freon gas r404a price Manufacturers

Buyers must ensure the purity level is at least 99.8% to prevent compressor damage. Key parameters include moisture content (≤10ppm), acidity (≤1ppm), and non-condensable gas volume (≤1.5%). Always request a Certificate of Analysis (COA) for every batch to confirm the chemical composition of the HFC blend (R125/R143a/R134a).

The product must meet AHRI-700 standards for refrigerant purity. Since R404A is a fluorinated gas, it is subject to the Montreal Protocol and regional regulations like EU F-Gas Regulation or U.S. EPA Section 608. Ensure the supplier provides SDS (Safety Data Sheets) and that cylinders are DOT-certified (USA) or CE/TPED-certified (Europe) for pressure safety.

For maintenance and small-scale repairs, 10.9kg (24lb) or 11.3kg disposable cylinders are standard. For large-scale industrial refrigeration or cold chain logistics, 926L ton tanks or ISO tanks are more cost-effective. Ensure the valve type (e.g., QF-2) is compatible with your local charging equipment.

R404A is a non-flammable liquefied gas under high pressure. It must be stored in a cool, well-ventilated area below 50°C, away from direct sunlight and heat sources. Because it has a high Global Warming Potential (GWP), leak detection systems and proper recovery protocols are essential for environmental compliance.

R404A is classified as Class 2.2 Non-flammable Gas (UN3337). It requires specialized DG (Dangerous Goods) packaging and labeling. You must use a freight forwarder experienced in IMO Class 2.2 shipments. Ensure the supplier provides a Dangerous Goods Declaration and a Container Packing Certificate to avoid port rejection.

The price of R404A is highly sensitive to raw material costs (fluorspar) and quota policies. To lock in prices, consider long-term supply contracts or purchasing during the off-season (Q4). On Made-in-China.com, you can compare multiple verified manufacturers to find competitive FOB prices and evaluate their production capacity.

Focus on volume-based discounts; orders exceeding one 20ft container (approx. 1,150 cylinders) usually trigger significant price breaks. Negotiate for customized branding (OEM) on cylinders if you are a distributor. Always clarify if the quoted price includes the cylinder cost or if they are returnable (though for cross-border, they are typically sold as non-refillable).

Use secure payment terms such as Letter of Credit (L/C) or trade escrow services. Conduct a pre-shipment inspection via third parties like SGS or Intertek to verify cylinder pressure and net weight. On Made-in-China.com, prioritize Audited Suppliers who have undergone on-site factory verification to ensure they have the legal right to export refrigerants.
