8.5 kg Gas Bottle: Specs, Compliance, and Sourcing Guide for US Buyers (2026)
If you are sourcing an 8.5 kg gas bottle for commercial cream charging, beverage dispensing, or industrial gas supply, you need a cylinder that meets US DOT/UN standards, offers reliable valve performance, and fits your logistics cost structure. This guide covers technical parameters, compliance certifications, MOQ, lead times, and OEM support from a certified Chinese factory — so you can evaluate suppliers without guesswork.

Why the 8.5 kg Gas Bottle is in High Demand for US Commercial Use
| Application | Gas Type | Common End-Users | Key Requirement |
|---|---|---|---|
| Whipped cream / nitro coffee | N₂O (Nitrous Oxide) | Dessert shops, coffee chains, caterers | Food-grade purity, NSF/FCN |
| Beverage carbonation / draft beer | CO₂ (Carbon Dioxide) | Breweries, bars, soda fountains | Beverage-grade, CGA valve |
| Welding / shielding gas | Argon, CO₂, or mix | Fabrication shops, automotive repair | High pressure, DOT 3AA |
| Medical / dental sedation | N₂O (Medical-grade) | Clinics, hospitals | USP/NF, FDA registration |
The 8.5 kg gas bottle size sits in the “mid-range” category — portable enough for daily use yet large enough to reduce cylinder changeover frequency. US import managers and wholesalers increasingly prefer this format because it balances freight cost per unit with end-user convenience.

Addressing Common Buyer Concerns
❓ “How do I verify the cylinder meets US DOT standards?”
Each cylinder is stamped with DOT 3AA or UN ISO 9809-1 certification, serial number, and hydrostatic test date. We provide a copy of the batch certificate of compliance (CoC) from the accredited testing lab. For food-grade N₂O or CO₂, we also supply a Certificate of Analysis (COA) showing purity ≥99.9%.
❓ “What are the shipping costs for a container of 8.5 kg bottles?”
A standard 20-foot container holds approximately 450–520 pcs of 8.5 kg cylinders (palletized). Freight cost per unit FOB Shanghai is typically competitive; we can provide a real-time CIF quote to your nearest US port. Contact us with your destination and volume for an accurate estimate.

❓ “Can I get a private label with my brand on the cylinder and packaging?”
Yes. We offer full OEM: your logo, brand name, and regulation text can be printed on the cylinder body (epoxy label or direct screen print) and on the outer carton. Minimum for custom label is 200 pcs.
❓ “What is your quality assurance process before shipment?”
Every cylinder undergoes: (1) hydrostatic pressure test, (2) leak test with helium detection, (3) valve function test, (4) visual inspection, (5) gas composition analysis (for filled cylinders). We follow ISO 9001:2015 procedures, and third-party inspection (SGS/BV) is available at buyer’s request.
8.5 kg Gas Bottle vs. Other Common Cylinder Sizes
| Gas Weight | Typical Water Capacity | Best For | Shipping / Storage |
|---|---|---|---|
| 8 g (disposable) | N/A | Home use, single-use charger | Light, small, high volume |
| 580 g – 680 g | ~0.8 L | Small café, light use | Portable, low per-unit margin |
| 8.5 kg (this product) | ~10 L | Commercial kitchens, bars, workshops | Best freight-weight balance |
| 2,000 g (2 kg) | ~2.5 L | Medium restaurants, mobile | High per-unit margin, niche |
| 20 kg / 50 lb | ~23 L | High-volume production | Heavy, less frequent refill |
What US & EU Buyers Say About Our 8.5 kg Gas Bottles
Michael R. — Import Manager, GourmetWhip Inc. (California, USA)
“We tested 8.5 kg N₂O bottles from three suppliers. XingYe’s cylinders had the most consistent tare weight and the valve threads matched CGA 320 perfectly — no adapter needed. The COA showed 99.97% purity. Our first order of 300 units arrived in 22 days FOB, and we’ve reordered twice.”
Sarah van der Linden — Brand Owner, PureCream B.V. (Netherlands)
“We needed a private-label 8.5 kg bottle for our premium whipped cream brand. XingYe handled the custom epoxy labeling and even adjusted the valve cap design per our request. Lead time was 35 days, and the EU TPED certification was already in place. Very professional.”
James Kowalski — Sourcing Manager, Tri-State Gas Supply (Texas, USA)
“We distribute to welding shops and beverage supply houses. The 8.5 kg CO₂ bottle is a sweet spot — easy to handle and fits our customers’ standard American regulators. The price was competitive even with the DOT 3AA stamp. Payment by L/C was smooth.”
Ana G. — Wholesale Buyer, FiestaGas Distribution (Florida, USA)
“I’ve imported from China for 6 years. XingYe is one of the few suppliers who sends the paperwork (COA, MSDS, and DOT cert) before the container arrives. The 8.5 kg bottles sold out in 3 weeks through our wholesale channel. We are planning a 700-unit order.”
