Shuangtong Plastics fired Walmart and Dollar Tree to sell to small buyers

Shuangtong, a plastic-straw manufacturer founded in Yiwu, Zhejiang, grew through the late 1990s and early 2000s by winning orders from major Western retailers, including Walmart and Dollar Tree — exactly the kind of marquee accounts most small Chinese exporters chased. On paper the factory was thriving: production capacity kept expanding to meet the volume these retailers demanded. In practice, margins told a different story.

By the early 2000s Shuangtong was larger by volume than it had ever been and less profitable than it had ever been, caught in a trap common to manufacturers who scale by serving retail giants: the customer relationship that looks most like success is also the one doing the most damage to the bottom line, and growing the relationship further only tightens the squeeze.

Fired Walmart and Dollar Tree, sold to thousands of small buyers via Alibaba, trading a few powerful customers for many who lacked leverage, restoring margins to 20%.

Big buyers used volume to force prices down to near cost.

Small buyers individually lack leverage, so Shuangtong set prices.

Alibaba's platform let Shuangtong reach thousands of small buyers cheaply.

Diversified base meant no single customer could threaten revenue.

When a customer's volume gives it pricing power over you, that relationship's profit contribution may be negative; deliberately diversify into many small buyers who can't dictate terms.

Shuangtong's customer base grew to more than 20,000 documented buyers, with sales split roughly 50-50 between domestic and export markets instead of concentrated in a handful of foreign retail accounts. Net margins recovered to roughly 20%, a dramatic rebound from the near-zero margins the big-box relationships had left the company with.
