About Hongtuo Mechanical Casting Co., Ltd - Metal Castings & Forgings Supplier in China

Based in China, Hongtuo Mechanical Casting Co., Ltd lists 12 active products across metal castings and related pump components. The catalogue includes investment‑cast pump bodies in stainless steel grades CF‑8/CF‑8M (AISI 304/316 equivalent) classified under HS 8413.91, double‑volute pump bodies in gray cast iron (FC250) and ductile iron (FCD400) under HS 8481.20, and stainless steel pump covers under HS 8481.90. Additional items cover precision‑cast water pump guide vanes, customized pump impellers, mechanical seals, and cast‑iron sealing casings (HS 7325.10).

The product set spans the top categories of Metal Castings & Forgings, Industrial Pumps, Cast Iron, Pipe Valves and Mechanical Seals. Materials range from stainless steel 304/316 (ASTM A351 CF8/CF8M) to gray and ductile iron, and the listings reference HS code families 8413, 8481 and 7325 that are typical for pump bodies, impellers and cast‑iron components.

Product Range and Specialties of Hongtuo Mechanical Casting Co., Ltd

The catalogue focuses on pump‑related castings: investment‑cast bodies in stainless steel CF‑8/CF‑8M, gray cast iron FC250 and ductile iron FCD400 pump housings, stainless steel pump covers, precision‑cast guide vanes and custom‑shaped impellers, as well as mechanical‑seal wear rings and cast‑iron sealing casings. In the industry, stainless‑steel pump bodies are commonly produced to ASTM A351 with surface roughness Ra ≤1.6 µm and dimensional tolerance ±0.1 mm, while gray‑iron FC250 and ductile‑iron FCD400 are specified for tensile strength 250‑350 MPa and elongation ≥5 %. Typical pump bodies range up to 500 mm in diameter and 300 mm in length, and impellers are often supplied in 150‑250 mm diameter sizes with balanced mass distribution for hydraulic efficiency.

Trade and Export Information - Hongtuo Mechanical Casting Co., Ltd

China is a leading exporter of metal castings, and the HS‑code families 8413 (pumps), 8481 (machinery parts) and 7325 (cast iron) are routinely used for customs clearance of pump bodies, impellers and sealing casings. Major import markets include Europe’s water‑treatment sector, North America’s oil‑and‑gas equipment buyers, and Southeast Asia’s HVAC manufacturers. Buyers typically require ISO 9001 quality‑management certification, ASTM material compliance and, for EU destinations, CE conformity declarations. Standard logistics involve wooden crates or palletized loads inside 20‑ft or 40‑ft containers, with FOB Shanghai or CIF Europe as common Incoterms. Export controls in China mandate accurate HS‑code declaration and inspection of cast‑iron items under the “Export Commodity Inspection” program.

Sourcing from Hongtuo Mechanical Casting Co., Ltd - Buyer Guidance

When sourcing these castings, request a current material test certificate that lists chemical composition and mechanical properties in accordance with ASTM A351 for stainless steel or ASTM C795 for cast iron. Verify that the HS code on the commercial invoice matches the product description (e.g., 8413.91 for stainless‑steel pump bodies) and ask for a third‑party inspection report if large orders are planned. Confirm minimum order quantities - typically one 20‑ft container or a weight‑based MOQ of 500 kg per product - and allow 30‑45 days lead time for tooling, casting and post‑processing before shipment.

What material grades are offered for pump bodies?

The catalogue lists stainless‑steel CF‑8/CF‑8M (equivalent to AISI 304/316) and gray‑cast iron FC250 together with ductile‑iron FCD400, which are standard grades for industrial pump housings.

Which HS codes correspond to the listed products?

Pump bodies in stainless steel fall under HS 8413.91, cast‑iron pump bodies and related parts under HS 8481.20, stainless‑steel pump covers under HS 8481.90, and cast‑iron sealing casings under HS 7325.10.

Does the supplier hold any quality certifications?

A product title mentions ISO 9001, but buyers should request an up‑to‑date ISO 9001 certificate to confirm that the supplier’s quality‑management system meets the standard.

What are typical minimum order quantities?

For cast components, suppliers often set the MOQ at one 20‑ft container (approximately 20 tonnes) or a minimum weight of 500 kg per item, depending on size and material.

What documentation should be obtained before shipment?

Buyers should obtain a material test certificate, a compliance declaration matching the HS code, a packing list with crate dimensions, and for EU shipments a CE Declaration of Conformity where applicable.

How are the pump castings packaged for export?

Items are normally crated in wooden pallets, wrapped with anti‑corrosion film, and loaded into 20‑ft or 40‑ft containers with moisture‑absorbing packs to protect surface finish during transit.
