US Customs is spending billions identifying wrong tariff codes

The importer pays, not the broker.

US Customs has around $3.5bn of new AI and enforcement funding, and won a record $54.4m settlement back in December 2025, which is a lesson for anyone who trades not just with the US, but across any border: incorrect tariff codes are your liability alone, not anyone else’s.

If you ship to the US and leave classification to your broker, US Customs will still see the importer of record, the company with legal liability for every code on every entry, as the importer. Customs and Border Protection (CBP) has just been handed billions of dollars to find any tariff codes that are wrong. It makes the case for using a classification platform, like TTVerified, that ensures you have the correct code, with the audit-trail to back it up, even more compelling.

In June 2026, roughly $3.5bn was directed to CBP for technology, artificial intelligence and enforcement, and the agency has partnered with a private AI screening provider to flag anomalies in classification, valuation and origin before cargo lands. It is already paying off. CBP recovered around $35bn through entry-summary reviews in fiscal 2025, up from $667.6m the year before. And it is not only the obvious offenders getting caught: importers in good standing are receiving surprise duty adjustments and having shipments flagged more often.

December 2025 set the benchmark. Ceratizit USA agreed to pay $54.4m over evaded duties on Chinese tungsten carbide, the largest customs settlement in the history of the False Claims Act. In this case, goods were misclassified under the Harmonized Tariff Schedule to cut the duty rate to zero, the origin was disguised by routing through Taiwan to dodge Section 301 duties, marking duties left unpaid.

The liability does not move

Strip away the US specifics and this is not just a lesson for America, but relevant to everyone. The importer of record is legally responsible for the accuracy of the declaration. “That was the broker’s job” is not a defence any authority accepts, HMRC included, and a new US executive order now requires brokers to vet the importers they act for. Once an authority finds one wrong code, it rarely stops at one shipment, it typically reopens every past entry of that product.

Classification can often be a judgement call, not a simple lookup, and the judgements that catch people out can be small. For example, a cocoa-content threshold that moves a chocolate product into a different duty rate, a prepared food classified by its dominant ingredient, the food-or-supplement borderline where one product sits in three plausible places. Get it wrong once and the same code is copied onto the next order, and the next, until a review turns twelve months of entries into a back-duty letter on one SKU.

Proof, not just a code

There is a timely reason to act now. With the IEEPA tariffs struck down in February 2026, many importers are receiving refunds on duties they should not have paid. Spending some of that money on classification that stands up to scrutiny is a better use of funds than waiting for the review that tests whether your codes were ever right.

None of this is about paying more duty than you owe. It is about being able to prove the duty you owe is correct, with the reasoning, and the audit-trail it was right on the day you filed. That is what audit-ready means, and it’s why many are turning to our TTVerified solution to be sure of every code they ship.
