Full Compliance for U.S. Import – DOT, CE & Food Safety
When purchasing a china 1.1l 640g steel cylinder for the American market, verifying DOT (Department of Transportation) approval is non-negotiable. Our cylinders carry DOT-3AL markings, meaning they are manufactured under a special permit compliant with 49 CFR § 178.37. Additionally, we provide:
- CE certification (ISO 9809-1) for international markets
- Food-grade gas compliance – all interior surfaces are cleaned and free of hydrocarbons (test certificate available)
- MSDS and COA in English for customs documentation
- ECM (European Conformity Module) documentation if needed
⚠ Note: U.S. importers should confirm that the cylinder’s valve meets CGA (Compressed Gas Association) standards. We can fit CGA 326 valves pre-installed – just specify at order.
