As an import manager or brand owner, you know that sourcing a china 9kg gas bottle requires more than just a low price – it demands consistent quality, proven certifications, and a supplier who understands U.S. compliance. With over a decade of experience supplying N₂O and CO₂ cylinders to global markets, we offer factory-direct 9kg gas bottles that meet DOT 3AA standards, deliver on time, and give you the flexibility to brand and spec your own product. Whether you’re filling whipped cream chargers or carbonating beverages, this page explains exactly what we provide, how we guarantee quality, and why our supply chain makes you more competitive.
Industry Pain Points – What Keeps Buyers Up at Night
Sourcing from China can feel like a minefield. Import managers at U.S. companies frequently report:
- Inconsistent cylinder quality – some suppliers deliver bottles that fail hydrostatic testing, leading to costly returns or safety hazards.
- Long, unpredictable lead times – a promised 30-day delivery can stretch to 60, disrupting your inventory flow.
- Certification gaps – non-DOT or non-TPED certified bottles cannot be imported into the U.S. legally.
- High minimum order quantities (MOQ) – you may be forced to buy 500+ units when you only need 100 for a pilot run.
- Language and documentation barriers – incomplete COA, MSDS, or customs paperwork causes delays at the port.

3. Flexible MOQ
For new customers, we accept MOQ of 100 pieces for standard gas bottles. Trial orders as low as 50 units are available for repeat clients.
4. Compliance Documentation
Every shipment includes Certificate of Analysis (COA), Material Safety Data Sheet (MSDS), hydrostatic test reports, and DOT or TPED certification. Customs clearance is smooth.

FOB Shanghai or CIF to major U.S. ports (Long Beach, New York, Houston). Payment via T/T (30% deposit, 70% balance before shipment) or L/C at sight. We also accept PayPal for small orders.
Application Scenarios – Where 9kg Gas Bottles Excel
The 9kg size hits the sweet spot between portability and capacity. Here’s how our customers use them:
- Whipped Cream Charging (N₂O): A 9kg N₂O bottle yields approximately 900 standard 8g cream chargers – perfect for commercial kitchens, bakeries, and catering wholesalers.
- Beverage Carbonation (CO₂): Soda fountains, draft beer systems, and home carbonation refill stations use 9kg CO₂ cylinders as a cost-effective alternative to small disposable cartridges.
- Diving Oxygen (O₂): While our primary focus is N₂O/CO₂, we also offer 9kg oxygen bottles certified for medical or diving use.
- Industrial Gas Supply: For welding, inerting, or laboratory applications where an 80lb cylinder is too heavy and a 5lb is too small, the 9kg bottle is the ideal middle ground.
Our 9kg gas bottle production line – quality inspected at every stage.
Comparison: 9kg vs Other Common Cylinder Sizes
| Cylinder Size | Fill Weight (N₂O) | Dimensions (D×H) | Empty Weight | Best For |
|---|---|---|---|---|
| 8g charger (disposable) | 8g | 2.5 cm × 7 cm | ~20 g | Single use, retail |
| 2 kg disposable | 2 kg | 120 mm × 300 mm | ~2.5 kg | Small catering events |
| 9 kg (ours) | 9 kg | 240 mm × 580 mm | ~12.5 kg | Commercial kitchen, beverage chain |
| 20 lb (9 kg) | ~9 kg (20 lb) | 250 mm × 600 mm | ~14 kg | Industrial / diving |
Note: The 20 lb cylinder (which holds roughly 9 kg of gas) is a common U.S. standard. Our 9kg bottle is designed to be cross-compatible with filling and valve equipment used in North America.
Trust Endorsement – Certifications, Customers, and Track Record
Our quality management system is ISO 9001:2015 certified; each cylinder carries DOT 3AA stamping.
FOB Shanghai – monthly container volume exceeds 50 TEU.
Since 2013, we have delivered over 1.2 million gas cylinders to markets in North America, Europe, Southeast Asia, and the Middle East. Our 9kg gas bottles are used by well-known whipped cream brands and beverage distributors. We maintain a ≤0.3% customer complaint rate and a 95% on-time shipment record.
What Our Customers Say
“We switched to XingYe’s 9kg N₂O bottles six months ago. The DOT certification was spot on, the hydro test reports came with each shipment, and the pricing gave us a 12% margin improvement. Lead time was exactly 28 days as promised.”
“I needed a custom valve setup and printed labels for my CO₂ tanks. XingYe’s OEM process was seamless – they sent me a digital proof in 3 days. The bottles look premium and work perfectly with our soda dispensers.”
“I’ve tested 9kg bottles from three different Chinese factories. XingYe’s wall thickness and valve finishing were clearly superior. Plus, they provide all Australian customs documents – never had a hold-up.”
“As a sourcing agent, reliability is everything. XingYe communicates clearly in English, responds to RFQs within 24 hours, and their factory tour video convinced me of their real manufacturing capability. Highly recommended.”
“We required TPED-certified 9kg cylinders for medical oxygen. XingYe provided full documentation and the bottles passed our internal inspection on the first try. We have placed three repeat orders.”
Author’s Perspective – Why This Factory Stands Out

Over the past decade, I have audited more than 30 gas cylinder factories in China, India, and Europe. Most factories can produce a 9kg bottle – the difference lies in repeatability. At XingYe, I was impressed by their in-house hydrostatic testing rig, the traceability of each batch, and their willingness to share real test data. They are not a trading company pretending to be a factory; they own the entire production line. For U.S. import managers who need a reliable source of china 9kg gas bottles that comply with DOT and TPED, I believe Zhuzhou XingYe Chemical is a safe, proven choice.
Packaging, Logistics & After-Sales Guarantee
- Packaging: Each bottle individually shrink-wrapped, with interlayer cardboard and edge protectors. Standard export pallet (1m×1m) holds 16 units of 9kg bottles. We also offer custom wooden crates for hazardous material shipping.
- Shipping: By sea, air, or rail. For U.S. customers, we recommend FOB Shanghai with a forwarder of your choice, or CIF to major ports. Average transit time: 25–30 days to Los Angeles / 35–40 days to New York.
- After-Sales: 12-month warranty against manufacturing defects. If any bottle fails hydrotest within 12 months of receipt, we replace it FOC (excluding freight). Our English-speaking sales team responds within 4 hours.
