There is a tariff on your goods now that has nothing to do with your goods.
It does not depend on what you import, where you make it, who makes it, or how well you audit them. Your factory can be immaculate. Your supply chain can be documented to the third tier. The tariff applies anyway, because it was not imposed on you or on your supplier. It was imposed on your supplier's government.
Sixty economies are covered. Together they account for more than ninety-nine per cent of what the United States imported in 2024.
What Was Decided
In March 2026 the Office of the United States Trade Representative opened Section 301 investigations into sixty economies (ustr.gov), asking whether their failure to impose and effectively enforce a prohibition on importing goods produced with forced labour was unreasonable and burdened U.S. commerce.
In June it published findings and proposed action (ustr.gov). On July 28 the Federal Register carried the notice of actions taken (federalregister.gov). The additional duties applied to goods entered for consumption on or after 12:01 a.m. eastern time on July 24, 2026, with a grace provision for goods already in transit before July 28.
Two Rates, and a Cap
The structure is simpler than most Section 301 actions, and it is worth knowing which side of it your suppliers sit on.
Ten per cent applies to Argentina, Bangladesh, Cambodia, Canada, Ecuador, El Salvador, Guatemala, Honduras, India, Indonesia, Jordan, Malaysia, Mexico, Pakistan, Sri Lanka, Trinidad and Tobago and the United Kingdom.
Twelve and a half per cent applies to the remaining thirty-two economies, a list that includes China, Russia, Saudi Arabia and Vietnam.
Then a mechanism that is easy to miss. For the European Union and Taiwan the ten per cent is applied net of the most-favoured-nation duty and capped so that the total does not exceed ten per cent. Japan, South Korea and Switzerland get the same treatment at twelve and a half. Where a product already carries a normal duty, that arithmetic matters, and it is the sort of thing that is either handled correctly by your broker or quietly is not.
Why This One Is Different
Most trade measures attach to something you can inspect. Antidumping duties attach to a product and a producer. Section 232 attaches to a category. The Uyghur Forced Labor Prevention Act attaches to goods with a specific supply-chain link, and the response is to document the chain and prove the link is absent.
This attaches to a legislature.
The finding is not that your supplier used forced labour. It is that the country your supplier sits in has not adopted and effectively enforced a law banning the import of goods made with forced labour. Notably, USTR's position was that none of the sixty economies investigated had both adopted and effectively enforced such a prohibition.
The practical consequence is uncomfortable: there is no diligence you can perform on your own supply chain that removes this duty. Auditing your factory does not help. Mapping your tiers does not help. Those things remain worth doing, for reasons that have not changed and that this measure does not touch. They simply will not move this number.
What Actually Can Move It
Three things, in descending order of usefulness.
Check the exemptions, because they are extensive and specific. The notice carries universal exemptions covering informational materials, donations, accompanied baggage, articles already subject to Section 232 duties, and a further four hundred and seventy-one products identified as raw materials, goods not available domestically, or goods whose tariffing would be disruptive. If any of your classifications sit in that list, the answer to this whole article is that it does not apply to you. That is a specific, checkable question for your customs broker, and it is the first one to ask.
Then check the economy-specific annexes. Beyond the universal list, individual economies have their own product carve-outs, described as designed to encourage commitments on prohibiting forced labour. In other words they are bargaining chips, and what is exempt for one country is not exempt for another.
Then, when you are choosing where to produce, note that the gap between the two tiers is two and a half points. That is not enormous, but it is real and it is permanent in a way a freight rate is not. An importer weighing Vietnam against India, or China against Mexico, is now weighing twelve and a half against ten before anything else is counted.
One detail suggests this is not static. Tariff-rate quotas for Bangladesh, Cambodia, Indonesia and Malaysia carry an initial duration of three years, which implies a mechanism that can be revisited rather than a permanent settlement.
Where That Leaves Sourcing
The uncomfortable conclusion is that a country's legislative posture is now a line item in your landed cost.
That is a genuinely new thing to have to think about. Nobody chose a factory in 2019 on the basis of whether that country had enacted an import prohibition on forced-labour goods. It was not a commercial variable. It is one now, and unlike quality or price or lead time it is entirely outside the influence of both you and your supplier.
What that argues for is not panic but arithmetic. Find out whether your products are on the exemption list, because a large number of importers will discover this does not touch them at all. Find out which tier each of your sourcing countries falls into, and carry it into the next comparison rather than the next crisis. And keep the reasoning somewhere, because with sixty economies and two annexes of exemptions, the question of why a particular duty applied to a particular entry is one somebody will ask you later.
This is general commentary, not legal or customs advice. The annexes are long, the exemptions are specific to classification, and the treatment of net-of-MFN caps is technical. Confirm your own exposure with a licensed customs broker or trade counsel, and read the Federal Register notice rather than any summary of it, this one included.
So — do you know which of the two tiers each of your sourcing countries is in, and whether any of your classifications are on the exemption list? And what are you using today to hold that against each product, so the answer survives the next time the rates change?
