The global apparel industry has spent the past few years pursuing a straightforward strategy: reduce dependence on China by moving production to Vietnam, Bangladesh, India and other lower-cost manufacturing destinations. For conventional apparel, that strategy can work. But Shein’s retreat from a major logistics project in Vietnam shows why the same formula becomes far more difficult when the business model depends on ultra-fast, micro-batch production.

Shein has sharply reduced its planned warehouse footprint near Ho Chi Minh City, cutting it from about 15 hectares to roughly six hectares, while also reducing its workforce. The reversal is significant because the Vietnamese facility was intended to strengthen the company’s ability to serve overseas consumers while reducing exposure to trade restrictions affecting China. The lesson extends beyond Shein. Nearshoring can diversify supply chains, but it does not automatically reproduce the dense industrial ecosystem that makes China exceptionally competitive in fast, flexible and small-volume manufacturing.

The tariff advantage fades

Shein’s original Vietnam strategy was closely linked to US trade policy. The company encouraged parts of its Chinese supplier network to establish production capacity in Vietnam as Washington increased scrutiny of Chinese imports.

The attraction was straightforward. Low-value shipments had always benefited from the US Section 321 de minimis exemption, allowing packages valued below $800 to enter without normal customs duties. That gave cross-border platforms such as Shein a powerful economic advantage because products could be shipped directly to consumers rather than passing through conventional distribution channels. That advantage has now largely disappeared.

 China and Hong Kong and subsequently extended the policy globally. Once the exemption ceased to give a meaningful origin advantage, Vietnam lost an important reason for becoming a distribution base for a Chinese-led cross-border model. Vietnam can still retain a tariff advantage over Chinese-origin merchandise in some product categories. But the calculation for Shein is not simply the headline tariff. Freight, handling, inventory, production minimums, labour productivity and speed all matter. For a business selling inexpensive garments at extremely high volumes, even small increases in these costs can erase a nominal tariff saving.

Speed is the real attraction

The bigger obstacle is operational rather than regulatory. Shein's model is built around testing demand before committing significant production. Suppliers can initially produce tiny quantities, sometimes only 100–200 pieces. Customer clicks, purchases and engagement then determine whether a style should be scaled. This system requires factories that can accept small orders, change production schedules rapidly and replenish successful products almost immediately. That is where Guangdong has an advantage that cannot easily be relocated.

The Panyu and wider Guangdong manufacturing system contains thousands of specialised businesses operating within a tightly connected geography. Fabric mills, dyeing units, printing facilities, trim suppliers, garment workshops and logistics providers are close enough to respond to changes in demand almost in real time. A factory does not have to be large to participate. The system works because numerous small suppliers specialise in individual stages of production and can collectively deliver an integrated supply chain.

In Vietnam, production is more sophisticated, but the system remains less dense and is more dependent on imported Chinese fabrics, trims and other inputs. This creates a paradox. Moving garment assembly to Vietnam can reduce exposure to Chinese tariffs, but if the fabric, accessories and other inputs still originate in China, the supply chain remains partially anchored to the country it was intended to bypass.

Micro-batches change the economics

Traditional apparel sourcing generally rewards scale. A factory receives a sizeable order, schedules production, purchases materials and runs a predictable manufacturing cycle.

Ultra-fast fashion reverses that logic. Shein's competitive advantage depends on placing small orders, observing consumer behaviour and rapidly increasing successful styles. The supplier therefore has to absorb more frequent production changes and lower utilisation of its machinery. That model is viable in Guangdong because manufacturers have built their businesses around flexibility and extremely thin margins. Some suppliers can accept orders of only a few dozen pieces because they operate within an enormous surrounding of complementary businesses.

Vietnamese factories, in contrast, often require larger production runs to achieve acceptable economics. Longer lead times and lower flexibility can therefore make a garment that appears cheaper on a tariff sheet more expensive once its entire production cycle is considered. As Sheng Lu, professor of fashion and apparel studies at the University of Delaware, has argued, diversification beyond China has practical limits for companies whose competitive advantage depends on speed, flexibility and extremely small production runs.

That distinction matters for global brands. Nearshoring is much easier when a retailer can forecast demand several months ahead. It is considerably harder when the business model is based on discovering demand only after products reach consumers.

China responds with capital

Shein's retreat also shows how industrial clusters defend their competitive position. Instead of simply accepting the shift of suppliers, Guangdong has incentives to retain manufacturing activity, employment and investment. Shein has responded by committing over 10 billion yuan toward smart supply-chain infrastructure in the province.

The investment includes a logistics hub reported at about $504 million and a broader effort to digitise production and coordinate thousands of manufacturing partners. This is more than a conventional factory investment. It showcases an attempt to make the existing Chinese manufacturing segment even faster and more automated. That matters because China's advantage is no longer based solely on low labour costs. Automation, supplier density, logistics infrastructure, digital production scheduling and proximity to raw-material producers form the competitive divide. For Shein, strengthening that system may offer greater certainty than attempting to recreate it abroad.

Suppliers seek alternatives

The strain is also visible among manufacturers themselves. Small suppliers accustomed to Shein's tiny orders and narrow margins face greater pressure when international demand slows or logistics costs rise. Some are responding by reducing their dependence on a single platform and selling through other digital channels, including Temu and Amazon, while also returning to more conventional wholesale orders.

This reflects an important shift in platform economics. Shein originally transformed the supplier relationship by connecting thousands of small factories to a massive digital demand engine. But the same digital infrastructure can eventually give manufacturers access to competing platforms and direct customers.

The result could be a gradual rebalancing of power. Suppliers that once depended heavily on one ultra-fast-fashion platform now have more avenues to monetise their production capacity.

Nearshoring has a limit

Shein's Vietnam experience should not be interpreted as proof that nearshoring is failing. Vietnam remains a major apparel manufacturing hub and will continue to benefit from companies seeking geographic diversification. The more important conclusion is that nearshoring and replication are not the same thing.

A company can move sewing machines, warehouses and workers. It cannot instantly move the thousands of supplier relationships, specialised workshops, logistics routes, raw-material networks and accumulated manufacturing know-how that have developed in Guangdong over decades.

For conventional apparel, the cost advantage of Vietnam, Bangladesh, India and other sourcing destinations can outweigh the benefits of China's industrial density. For ultra-fast fashion, however, speed itself is a source of value. Shein's retreat therefore exposes a limit in the global China plus one strategy. Diversification can reduce concentration risk, but it may not replace the original production ecosystem.

As trade barriers rise and de minimis benefits disappear, the next phase of apparel sourcing will be less about finding the cheapest factory and more about finding the most efficient system. For ultra-fast retail, China's system remains difficult to beat.
