Early last year, we wrote about how retail brands could use technology to adapt to tariffs. At the time, the conversation was about building foundational resilience: model a few duty scenarios, diversify away from high-tariff regions, understand your landed cost before it moved on you. That advice still holds, but if you run planning for a brand or retailer, you already know the ground has shifted underneath it.
The question in early 2025 was where do we source, and what happens if duties show 25%. The question in 2026 is different. You've diversified and built the scenarios. The bottleneck now isn't knowing what to do. It's how fast you can actually do it.
The Cost Moved. Prices Didn't. Margin Took the Hit.
Start with the number that reframes everything. Industry trade data compiled by the University of Delaware's Fashion & Apparel Studies group shows the effective average tariff rate on U.S. apparel imports climbed from 14.7% in January 2025 to 35.1% by December 2025. That's more than a 20 point jump at the border in a single year.
Almost none of it reached the shelf. Apparel retail prices rose just 0.3% year over year over the same stretch, because brands absorbed the increase rather than test a cautious consumer. So the question of who pays the tariff already has an answer for 2025: the retailer did, out of margin.
You can see it in the executive data. KPMG's Retail Executive Survey found half of general merchandise retailers reported a gross margin drop of one to five points tied directly to tariffs, the steepest compression of any sector surveyed.
In the same survey, 57% reported softer overall sales volume, and more than a third saw international sales fall 16 to 25% as retaliation and trade friction bit into export demand.
That absorption strategy is running out of room. The State of Fashion 2026 report found 71% of fashion and retail executives now plan price increases, up from 52% in 2024, and 45% are planning increases above 5%.
The cushion that held prices flat in 2025 is being spent, which means pricing and cost decisions can no longer be made in separate rooms.
Volatility Stopped Being an Event and Became the Baseline
The scenario models most teams built last year assumed a shock you could plan around. One duty change, absorb it, move on. A rate that nearly triples in twelve months is different. Quarterly scenario planning couldn't keep pace with a number moving faster than the planning cycle refreshed.
The people living this agree. In SPS Commerce's 2026 trade research, 72% of trade professionals named U.S. tariff volatility as the single most impactful regulatory pressure they face. Not a one-time disruption, but permanent operating condition.
So the differentiator changed. It's no longer the quality of your scenario deck, but the time between spotting a tariff-driven cost shift and having it reflected in your purchase orders, open-to-buy, and landed-cost rollups. That’s where the margin starts to leak.
De-Risking Sourcing Turned Into a Full Supply Base Rewrite
Planners learned to both trim exposure to high-tariff regions, as well as building around them. U.S. soft goods imports from China fell 53.3% in dollar value and 43.1% in units year over year, and China's share of U.S. soft-goods imports hit a multi-decade low of 11.3% by late 2025, down from 19.8% a year earlier.
That volume went somewhere, mostly into trade-agreed territory. CAFTA-DR duty-free utilization rose to 76.1%, and USMCA duty-free claims for qualifying goods rose to 88.3%.
Moving that much sourcing that fast only works if you can shift active purchase orders across a vendor network without eating a lead-time penalty every time a rate changes. Execution becomes even more challenging.
Front-Loading Worked Once, Then the Ledge Came
When duties loomed, the common move was to ship early and beat the deadline, which was reasonable. It was also expensive in ways that didn’t rear its head until later. A survey from STG Logistics found 52.3% of importers avoided duties by shipping ahead, but 43.7% took on severe working capital strain doing it and 42.3% saw holding costs spike.
That's why 2026 planning leans on flexibility instead of buffers: foreign trade zones, bonded storage, shorter and more variable carrier contracts. The goal to avoid carrying the risk on your own balance sheet vs. pre-buying your way out of a tariff.
Tariff Engineering is Now a Planning Input
Because duty rates vary by material, product teams started redesigning to land in lower brackets. Man-made synthetic fibers, which carry MFN rates in the 16 to 32% range, dropped from 57.9 to 56.6% of imports, while lower-duty cotton rose from 38.5 to 39.9%.
Small shifts on paper, but they represent merchants deliberately altering fiber content to cut border tax. When product composition becomes a cost lever, design and planning have to share the same landed-cost view, or you're optimizing one without seeing the other.
What this means for how you plan
The through-line is simple: every lever that mattered last year still matters. What changed is the cadence speed.
Scenario modeling became continuous replanning: re-forecasting landed cost and open-to-buy weekly instead of two or three static views per season. Sourcing diversification became execution speed. Inventory buffers became capital efficiency. Cost absorption became integrated margin management, adjusting price and markdown in step with the cost shifts underneath them.
None of that works if your cost, your buy, and your pricing live in separate files reconciled once a month. When the tariff rate jumps 20 points and prices only move a fraction, the difference lands in margin, and the retailers protecting theirs are the ones who can replan fast enough to keep up. Nobody has the better forecast of where tariffs are headed. The edge is absorbing the change faster than the competition.
If your planning process still runs on a quarterly rhythm, that's worth dealing with first. It's the same case we made for modernizing last year, only now the cost of a slow replanning cycle shows up plainly on the P&L.
