Buyer Guides (Q&A)

• Which Chinese Standard Governs Which Step: Cylinder Filling, Marking, Storage and Road Transport (2026)

  The Chinese standards that a refrigerant cylinder actually lives under — filling (GB/T 14193.1-2025, GB/T 34526-2017), cylinder construction (GB/T 5100-2020, GB/T 5099.1-2017), markings (GB/T 7144-2016, GB/T 16804-2011), classification (GB 6944-2025, GB 12268-2025), warehousing (GB 15603-2022) and road transport (GB 13392-2023) — with the status and effective date of each, and the one field to check in each.

• Which Standard Governs Each Step of a Refrigerant Cylinder? — One-Page Map

  One table mapping the life of a refrigerant cylinder — shell, valve, valve outlet, fill limit, inspection, transport and storage — to the framework that governs each step.

• What Happens When a Refrigerant Cylinder Is Filled — And the Records That Let a Buyer Trace It (TSG 23 / GB)

  A fill is a sequence of go/no-go checks, not a single action — and each check is meant to leave a record behind.

• Moving Refrigerant Cylinders by Road in China: The Document Set That Travels With the Load (JT/T 617 / GB 12268-2025)

  Two document sets travel with a road load of refrigerant cylinders — the consignor's and the carrier's. Which party owns which document, and what has to match what.

• Warehouse Discipline for Packaged Refrigerants: Separation Rules, Stacking and the Records That Trace a Cylinder Back to Its Lot (GB 15603)

  An auditor judges a refrigerant warehouse on three separate layers — separation, stacking and records. The third is the one most sites cannot show on the day.

• Storing Refrigerant Cylinders: Segregation, Temperature Limits and Full/Empty Rules (IMDG/ADR/49 CFR)

  Three independent rules govern cylinder storage — what may sit next to what, the 52 °C / 125 °F storage ceiling, and why an "empty" cylinder is not empty. Answers, tables and a specification template.

• Refrigerant Cylinder Retest & Requalification (DOT/ISO/GB): What the Stamped Date Actually Requires

  A cylinder is not a container you keep. It is a pressure vessel with an expiry, and the expiry is stamped on it.

• Receiving a Refrigerant Delivery: Net-Weight Verification and Pre-Unloading Checks (49 CFR/IMDG/CISG)

  You cannot count your way to the right quantity in a refrigerant delivery. Two cylinders with the same product can differ in tare weight, so quantity is verified by.

• Refrigerant Cylinder Filling Ratios & Temperature Compensation (DOT/ISO/GB)

  Why a cylinder is never filled to 100%, and how the fill limit is actually calculated.

• Refrigerant Cylinder Valve Outlets by Market (CGA/DIN/BS/AS) — Why the Same Gas Has Different Connections

  Why the same refrigerant arrives with a different connection in different countries — and what that means for a shipment.
