AI-Powered supplier vetting

SummaryThe supplier manufactures and sells outdoor, fitness, sports, fishing, yacht, and related products, with import and export capability. It reports OEM service for popular brands, ODM and multiple customization options, new products within the past year, more than 10 production lines in one record, and 21–30 quality-control staff. Service procedures and corrective-action records are documented, and the supplier has participated in GBE 2025. However, it reports no overseas warehouse, showroom, agent, or branch, and lists zero countries with overseas services. Financial records are referenced for 2022–2024, but no financial figures are provided. Innovation evidence is mixed: one national science and technology progress award and recent product development are reported, while no SDK is available. Manufacturing quantity reconciliation is not continuously performed for each batch or volume.

Supplier typeThe supplier is a manufacturer and seller of outdoor products, yachts and accessories, fitness and sports equipment, fishing supplies, and related metal, fiberglass, and mechanical products. Its stated scope also includes sports services and import/export of goods and technology.

After-Sales capabilityThe supplier has written service-capability procedures, followed records, and a corrective/preventive-action mechanism, and it has attended the GBE 2025 offline trade show. However, it reports no overseas warehouse, showroom, agent, or branch, and zero countries with overseas services, limiting evidence of international after-sales coverage.

R&D capabilityThe supplier reports one national science and technology progress award, new products within the past year, ODM capability, and a total R&D engineer experience figure of 3. It does not provide an available SDK, indicating that innovation-related evidence is positive for product development but not sufficient to establish broad technical capability.

Production capacityProduction evidence includes 21–30 quality-control staff, more than 10 production lines in one record, six production lines in another, and reported carbon-fiber output information. However, the supplier states that it does not continuously reconcile quantities for each batch or production volume, which is a documented manufacturing-control weakness.

Customization capabilityThe supplier explicitly offers full, minor, flexible, design-based, and sample-based customization, along with ODM services. This demonstrates broad customization options across both customer designs and samples.

Product Q&A

Q:What is the minimum and maximum diameter and length?

Minimum diameter is 4mm. Maximum outer diameter is 400mm. Maximum length is 6000mm. Larger sizes can be customized upon request.

Q:How long is the delivery time?

Sample orders take 7-10 days with molds or 15 days without. Large orders for standard tubes take about 30 days, while custom items like billiard cues require confirmation.

Q:What are the advantages of your carbon fiber products?

Features include high axial strength, low density, no creep, ultra-high temperature resistance, good fatigue resistance, and excellent corrosion resistance in harsh environments.

Q:How do you control the straightness of the tubes?

We use high precision grinding machines to ensure the straightness is within 0.1mm.

Q:What customization options are available?

We offer full customization including size, shape (square, round, bent, etc.), surface finish (twill, plain, matte), and logo printing via OEM/ODM services.
