For decades, any package worth $800 or less could enter the U.S. duty-free, no paperwork, no questions. That rule was called “de minimis,” and it’s the reason a $15 shirt ordered from overseas could show up at your door with no added fees. That exception is now gone, and a government bulletin released this week, CSMS #69289734, is the last technical step in making its disappearance permanent.
Here’s what it actually says, and what it means for shoppers, small businesses, and the mail system carrying all of this.
What the Bulletin Says
U.S. Customs and Border Protection (CBP) is building a new filing category, “Entry Type 13,” inside ACE (the government’s system for processing imports). It’s built specifically for international mail, separate from cargo shipped by truck, ship, or courier. Software companies and customs brokers can start testing it July 24, 2026. It goes live for real packages September 22, 2026.
The rule hasn’t changed. What’s changing is the machinery built to enforce it, now scaled to handle mail volume that never used to touch customs at all.
The Bigger Story Behind It
This bulletin is the tail end of a policy chain over a year in the making. An executive order suspended the $800 exemption worldwide in July 2025, effective that August. A second order extended the suspension in February 2026. A law passed by Congress in mid-2025 kills the exemption permanently, effective July 2027. On June 24, 2026, CBP made it official at the regulatory level, formally suspending the old exemption and creating a new process specifically for mail.
That new process takes effect July 24, 2026, the same day the new system opens for testing. Here’s how it works: for packages worth $2,500 or less, the buyer, seller, or a licensed customs broker has to report the shipment to CBP monthly, with a precise tariff code, and pay whatever duty is owed through a government payment portal. That replaces the old, informal approach, where a mail carrier might collect cash at the door if a package happened to get flagged. Goods facing anti-dumping penalties or import quotas are excluded and require full formal customs filing instead, with a four-month grace period to transition.
What It Means If You Order Things Online
The exemption already ended in practice, in August 2025. This system doesn’t undo that. It’s an attempt to make the enforcement consistent instead of chaotic.
Last August, the technical instructions for collecting duty arrived only two weeks before the deadline. More than 30 countries, including Japan, Australia, the U.K., and India, simply stopped shipping packages to the U.S. rather than risk breaking the new rules, and international mail volume into the U.S. dropped more than 80% almost overnight. This new system is CBP’s attempt to build the infrastructure that should have existed the first time, so duty gets calculated and billed in an orderly way, ideally folded into the checkout price, rather than showing up as a surprise or getting a package stuck for weeks. Whether that works depends on whether postal services and CBP’s own systems are actually ready by September.
Why this Changes the Shopping and Shipping Landscape
The $800 exemption wasn’t a minor loophole, it was the foundation an entire retail model was built on. Package volume using it grew from about 134 million a year in 2015 to over 1.36 billion by 2024. Shein and Temu alone are estimated to have accounted for roughly 30% of everything shipped under it at its peak, a business model built entirely on treating each package as small, informal, and untaxed rather than as commercial cargo.
That distinction is gone. Mail now runs through essentially the same customs rules as any other import, with a lighter paperwork process rather than an exemption. That reaches beyond Chinese shopping apps, touching independent sellers on Etsy and eBay, overseas manufacturers who used to ship straight to American customers, and any business whose model assumed packages could move cheaply and quietly across the border.
Where this is Likely Headed
The direction is clear: fewer exemptions, more reporting, on smaller shipments over time. Since the law wipes out the exemption entirely by July 2027, the $2,500 threshold here is likely a bridge, not a permanent ceiling, and probably tightens as that deadline approaches. Expect a growing industry of software providers, brokers, and shipping specialists built around helping small businesses handle this reporting, since most don’t have the staff to do it themselves. This isn’t only a U.S. story, either: the EU is rolling out its own flat fee on small parcels in July 2026, suggesting these exemptions are closing globally, not just at U.S. borders.
Who gets Squeezed Hardest
Large platforms like Shein and Temu can absorb this, hire compliance teams, or restructure how they ship. Small businesses generally can’t. Under the new system, a small importer now needs a customs bond on file, has to classify every product to a precise tariff code, and has to manage a monthly payment cycle, real cost and real work for businesses that never had to think about tariff classification before. Early estimates put the cost of the broader exemption rollback at over $10.9 billion to American consumers, or roughly $136 per family, and that cost moves backward through small sellers before it reaches anyone’s cart.
Postal services face the same squeeze at a larger scale. USPS and its counterparts abroad are being asked to become customs processors almost overnight, verifying data and supporting broker relationships for volumes that used to move with minimal paperwork. The August 2025 shutdown, when dozens of countries paused shipping rather than risk getting it wrong, was a preview of what happens when that infrastructure isn’t ready. This system, tested in July and live by September, is the attempt to get the plumbing right before the exemption disappears completely in 2027. Whether postal services trust it enough to fully resume normal shipping will be the real test of whether this quiet technical announcement succeeds where last year’s abrupt policy change didn’t.
