China's consumption of corn has grown by leaps and bounds over the past decade, but China still has the same opaque corn import quota mechanism that was set up 25 years ago when farmers fed whatever was available to backyard pigs and chickens and the country was dotted with thousands of rudimentary feed mills. China has spawned dozens of feed and livestock companies--including most of the world's largest--spread across the country. China has also become the world leader in manufacturing corn-based starch, lysine, and citric acid.
China adopted a "tariff rate quota" (TRQ) system for imports of corn, wheat, rice, cotton and sugar when it joined the WTO in 2001. Trading partners envisioned the TRQ creating a small market-driven trade for commodities previously controlled by nontransparent bureaucratic mechanisms. China's corn TRQ allows a quota of up to 7.2 mmt to be imported at a low tariff of 1% while additional imports are subject to China's prohibitively high 65% tariff. Prospective importers have to apply every year for a share of the 7.2 mmt quota.
After many requests from frustrated trade partners for more transparency, the Chinese Government began posting lists of applicants for TRQs in 2015. Those lists did little or nothing to promote trade, but the lists at least provide a rare source of information on prospective buyers of corn.
In 2015, over 1,000 Chinese companies applied to import corn, and corn was the 2nd-most popular TRQ after cotton. From 2016 to 2020 the number of applicants dwindled to 778 when China was dumping a stockpile of domestic corn into the Chinese market and subsidizing processors to use the corn. Chinese interest in corn imports revived in 2021 after the stockpile was depleted, Chinese corn prices went up 80% in 2020, and China agreed to import corn as part of the Phase One agreement with the United States. At the same time China's corn processing industry expanded rapidly in tandem with recovery of the swine industry from the 2018-19 African swine fever epidemic and with ambitions to dominate the global industry for corn-based industrial products.

The actual import volume never hit the 7.2-mmt quota until 2020. Imports then exceeded the quota by a wide margin until 2024 with no explanation (imports would not have been viable at the over-quota tariff of 65%). The number of applicants increased to a peak of 1,453 requesting quota for 2025, but the lists do not reveal how much quota applicants requested nor how much they were able to import. Indications are that State-owned companies got most of the imports, even though the growth in corn demand was almost entirely among private Chinese corporations (see below). In 2025, applicants for corn quota had combined processing capacity of 453 mmt, but actual imports were slashed to 2.65 mmt -- the smallest volume since 2011 and again with no explanation. A slightly smaller number of 1,406 companies applied to import corn in 2026, but their processing capacity is still over 400 mmt. The corn TRQ attracted more applications than did the TRQs for wheat, rice, sugar or even cotton, demonstrating the hunger for imported corn in China.
The quota lists reveal that animal feed is the predominant use of corn by quota applicants. This year's list shows 329 mmt of combined processing capacity for applicants reporting feed as their main product. Manufacturers of corn-based industrial products also had substantial capacity: starch and corn sweeteners (35 mmt), lysine and other amino acids (15 mmt), citric acid and monosodium glutamate (11 mmt), and fuel ethanol (6 mmt). Comparing this year's list with the 2023 list previously analyzed by this blog shows processing capacity of feed manufactures declined slightly over 3 years, but capacity of industrial corn product manufacturers increased by a combined 37 mmt.

The same large feed companies that are expanding in the swine and poultry industries (see last week's post on the swine industry) are prominent applicants for corn imports. The TRQ rules require each production site of a company to submit a separate application for quota. The large number of applications submitted by branches of companies reflects the sprawling regional and national networks of feed operations established by Chinese companies. Last year Twins Group branches submitted 88 applications and Wens Food branches submitted 86. The increase in applications between 2023 and 2026 by Wens, Twins, Liyuan, New Hope and Zhengbang reflects expansion by those companies. Less prominent, but also notable, is the increase in capaciy by amino acid giants Meihua and Fufeng. Among the largest companies applying for corn import quota, the number of applicants and their processing capacity increased between 2023 and 2026. There were 10 companies whose processing capacity that exceeded the entire 7.2-mmt quota. (Note: these tabulations exclude capacity reported by several company headquarters that appears to double-count capacity.)
Feed and livestock industry leaders in China facing corn prices 50%-to-70% higher than in exporting countries (see chart below) occasionally dare to question the TRQ system. In 2019, for example, the chairman of no.2 (at the time) hog producer Zhengbang recommended TRQ reform to expand access to more corn imports to help Chinese livestock companies compete on a level playing field in the international market. He pointed out that Chinese corn is expensive due to high production costs, and growing it year after year--often with 2 crops in one year--degrades China's limited farmland. In 2022, the founder of feed company New Hope recommended lifting restrictions on corn imports from South America (which was done) and expanding the share of corn import quota available to private companies (which apparently was not done).
