About Shiyan Renman Automobile Parts Co., Ltd - Engine Spare Parts Supplier in China

Shiyan Renman Automobile Parts Co., Ltd is based in China and currently lists five distinct engine spare part items in its catalogue. The product portfolio includes a cylinder block (model C3971411), a connecting rod (model 4943979), an oil pump (model C4937405), a water pump (model C3800974) and a piston (model C4987914). All items fall under the engine spare parts category, which is commonly classified under HS Chapter 87 for motor vehicle parts. The supplier is identified as an imported tier with a harbor trust tier in the platform.

The catalogue focuses exclusively on core internal combustion engine components that are typically required for repair, refurbishment or aftermarket replacement. Each listed part is identified by a specific product code, enabling buyers to match OEM specifications. The range does not include ancillary accessories such as filters or sensors, concentrating instead on the primary moving and fluid‑handling elements of an engine.

Product Range and Specialties of Shiyan Renman Automobile Parts Co., Ltd

The five listed components represent the fundamental building blocks of a piston engine. Cylinder blocks are ordinarily produced from grey cast iron or aluminium‑silicon alloys, with typical tolerance grades defined by ISO 9001‑based quality management systems; connecting rods are frequently forged from high‑strength steel grades such as 35CrMo or 42CrMo and may be heat‑treated to achieve tensile strengths of 800‑1000 MPa. Oil pumps and water pumps are generally cast metal units with sealing surfaces machined to ISO 2768 tolerance classes, while pistons are supplied in aluminium alloy grades (e.g., A319) with clearance specifications measured in micrometres. Buyers should compare these material and tolerance standards with the specifications of the target engine model.

Trade and Export Information - Shiyan Renman Automobile Parts Co., Ltd

China is a major exporter of engine spare parts, with shipments typically routed to automotive manufacturers and aftermarket distributors in Europe, North America, Southeast Asia and the Middle East. The HS code family most frequently used for such components is 8708, which covers parts and accessories of motor vehicles. International buyers often require certifications such as ISO 9001 or IATF 16949, along with material test reports and conformity declarations, to satisfy quality‑control procedures in their own markets. Standard export packaging includes wooden crates or reinforced pallets, protected with shrink‑wrap or foam inserts, and shipments are commonly quoted on FOB Shanghai or CIF destination ports, depending on buyer preference.

Sourcing from Shiyan Renman Automobile Parts Co., Ltd - Buyer Guidance

When sourcing these engine components, request a full material test report that specifies alloy composition, hardness and tensile strength for each part. Verify that the dimensions and bore tolerances match the OEM data sheet of the intended engine, and ask for a compliance statement referencing ISO 9001 or IATF 16949 quality systems. Samples of the cylinder block or piston can be ordered to confirm machining accuracy before committing to a larger order, and buyers should confirm packaging details - such as crate dimensions and moisture‑proofing - to prevent damage during sea freight.

Which engine models are the listed parts compatible with?

Compatibility depends on the original equipment manufacturer (OEM) specifications; buyers should provide the engine series, displacement and year to match the cylinder block, connecting rod, oil pump, water pump and piston dimensions.

How can I verify the material composition of the cylinder block?

Request a material test report that lists the cast iron or aluminium‑silicon alloy grade, along with hardness (HB) and any heat‑treatment details. The report should be signed by an accredited laboratory.

Which certifications should I request before purchasing engine spare parts?

Typical certifications include ISO 9001 quality‑management certification and IATF 16949 for automotive‑industry quality systems. Buyers may also ask for a conformity‑of‑production (CoP) declaration.

What are the standard packaging methods for these components?

Engine components are usually packed in wooden crates or reinforced pallets, with each part individually wrapped in protective film or foam to prevent scratches and corrosion. Moisture‑absorbing packets are added for long sea‑transit shipments.

What is the usual lead time for a bulk order of these parts?

Lead times vary by part but generally range from 25 to 45 working days for production and quality inspection, plus additional time for packaging and export clearance.

Which HS codes are commonly applied to engine spare parts exported from China?

The HS code 8708.99 covers miscellaneous parts of motor vehicles, including cylinder blocks, connecting rods, oil pumps, water pumps and pistons. Specific sub‑headings may be used depending on the exact component.

Can I obtain a sample of the piston before placing a full order?

Yes, a single piston sample can be requested for dimensional verification and material testing. Sample shipping is typically arranged on a DAP (Delivered at Place) basis.

Which Incoterms are typically used for shipping these engine components?

Exporters from China often quote FOB Shanghai for buyers who prefer to arrange main carriage, while CIF (Cost, Insurance, Freight) to major ports such as Rotterdam or Los Angeles is also common for turnkey deliveries.
