De Minimis Is Dead. The New Postal Entry Rules Hit Today — and Your Per-Entry Math Just Broke

As of today, July 24, the machinery that replaces de minimis is live. U.S. Customs and Border Protection’s new postal informal entry process is in effect, and the comment window on the interim final rule closed this afternoon. If you move parcels — as a broker, a forwarder, a 3PL, or a high-volume e-commerce seller — the way you priced this business no longer holds.

The headline everyone is reading is the one about consumers: the $800 duty-free exemption that let low-value mail into the country untouched is gone, so that $40 order from overseas now carries duty. True, and already priced into the discourse. But the exemption itself was suspended months ago. What actually changed today is the entry process built to handle a world without it — and that process, not the duty, is where the real cost lives.

// What went live

Every qualifying mail shipment valued at $2,500 or less now moves through a formalized informal entry. In practice that means three things that did not exist for these parcels a day ago.

• A customs bond. Filers must post either a single-transaction bond or, for anyone with recurring volume, a continuous basic importation and entry bond under Activity Code 1. For a business processing mail at any scale, the single-transaction option is a fiction; you need a continuous bond, and you need it underwritten.
• A full data set — for every parcel. Filer code, bond number, merchandise description, country of origin, the complete 10-digit HTSUS classification, declared value, duty rate, total duty owed, carrier, conveyance number, tracking number, port of arrival, and arrival date. Submitted on a monthly worksheet, due by the seventh of the month following arrival. This is, line for line, a customs entry’s worth of information. The only thing “informal” about it is the name.
• A licensed filer. Only a party with the right to make entry — the owner, the purchaser, or a licensed customs broker they designate — may file. Foreign postal operators and the unlicensed intermediaries that quietly moved a great deal of this volume are out of the chain entirely.

Duty, for now, runs at 10 percent under Section 122, which carries a 150-day statutory clock. Electronic filing through the Entry Type 13 test begins September 22, and enforcement of the carve-outs — PGA-regulated goods, Chapters 98 and 99, FTA claims — tightens on October 22. CBP projects the change will generate more than $100 million in additional annual duty revenue.

That revenue number is the one getting quoted. It is also the least interesting number in the rule.

// The gut-punch nobody is pricing

Here is the structural problem, and it is an arithmetic one: brokers bill per entry, not per item.

Brokers bill per entry, not per item.

De minimis was not a trickle. It was a river — hundreds of millions of tiny parcels a year, each one previously waved through with almost no processing cost. The new rule takes that river and requires that each drop of it now carry a bonded, 10-digit-classified, fully documented entry. The per-transaction cost of compliance is roughly fixed whether the parcel holds a $30 phone case or a $30,000 industrial part. Spread that cost across a pallet and it disappears into the margin. Spread it across a single low-value package and it is punishing.

This is the premium that the $100 million revenue figure conveniently ignores. The duty is a transfer from importers to the Treasury. The compliance cost is pure friction — new money spent on classification, filing, bonding, and reconciliation that produces nothing but the right to keep moving the goods. And it lands disproportionately, per dollar of merchandise, on exactly the low-value flows that de minimis was designed to keep cheap.

Three pressure points will decide who absorbs it.

Someone has to assign an accurate 10-digit HTS code to every SKU crossing the border by mail. At de minimis volumes, that is not a task, it is an industrial process — and an unforgiving one, because a wrong code is not a rounding error but reclassification exposure and penalty risk. The firms that have invested in classification automation and clean product data are about to find that investment was the whole ballgame. The firms relying on a spreadsheet and a best guess are about to find out what that guess is worth.

Roughly half of the parties eligible to file are already brokers. The other half — importers who leaned on postal operators and never needed a broker relationship — have to establish one, and stand up a continuous bond, before their volume can move. That is a sudden, concentrated demand on surety underwriting. Bond capacity does not materialize overnight, and underwriters are not obligated to extend it to every applicant at a comfortable rate. Expect the surety market, not CBP, to become the near-term bottleneck.

This is the quiet decision that will define the next quarter. Forwarders and 3PLs sitting between the shipper and the consumer now carry a real, recurring, per-parcel compliance cost. They can absorb it and watch it eat a margin that was already thin on low-value freight, or they can pass it through as a line-item surcharge and test how much the shipper — and ultimately the consumer — will bear. Every one of these firms is making that call right now, largely in private, and the aggregate of those calls is the actual story of this rule. It just will not show up in a press release.

// Why it pairs with everything else reshaping low-value trade

None of this sits in isolation. The same policy current that killed de minimis is rerouting how low-value, high-volume goods enter the country across every mode — reclassifying who files, who is liable, and who pays. The postal rule is the piece that hits the informal, consumer-facing end of that flow hardest, because that is where the parcels are smallest and the per-entry math is most brutal. Watch it alongside the broader entry-process changes and a pattern emerges: the era of low-value goods being cheap to process is over, independent of whatever the duty rate happens to be.

// What to watch

CBP will point to $100 million in new duty and call the rule a success. Fine. The more telling numbers will come from the industry: how fast the surety market clears the wave of new bond applications, how many mid-market forwarders quietly add a customs-processing surcharge over the next few weeks, and how many low-value cross-border SKUs simply stop being economical to ship at all.

De minimis is dead. The bill for burying it is only now being itemized — and it is not landing where the headline says it is.
