AI-Powered supplier vetting

SummaryGuangzhou Shuangcheng Auto Parts Co., Ltd. is identified as a China-based manufacturer/factory and private limited company supplying piston rings and other engine components. It reports 10 production lines, 11–20 quality-control staff, annual piston-ring output of 10,000,000 sets, and lead time within 15 workdays during off-peak seasons. The supplier offers multiple customization modes, has reported new products during the past year, and provides ODM services. ISO 9000, ISO 9001, and ISO 20000 certifications are listed, while an SGS audit record is valid from April 16, 2026 to April 15, 2027. The supplier states a three-year or 100,000 KM warranty and offers neutral or customized packaging. Financial records are indicated for several years, but the slices do not provide sufficient performance details to assess credibility. No customer names, brand OEM cases, or documented customer projects are provided.

CertificationsThe supplier lists ISO 9000, ISO 9001, and ISO 20000 certifications. An SGS audit record is also provided with a validity period from April 16, 2026 through April 15, 2027, but the audit result is shown only as code “0,” without an explanatory assessment.

After-Sales capabilityThe company description states a three-year or 100,000 KM warranty and invites customers to request service, advice, clarification, and additional product information. This is explicit evidence of a stated warranty and service-support commitment.

R&D capabilityThe supplier reports new products within the past year, provides ODM services, and has 6–10 years of total R&D-engineer experience. However, it reports no available SDK and no OEM service for popular brands; overall innovation capability is supported, but not comprehensively demonstrated across all technical-development areas.

Production capacityThe supplier reports 10 production lines, 11–20 quality-control staff, and annual piston-ring output of 10,000,000 sets, with products including piston rings, pistons, cylinder liners, and engine bearings. It also reports exports to multiple regions and off-peak lead time within 15 workdays, providing explicit evidence of operational capacity.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, and flexible customization. It also offers neutral or customized packaging, indicating customization coverage for both products and packaging.
