AI-Powered supplier vetting

SummaryThe supplier is identified as a trading company focused on import/export agency, machinery, hardware, and metal-chain products. It reports substantial listed output for rollers, chains, bolts, nuts, and idlers, but finished products are checked by packing staff, and no quality assurance evidence is provided. Service governance is weak: no written procedures or records are reported for service assessment, corrective actions, or complaint handling, and there are no overseas warehouses, showrooms, agents, branches, or offline trade-show participation. Export-related information is mixed, with 90% of sales reportedly from exports, while another field lists the primary export market as domestic. Design support is limited to minor customization, with one R&D engineer and no ODM, notable-brand OEM, or SDK capability. Financial fields contain zero values and incomplete period information, but monetary figures are excluded here; therefore financial credibility cannot be positively established. No certification or...

Supplier typeThe supplier is explicitly classified as a Trading Company. Its stated scope covers import/export agency, domestic trade agency, machinery and construction-equipment sales, and hardware and metal-chain products, indicating a trading-oriented rather than clearly manufacturing-oriented business model.

After-Sales capabilityThe supplier reports no written procedures or records for service assessment, corrective and preventive actions, or customer-complaint handling. It also has no overseas warehouse, showroom, overseas agent or branch, and no reported offline trade-show participation; these facts indicate limited documented and overseas service infrastructure.

R&D capabilityThe supplier has one R&D engineer and reports no ODM service, no OEM capability for popular brands, and no available SDK. Its design capability is limited to minor customization, providing explicit evidence of constrained innovation and development capability.

Production capacityThe supplier lists annual quantities of 250,000 carrier rollers, 200,000 track rollers, 50,000 idlers, 10,000 track chains, and 3,800,000 bolts and nuts, with lead times within 15 working days in both peak and off-season. However, finished products are checked by packing staff, and the supplier is classified as a trading company; the output information supports product supply capability but does not establish strong manufacturing or quality capability.

Customization capabilityThe supplier explicitly reports minor customization capability. It does not provide ODM services or OEM services for popular brands, so customization is available only at a limited level rather than as a broad design or branded-development service.

Product Q&A

Q:Are you a trading company or a manufacturer?

We operate a 'Manufacturer +' model. We are the direct manufacturer of Fasteners (via our 25-year family-owned factory) and strategic equity partners for Undercarriage Parts. You get factory-direct prices with professional export service.

Q:How do you guarantee product quality?

Quality is our first priority. We use premium 40Cr/35CrMo steel with precise heat-treatment. Every batch undergoes strict inspections (hardness, dimensions, visual) before leaving our Changsha/Quanzhou warehouses. Material certs and warranties are provided.

Q:How can I ensure the parts fit my machine?

It's easy! Simply provide the machine model, part number, or serial number. For non-standard parts, just send us the dimensions or drawings.

Q:What are your delivery time and MOQ?

Thanks to our dual warehouses (Changsha & Quanzhou), we offer flexible support: Delivery: 3-7 days for in-stock items; 20-30 days for mass production. MOQ: Highly flexible. Usually 100-500 pcs for bolts, and 10-20 pcs for undercarriage parts. Tip: Mixing parts in one pallet is recommended to save shipping costs.

Q:How is the packaging?

We ensure 100% safe arrival. All goods are packed with export-standard heavy-duty protection. We prioritize waterproof sealing and robust palletizing to strictly prevent rust and damage during long-distance sea shipping.
