Importers have until 12:01 a.m. Tuesday to enter goods that were already on the water when the new forced labor tariffs took effect, and the fine print of the 431-page action is testing customs teams like nothing since the first China tariff waves.

WASHINGTON, July 26, 2026
American importers are spending the weekend in a race against a Tuesday morning deadline, as the four-day grace period built into Washington’s sweeping new forced labor tariffs closes at 12:01 a.m. Eastern time on July 28. Goods that were loaded onto a vessel and in transit on their final mode of transport before the duties took effect on Friday escape the new charges only if they are entered for consumption, or withdrawn from warehouse for consumption, before that moment. Anything that misses the window pays.
The stakes of the scramble are substantial. The new Section 301 duties of 10 percent or 12.5 percent, announced Thursday by the Office of the United States Trade Representative and effective at 12:01 a.m. on July 24, apply to imports from 60 economies that together supply 99.4 percent of everything the United States buys from abroad, according to the agency’s own fact sheet. For a single container of goods valued at 500,000 dollars from a country in the higher tier, clearing customs before the deadline rather than after it is worth 62,500 dollars.
Customs brokers describe the period since Thursday’s Federal Register notice as one of the busiest transition weekends in memory, a compressed reprise of the scrambles that accompanied the first Section 301 actions against China in 2018 and 2019. This time the work is harder, because the new action does not impose one rate on one country. It imposes four distinct rate treatments across 60 economies, creates 101 new tariff headings, and spreads its exemptions across fifteen separate lists in a notice that runs 431 pages.
Why the clock is ticking
The in-transit provision is the only transition relief the action offers, and its two conditions are strict. First, the goods must have been loaded and in transit on the final mode of transport before 12:01 a.m. Eastern time on July 24. Cargo sitting at an origin port waiting for a vessel on Thursday night does not qualify. Second, the goods must be entered before 12:01 a.m. on July 28, which converts the usual leisurely rhythm of entry filing into a sprint.
The deadline pairs with a larger changeover that has already reshaped entry processing once this week. The temporary 10 percent global tariff that the administration imposed under Section 122 of the Trade Act of 1974, after the Supreme Court struck down its emergency-powers tariffs in February, expired at midnight Thursday at the end of its statutory 150-day life. The administration timed the new forced labor duties to take effect at the same moment, a senior administration official told reporters, in order “to avoid complexity” for the businesses paying them, as NPR reported.
The result is that entry teams are handling three populations of cargo at once: goods entered before Friday under the old global tariff, goods in the in-transit window that must be documented and filed before Tuesday, and goods loaded after Thursday night that owe the new duties in full. Misfiling any of the three is expensive, and penalties for underpayment apply per entry.
What took effect at midnight Friday
The new duties are the final action in Section 301 investigations USTR opened in March into how 60 economies police forced labor in their supply chains. The agency found that 54 of them failed to impose and effectively enforce a prohibition on importing goods made with forced labor, and that six more, namely Canada, Ecuador, the European Union, Indonesia, Mexico and Pakistan, adopted a prohibition but failed to enforce it effectively.
“The United States has had a forced labour import ban for nearly a century, and rigorously enforces it; it’s well past time for our trading partners to do the same,” Trade Representative Jamieson Greer said, as reported by Euronews.
The political fight over that rationale is loud and will continue: Senator Ron Wyden of Oregon accused the administration at a hearing this week of using “a zombie law” to reconstruct tariffs the Supreme Court threw out, while allied governments from Canberra to Brussels rejected the forced labor findings outright. But for compliance professionals, the argument is beside the point. The duties are in force, they rest on a statute that has survived decades of litigation, and the practical question is not whether to pay but how much, on what, and how to prove it.
Four rate treatments, not two
The headline description of the action, 10 percent for some countries and 12.5 percent for others, understates what entry teams actually face. An analysis by the Global Trade Alert, the Swiss trade policy monitor, breaks the 60 economies into four distinct treatments.
Seventeen economies pay a flat 10 percent additional duty: the United Kingdom, India, Mexico and Canada among them, along with Argentina, Bangladesh, Cambodia, Ecuador, El Salvador, Guatemala, Honduras, Indonesia, Jordan, Malaysia, Pakistan, Sri Lanka and Trinidad and Tobago. These are the economies USTR credits with an import ban, a commitment to one in an Agreement on Reciprocal Trade, or at least a partial regime.
The European Union and Taiwan also land at 10 percent, but their duty applies net of a product’s most-favored-nation tariff. Japan, South Korea and Switzerland get the same net-of-MFN mechanics at 12.5 percent. The remaining 38 economies, including China, Brazil, Vietnam and Russia, pay a flat 12.5 percent, and for China and Brazil the new duty stacks on top of the Section 301 tariffs they already carry.
The net-of-MFN treatment is the technical innovation drawing the most attention, because it means the combined Section 301 and MFN burden on covered products will not exceed the tier rate unless the MFN rate already does. “Those three words, net of MFN, may end up being the biggest story in the entire announcement,” Pete Mento, director of global trade advisory services at Baker Tilly, wrote in a LinkedIn post quoted by Supply Chain Dive. “If it works the way it appears, this isn’t simply another tariff stacked on top of existing duties. It could fundamentally change how the Section 301 duty is calculated for those products.”
For importers of European, Japanese, Korean, Swiss and Taiwanese goods, that calculation is now homework with money attached. Products carrying high MFN rates, such as many apparel and footwear lines, may see effective increases far smaller than the headline tier, while duty-free-MFN products absorb the full charge.
The exemption maze
The action’s exemptions are its most consequential fine print, and they run through one universal list and fourteen targeted ones, all housed in Annex II of the notice, with the legal mechanism set out in a new U.S. Note 52 to the tariff schedule.
Part A, the universal list applying to all 60 economies, covers 2,120 tariff codes, but importers should read it carefully before celebrating: only 863 of those codes are exempt as entered. Another 541 apply only to goods entered for civil aircraft use, 700 only to goods entered for pharmaceutical use, and 16 only to specifically named articles. End-use exemptions require documentation, and claiming them without support is an invitation to a penalty case. The universal list grew by 465 codes between the June proposal and the final action, with nothing removed, so screening decisions made against the proposed list are already out of date.
Thirteen economies received their own additional exemption lists: the United Kingdom, the European Union, Switzerland, Malaysia, Cambodia, Guatemala, El Salvador, Argentina, Bangladesh, Taiwan, Indonesia, Ecuador and Jordan. A further list of 1,737 textile and apparel codes covers Jordan outright and extends to El Salvador and Guatemala for goods entered duty-free under CAFTA-DR.
Note 52 then adds the categorical carve-outs. Goods covered by enumerated Section 232 programs are exempt, as are goods of Canada and Mexico entered duty-free under the USMCA, CAFTA-DR textiles, most Chapter 98 entries, humanitarian donations and informational materials. Energy products and many food categories are spared, as NPR reported. And in a provision with a hard date attached, patented pharmaceutical articles join the Section 232 exemption on July 31.
The USMCA provision may be the single most valuable line in the notice for North American supply chains. Qualifying Canadian and Mexican goods enter free of the forced labor duty entirely, which makes rules-of-origin documentation, long treated as a back-office chore, worth real money on every entry.
Questions the notice does not answer
Several operational questions remain open, and compliance teams should track them as closely as the rules already published.
The first is whether USTR will operate a product exclusion process, as it eventually did for the China tariffs. The notice does not establish one. Companies whose inputs are unavailable from domestic or exempt sources should prepare the factual record now, so that petitions can move quickly if a docket opens.
The second is the timing and design of the tariff-rate quotas the action promises for Bangladesh, Cambodia, Indonesia and Malaysia. The notice directs USTR to establish them when feasible, tied to each economy’s purchases of American cotton and textile inputs, running for an initial three years and allowing a set volume of textiles and apparel to enter duty-free. The mechanism and start date will come in a separate notice, and apparel buyers concentrated in those four countries have millions of dollars riding on the details.
The third is interaction with the other tariff actions of the past week. The notice confirms the new duty stacks on the existing Section 301 tariffs on China and Brazil, but as Supply Chain Dive noted, Thursday’s filing did not spell out how the forced labor duties interact with the separate measures announced against Canada in recent days. Importers exposed to those lanes should expect further guidance and file accordingly.
The diplomacy will not wait for the paperwork
The compliance scramble is unfolding against a diplomatic backdrop that is anything but settled, and entry teams should not assume the rules they are racing to implement will sit still.
Governments across the covered economies spent Friday rejecting the forced labor findings that justify the duties. Australian Trade Minister Don Farrell called the tariffs “unjustified” and demanded their reversal. New Zealand Prime Minister Christopher Luxon said the American investigation “did not provide meaningful evidence” and warned that tariffs “drive up costs and uncertainty for businesses.” The European Union’s foreign policy chief, Kaja Kallas, dismissed the rationale as “not really grounded,” even as the European Commission separately noted the action was consistent with the EU-US Joint Statement and offered “positive momentum” toward further exemptions. Japan called the measure regrettable. China’s foreign ministry warned that “tariff wars and trade wars do not serve any parties’ interests.”
Most of those governments are protesting rather than retaliating, at least for now. The exception is Brazil, which called the action “arbitrary and unjustified” and says retaliatory tariffs are coming, on top of a separate confrontation over the 25 percent duties Washington imposed on Brazilian goods earlier in the week.
For importers, the practical consequence of the diplomacy is rate instability in both directions. The action’s own design invites countries to earn their way into lower tiers by adopting import bans or signing reciprocal trade agreements, which means today’s 12.5 percent supplier country could be a 10 percent country by winter. Retaliation, if it spreads, cuts the other way, threatening the export side of businesses that import and sell abroad through the same corporate family. Sourcing strategies built this weekend should be built to flex.
The price of complexity
Even for companies whose duty bills barely move, the administrative cost of the new landscape is real. The same product can now implicate the ordinary MFN rate, a forced labor duty that may or may not be net of MFN, a preexisting Section 301 duty, Section 232 duties on metal content, and the interplay of 101 new Chapter 99 headings with fifteen exemption lists.
“It has created a much more complex landscape with all of the three-digits going at once and having to figure out: do they add, how does one fit with the other, what are the exceptions?” Kathleen Claussen, a professor at Georgetown Law School who specializes in trade law, told NPR. “It is a far more complex landscape, I think, than it was a year ago.”
The complexity is not evenly distributed. Large importers with automated classification systems and dedicated trade counsel absorbed the China waves of 2018 and 2019 and will absorb this. Middle-market importers, many of whom never faced Section 301 exposure because they source from allies rather than China, are encountering this machinery for the first time, and they are encountering it across every supplier country at once.
Trade advisers are recommending a familiar toolkit, sharpened for the new rules. Screen every classification against Part A and any applicable country list before assuming liability. Document end use rigorously where the civil aircraft and pharmaceutical provisions apply. Perfect USMCA and CAFTA-DR qualification where eligible. Revisit customs valuation, first-sale structures and foreign trade zone strategies, which grow more valuable as duty rates rise. And build the new duties into landed-cost models and customer contracts now, because the rates in force today are explicitly provisional, subject to movement as governments negotiate, retaliate or earn their way into lower tiers.
Winners in the fine print
Every tariff action creates a quiet class of winners, and this one is no exception. British exporters emerged with what their government called “no negative change,” a 10 percent tier assignment cushioned by country-specific carve-outs, including for whisky after the tariff on Scotch was eliminated earlier this year. Jordanian apparel, El Salvadoran and Guatemalan CAFTA-DR textiles, civil aircraft supply chains and pharmaceutical inputs all found shelter in the annexes. Swiss and Japanese products with high MFN rates will feel less than the 12.5 percent headline suggests.
The clearest winners are USMCA-compliant North American supply chains, which now enjoy a duty advantage over nearly every other sourcing option on earth. The paperwork-driven reshoring already underway, in which companies invest in compliance rather than concrete to bring existing production inside the agreement, just received another accelerant.
The losers are equally identifiable: importers from the 38 flat-rate economies, companies with undocumented North American supply chains, and any business that treated Friday’s changeover as a one-for-one swap of a 10 percent tariff for another and planned nothing.
Margins, prices and the ordering calendar
Beyond the filing mechanics, the duties arrive at a sensitive moment in the retail calendar. Late July is peak ordering season for holiday inventory, and merchandising teams are deciding now whether to absorb the new costs, pass them through, or reroute sourcing for spring. The economic studies of earlier Section 301 waves give them little comfort: American importers and consumers bore most of the cost of those duties, with limited evidence that foreign suppliers cut prices to offset them.
The two-tier structure at least gives buyers something to optimize. A 2.5 point spread between the tiers, and the larger gaps created by the net-of-MFN treatments and exemption lists, are wide enough to move sourcing decisions at scale, particularly in categories such as apparel, footwear, furniture and consumer electronics where supplier bases span multiple covered countries. Procurement teams that treated country of origin as a rounding error in 2024 are now modeling it product by product.
For manufacturers, the calculus runs through the input side. The exemptions for Section 232 program goods, energy and many agricultural inputs blunt the worst outcomes, but components and intermediate goods from flat-rate countries carry the full new charge, and those costs compound through multi-stage supply chains. The administration argues the pressure will pull production stateside over time. In the meantime, the costs are due at entry, in cash, beginning with every container that misses Tuesday’s window.
The second cleanup job
The forced labor duties are also landing on a customs system still digesting the last transition. When the Supreme Court invalidated the emergency-powers tariffs in February, the government became liable for refunds to importers who had paid them, an unwinding exercise that has occupied Customs and Border Protection and the trade bar for months. The Section 122 global tariff that followed created its own short-lived compliance regime, and its expiration Thursday night closes out a 150-day program whose final entries and reconciliations will trail on for weeks.
Companies with open claims from the earlier eras should treat them as a separate workstream from the new duties, with separate deadlines and separate records. Brokers warn that the temptation to treat the whole period since February as one continuous tariff muddle is dangerous: three different legal regimes governed entries this year, each with its own liability rules, and audits in future years will examine each on its own terms.
There is one more bookkeeping change worth flagging for smaller traders. With the Section 122 surcharge gone from postal shipments, the duty-free threshold for postal traffic rose to 2,500 dollars on July 24, a meaningful shift for low-value direct-to-consumer flows that had spent months paying the global surcharge.
After Tuesday
When the in-transit window closes Tuesday morning, the new regime settles into place as the operating reality of American import trade. It will not settle for long. USTR is still conducting a separate Section 301 investigation into global manufacturing overcapacity, the administration has floated new sectoral tariffs, and the promised tariff-rate quota notices and possible exclusion procedures will reopen the rulebook within months.
For now, the advice from brokers to their clients is unglamorous: file what can be filed before Tuesday, verify every exemption claim before asserting it, and read the annexes. In a 431-page action, the difference between a 12.5 percent duty and no duty at all is, more often than anyone would like, a single tariff code on a single list.
