CO₂ Cylinder Gas – Food-Grade & Industrial Carbon Dioxide Supply for USA Buyers
Last updated: 2026
CO₂ cylinder gas is essential for beverage carbonation, food packaging, welding, and medical applications. If you are sourcing carbon dioxide cylinders for your business – whether you need consistent purity, reliable DOT/ISO certification, or competitive pricing from a proven Chinese manufacturer – this page covers everything you need to know. From technical parameters and compliance documents to MOQ, lead time, and OEM options, we provide transparent, verifiable information so you can make an informed procurement decision.

Why Sourcing CO₂ Cylinder Gas Demands Careful Evaluation
Import managers and brand owners looking for bulk CO₂ cylinder gas often face three major challenges:
- Certification gaps – cylinders lacking DOT (USA) or TC (Canada) approval cannot be legally filled or transported.
- Inconsistent purity – food-grade CO₂ requires ≥99.9% with no residual contaminants; industrial CO₂ may have varying spec.
- Long lead times – many overseas suppliers promise 30 days but deliver in 60+, hurting your production schedule.
At Zhuzhou XingYe Chemical, we address each of these pain points head‑on with a traceable quality system and long‑standing experience serving US importers since 2014.

What Our USA Buyers Say
Import Manager, Midwest Beverage Co.
“We tested three Chinese CO₂ suppliers before XingYe. Their food-grade CO₂ cylinder gas arrived with perfect purity, and they actually provided the COA before shipping – no other supplier did that. Lead time was 18 days from deposit to port.”
Brand Owner, Craft Soda Line
“OEM labeling was seamless. XingYe printed our logo on the cylinders, used CGA-320 valves, and the cylinders passed our local (US) retest without any issue. Highly recommend their CO₂ supply.”
