Shein’s IPO Filing Confirms What Amazon Already Fixed: Where the Goods Actually Ship From

Shein’s Hong Kong IPO prospectus, filed in late July 2026, settles a question analysts had been asking for two years: more than 90% of its 2025 net revenue still came from goods stored in central warehouses in China before shipping. That number lands despite Shein opening a U.S. marketplace in May 2023 explicitly framed as a localization strategy — and it explains, more than any single tariff, why the company just posted its first quarterly loss.

For Amazon sellers, the number is less interesting as a Shein story than as a case study in a decision every China-sourcing seller eventually has to make: whether goods ship from China order-by-order, or get positioned domestically ahead of demand.

The Marketplace Was Supposed to Be the Hedge

When Shein opened its U.S. third-party marketplace, its head of strategy described the goal as recruiting sellers who could reach Shein’s customer base in local geographies. Within months, Shein had added tens of thousands of sellers — but nearly all of them were based in China rather than the U.S. sellers the strategy was supposed to attract. The marketplace did build real scale, reaching an estimated $6 billion in U.S. GMV, about 24% of Shein’s U.S. total. But GMV share isn’t the same as where the goods physically originate, and the origin barely moved: adding a marketplace layer didn’t diversify the underlying exposure it was built to reduce.

Every Platform Answered the Same Question — Differently

Every major cross-border platform has had to confront where its goods actually ship from, and the answers have diverged permanently:

• Temu rebuilt its supply chain around local fulfillment, moving from essentially zero U.S. local sales at the start of 2024 to roughly 20% by mid-year and higher since, fast enough that some orders now arrive within two days.
• TikTok Shop, despite a content-first model Shein never had, invested in Fulfilled by TikTok specifically to bring delivery under its own control rather than leaving it dependent on direct-from-China shipping.
• Shein changed its seller roster and its public messaging, but the underlying goods kept shipping from the same Chinese warehouses the whole time.

Amazon solved this earliest and most thoroughly, years before the current tariff pressure existed. Its active seller base passed 50% China-registered in September 2025, but the overwhelming majority of those sellers use FBA, so the goods themselves sit in Amazon’s own FBA supply chain and ship domestically — country of registration became almost invisible to the shopper checking out, because Amazon domesticated the fulfillment step regardless of where the seller itself is based.

The Financial Toll of Staying Put

With no domestic buffer built, Shein had nothing to absorb the shock when the U.S. removed the de minimis exemption. First-quarter 2026 U.S. revenue fell 14.3% year-over-year to $2.04 billion, and operating margin compressed from 3.9% to 2.9% — enough to tip the quarter into a net loss even though order volumes held up. Demand for the product was intact; the economics of shipping it the way Shein always had were not.

The deceleration was already visible across all of 2025 before the quarterly loss hit — this wasn’t a single bad quarter so much as a business whose growth had been slowing as the cost of reaching its two largest markets kept rising.

Europe Is Now Running the Same Play

The U.S. and Europe together account for roughly two-thirds of Shein’s revenue, and Europe introduced its own version of the same pressure on July 1, 2026: a €3 fee applied per customs item classification rather than per parcel. Because it’s charged per item classification rather than per shipment, a single multi-item order shipped direct from China can trigger the fee several times over in one parcel — a more targeted strike at the central-warehouse model than the U.S. tariff was, and one that falls specifically on platforms that never moved fulfillment out of China.

What This Means for Amazon Sellers

Two distinct takeaways follow from this, and they point in different directions:

• There’s a competitive opening in apparel and fast fashion specifically. Reporting from Consumer Edge and Similarweb has shown Shein and Temu spending both down double digits following the tariff changes, with no meaningful rebound since — and Amazon has been positioned as a direct beneficiary as US shoppers shift fast-fashion spend away from China-direct platforms. Amazon apparel sellers competing against Shein-style pricing have a real window to capture share that isn’t purely about matching price anymore.
• There’s a cautionary parallel for any seller still shipping direct-from-China rather than positioning inventory domestically. Shein’s core lesson isn’t really about fast fashion — it’s that a business model built entirely around one country of origin has no buffer when the rules governing that route change, and the rules have now changed twice on two continents in under two years.

For sellers still weighing how much of their catalog to keep on direct-from-China fulfillment versus FBA or another domestic option, this is a concrete argument to diversify where their inventory ships from before a policy change forces the decision at a worse moment than the one you’d pick yourself.

The Bottom Line

Shein spent three years telling investors and regulators that its marketplace was diversifying its supply chain. Its own IPO filing says otherwise: more than 90% of 2025 revenue still originated from Chinese central warehouses. Amazon didn’t have to make this argument to investors, because FBA had already made the origin question close to irrelevant to the shopper years before tariffs made it urgent for everyone else. That’s not a reason for complacency — it’s a reminder that the sellers who solve the origin question before it’s forced on them end up with options the ones who don’t no longer have.
