What the data shows
The National Retail Federation's Global Port Tracker, produced with Hackett Associates, reports that U.S. container ports handled 2.23 million twenty-foot equivalent units in June 2026, up 13.2 percent from a year earlier and down only slightly from May's pace. First-half 2026 volume reached 12.7 million TEU, up 1.1 percent versus the first half of 2025, a modest headline number that masks a much sharper acceleration in the months immediately before the tariff deadline. May 2026 was the peak month at 2.24 million TEU. NRF now projects full-year 2026 volume at approximately 25.5 million TEU, essentially flat against 2025's 25.4 million, which means the surge did not represent new demand so much as retailers moving planned import volume earlier on the calendar to beat the tariff deadline.
Jonathan Gold, NRF's vice president for supply chain and customs policy, said retailers had an early peak season this year as they brought in merchandise ahead of tariff changes in late July and responded to other supply chain uncertainty, including ongoing disruption tied to the conflict in Iran. His conclusion, delivered with the confidence of someone who has watched this pattern play out before, is that despite the tariff transition, retailers will be well stocked for the coming holiday season, a reassuring message for an industry that spent much of the first half of the year bracing for shortages.
The tariff mechanics behind the rush
A temporary 10 percent Section 122 global tariff, in effect since February, expired July 23. New Section 301 tariffs of 10 to 12.5 percent tied to forced labor concerns took effect July 24, covering 60 economies and an estimated 99 percent of all U.S. imports. That is an unusually broad tariff structure, and it gave retailers a defined, narrow window between the old and new tariff regimes to pull inventory in at the lower, expiring rate before the new one applied.
This is the second consecutive tariff transition in 2026 that has triggered a visible frontloading pattern in the port data, following a similar surge earlier in the year around the Section 122 tariff's introduction. Retailers that have now been through two of these cycles this year are building institutional muscle memory for how to execute them, and that experience is becoming a durable operational advantage over competitors still treating each tariff announcement as a one-off crisis.
Why this is a systems problem, not a procurement problem
Successfully frontloading inventory ahead of a tariff deadline requires knowing, with reasonable precision, which SKUs are exposed to the new tariff, what the cost delta is per unit, and whether pulling orders forward creates warehouse capacity or cash flow problems elsewhere in the network. That is not a decision a merchandising team can make from spreadsheets when the tariff list covers 99 percent of imports across 60 countries and touches nearly every category a general merchandise retailer carries. It requires trade compliance software integrated with the ERP and demand forecasting systems, capable of flagging exposure and modeling scenarios within days of a tariff announcement rather than the weeks a manual cross-functional review would otherwise take.
Retailers without that integration were making frontloading decisions based on incomplete visibility, either overordering categories that turned out not to be exposed or underordering categories that were, tying up working capital in the wrong places at exactly the wrong moment. The retailers now telling NRF they are well stocked for the holidays are implicitly the ones whose systems could answer the tariff exposure question fast enough to act inside the narrow window between the old and new tariff rates, while slower-moving competitors are still reconciling purchase orders against a tariff schedule that changed weeks ago.
The forecast has a hidden warning in it
The flat full-year import projection, 25.5 million TEU against 25.4 million the year before, is worth reading carefully. It means retailers largely borrowed against future import volume rather than genuinely increasing orders, which implies August through December volumes will run below normal seasonal patterns since the holiday inventory already arrived early. NRF's own projections show August down 4.2 percent year over year and July down 7.6 percent, both consistent with that pull-forward effect.
For finance and operations leaders, this means the holiday inventory position looks strong today but the supply chain has less slack than usual heading into the actual peak selling season, since the normal cushion of late-arriving goods will not be there if demand runs hotter than forecast in any single category. Systems that can reallocate inventory across channels and regions in real time become more valuable in exactly this kind of scenario, where the safety margin from fresh imports is thinner than a typical year.
What CIOs should take from this cycle
Tariff volatility looks set to remain a permanent planning variable well past this particular transition, given that it has already happened twice in 2026 alone with little sign of the underlying trade policy stabilizing. Retail technology leaders should treat trade compliance and tariff scenario modeling as permanent, always-on infrastructure, budgeted and staffed year-round, rather than a project stood up reactively each time a new tariff deadline gets announced on short notice by Washington.
The practical investment is integration: connecting customs and trade compliance data, ERP purchase order systems, and demand forecasting into a pipeline that can answer a tariff exposure question within days, not through a manual cross-functional fire drill. Retailers that build this once will handle the next tariff cycle, and there will be a next one, with the same operational calm NRF is describing this time. Retailers that do not will keep relying on frontloading scrambles that work only when the timing happens to line up.
