About China Lutong Parts Plant - Engine Spare Parts Supplier in China

China Lutong Parts Plant is based in China and lists 50 active products across its catalogue. The company’s catalogue focuses on diesel engine components such as head rotors, diesel injection valves, fuel plunger assemblies, nozzle assemblies, and complete common‑rail injector systems. Product titles reference specific OEM‑type parts, for example “P Type Dsla 145 P 681 Fuel Injector Nozzles” and “Control Valve 32f61‑00062 For 320d C6 Injector”. The listings also include generic descriptors like “Diesel engine spare parts” and “Machined components”, indicating a breadth of machined diesel‑fuel‑system items.

The catalogue entries are grouped under broader categories that include Nozzle, Engine Spare Parts, Industrial Valves & Gauges, and Light & Medium Machinery. Although the facts do not provide HS codes, the product family falls within the typical HS chapter 84 (machinery and mechanical appliances) and chapter 85 (electrical machinery) ranges used for engine and fuel‑system parts. The supplier’s product set therefore covers both primary fuel‑delivery components and auxiliary control valves used in diesel engines for automotive and agricultural machinery.

Product Range and Specialties of China Lutong Parts Plant

The listed items cover core diesel‑fuel‑system parts: injector nozzles, plunger assemblies, head rotors, common‑rail control valves, and delivery valves. In the diesel‑injection market, nozzle grades are often defined by spray‑hole diameter (e.g., 0.15 mm to 0.30 mm) and flow rate measured in cc/min at a standard pressure of 1,600 bar. Plunger assemblies are typically forged steel with surface hardness of 45‑55 HRC and tolerance of ±0.02 mm on rod diameter. Head rotors and control valves are machined to ISO 9001‑compatible tolerances and may be supplied in powder‑coated or zinc‑plated finishes for corrosion resistance.

Industry practice for these components includes material certifications (e.g., DIN 1629 for injector nozzles, ASTM A681 for high‑strength steel) and testing such as fuel‑spray pattern analysis, leak‑proof pressure testing, and dimensional inspection with CMM equipment. Buyers often request batch‑level test reports that specify flow rate, needle lift, and endurance life cycles (typically 200,000 injection cycles).

Trade and Export Information - China Lutong Parts Plant

China is a major exporter of diesel engine spare parts, supplying aftermarket and OEM markets in Southeast Asia, Europe, and South America. Common‑rail injector assemblies and associated valves are usually classified under HS codes 8421.99 (other parts of machinery) and 8424.99 (other parts of hydraulic, pneumatic or other fluid power systems). Export shipments from China frequently use 20‑foot or 40‑foot containers with wooden pallets, and Incoterms such as FOB Shanghai or CIF Rotterdam are standard for bulk orders.

Buyers importing these components generally require compliance with ISO 9001 quality management systems and may request conformity with SAE J1349 (diesel fuel injector performance) or EN 12427 (engine parts). Inspection agencies often perform pre‑shipment checks for material certification, dimensional accuracy, and functional testing. Export documentation typically includes a commercial invoice, packing list, certificate of origin, and where required, a CE Declaration of Conformity for EU destinations.

Sourcing from China Lutong Parts Plant - Buyer Guidance

When sourcing diesel injection parts from China Lutong Parts Plant, buyers should request material certificates (e.g., steel grade certificates) and recent functional test reports that confirm flow rate, spray pattern, and pressure tolerance. Samples of critical items such as injector nozzles or plunger assemblies should be inspected for dimensional compliance using micrometer or CMM data before full‑scale orders. Verify that the supplier can provide ISO 9001 certification and, if the destination market requires it, SAE or EN test reports specific to the part type.

It is advisable to confirm packaging details - typically double‑wall corrugated boxes with internal foam inserts - and container loading plans to ensure that sensitive injector components are protected from vibration and moisture. Ask for the HS code the supplier will use for customs clearance and confirm that the documentation includes a certificate of origin and, where applicable, a CE or other regulatory declaration.

What diesel injection components does China Lutong Parts Plant list in its catalogue?

The catalogue includes head rotors, injector nozzles (e.g., P Type Dsla 145), plunger assemblies, common‑rail control valves, delivery valves, and complete injector units for various diesel engine models.

Are there any certifications mentioned for the supplier’s products?

The supplied facts do not list any certifications. Buyers should request the supplier’s ISO 9001 certificate and any SAE or EN test reports that are typical for diesel fuel‑system parts.

Which HS code families are relevant for these diesel engine spare parts?

Typical HS code families for these items are 8421.99 (other parts of machinery) and 8424.99 (other parts of hydraulic, pneumatic or fluid power systems), which are commonly used for injector and valve components.

What specifications should a buyer verify for injector nozzles?

Key specifications include spray‑hole diameter, flow rate at 1,600 bar, material grade (often high‑strength steel per DIN 1629), and hardness in the range of 45‑55 HRC. Dimensional tolerance is usually ±0.02 mm.

What documentation is typically required before shipment?

Buyers usually request a commercial invoice, packing list, certificate of origin, material certificates, recent functional test reports, and, for EU markets, a CE Declaration of Conformity.

What are the common packaging and shipping methods for these parts?

Parts are generally packed in double‑wall corrugated boxes with foam inserts, placed on wooden pallets, and shipped in 20‑ft or 40‑ft containers under Incoterms such as FOB Shanghai or CIF Rotterdam.

What lead times and minimum order quantities are typical for diesel injection parts?

Lead times often range from 30 to 60 days depending on part complexity, and minimum order quantities can vary from a single set of injectors to several hundred pieces for bulk components such as nozzles or plungers.

How can a buyer ensure quality compliance for these components?

Request ISO 9001 certification, recent SAE J1349 or EN 12427 test reports, and conduct pre‑shipment dimensional inspections. Verifying material certificates and functional test data helps confirm compliance with industry standards.
