r123 gas Manufacturers

R123 gas is primarily used as a low-pressure refrigerant in centrifugal chillers and as a cleaning agent in precision electronics. When sourcing, ensure the purity level is ≥99.8% to prevent equipment corrosion. It is characterized by a low Ozone Depletion Potential (ODP) and is often used as a retrofit for R11, though it is subject to phase-out schedules under the Montreal Protocol.

Suppliers must provide an AHRI 700 Standard certificate, which is the global benchmark for refrigerant quality. Additionally, because R123 is a chemical substance, you must verify the SDS (Safety Data Sheet) and ensure the product carries the correct UN Number (UN 2810 or similar depending on concentration) and CAS Number (306-83-2) for customs clearance.

Always request a Gas Chromatography (GC) analysis report from the supplier. For bulk orders, it is highly recommended to perform a pressure-temperature (PT) chart test upon receiving samples. Ensure the cylinders are non-refillable (DOT-39) or refillable (ISO-certified) depending on your local environmental regulations.

R123 is a liquid at room temperature but highly volatile. It must be stored in cool, well-ventilated areas away from direct sunlight and heat sources. Ensure the supplier uses corrosion-resistant steel cylinders or ISO tanks that have undergone hydrostatic pressure testing within the last 5 years.

R123 is classified as Dangerous Goods (DG) for transport. You must ensure the supplier has a License for Export of Dual-Use Items and Technologies (if applicable) and provides a Certificate for Safe Transport of Chemical Goods. Shipping must be handled by specialized DG forwarders, and the containers must be labeled with Class 2.2 non-flammable gas or Class 6.1 toxic labels depending on local maritime laws.

Utilize the Secured Trading services on Made-in-China.com to ensure payment is only released after the goods pass inspection. Conduct a factory audit or hire a third-party inspector (like SGS or Intertek) to verify the filling weight and gas purity before the container is sealed.

Many countries have import quotas for HCFCs (Hydrochlorofluorocarbons) like R123. Before placing an order, confirm that you possess the necessary Import Permits from your local environmental protection agency. Failure to provide these can lead to customs seizure and heavy fines.

Price is heavily influenced by raw material costs (fluorspar) and seasonal demand. To get the best rate, aim for Full Container Load (FCL) orders to reduce the per-unit shipping surcharge for dangerous goods. Ask for a tiered pricing structure where the unit price drops by 5-10% for orders exceeding 10 tons.
