Oxygen Tank for Scuba: Trusted B2B Supply from China’s Leading Gas Cylinder Factory
By James Hartley | Industry Analyst & Gas Equipment Sourcing Specialist | Published 2026
When searching for an oxygen tank for scuba, B2B buyers need a reliable supplier who delivers consistent purity, certified safety, and cost-effective bulk pricing. At Zhuzhou XingYe Chemical Co., Ltd, we produce high-pressure diving oxygen cylinders that meet international standards (ISO 9809, DOT, CE). With over 10 years of expertise in specialty gases and a dedicated factory in Hunan, China, we offer OEM/ODM customization, fast lead times, and competitive FOB/CIF terms for import managers and brand owners worldwide.
Why B2B Buyers Struggle with Scuba Oxygen Tanks – And How We Solve It
Importing scuba oxygen tanks from overseas involves more than just finding the lowest price. Sourcing managers and brand owners consistently face these challenges:
- Unverified gas purity – Contaminated oxygen can cause equipment failure or health risks beneath the surface.
- Missing or fraudulent certifications – Without proper ISO, DOT, or CE marks, US importers risk customs holds and liability.
- Inconsistent cylinder quality – Wall thickness, valve threads, and hydrostatic test failures lead to returns and lost time.
- Long lead times & inflexible MOQs – Many factories require 1,000+ units and 60-90 days, which kills cash flow.
- Poor after-sales service – Once the container leaves the port, manufacturers vanish when you need support.
Our solution is built on Chinese supply chain excellence combined with Western compliance standards. We offer scuba oxygen tanks with guaranteed ≤99.5% purity (medical-grade) and full traceability, backed by COA, MSDS, and third-party certification. Below we break down exactly what we deliver.

Real Reviews from Our Global Partners
Owner, Deep Blue Scuba Gear, Florida, USA
“I was skeptical about importing oxygen tanks from China after a bad experience with another supplier. Zhuzhou XingYe sent me samples, and the quality was actually better than my previous source. We now order 300 tanks every quarter – their purity testing and DOT stamps make customs clearance smooth every time.”
Sourcing Agent, Oceanic Trade Ltd., UK
“OEM customization was a breeze. I needed a special valve thread (CGA 540) and my own branding on a 10L cylinder. They delivered exactly to spec, with a lead time of 30 days. The MOQ of 100 was perfect for our market test. We’ve already placed two repeat orders.”
Import Manager, Diving Air Solutions, California, USA
“We source thousands of tanks yearly. XingYe’s price-to-quality ratio is outstanding. Their customer service is also top-notch – when we had a small hydrostatic test date discrepancy, they sent a replacement batch via air freight at no extra cost. That kind of support shows they care about long-term relationships.”
CEO, Pacific Diving Supply, Tokyo, Japan
“Compliance with Japanese High Pressure Gas Safety Act is strict. XingYe provided all the needed documentation: material certificates, valve test reports, and ISO 9001. The cylinders passed inspection at Yokohama port without a hitch. They are now our primary oxygen tank supplier for the Asia region.”
