For Kazakhstan's grain deep processing to scale up, the choke point is not capacity targets but whether the raw material fits and which route the products take out of the country. In January–September 2026, Kazakhstan Temir Zholy railways exported 8.4 million tonnes of grain, only 750,000 tonnes of it to China; yet the government plans to raise deep-processing feedstock from 510,000 to 5.8 million tonnes by 2029. Four numbers explain the arithmetic: 750,000 tonnes (how small the grain flow to China is), 5.8 million tonnes (how much grain deep processing would absorb), 321,000 tonnes (the feedstock gap Chinese-funded plants already face), and 20 million tonnes (what a third rail border crossing with China could change).

1. 750,000 tonnes: why is Kazakhstan's grain export to China so small?
The Ministry of Transport of Kazakhstan reported on 7 October: rail grain exports in January–September were 8.4 million tonnes, up 14% year on year; of this, 5.5 million tonnes went to Central Asia, 762,000 tonnes to Afghanistan and 750,000 tonnes to China, up 54% year on year (see #258 Rail grain exports of 8.4 million tonnes in the first nine months).
Put this number against three larger ones:
| Comparison | Figure | Source |
|---|---|---|
| 2026 total grain output | 24.3 million tonnes, about 10% below 27 million tonnes in 2025 | Ministry of Agriculture, reported by Kazakhstan Today and Interfax Kazakhstan on 30 October |
| Grain and flour exports in the last two market years (grain equivalent) | 15.5 million tonnes and 16 million tonnes | Same |
| Rail grain exports in January–September / of which to China | 8.4 million tonnes / 750,000 tonnes (about 8.9%) | Ministry of Transport (#258) |
| Total Kazakhstan→China rail freight in January–September | 17.6 million tonnes | KTZ (see #245 35th meeting of the China–Kazakhstan border railway commission) |
| Grain share of Kazakhstan→China rail freight | about 4.3% (750÷17,600, calculated for this article) | Derived from the two rows above |
Chinese data point the same way. According to Chinese customs data compiled by Hubei Grain Network, China imported 3.8508 million tonnes of wheat in 2025, down 65% year on year, of which Canada supplied 2.7126 million tonnes and Australia 1.0206 million tonnes, with all other sources together only 117,600 tonnes; Kazakh wheat accounted for 3.60% of monthly wheat imports in August and 0.71% in November (compiled from customs data by China Grain Net).
There is a mismatch here: on this basis China's wheat imports from Kazakhstan in 2025 were no more than 117,600 tonnes, while Kazakhstan's statistics show 750,000 tonnes of "grain" shipped by rail to China in the first nine months of 2026. Inference: non-wheat items such as barley and oilseeds may make up most of the "grain" shipped to China, or China's wheat imports from Kazakhstan may have risen sharply in 2026. What needs verifying is KTZ or Ministry of Transport shipment data by commodity, and Chinese customs data on wheat and barley imports from Kazakhstan for January–September 2026.
Opinion: Kazakhstan's grain exports flow mainly south to Central Asia and the raw-grain channel to China is narrow; companies in grain trade with China should first be clear about which commodity they are dealing in.
2. 5.8 million tonnes: how much exportable grain will the deep-processing target absorb?
Agriculture Minister Saparov told the government meeting on 29 October that the country currently has 3 grain deep-processing companies processing a combined 510,000 tonnes of feedstock a year; by 2029 six large projects are planned, processing 5.8 million tonnes a year, with products including starch, wheat gluten, bioethanol and amino acids (see #307 Six large grain deep-processing projects by 2029). At the same meeting the Prime Minister ordered a list of deep-processing projects within a month, stating potential investors, implementation deadlines and localisation levels (see #314 Unified investment management system and the deep-processing project list).
| Indicator | Figure | Calculated for this article |
|---|---|---|
| Deep-processing feedstock: now → 2029 target | 510,000 → 5.8 million tonnes | about 11.4 times |
| 5.8 million tonnes as a share of 2026 grain output (24.3 million tonnes) | — | about 24% |
| 5.8 million tonnes as a share of exports in the latest market year (16 million tonnes, grain equivalent) | — | about 36% |
Seen another way: if the 5.8 million tonnes materialise as planned, more than a third of a market year's export volume would shift from raw-grain export to domestic processing. Inference: the press release does not disclose how much of the 5.8 million tonnes is wheat and how much is maize, or in which region each of the six projects will be; if maize dominates, the squeeze on wheat exports would be much smaller. What needs verifying is the deep-processing project list the Ministry of National Economy is to produce within a month.
Opinion: the 5.8-million-tonne target is less a matter for the processing industry than for export structure; Chinese traders signing purchase contracts should build "policy steering raw grain to stay in the country" into their medium- and long-term assessment.
3. 321,000 tonnes: what feedstock do Chinese-funded deep-processing plants lack?
Fufeng Group's maize deep-processing project in Shu district, Zhambyl region, is the largest Chinese-funded example in this round. The parameters disclosed by different parties differ, so they should be read separately by date:
| Time | Disclosed by | Investment | Maize processing capacity |
|---|---|---|---|
| Construction start, April 2025 | Kazakh Invest national investment company | USD 800 million | 1 million tonnes a year |
| At the presidential video launch | Qazinform, citing the Presidential Administration | Phase I USD 350 million; Phase II USD 1.15 billion | Phase I 500,000 tonnes a year, Phase II expanding to 3 million tonnes a year |
| April 2026 | Zhambyl regional government, reported by The Astana Times | USD 1.5 billion in total | 3 million tonnes a year at full output |
Feedstock is where the gap lies. According to Kazakhstan's agricultural news site on 11 September, Fufeng's Phase I is designed for 500,000 tonnes a year, Zhambyl region's 2026 maize harvest is expected at 179,000 tonnes, and the difference of 321,000 tonnes is to be bought from Almaty, Zhetysu and Turkistan regions; the purchase price is 95 tenge per kilogram plus a 20-tenge state subsidy (single source, awaiting confirmation by a regional government or company announcement).
Flipping the perspective: Kazakhstan's 24.3 million tonnes of grain are mainly wheat, while maize has to be moved between regions. For exporters, the deep-processing policy is a competition for feedstock; for a processor like Fufeng, what is truly scarce is exactly not the part of the harvest in which Kazakhstan is "grain-rich". The same "grain power" label means ample supply for wheat traders and feedstock shortage for maize processors. The silo and oil-plant expansion that China's Aiju Group is negotiating in North Kazakhstan region (about 2 billion tenge, still at the negotiation stage, see #269 Aiju Group negotiates silo and oil plant in Tayynsha district) is sited in a wheat and oilseed growing area and takes the other route of sourcing locally.

Opinion: in Kazakh grain deep processing, choosing the product category decides success earlier than choosing the site; where the feedstock differs from the locally grown crop, inter-regional purchasing and growing contracts must be priced into costs.
4. 20 million tonnes: what can a third rail border crossing with China change?
The Ministry of Transport said on 30 October that earthworks on the Bakhty–Ayagoz railway are 92% complete; the line is 303 km long and due to open in 2027 with a design capacity of about 20 million tonnes a year, becoming the third rail border crossing between Kazakhstan and China and relieving cargo flows at Dostyk and Altynkol (see #300 Progress on the Bakhty–Ayagoz railway). At the China–Kazakhstan border railway commission, KTZ proposed setting the 2027 Kazakhstan→China volume at 26.8 million tonnes, markedly above the 17.6 million tonnes of January–September 2026 when annualised (#245). By road, after Zhetysu region diverted some incoming vehicles to processing at the Khorgos International Border Cooperation Centre, the load on the Nur Zholy crossing fell by about 30% (see #264 Nur Zholy crossing diversion pilot).
When crossing capacity is limited, "how much a tonne of cargo is worth" matters more than "how many tonnes can be moved". Below is an estimate of the tonnage of main products leaving the country after 5.8 million tonnes of feedstock are processed:
| Route | Main-product yield per tonne of feedstock | Main product from 5.8 million tonnes of feedstock | Relative to feedstock tonnage |
|---|---|---|---|
| Bioethanol | About 2.68–2.69 kg of wheat per litre of ethanol, i.e. about 372 litres per tonne; ethanol density about 0.789 | About 2.16 billion litres, about 1.7 million tonnes | About 29% |
| Starch + wheat gluten | Starch content about 65% × recovery about 85% ≈ 0.56 tonnes; wheat gluten about 0.10 tonnes | Starch about 3.25 million tonnes + wheat gluten about 580,000 tonnes ≈ 3.83 million tonnes | About 66% |
Assumptions of the estimate: ethanol yield per tonne of feedstock, starch content and recovery, and wheat gluten yield are all industry rule-of-thumb values, not project-disclosed data. The ethanol yield refers to figures for Canadian and Australian wheat-ethanol plants (2.68–2.69 kg per litre) listed in "Ethanol production from grain" by the Western Australia Department of Primary Industries and Regional Development; research by the USDA Agricultural Research Service gives fermentation yields of 368–447 litres per tonne of wheat; starch recovery refers to a 2002 wheat wet-milling experiment in Cereal Chemistry (85.6%); wheat gluten yield is a rough estimate assuming about 12% wheat protein and 80%–85% recovery (a 2024 wheat wet-milling study in Fermentation). By-products such as distillers' grains and bran are not counted, and wheat and maize routes are not distinguished.
Cross-check: the main-product tonnage of the two routes is only about one-third to two-thirds of the feedstock, and the 5.8 million tonnes of feedstock itself equals only 29% of the third crossing's design capacity (20 million tonnes). Inference: once deep processing is in place, the same crossing capacity can carry higher-value cargo. Kazakh Invest says lysine, monosodium glutamate and similar products are priced 10–15 times raw grain (an agency statement, no independent data seen); whether the products actually go to China, Central Asia or Europe depends on the investors and sales contracts of the six projects.
Opinion: until the third rail crossing to China opens in 2027, crossing capacity remains the bottleneck; the same bottleneck is a cost for raw-grain exporters and a filter for companies that process in Kazakhstan before exporting.
Four questions to ask before signing
- (Section 1) What share of the "grain" shipped by rail to China is the commodity I deal in? Is there Chinese customs data on imports of that commodity from Kazakhstan?
- (Section 2) Is my raw-material source within the purchasing radius of the six large deep-processing projects? Once the Ministry of National Economy's project list appears, will feedstock competition push prices up?
- (Section 3) Is the raw material the region's main crop, or must it be moved between regions? Who bears the purchase price, subsidy and growing-contract risk, and where is it written down?
- (Section 4) Before the third crossing opens in 2027, will my cargo go via Dostyk, Altynkol or a road crossing? Is the volume plan in the minutes of the China–Kazakhstan border railway commission?
