If you are sourcing 3kg gas cylinder suppliers for your business — whether for LPG, nitrous oxide, carbon dioxide, or specialty gas storage — you need a partner that guarantees consistent quality, compliance with international standards, and flexible supply options. At Zhuzhou XingYe Chemical (China), we have supplied 3kg gas cylinders to import managers and wholesalers across the USA and Europe since 2013. Our cylinders meet ISO 9001, DOT, CE, and ECM requirements, and we support OEM/ODM branding, custom valve configurations, and fast FOB delivery. This page gives you all the technical and commercial data you need to evaluate us as your next 3kg gas cylinder supplier.
Why Many Buyers Struggle with 3kg Cylinder Procurement — and How We Solve It
-
✓
Pain point: Inconsistent cylinder weight & wall thickness.
We use premium-grade steel (34CrMo4 / 37Mn) from certified Chinese mills. Every batch is hydrostatically tested at 1.5x working pressure. -
✓
Pain point: Long lead times and unclear logistics.
Our factory in Hunan runs 3 production lines dedicated to small-sized cylinders (2–10kg). Standard lead time is 20–28 days after deposit, and we ship via FOB Shenzhen / Ningbo. -
✓
Pain point: Certification confusion for US/EU markets.
Our 3kg cylinders carry DOT (USA), CE/PED (EU), ISO 9809, and ECM (food-grade) certifications. We provide full COA, MSDS, and traceable batch numbers. -
✓
Pain point: Minimum order quantities (MOQ) that choke small brands.
Unlike many suppliers who demand 1000+ units, we offer MoQ as low as 200 pcs for first-time orders, rising to 500 pcs for repeat business.
Summary: We are a 3kg gas cylinder supplier that combines Chinese manufacturing scale with USA/Europe compliance — solving the most common procurement pain points without inflated MOQs or hidden fees.

Every cylinder shipped from our factory includes a complete certification package: batch-specific COA, MSDS (in English), and a test certificate signed by our quality manager. For US-bound orders, we ensure DOT-3AA stamping is visible on the cylinder shoulder. For EU clients, CE / PED marked cylinders with EC type-examination certificate. This means your 3kg gas cylinder is ready for market without re-testing delays.

What Import Managers & Brand Owners Say About Us
James R. — Beverage Equipment Importer, Texas, USA ★★★★★
"We source 3kg CO₂ cylinders for our café distribution network. XingYe's quality is consistent — every batch has the same tare weight and clean paint finish. The DOT stamping saved us weeks of re-inspection. Lead time was 24 days exactly as quoted."
Michael P. — Wholesale Gas Distributor, Manchester, UK ★★★★★
"We were looking for a 3kg gas cylinder supplier who could handle mixed pallets with different valve connections. XingYe made it easy — the OEM process was smooth, and the paperwork (CE + COA) arrived before the container. We've done three repeat orders."
Sarah Lin — Brand Owner (Custom N₂O), Ontario, Canada ★★★★☆
"We needed a custom color and logo on 3kg N₂O cylinders for the Canadian catering market. The team provided Pantone match samples before production. The cylinders arrived in perfect condition — no scratches, no denting. Very professional."
David K. — Sourcing Agent for EU Gas Group, Netherlands ★★★★★
"I've visited the factory personally. The testing lab and production organization are above average for Chinese gas cylinder makers. Their 3kg cylinder pricing is competitive, but I value their consistent MOQ flexibility and valve calibration service."
