R123 refrigerant

R123 (Dichlorotrifluoroethane) is a HCFC refrigerant primarily used in low-pressure centrifugal chillers for commercial and industrial air conditioning systems. It is highly valued for its high thermodynamic efficiency and low operating pressure. When sourcing, ensure the purity level is ≥99.8% and moisture content is ≤10ppm to prevent system corrosion and maintain cooling performance.

As an HCFC, R123 is subject to the Montreal Protocol phase-out schedule. Buyers must verify that the product meets AHRI 700 standards for refrigerant quality. It is essential to check local environmental regulations, as many countries have strict import quotas or specific bans on HCFCs. Ensure the supplier provides a Certificate of Analysis (COA) and a Material Safety Data Sheet (MSDS).

Prioritize suppliers who use refillable steel cylinders that comply with international pressure vessel standards like DOT-39 or CE/EN13322. Conduct acidity tests (target <1ppm) to ensure the chemical won't damage compressor windings. For large-scale B2B orders, it is recommended to use third-party inspection services (such as SGS or Intertek) to verify the net weight and chemical composition before shipment.

R123 is classified as Class 2.2 Non-flammable Gas (or Class 6.1 depending on concentration/local laws) for transport. It must be shipped via specialized hazardous goods (DG) containers. Ensure the supplier is experienced in IMO Class 2 maritime logistics and provides correct UN Number labeling (UN 2811 or similar) to avoid customs seizures or heavy fines at the port of entry.

Utilize secure payment methods and look for Audited Suppliers on professional platforms like Made-in-China.com, which verifies the manufacturer's production capacity and business license. Always negotiate a Trade Assurance agreement that covers quality discrepancies. Avoid suppliers who cannot provide a Gas Export License, as this is a mandatory legal requirement for exporting refrigerants from China.

Refrigerant prices are highly sensitive to raw material costs (fluorspar) and environmental tax policies. To optimize costs, consider bulk purchasing in ISO Tanks rather than small cylinders to reduce the unit price by 15-20%. Request a price breakdown including the cost of the cylinder (deposit vs. purchase) and clarify Incoterms (FOB vs. CIF) to manage volatile ocean freight rates for hazardous materials.
