Understanding CO2 Cylinder Safety Certifications
Selling CO2 cylinders internationally isn’t just about manufacturing — it’s about compliance. Every market has specific certification requirements, and failing to meet them can result in product recalls, fines, and blocked shipments. This guide breaks down every certification you need to know.
DOT Certification (United States)
The Department of Transportation (DOT) regulates all pressure vessels sold in the US market. Key requirements:
- DOT-3AL specification for aluminum cylinders
- DOT-3AA specification for steel cylinders
- Hydrostatic test at 5/3 of working pressure
- Every cylinder stamped with DOT specification number
- Manufacturing facility must be DOT-approved
VS Cylinder products carry full DOT certification, with each cylinder individually tested and stamped.
CE Marking (European Union)
CE marking is mandatory for CO2 cylinders sold in the EU. It indicates compliance with:
- TPED (Transportable Pressure Equipment Directive) — 2010/35/EU
- Pressure Equipment Directive (PED) — 2014/68/EU
- Relevant harmonized standards (EN 1964, EN 13322)
Without CE marking, your cylinders cannot legally enter the EU market. The fines for non-compliance can reach €50,000+ per incident.
TPED Certification (International Transport)
The Transportable Pressure Equipment Directive applies to cylinders transported across borders. Requirements include:
- Periodic inspection regime (every 10 years for steel)
- Conformity assessment by a Notified Body
- PED category classification based on pressure × volume
- Manufacturing under quality assurance system (ISO 9001)
Food-Grade CO2 Compatibility
For cylinders used in beverage carbonation, food-grade certification is essential:
- Internal surface must be passivated or coated to prevent contamination
- CO2 purity must meet EIGA Doc 125 / ISBT standards (≥99.9%)
- Traceability from raw material to finished product
- No toxic residue from manufacturing process
Market-Specific Requirements
