1. To Understand Zhejiang's Food Processing, See That Its Inputs Lie at Both Ends Abroad

In most provinces, agricultural and sideline food processing hugs the land: where grain is grown, mills and oil presses follow; where hogs are raised, slaughtering and cutting follow; in big livestock provinces, feed mills follow. Processing grows where the raw material is. That "inputs decide processing" logic works for Henan, Shandong or Sichuan, but for Zhejiang the very first step calls for a different lens.

Zhejiang is seven-tenths mountain, one-tenth water and two-tenths field. Its plains suited to large-scale cultivation are limited, and land inputs such as soybeans, oilseeds and feed grain are not supplied from within the province. At the same time it is a small livestock province, so local demand for feed material such as soybean meal cannot sustain a large base. In other words, the two ends that decide the fate of this industry — upstream raw material and downstream feed consumption — both lie largely outside Zhejiang. By the usual logic, such a province would struggle to matter in primary food processing.

Yet Zhejiang has not sat it out; it took another road. With inputs at both ends abroad, it gripped the middle step — processing itself — firmly in its own hands. On one side, leaning on Zhoushan's deep-water harbours and the East China Sea distant-water grounds, it turns fish and soybeans hauled and shipped in from around the world into capacity right at the port. On the other, on land it has held a craft-gated niche: primary tea processing. So Zhejiang's food processing does not revolve around local fields but around ports and craft. The Tianxia Gongchang Industry Research Institute singles it out as a regional sample precisely because it differs entirely from the "land-based" processing of grain-rich provinces. This report endorses no company's market performance; it only sets out the real shape of this distinctive province.

2. Zhoushan: The Main Pillar Holding Up This Industry

There is no weighing Zhejiang's food processing without Zhoushan. This archipelago city carries, almost single-handedly, the thickest pillar of the whole province's primary food processing.

By 2024, Zhoushan had over a hundred above-scale aquatic processing enterprises and more than three hundred advanced production lines and sets of equipment, with processing capacity equal to roughly half the province's and about 4% of China's. For a single prefecture-level city to hold half of a major coastal province's aquatic processing capacity is uncommon nationwide. Behind it lies a dual supply of raw material from the East China Sea grounds and distant-water fishing: in 2023 the Putuo district alone produced 969,900 tonnes of aquatic products, of which distant-water output was 575,400 tonnes, up 5.2% year on year; Dinghai district's distant-water catch was 222,000 tonnes, up 18.4%. With raw material landed from the boats to the quay every day, Zhoushan was pressed to build its processing thick and dense.

What lets this pillar stand is a full port-side cold chain. The Zhoushan National Distant-Water Fishing Base holds a cold-store cluster of 550,000 tonnes capacity — the densest in the province — together with fuel-oil tanks and several ten-thousand-tonne dedicated wharves, linking catching, transport, storage, processing and trade into an unbroken chain. For food processing, the cold chain is no supporting role but the lifeline that decides whether perishable raw material becomes stable capacity: fish lose value the moment they leave the water, and without this cold-store cluster to catch them, Zhoushan's processing capacity could not exist.

3. The Full Chain of a Single Fish: From Distant-Water Catch to Deep Processing

Zhoushan's strength lies not only in volume but in having made a single category into a complete chain.

In 2024, Zhejiang's distant-water fishing economy reached RMB50.2bn in gross output, up 13.3%, keeping the province first nationally for a fifth straight year; the great bulk is concentrated in Zhoushan. The city has nearly seven hundred distant-water vessels and an annual catch of about a quarter of China's total, with squid in particular at around 70% of the national catch. Around these distant-water catches Zhoushan has formed three industry chains — squid, tuna and saury — each over RMB2bn in annual output, and the "single fish" full chain has passed RMB100bn in scale.

The chain's completeness shows precisely in the thickness of its processing. Zhoushan was not content to freeze the returning fish and sell them on; it ran from the most basic frozen goods all the way to higher-value deep-processed products such as fillets, seasoned and ready-to-eat lines, and built several fully automated production lines. In other words, the same distant-water squid can in Zhoushan be split into a whole row of processed products by different preservation and flavour needs. This "use every part of one fish" capability is the key that grew Zhoushan from a distant-water fishing base into a sample of the food-processing industry. Its upstream demand thus extends from vessels and gear to a full set of preservation, seasoning, packaging and cold-chain equipment.

4. The Zhoushan International Grain and Oil Park: Crushing Imported Soybeans Into Oil and Meal

Zhoushan's second face hides in the words "grain and oil" — and this part best illustrates the "inputs at both ends abroad" character of Zhejiang's food processing.

At the Zhoushan International Grain and Oil Industrial Park, soybeans imported from Brazil and elsewhere arrive at the deep-water port and, through pretreatment, leaching and refining, are processed on the spot into packaged soybean oil, with by-product meal becoming feed material. Local enterprises run these lines at full tilt — "one ship unloading, one in transit, one being processed." The raw material here comes almost entirely from overseas, relying on Zhoushan's deep-water harbours and port-side location to bring in others' soybeans and turn them into oil and meal in the local plant.

More telling is where the meal goes. Because Zhejiang is itself a small livestock province with limited local demand for feed material such as soybean meal, over 80% of the park's meal sells to other provinces — shipped via the Yangtze River to farms in Hubei, Chongqing and Sichuan. That is, in this segment Zhejiang plays a pure "processing transshipment" role: material comes from abroad, products go inland, and the province earns only the crushing step in the middle. This is the plainest picture of "inputs at both ends abroad, processing in hand." The grain-and-oil processors gathered in this park thus form a main body alongside aquatic processing in Zhejiang's food processing.

5. Primary Tea Processing: A Craft Niche Held on Land

Moving the view from the harbour back to land, Zhejiang's food processing also holds a craft-gated niche — the primary processing of tea.

In 2023, Zhejiang exported 150,300 tonnes of tea worth USD464m, both first nationally; green tea was the dominant share, with export volume of 144,300 tonnes, or 93.56% of the province's tea exports. That same year Zhejiang ranked first nationally in the share of premium-tea output value. For the most recognisable Longjing tea, 2023 plantation area was about 1.1m mu, output about 26,800 tonnes and output value about RMB6.2bn. Between fresh leaf and saleable rough or finished tea lie a full set of steps — fixing, rolling and drying — squarely within food processing, and the craft foundation that let Zhejiang make one leaf into the country's largest tea exports.

Primary tea processing stands in sharp contrast to the "port-side" aquatic and grain-oil segments: it depends not on harbours but on planting and tea-making craft passed down through generations, with raw material growing in the mountain plantations of western and southern Zhejiang. Put together, the three complete Zhejiang's food-processing map — the harbour side holds the largest-volume aquatic and grain-oil work, the land side the deepest craft in primary tea processing, each resting on different resource endowments.

6. Leaders and Upstream: The Procurement System Seen Through Zhoushan's Leaders

Pulling the clusters together, the shape of leadership in Zhejiang's food processing becomes clear: it concentrates heavily in Zhoushan and splits into two systems, aquatic and grain-oil.

On the latest list of national key leading enterprises in agricultural industrialisation, Zhoushan alone has several fishing- and grain-oil-related enterprises, spanning distant-water deep processing, aquatic wholesale trade and port-side oilseed crushing. These leaders each hold one segment — some turning distant-water catches into deep-processed food, some crushing imported soybeans into oil and meal — without betting on the same line. Add the tea-processing players scattered across western and southern Zhejiang, and Zhejiang's food processing shows a structure of "Zhoushan at the core, aquatic and grain-oil running in parallel, tea forming a separate pole."

This structure means its upstream procurement needs split into several non-overlapping systems:

  • Aquatic raw material and distant-water catch: squid, tuna, saury and other distant-water categories each carry different perishable-material and primary-processing requirements, with concentrated demand and ever-stricter standards on quality, specification and traceability year by year;
  • Preservation, seasoning and food ingredients: from the deep-processing seasoning of distant-water fish to the formulas for ready-to-eat aquatic products, a steady buyer of additives, seasonings and preservation ingredients;
  • Packaging materials: soft packaging for frozen aquatic goods, composite packaging for ready-to-eat products, bottles, cans and labels for small-pack edible oil — varied in type, large in volume, an easily underrated niche;
  • Processing and crushing equipment: from filleting lines and automated ready-to-eat aquatic lines to soybean pretreatment, leaching and refining equipment and tea fixing-rolling-drying units, spanning many craft types with rich layers of equipment procurement;
  • Cold chain and storage facilities: distant-water frozen goods and port-side grain and oil have a steady need for cold stores, oil tanks and cold-chain transport that grows in proportion to capacity.

Sales teams supplying these Zhejiang aquatic, grain-oil and tea processors can use Tianxia Gongchang to filter the factory directory and decision-maker contacts on the two dimensions of region and industry for Zhejiang's agricultural and sideline food processing, turning a firm-by-firm hunt across Zhoushan, western and southern Zhejiang, and the aquatic and grain-oil categories into mapped-out customer development.

7. The Institute's View: Inputs May Lie at Both Ends Abroad — the Processing Step May Not

Putting Zhejiang's food-processing pieces together, it takes a shape utterly unlike a grain-rich province: raw material does not come from local fields and downstream consumption lies largely in other provinces, yet it has set up in the middle step — processing itself — the thickest pillar in the whole province. Zhoushan ships in the world's fish and soybeans and turns them on the spot into deep-processed food and oil and meal; western and southern Zhejiang turn fresh leaf from mountain plantations into the country's largest green-tea exports. Harbour volume plus craft barriers let a province that seems to have "no raw-material advantage" instead hold a place in primary food processing.

Its worries are written in those same words, "inputs at both ends abroad." Distant-water catches are bound by high-seas resources, quotas and fishing costs, with prices harder to smooth than inshore material; the imported-soybean line ties its raw-material end to global shipping and exchange rates and its sales end to inland livestock cycles, with neither in its own hands, so once either tightens, the margin on port-side crushing is squeezed thin; tea exports must face overseas technical trade barriers and green thresholds.

The Institute's view is this: the real weight of Zhejiang's food processing lies not in how much grain it grows or how many hogs it raises within the province, but in whether it can keep making "processing" — the step others cannot replace — thicker and finer. Whether Zhoushan's distant-water fish can grow from bulk frozen goods into more ready-to-eat, branded, high-value products; whether port-side grain and oil can move beyond the hard-earned crushing fee toward deeper food industry; whether Zhejiang's green tea can climb another step in finishing and branding. For a province whose inputs lie at both ends abroad, the thickness of the processing step is very nearly its entire hand in this industry — hold that step, and Zhejiang holds its place on the food-processing map.
