Taiwan Sugar: From the Sweet Empire That Propped Up 74% of Foreign Exchange to the "Unconventional" Major Landlord With Record 2025 Profits

30-Second Overview: In the 1950s, 74 out of every 100 NT dollars of Taiwan’s foreign exchange came from Taiwan Sugar’s sugar exports. Today, Taiwan Sugar’s sugar business runs an annual deficit, yet in 2025, it achieved a record high profit of NT$7.468 billion through fuel products, orchids, and land development. This largest landlord in all of Taiwan is pivoting from a "sugar manufacturer" to a leader in "circular economy."

"Train arriving, please step back! Watch your step when boarding and alighting!" At Tainan Wushulin Station, 92-year-old Honorary Station Chief Lin Haixi still stands tall, waving the red and green flags in his hand ¹. He started working at Wushulin at age 16 and has spent a full 60 years there; even when delivering betrothal gifts to his wife’s family back in the day, he requested the use of Taiwan Sugar’s "Type 109 Track Inspection Car" for a romantic escort ². Lin Haixi’s life is deeply intertwined with Taiwan Sugar, and his red and green flags have witnessed the century-long trajectory of Taiwan’s sugar industry, from its peak to decline, and then to its glorious transformation.

The Sweet Backbone: Propping Up Half of Taiwan’s Foreign Exchange

In that era of "using agriculture to support industry," Taiwan Sugar was more than just a company—it was Taiwan’s national treasury. In the 1950s, the export value of sugar once accounted for 74% of Taiwan’s total foreign exchange income ³. Back then, on the Jianan Plain, a dense web of narrow-gauge sugar railway tracks connected self-operated farms and contract sugarcane fields, with massive sugar refineries towering over the fields—this was the peak of Taiwan’s sugar industry economy ⁴.

However, this sweetness came at a cost. During the Japanese colonial period, Taiwan Sugar served as a tool for the colonial mother country; after the war, it became a cash cow for the government to regulate the economy. To protect sugarcane farmers, Taiwan Sugar long purchased sugarcane at a cost higher than the international sugar price, trapping its core business in a cycle of inevitable losses. With fluctuations in international sugar prices and rising domestic labor costs, sugar refineries closed one after another. Of the more than 40 sugar refineries across Taiwan, only a few such as Huwei and Shanhua remain in operation today ⁵.

📝 Curator’s Note: The history of Taiwan Sugar is a microcosm of Taiwan’s economy—from a land-dependent primary industry, forced to survive in the cracks of the international market.

Moth Orchids and Clam Essence: When "Unconventional Sidelines" Become the New Core Business

When sugar lost its sweetness, Taiwan Sugar began seeking opportunities in "side businesses." Surprisingly, this sugar manufacturer has become a global hub for moth orchid breeding. At the 2025 Taiwan International Orchid Show, Taiwan Sugar won 14 awards in one fell swoop, with its "Taisugar Grandma" variety being a classic, long-standing favorite in horticultural circles ⁶.

Biotechnology is another highlight of its transformation. Leveraging core technologies from sugar production and pig farming, Taiwan Sugar developed clam essence with a market share once exceeding 60%. It even converts waste such as fish scales and oyster shells into collagen and high-value-added products through specialized processes ⁷.

"This is not a technical issue; it is a story about trust."

When the Cimbuterol lean meat powder incident broke out in 2024, Taiwan Sugar’s brand integrity was temporarily called into question. However, after 84 subsequent samples all tested negative, and the court ruled that only a single box of samples was contaminated, the controversy instead strengthened consumer confidence in Taiwan Sugar’s domestically produced pork ⁸.

Taiwan’s Largest Landlord: Cultivating "Circular Economy" on Its Land

With approximately 50,000 hectares of land, Taiwan Sugar is rightfully Taiwan’s "largest landlord." But it no longer just lives off selling ancestral assets; instead, it is beginning to experiment with coexisting symbiotically with the land.

In Tainan Shalun, Taiwan Sugar has promoted Taiwan’s first "Smart Green Energy Circular Residential Park." This development does not follow the traditional model of buying and selling, but instead uses a "rent-to-own" model. All building materials are tagged with traceable IDs, and can be recycled and reused after future demolition. This project even appeared at the Milan Design Week in Italy in 2026, showcasing Taiwan’s sustainable architecture capabilities to the world ⁹.

📝 Curator’s Note: From selling sugar to renting housing, Taiwan Sugar is learning how to no longer "consume" land, but to "cycle" value.

Conclusion: The Lingering Resonance of a Century-Old Enterprise

In 2025, Taiwan Sugar’s operating profit reached NT$4.698 billion, with after-tax net profit hitting a record high of NT$7.468 billion ¹⁰. Although a large portion of this comes from non-operating investments and land development, Taiwan Sugar’s deployments in biotechnology and green energy are helping this century-old enterprise shed its "millstone" label.

When we ride the 10 km/h narrow-gauge sugar railway at Wushulin, watching Station Chief Lin Haixi wave his green flag, that slow-living rhythm reminds us: Taiwan Sugar may no longer be the all-powerful sweet empire it once was, but it is guarding the past and future of Taiwan’s land in a more resilient way.
