The US-China tariff truce is in effect. Reciprocal tariffs on Chinese imports are paused at 10% through November 10, 2026. Fentanyl-related duties were trimmed to 10% in November 2025. On top of existing Section 301 duties, the effective landed rate on Chinese goods is running somewhere between 21% and 35% depending on category, a significant step down from the 145% peak last spring.

The visible reaction from e-commerce brands has been relief. Import volumes rebounded. Air freight surged out of China in mid-2025 as operators restocked. Temu announced it was resuming Chinese factory shipments and increasing US ad spend after the truce was struck. The market read the situation as stabilization.

That reading is wrong, and the operators who've internalized it are about to get hurt for the second time in 14 months.

The truce has a hard expiration date. November 10, 2026 is 194 days from today. Before that, a second cliffhanger: the Section 122 balance-of-payments surcharge, a 15% levy on virtually all imports, has a statutory 150-day cap that puts its expiration at July 24, 2026 unless Congress extends it. That creates two compounding deadline risks in a single quarter. Brands that used the truce to restock without restructuring their sourcing model are positioned exactly as they were in March 2025: dependent on a rate that can move overnight, holding inventory that was priced before the next potential shock.

What the numbers actually show Portless's 2026 Ecommerce Tariffs Benchmark Report surveyed 133 US e-commerce brands. The findings are instructive about how poorly the average operator has adapted. 88% report tariffs have impacted costs or margins. 60% are now carrying more inventory than before tariffs hit. 79% saw margins compress despite raising prices. 62% named unpredictable tariff costs as their number one challenge, not the cost itself, but the inability to plan around it.

That last number is the operative one. These brands are holding more inventory, charging more per unit, and still losing margin. The problem is structural, and stocking more product before the next potential rate change doesn't fix a structural problem. It amplifies the exposure.

The brands managing best share one characteristic in common, according to the same report: they changed where in the supply chain they pay tariffs, not just what they charge customers.

The Vietnam trap that's costing operators real money The standard playbook that spread across the industry in 2025 was "China Plus One": shift sourcing to Vietnam, India, or Mexico to reduce China exposure. This advice was broadly correct at the principle level and broadly executed incorrectly at the operational level.

Vietnam's US reciprocal tariff under current policy sits at 46%. China's effective rate is approximately 31%. A brand that moved production to Vietnam to reduce US tariff exposure may have increased it, depending on production costs, freight differentials, and which duties apply.

Vietnam's genuine tariff advantage is in non-US corridors. As a CPTPP signatory, Vietnamese-origin goods enter Japan, Australia, Canada, and the UK at zero or near-zero duty. Under the EU-Vietnam Free Trade Agreement, EU access is similarly favorable. The supply chain diversification logic is correct, but the destination market mapping has to match the sourcing country, not just the origin country headline.

The brands building real structural advantages right now are running multi-corridor sourcing: China for US sales where the effective rate is manageable and production scale is unmatched, Vietnam for CPTPP-market fulfillment, India for EU and UK, and Mexico for US sales requiring USMCA qualification. This is not a strategic observation. It's a landed-cost calculation that a spreadsheet can verify in an afternoon.

What Amazon and Temu proved about fulfillment model The most clarifying data point from the 2025 tariff crisis came from the competitive dynamics between Amazon and the Chinese discount platforms. When de minimis ended for Chinese imports on May 2, 2025, Temu's US daily active users fell 52% between March and May, according to Sensor Tower data reported by CNBC. Shein's DAUs dropped 25% over the same period.

Amazon's Q2 2025 sales grew 13%, accelerating from 10% in Q1. The company's unit sales grew 12%.

The structural difference was fulfillment model. Amazon's marketplace was already running bulk-import, US-warehouse fulfillment. Temu and Shein had built their entire customer proposition on de minimis small-parcel direct shipping from China. When that model died, their landed economics broke. They've since opened US warehouses, but the customer trust loss was immediate and measurable.

In the weeks after de minimis ended for all countries on August 29, 2025, consumers who had been shopping on Chinese platforms redirected spending toward Old Navy, Nordstrom Rack, and Ulta Beauty, according to Consumer Edge research. The competitive shift didn't require the US operators to do anything novel. It required the Chinese-model platforms to face costs the domestic-fulfillment operators had already absorbed.

The lesson for DTC brands is not that Amazon wins. It's that the fulfillment model is a tariff management tool. Brands importing bulk inventory into US 3PLs and fulfilling domestically are paying tariffs once, at import, at a predictable time. Brands using cross-border drop models are paying tariffs per package, at customs clearance, at whatever rate applies the day the package arrives.

The hidden cost in your current inventory position De minimis ended for all US imports on August 29, 2025. The Universal Postal Union reported that the number of sub-$800 parcels entering the US fell 54% in the four months after the exemption ended. That collapse reflects 1.36 billion annual packages that previously cleared customs duty-free. Every single one of those transactions is now a duty event.

For dropshippers and cross-border operators, the math is straightforward and brutal. A $15 product from China with a 35% effective duty rate carries $5.25 in duties at the product level, plus brokerage, bond, merchandise processing fees, and harbor maintenance fees. Fixed customs costs on a small package can exceed the product value. The unit economics of low-cost cross-border dropshipping are broken in a way that doesn't get fixed by negotiating a better product price.

Tapestry, which owns Coach and Kate Spade and uses cross-border fulfillment for a portion of its direct-to-consumer volume, disclosed in August 2025 that the earlier-than-expected end of de minimis represented "a meaningful factor" in what it projected as a $160 million profit headwind from tariffs, 230 basis points of margin. That's a business with the resources to absorb that cost. Smaller brands with thinner margins have no equivalent buffer.

Why the next escalation will be harder to manage than the last In spring 2025, the tariff shock caught most brands mid-cycle. They hadn't modeled the rate changes, hadn't mapped their SKU exposure at the product level, and had supply chains built around assumptions that no longer held. The 90-day truce in May 2025 gave them a partial reprieve. The November 2025 truce extension gave them more runway.

The November 10, 2026 expiration will not carry the same excuse of surprise. Every operator who is active in this industry knows the date. When the truce expires, or when it gets replaced with something worse, or with a renegotiated rate structure that applies differently by category, the brands that prepared during this window will have already moved product, locked contracts, re-mapped their landed costs, and positioned inventory in structures that delay or reduce duty payment. The brands that treated the truce as a solution rather than a window will be running the same emergency triage they ran in April 2025, but with less runway and creditors who remember last time.

The Truce Window Framework: What to Do in the Next 194 Days Phase 1: The SKU-level landed cost audit (this week, 3-5 days)

Before any sourcing decision, pricing change, or inventory commitment, you need a landed cost model that is current, product-specific, and scenario-tested. Most brands have a blended COGS number that bakes in an average duty rate across their catalog. That number is wrong for most individual SKUs and useless for making decisions about specific products.

The correct model for each SKU: product cost + international freight + applicable duty rate (base HTS rate + Section 301 + remaining Section 122 surcharge where applicable) + brokerage fee + bond cost + merchandise processing fee + harbor maintenance fee + domestic freight to 3PL. Run this calculation at three tariff rates: current effective rate, current rate plus 15% (if Section 122 gets extended), and current rate plus an additional 10% (representing a partial escalation if the November truce fails to renew cleanly).

If you have 200 SKUs, this is a multi-day project. If you have 500+, it requires a customs broker and a spreadsheet system, not a guess. The brands that went bankrupt in 2025 while looking profitable on paper share one characteristic: they were using blended margin assumptions that didn't reflect what they were actually paying per unit at the border.

This audit produces three outputs. First, your current true gross margin by SKU, not by category. Second, your exposure ranking, which products become margin-negative if rates increase by 15%. Third, your sourcing priority list, which SKUs are candidates for alternative sourcing vs. which ones are defensible at current rates.

Phase 2: The dual cliffhanger positioning strategy (next 30 days)

Two rate changes are coming within a 16-week window: the potential Section 122 expiration on July 24, and the China truce expiration on November 10. They create opposite incentives if you read them in isolation, which is why most operators are paralyzed or making the wrong move.

If Section 122 expires as scheduled on July 24, duty rates drop by 15% on a wide range of imports. Goods stored in a bonded warehouse and withdrawn in August would pay zero Section 122 duty. That's a real benefit for brands that can afford to hold inventory in bonded storage and time the withdrawal.

If Section 122 gets extended, the more likely scenario, the bonded warehouse strategy still works as a cash flow tool, just without the rate-change benefit.

The play that covers both scenarios: import goods before July 24 and store them in bonded warehouse or FTZ. If the surcharge expires, withdraw post-July 24 at the lower rate. If it gets extended, you've delayed the duty payment until withdrawal, preserving cash flow. The FTZ offers an additional benefit: goods can be manufactured or assembled inside the zone, and the finished product may carry a lower duty rate than the inputs. For brands with any US-based production or kitting operations, this is worth a conversation with a licensed customs broker this month.

For the November 10 China truce expiration, the inventory position to build toward is 90 to 120 days of key SKU supply inside US warehouses by late August. This mirrors what every experienced supply chain operator learned from the May 2025 truce: the window for pre-positioning closes fast when rate changes get announced, air freight rates spike immediately, and ocean lead times mean goods ordered in October don't arrive until January.

Phase 3: Multi-corridor sourcing re-architecture (60-90 day horizon)

The reductive version of supply chain diversification, which dominated industry conversation in 2025, was "move production out of China." The more accurate framing is: match your sourcing country to your destination market based on the FTA coverage that applies, and then verify the landed cost math in that specific corridor.

Here is the corridor map that works at the product category level as of today:

For US-market sales requiring USMCA qualification, Mexico sourcing at zero duty is the cleanest play for brands that can establish manufacturing there. The complexity is real, Mexico requires genuine value-added production, not just final assembly, to qualify, but the duty benefit is permanent and not subject to annual renegotiation.

For EU and UK sales, Vietnam's EU-Vietnam FTA and UK trade arrangements give zero or near-zero duty on most goods. India's growing production capacity in textiles, home goods, and jewelry hits at favorable EU GSP rates. For brands with meaningful European revenue, running EU-bound fulfillment through Vietnamese or Indian production while keeping US-bound inventory in China is not a theoretical optimization, it's a 10-to-20 point landed cost differential.

For US-bound goods from China, the current effective rate in the 21-35% range is the baseline to work from. The question is which products can absorb that cost at your price points and which ones cannot. The ones that cannot are your Phase 1 audit priority for alternative sourcing.

A critical compliance detail that most brands miss when executing sourcing shifts: product certifications in new manufacturing markets must be completed before the first shipment. BIS certification in India takes 3-6 months. Vietnamese MOIT type approval takes 1-3 months. BSTI in Bangladesh takes 1-2 months. A new supplier producing conforming goods that gets held at the border because the importer has no product certification is not a sourcing success. It's a new problem in a new location. Build certification timelines into your supplier transition as a hard constraint, not an afterthought.

What's Actually Working: Oxford Industries cuts China sourcing from 40% to 15% in 12 months Oxford Industries, the owner of Tommy Bahama, Lilly Pulitzer, and Johnny Was, is one of the clearest documented examples of a fashion company executing a genuine supply chain restructure under tariff pressure, reported directly through SEC filings and earnings calls.

In fiscal year 2024, approximately 40% and 25% of Oxford's finished goods were sourced from China and Vietnam respectively. When tariffs hit in early 2025, the company ran the same exposure math that every apparel operator should be running right now and didn't like what it saw. Based on current tariff policies and historical sourcing patterns, Oxford estimated that, absent proactive mitigation, it would incur approximately $80 million in incremental tariffs during fiscal 2025.

The company moved immediately rather than waiting for the environment to stabilize. It estimated it mitigated roughly half of that fiscal 2025 exposure through actions already completed, including accelerating product receipts and shifting sourcing. The company shifted production toward Cambodia, India, Indonesia, Peru, Sri Lanka, Thailand, and Turkey, specifically avoiding long-term supplier contracts to preserve flexibility as the policy environment evolved.

The pace of the reduction is the most instructive detail. China sourcing went from 40% early in fiscal 2025, to slightly under 30% by end of fiscal 2025, to an annualized run rate of approximately 15% entering fiscal 2026. The company's stated goal is to be substantially out of China by late 2026.

The restructure did not eliminate the tariff cost. The full-year fiscal 2025 gross margin decline was driven primarily by approximately $30 million in higher cost of goods, or 200 basis points, from additional tariffs enacted during the year. Oxford also paid approximately $40 million in tariffs imposed under IEEPA that were later struck down by the Supreme Court, and those payments are not included in fiscal 2025 results or fiscal 2026 guidance pending resolution of timing and collectability.

But the sourcing restructure protected the ceiling. CEO Tom Chubb stated that the strategic actions taken to strengthen the supply chain and diversify sourcing allowed the company to protect strong gross margins through the disruption, and that absent tariffs, gross margin would have increased year over year.

For fiscal 2026, Oxford is projecting approximately $50 million in IEEPA-related tariff impact, a roughly 150 basis point gross margin headwind, with a Q1 front-load of approximately $12 million. That's a significant ongoing cost. It's also roughly 38% lower than the $80 million exposure they were staring at in spring 2025 before the restructure. The delta is the value of the sourcing work they did while everyone else was debating whether the tariffs were permanent.

The Oxford case is not a playbook for a $5 million DTC brand to follow point by point. The brand has dedicated sourcing teams, long supplier relationships across a dozen countries, and the balance sheet to absorb the transition costs. What it demonstrates is the sequencing: run the full exposure math first, move before the environment forces you to, and treat the flexibility of not being locked into long-term supplier contracts as a strategic asset rather than a negotiating disadvantage. Oxford had that flexibility by design. Most smaller brands have it by default, because they haven't formalized their supplier relationships either way. That's an advantage if you use the window.
