You’ve been overlooking the quiet boom in China’s warehouse clubs—until now.
Data from Kantar Worldpanel shows that in 2025 China’s membership‑based warehouse stores posted more than 20% year‑on‑year sales growth. By contrast, many large‑format supermarkets saw foot traffic shrink as consumers gravitated toward curated, cost‑effective assortments. The model’s appeal is simple: a small, tightly‑managed SKU count (usually a few thousand versus tens of thousands) reduces decision fatigue and signals disciplined quality control.
Chinese shoppers are not merely “trading down.” They are trading differently—seeking a blend of quality, price transparency, and the psychological comfort of buying “smart” rather than “cheap.” The membership fee itself creates a commitment bias, encouraging members to maximize the perceived value of each visit.
Both Sam’s Club and Alibaba’s Hema have accelerated the rollout of in‑house brands. Leveraging massive supply‑chain scale and data analytics, these private labels can match or exceed the quality of imported products at lower price points. For multinational staples firms, the implication is clear: tighter price competition and a shrinking premium‑price cushion.
When a retailer can substitute a $2.50 box of imported cereal with a $2.00 private‑label equivalent that delivers comparable taste and nutrition, the margin on the shelf narrows. Over time, this erosion can translate into a multi‑percentage‑point decline in gross margin for global brands that rely heavily on the Chinese market for growth.
Costco’s limited but highly publicized openings still generate long queues, reinforcing the aspirational cachet of the foreign brand. Sam’s Club has taken a more aggressive expansion route, opening stores in tier‑1 and tier‑2 cities while building a robust delivery ecosystem.
Domestic rivals such as Pangdonglai and the Hema platform are not merely imitators; they embed local preferences into every facet of the offering— from meat cuts tailored to Chinese cooking methods to digital payment integrations that sync with local super‑apps. This hybrid approach gives them a cost advantage and a deeper data moat.
When Costco and Sam’s Club first entered the United States in the 1990s, analysts predicted a niche market that would never challenge traditional grocers. Within a decade, warehouse clubs accounted for roughly 10% of total grocery sales and forced legacy retailers to launch their own “value” formats. The lesson for China is the same: a seemingly niche model can become a mainstream driver of consumer spend.
In the U.S., the rise of private labels within warehouse clubs also pressured multinational CPGs, prompting many to innovate with premium sub‑brands or to double‑down on niche, high‑margin categories. Chinese multinationals may need to repeat this strategic pivot.
Bull case: The membership model is still early in its lifecycle in China. Continued urbanization, rising middle‑class incomes, and the digital integration of e‑commerce with brick‑and‑mortar will expand the addressable market. Companies that successfully blend global brand equity with localized private‑label offerings could capture a larger share of a higher‑spending consumer base.
Bear case: If private‑label acceptance deepens, multinational staples may face sustained margin compression in China, their once‑reliable growth engine. A prolonged property‑sector slowdown could further dampen discretionary spend, making the “smart‑shopping” mindset permanent rather than temporary.
Strategically, investors should monitor three leading indicators: (1) membership growth rates for Costco, Sam’s Club and domestic clubs; (2) the share of private‑label SKUs within the top‑100 best‑selling categories; and (3) gross‑margin trends for the Chinese segment of P&G, Unilever and Nestlé. Positioning that balances exposure to the retail‑format winners while hedging against margin erosion in global CPGs may offer the best risk‑adjusted return.
