Import managers, wholesalers & brand owners: If you are sourcing a 5 pound noz tank for whipped cream or beverage applications, you need a unit that meets U.S. DOT/UN pressure vessel standards, delivers consistent N2O purity (≥99.9%), and fits your supply chain lead time. This page gives you the technical specs, compliance certificates, MOQ, and OEM/ODM capabilities you need to evaluate Zhuzhou XingYe Chemical as your factory partner — no fluff, only decision-grade data.
Why most 5‑pound Noz tank suppliers cost you time and money
Sourcing a 5 pound noz tank from overseas often comes with three hidden risks: inconsistent gas purity that clogs your filling equipment, missing or incorrect pressure certifications that delay customs clearance in the U.S., and long lead times that kill your inventory turns. Many import managers tell us they have received tanks with dented valves or incomplete paperwork (no COA, no MSDS, no ECM declaration). That is why we built our entire production line around repeatable quality, full documentation, and a lead time that works for your P&L.
- Uncertified tanks rejected at US ports
- Gas purity below 99.9% causes off‑flavors
- Minimum orders that force overstock
- DOT/UN approved cylinders + full COA/MSDS
- N2O purity ≥ 99.9% (GC tested every batch)
- MOQ from 500 pcs, flexible mixing options

Compliance that clears customs – every time

- Certificate of Analysis (COA) – batch‑specific purity and pressure data
- Material Safety Data Sheet (MSDS) – conforms to OSHA Hazard Communication Standard (29 CFR 1910.1200)
- ECM Declaration of Conformity – for European re‑exports if needed
- Food‑grade gas certificate – N₂O meets FDA 21 CFR 184.1545 for use as a propellant in whipped cream

We also provide ISO 9001:2015 certification for your supplier audit file.

Where the 5 pound Noz tank fits your business

What import managers & brand owners say
Mike DelgadoOwner, Delgado Imports (California)
"We tested 5 lb tanks from three suppliers. XingYe’s gas purity was noticeably better — no residue in our dispenser valves. The DOT stamp saved us two weeks of customs paperwork. Now our standard SKU."
Sarah LinSourcing Manager, Wholesale Cream Supply (Texas)
"OEM process was smooth. We sent our artwork, and within 10 days we had pre‑production photos. The final batch arrived with matching labels and shrink sleeves — no quality dips. MOQ of 500 worked for our pilot."
James O’BrienProcurement Lead, BakeSupply Inc. (Florida)
"We ship to 12 US states, so consistency matters. Over 8 months, three 5‑lb tank orders all had the same fill weight and pressure. Their COA data is accurate. We just renewed a 12‑month contract."
David TorresCo‑owner, NYC Artisan Cream
"I was skeptical about Chinese supply chain until I visited their factory. The filling line is clean, they have real QC lab, and they actually answer emails on weekends. Our 5 lb tanks sell out every month."

Every spec, certification, and process described here has been verified during my factory audits (2022, 2024). I personally reviewed the batch records and customs clearance documents for the 5 lb noz tank line.
