About Quzhou Quhua Zhongxing Refrigeration Technology Co., Ltd. - Industrial Chemicals Supplier in China

Quzhou Quhua Zhongxing Refrigeration Technology Co., Ltd. operates from Quzhou, China and currently lists five active products in its catalogue. The company is classified under the imported‑harbor trust tier and is recorded under the industrial chemicals category. All five items are refrigerants that are standardised by ASHRAE designations and are commonly used in commercial and industrial cooling systems. The product list includes R404A, R407C, R22, R134a and R410A, each identified by its conventional trade name without additional proprietary labeling. The supplier’s catalogue does not provide specific HS‑code numbers, but these chemicals are generally classified under HS chapter 28 for organic chemicals.

The five refrigerants cover a range of HCFC, HFC and blended formulations that serve different temperature and pressure requirements. R404A and R407C are zeotropic blends for low‑temperature refrigeration, while R22 is an older HCFC still found in legacy systems. R134a is a single‑component HFC used in automotive and medium‑temperature applications, and R410A is a high‑pressure blend for modern air‑conditioning units. The listing reflects a focused portfolio rather than a broad chemical line, allowing buyers to assess each product’s technical data individually.

Product Range and Specialties of Quzhou Quhua Zhongxing Refrigeration Technology Co., Ltd.

The catalogue offers the following refrigerants: R404A, R407C, R22, R134a and R410A for air‑conditioning replacement. In the wider industry, R404A is supplied with a purity of ≥ 99.5 % and a typical global warming potential (GWP) of 3,922; R407C is offered with similar purity and a GWP of about 1,774. R22, an HCFC, carries an ozone depletion potential (ODP) of 0.05 and is phased out in many regions, so buyers often request compliance documentation. R134a is an HFC with a GWP of roughly 1,300 and is standard for medium‑temperature systems. R410A is a near‑azeotropic HFC blend with a GWP near 2,088 and operates at higher pressures than R22. Common specifications demanded by purchasers include moisture content below 10 ppm, pressure‑temperature performance charts, and verification of leak‑tightness according to ISO 8573‑1. Packaging is typically in aluminium‑lined steel drums of 200 kg or high‑pressure cylinders of 50 kg.

Trade and Export Information - Quzhou Quhua Zhongxing Refrigeration Technology Co., Ltd.

China ranks among the top global exporters of synthetic refrigerants, with shipments routinely directed to Southeast Asia, the Middle East, Eastern Europe and Western Europe. Export logistics usually involve 20‑ft or 40‑ft containers equipped with IATA‑compliant inner drums or cylinders, and the goods are declared under the HS chapter 28 (organic chemicals) for customs processing. Importing parties often require evidence of ISO 9001 quality‑management certification and ISO 14001 environmental compliance, although the supplier’s public record does not list specific certifications. In addition, buyers in the EU must verify conformity with the EU F‑Gas Regulation (Regulation (EU) 517/2014), which limits the use of high‑GWP substances and may require a Phase‑Down schedule. Typical commercial terms include FOB or CIF, with freight handled by major shipping lines that accommodate hazardous‑goods handling procedures.

Sourcing from Quzhou Quhua Zhongxing Refrigeration Technology Co., Ltd. - Buyer Guidance

When sourcing refrigerants from this supplier, buyers should request a current Material Safety Data Sheet (MSDS) and a Certificate of Analysis (CoA) that confirms purity, moisture level and GWP/ODP values for each blend. It is prudent to verify whether the supplier can provide ISO 9001 or ISO 14001 audit reports, as these are standard assurances for industrial chemicals. Buyers should also confirm the packaging format (200 kg drum or 50 kg cylinder), the minimum order quantity - commonly 500 kg per refrigerant type - and the expected lead time, which industry practice places at 30‑45 days from order confirmation. Finally, ensure that the shipment documentation includes the appropriate Dangerous Goods Declaration and that the consignee is prepared for any import licensing related to HCFC or high‑GWP HFC substances.
