Market
Food-grade carbon dioxide (CO₂; E290/INS 290) is used in Vietnam primarily for beverage carbonation and certain food-processing applications. In February 2026, Petrovietnam Ca Mau Fertilizer Corporation (PVCFC; HOSE: DCM) commissioned a food-grade CO₂ recovery-and-purification project at the Ca Mau Fertilizer Plant and shipped an initial commercial batch, indicating growing domestic supply capability. The project output is liquid CO₂ produced from recovered CO₂ streams in the urea process and commercialized via an off-take partnership with Messer Vietnam. Compliance expectations are anchored in Vietnam Ministry of Health food-additive management rules and are commonly benchmarked against Codex/JECFA references for identity and purity.
Market RoleDomestic producer and industrial consumer market (food-grade CO₂ supplied via industrial-gas producers/distributors; increasingly supported by by-product recovery projects linked to fertilizer/urea production)
Domestic RoleIndustrial input for beverage manufacturing and food processing; supplied as liquid CO₂ via bulk distribution networks
Specification
Physical Attributes- Supplied for industrial food use as liquid CO₂ (LCO₂) for bulk storage and distribution.
Compositional Metrics- Food/beverage-grade quality is commonly benchmarked to ISBT specifications; PVCFC reports its LCO₂ meets ISBT food-grade requirements and cites independent analytical testing results.
Grades- Food-grade / beverage-grade CO₂ (ISBT-referenced specification)
Packaging- Bulk liquid CO₂ (cryogenic tanks / tanker distribution)
- High-pressure cylinders (channel-dependent)
Supply Chain
Value Chain- Urea plant CO₂ stream recovery (permeate/flash gas) → purification (moisture/impurity removal, scrubbing, drying) → liquefaction → bulk storage → industrial gas distribution → beverage/food manufacturing use
Temperature- Liquefaction and bulk handling require disciplined cryogenic/pressurized storage and transport; PVCFC describes liquefaction using an NH₃ (R717) refrigeration system as part of its process.

Risks
Supply Continuity HighFood-grade CO₂ supply in Vietnam can be structurally dependent on the operating stability of upstream industrial plants that generate recoverable CO₂ streams (e.g., urea/fertilizer production). If an upstream plant experiences outage, maintenance shutdown, or process disruption, recovered-CO₂ output can drop sharply, disrupting beverage/food production schedules that rely on continuous CO₂ availability.Qualify at least two independent CO₂ supply sources (separate upstream sites), require emergency cylinder/tanker back-up arrangements via distributors, and maintain a contingency inventory plan aligned to plant shutdown calendars.
Logistics MediumCO₂ is freight- and handling-intensive (pressurized/cryogenic bulk logistics). Delivery disruptions (tanker availability, cylinder turnaround, hazardous handling compliance) can cause line stoppages for carbonation-dependent beverage plants.Lock in transport capacity and cylinder pools via long-term distributor contracts; implement site-level redundancy (backup manifold/cylinder banks) for critical production lines.
Regulatory Compliance MediumNon-conformance with Vietnam food-additive management and import inspection/documentation requirements can delay clearance or restrict market circulation (e.g., incomplete declaration dossiers, missing test results, or misalignment with permitted-use conditions).Map the product to the applicable Ministry of Health frameworks (Circular 24/2019 and Circular 28/2021), keep declaration dossiers current, and align COA/specifications to recognized references (ISBT; Codex/JECFA).
Sustainability- Circular economy / emissions utilization: capturing and purifying CO₂ from industrial process streams (e.g., urea production) to create food-grade CO₂ rather than venting
- Corporate climate reporting sensitivity: buyers may scrutinize whether CO₂ is recovered (by-product) versus produced from combustion, and may request footprint disclosures
Labor & Social- Occupational safety risk in pressurized/cryogenic gas operations (cylinder/tank handling, transport safety, contractor safety management)
Standards- ISBT beverage-grade CO₂ specification (commonly used by beverage industry buyers)
FAQ
What is the most notable recent development for food-grade CO₂ supply in Vietnam?In early February 2026, Petrovietnam Ca Mau Fertilizer Corporation (PVCFC) commissioned a food-grade CO₂ production project at the Ca Mau Fertilizer Plant and delivered an initial commercial batch. PVCFC states the product is liquid CO₂ intended for beverage production and premium food processing, commercialized with Messer Vietnam as the off-take partner.
Which international reference systems are commonly used to identify carbon dioxide as a food additive?Carbon dioxide is identified in the WHO JECFA database as INS 290, and it is covered within the Codex General Standard for Food Additives (Codex STAN 192-1995 / GSFA framework). In beverage supply chains, buyers often use ISBT beverage-grade specifications for food-grade CO₂ quality expectations.
Which Vietnam legal instruments are key starting points for food additive management and import inspection mapping?Vietnam Ministry of Health Circular 24/2019/TT-BYT sets the management framework for food additives (including permitted lists and use principles), and Circular 28/2021/TT-BYT provides a list approach linking foods/food additives to commodity codes for state inspection of imported foods. Decree 15/2018/ND-CP details implementation provisions of the Law on Food Safety, including declaration/administrative pathways relevant to products such as food additives.
