FAQ
What are your delivery times and shipping methods?
We offer flexible delivery times and multiple shipping methods to meet your schedule and budget.
Standard delivery times: For in-stock items, orders are processed and shipped within 15-25 working days from deposit confirmation. This includes order processing, quality inspection, packaging, and booking of shipping space. Custom or non-stock items require 30-45 working days for production and QC.
Expedited options: For urgent orders, we offer expedited processing with air freight delivery in 5-10 working days. A 15% expedite fee applies, subject to stock availability. Express delivery (DHL, FedEx, UPS) is available for sample orders and small batches, delivering in 3-7 days.
Shipping methods: We ship from Tianjin Port via four methods: Sea Freight (most economical for bulk orders, 25-40 days transit), Air Freight (5-10 days, for urgent or high-value parts), Express Courier (3-7 days, for samples and small orders), and Land Transport (rail/truck for Central Asian and Russian markets).
Order tracking: You receive a tracking number within 48 hours of dispatch. For sea freight, we provide the Bill of Lading number and vessel tracking. For air freight, the airway bill number allows real-time tracking. Complete shipping documents (BL, Commercial Invoice, Packing List, Certificate of Origin) are sent by email within 48 hours of departure.
Shipping terms: We support EXW, FOB Tianjin, CFR, CIF, and DDP terms. Your proforma invoice will clearly state the chosen term and all associated costs with no hidden charges.
Do you supply OEM-quality parts for Cummins engines?
Yes, we specialize in supplying OEM-quality replacement parts for Cummins engines, including the ISF2.8, ISF3.8, ISF4.5, and other popular series used in Foton light trucks and commercial vehicles.
What does OEM-quality mean? Our parts are manufactured to the same dimensional specifications, material standards, and performance requirements as the original equipment parts. We use the same cast iron grades, heat treatment processes, and machining tolerances as OEM suppliers. Every critical dimension is verified with calibrated measuring equipment before shipment.
Quality verification: Each batch undergoes three inspection stages: incoming material check (chemical composition, hardness), in-process dimensional inspection (CNC coordinate measuring), and pre-shipment final inspection (surface finish, assembly fit, pressure testing where applicable). Material Test Certificates (MTC) are available on request.
Traceability: Every part carries a part number and batch code, allowing full traceability from raw material to finished product. We maintain records of all inspections and can provide quality documentation for your internal quality systems.
Compatibility guarantee: If a part does not fit the specified engine model due to our error, we will replace it free of charge. We recommend providing your engine model and original part number when ordering to ensure perfect compatibility.
What is the warranty period and how do you handle after-sales issues?
We stand behind every product we sell with a clear warranty policy and responsive after-sales support.
Warranty period: All engine components come with a 6-month warranty from the date of installation, covering manufacturing defects in materials and workmanship. Wear items (filters, brake pads, seals) are covered for 3 months. Electrical components (starters, alternators) carry a 12-month warranty.
How to make a claim: If you encounter a quality issue, contact your assigned sales engineer with the following information: part number, batch code (from packaging label), photos of the defective part, and a brief description of the failure. Our QC team will review the claim within 48 hours.
Resolution options: For confirmed manufacturing defects, we offer free replacement parts shipped with your next order, or a credit note toward future purchases. In urgent cases, we can ship replacement parts via express delivery. We do not require return of defective parts for claims under $500; for higher-value claims, we may request return shipment at our cost.
Technical support: Beyond warranty claims, our engineering team provides free technical support including installation guidance, torque specifications, cross-reference lookup, and troubleshooting. Response time is within 12 business hours via email, WhatsApp, or WeChat.
What is the minimum order quantity (MOQ) for your engine parts?
Our minimum order quantity (MOQ) is flexible and designed to accommodate both new customers testing our quality and established buyers placing bulk orders.
For stock items: Most standard engine parts (filters, bearings, seals, gaskets) can be ordered from as little as 1 piece, allowing you to test fitment and quality before committing to larger quantities. Popular items like cylinder heads, crankshafts, and turbochargers have a minimum of 1 piece for trial orders.
For custom and OEM orders: Private label packaging, custom part marking, and non-stock specifications require a minimum of 100 pieces per SKU. This threshold covers setup costs for custom tooling and packaging production.
Bulk pricing: We offer tiered pricing discounts for orders of 10+, 50+, and 100+ pieces. The more you order, the lower the unit price. Our sales team will provide a detailed quotation with volume discounts within 12 hours of receiving your part number list.
We encourage first-time customers to start with a small trial order to verify quality, fitment, and our service before scaling up. Contact us with your specific part numbers and quantities for an exact MOQ and price quotation.
