S. without tariffs. It’s been a big win for companies, especially Chinese vendors, who’ve used it to ship affordable products directly to consumers.

But Trump’s order scraps this exemption, meaning those small, everyday purchases might now come with additional fees. This move could shake up the online shopping scene, particularly for platforms like Shein and Temu, which have grown quickly by offering budget-friendly items.

Critics of the de minimis rule have long argued it has downsides beyond trade. They say it’s also made it easier for illegal drugs and related materials to slip into the country unnoticed, since these shipments require less scrutiny from customs.

The de minimis exemption dates back to a century-old trade law meant for minor shipments. But as online shopping has exploded, so has its use. Now, with Trump’s new policy, the game is changing—and your next online haul might cost a bit more.

So, before you click “buy,” it might be worth checking if that deal is still as sweet as it looks.
