When Inner Mongolia Yili Industrial Group — one of China’s largest dairy companies — reported its first-half 2026 results, one line item grabbed the attention of every food business in China: a RMB 450 million retroactive enterprise income tax adjustment. The payment was not a fine, and it did not involve VAT. It was back tax arising from a stricter reading of one long-standing rule: which dairy products count as “preliminary processing” of agricultural products under Cai Shui [2008] No. 149. For foreign food and beverage companies operating in China, the case is a clear signal that product-level tax classifications are now being reviewed far more strictly.
- RMB 450 million: Yili’s one-off retroactive income tax adjustment for prior years, booked in its Q2 2026 results.
- RMB 630 million: the year-on-year increase in Yili’s Q2 2026 income tax expense (to RMB 860 million in total), which includes the retro adjustment.
- 24.5%: Yili’s effective income tax rate in H1 2026, up 11.93 percentage points year-on-year.
- January 1, 2008: the effective date of Cai Shui [2008] No. 149, the rule at the center of the case.
- Pasteurized and UHT pure milk: qualify as preliminary processing of agricultural products and are exempt from enterprise income tax.
- Yogurt, cheese, butter, cream and modified milk: classified as deep processing and do not qualify for the exemption.

What Happened: Yili’s RMB 450 Million Tax Adjustment
In its second-quarter 2026 financial report, Yili recognized a RMB 450 million adjustment to enterprise income tax covering prior years. Media coverage initially blurred two different numbers, so it is worth separating them clearly.
| Figure | What It Represents |
|---|---|
| RMB 450 million | One-time retroactive adjustment for prior-year income tax (the “back tax”), booked in Q2 2026 — not a current-period tax charge. |
| RMB 630 million | Year-on-year increase in Q2 2026 income tax expense, to RMB 860 million — this includes the RMB 450 million retro adjustment plus the normal uplift in the tax base. |
Research notes add context: Galaxy Securities reported that Yili’s first-half income tax expense rose by roughly RMB 750 million year-on-year, driven by updated tax enforcement standards and a higher tax base, while China Merchants Securities noted the 11.93 percentage point rise in the effective rate to 24.5%. Crucially, the adjustment involved enterprise income tax only — no VAT, no surcharges, and no disclosed penalties or late fees. It was a compliance re-classification, not a tax-evasion finding.
The Legal Basis: Cai Shui [2008] No. 149
The rule at the center of the case is the Notice of the Ministry of Finance and the State Administration of Taxation on Issuing the Scope of Preliminary Processing of Agricultural Products Eligible for Enterprise Income Tax Preferences (Trial) (Cai Shui [2008] No. 149), effective from January 1, 2008. It was issued to implement the enterprise income tax preferences for agriculture, forestry, animal husbandry and fishery projects under the Enterprise Income Tax Law of the People’s Republic of China.
The notice was published together with its annex, the Scope of Preliminary Processing of Agricultural Products Eligible for Enterprise Income Tax Preferences (Trial) (2008 Edition), which lists, product by product, the processing activities that qualify as “preliminary processing” — and, just as importantly, the products that are explicitly excluded. The full text of both documents is available on the official website of the State Taxation Administration system (for example, the publication on the Shanghai tax authority’s official website).
Which Dairy Products Qualify — and Which Do Not
The 2008 Edition scope is specific about milk. Under Item II(A)(3), “preliminary processing of milk” covers pasteurized milk and ultra-high temperature (UHT) sterilized milk produced from fresh milk through simple processing only — purification, homogenization, pasteurization or sterilization, and filling. In plain terms: pure milk qualifies for the enterprise income tax exemption.
The same section then excludes a list of products from the preferential scope, including all kinds of yogurt, cheese, butter (cream), and similar products. Industry analysis of the Yili case, as reported by 21st Century Business Herald, adds further categories that were re-classified as deep processing:
- Yogurt: produced through fermentation, which goes beyond simple sterilization and filling.
- Cheese and butter (cream): re-processing products rather than simple milk processing.
- Modified (flavored) milk: products with added sugar, flavorings or nutritional fortifiers, beyond plain fresh-milk processing.
The principle is consistent across the whole 2008 Edition: physical, simple treatment of agricultural products is preliminary processing; fermentation, extraction, modification and substantial addition of ingredients are deep processing. That principle applies far beyond dairy — to grain, fruits, oil plants, tea, meat and fishery products alike — which is why the annex matters to any food business in China, not just dairy companies.
Why Are Tax Authorities Reviewing More Strictly Now?
According to executives of several dairy companies quoted by 21st Century Business Herald, the tax enforcement standards are being updated nationwide, mainly through stricter review of the scope of the agricultural product preliminary processing preference. Part of the tax base of dairy companies grows when products previously treated as preliminary processing are re-classified as deep-processed products.
Two points matter for foreign-invested food companies in China. First, the exemption is determined product by product, not company by company — a dairy plant that makes both UHT milk and yogurt cannot apply the exemption to its yogurt revenue. Second, the re-classification was applied retroactively to prior years. The same industry sources indicate that the adjustment was not unique to Yili: comparable listed dairy companies reported similar income tax adjustments in the same period, confirming that this is an industry-wide implementation of a unified standard rather than a one-off audit.
What Foreign Food Businesses Should Do Now
If your China business processes, blends, packages or sells food products, the Yili case is a practical compliance checklist:
- Classify every product line separately. Map each product against the 2008 Edition scope and its exclusion notes, and document the reasoning.
- Separate your accounts. Exempt (preliminary processing) and non-exempt (deep processing) income must be accounted for separately, with costs allocated between them.
- Review past filings. If a product was historically treated as exempt but involves fermentation, extraction or added ingredients, expect the tax authority to revisit earlier years.
- Monitor updates. The notice itself allows the authorities to adjust the scope items over time; supplemental rules (for example Cai Shui [2011] No. 26) refine the coverage.
For companies setting up food operations in Guangzhou or elsewhere in China, getting the tax classification right at the planning stage is far cheaper than a retroactive adjustment later. A structured tax compliance review covering product classification, bookkeeping and tax filing is the practical starting point.
Frequently Asked Questions
Is milk production tax-exempt in China?
Only pure milk qualifies. Under Cai Shui [2008] No. 149, pasteurized milk and UHT sterilized milk made from fresh milk through purification, homogenization, sterilization and filling count as preliminary processing of agricultural products and enjoy the enterprise income tax exemption. Deep-processed dairy products do not.
Which dairy products do not qualify for the tax exemption?
Yogurt (fermented), cheese, butter and cream (re-processed products), and modified or flavored milk with added sugar, flavorings or nutritional fortifiers are all treated as deep processing and are excluded from the agricultural product preliminary processing exemption.
Does the exemption apply to my whole company or to each product?
It applies product by product, not to the company as a whole. A business that produces both exempt and non-exempt items must separately account for the income of each category and allocate costs accordingly.
Can Chinese tax authorities adjust previous years retroactively?
Yes. Yili’s RMB 450 million payment was a retroactive adjustment for prior years, booked in Q2 2026. If a product is re-classified from preliminary to deep processing, earlier years in which the exemption was claimed can be revisited.
What should a foreign food company in China do now?
Classify every product line against the 2008 Edition scope, separate exempt and non-exempt accounting, review past filings, and obtain a professional tax compliance review before the tax authority raises the question first.
If your company processes, packages or sells food products in China, a product-level tax classification review is the fastest way to avoid Yili-style adjustments.
