About Qingdao Hongtai Metal Co., Ltd. - Air Conditioner Parts Supplier in China

Qingdao, China based Qingdao Hongtai Metal Co., Ltd. lists five active products in its catalogue, all classified under Air Conditioner Parts. The catalogue entries are Insulated copper coil, LWC copper coil, Copper pancake coil, ACR straight tube and Copper capillary coil. Each item is described using its functional name without additional specifications, and the supplier groups them under the broader HS‑74 copper products family commonly used in HVAC equipment.

The five products represent typical components of split‑type and central air‑conditioning systems, where copper is the standard material for heat‑exchange tubing. The insulated coil is used for refrigerant flow with thermal protection, the LWC (low‑water‑content) coil for lightweight applications, the pancake coil for compact heat exchangers, the straight tube for refrigerant lines, and the capillary coil for metering devices. No further details such as dimensions or pressure ratings are provided in the source data.

Product Range and Specialties of Qingdao Hongtai Metal Co., Ltd.

The supplier’s catalogue covers five copper‑based coil and tube types that are essential for air‑conditioning heat exchangers. In the HVAC industry copper coils are typically produced from electrolytic copper with a purity of 99.9 % or higher, annealed to achieve a tensile strength of 210‑260 MPa and a ductility of at least 30 %. Insulated coils often carry a thermal insulation layer of polyurethane or phenolic foam with a thickness of 5‑15 mm, while capillary coils are drawn to diameters of 0.5‑1.2 mm for precise refrigerant metering.

Industry standards for these components include IEC 60335‑2‑40 for air‑conditioner safety, ASHRAE 15 for refrigerant piping, and ISO 9001 quality‑management certification for manufacturers. Buyers normally look for compliance with RoHS (restricting hazardous substances) and CE marking when importing into the EU, as well as test reports confirming pressure resistance (typically 2‑3 MPa for coils) and thermal conductivity values.

Trade and Export Information - Qingdao Hongtai Metal Co., Ltd.

China is a major exporter of HVAC components, and copper coils from the region are shipped to Southeast Asia, the Middle East, Europe and North America. The relevant customs classification generally falls under Chapter 74 (copper and copper products), with sub‑headings such as 7419.89 for copper tubes and 7419.90 for other copper articles. Importers frequently require certificates of origin, material test reports, and conformity to RoHS and CE directives before customs clearance.

Typical logistics involve containerised loads in 20‑ft or 40‑ft containers, with coils and tubes packed in wooden crates or steel pallets to prevent deformation. Incoterms most often used are FOB Qingdao or CIF destination port, allowing buyers to manage freight and insurance according to their preferences. Export documentation usually includes a commercial invoice, packing list, bill of lading, and, where applicable, a test certificate issued by an accredited laboratory.

Sourcing from Qingdao Hongtai Metal Co., Ltd. - Buyer Guidance

When sourcing copper coils from this supplier, request a mill test certificate that specifies copper purity, annealing condition, tensile strength and dimensional tolerances. Ask for a product data sheet that outlines the coil’s insulation thickness, pressure rating and compatible refrigerants (e.g., R‑410A, R‑22). Verify that the supplier can provide RoHS compliance statements and, if required by the buyer’s market, CE conformity documentation.

Confirm packaging details - wooden crates with internal bracing are standard for preventing coil distortion during sea freight. Inquire about minimum order quantities, which for custom‑cut coils often start at one full container load, and typical lead times, which range from 30 to 45 days after final drawing approval. Request a pre‑shipment sample if possible to validate dimensions and material properties before committing to a larger order.
