SummaryMingshi is a China-based supplier in Zhejiang with documented manufacturing, customization, quality-control, export, and service capabilities. It offers sample-, design-, and fully customized products, ODM and OEM services, and operates punching, CNC, cutting, and pipe-processing facilities. The supplier has quality, environmental, social-responsibility, product, and regional certifications, while its products are reportedly sold in 38 countries and regions. Service procedures and records exist for corrective actions and customer complaints, but there are no overseas agents, branches, warehouses, showrooms, or stated overseas service countries. Innovation evidence is limited because no new products were reported in the past year and no SDK is available. Financial credibility cannot be assessed from the provided information because the financial entries only identify reporting years without performance figures. The supplier has no valid contract with associated subcontractors and no Fortune 500 customer...

Supplier typeThe supplier is a China-based manufacturer headquartered in Zhejiang, with punching, CNC, cutting, and pipe-processing facilities. Its products are reportedly sold in 38 countries and regions, indicating an export-oriented manufacturing profile.

CertificationsThe supplier reports CE, ISO9001:2015, ISO14001, and BSCI certifications, plus AENOR, SKZ, WaterMark & StandardsMark, and JASWIC certifications. These provide explicit evidence of product, management-system, environmental, social-responsibility, and regional compliance coverage.

After-Sales capabilityThe supplier has clear procedures and followed records for corrective and preventive actions and customer complaints, and its company description claims strong after-sales service. However, it reports no overseas agents or branches, no overseas warehouse or showroom, and zero stated countries offering overseas services.

Production capacityProduction evidence includes punching, CNC, cutting, and pipe-processing facilities, finished-product inspection instructions that are uniformly followed, and in-stock service capability. A material control gap is that no valid contract exists between the factory and associated subcontractors.

Customization capabilityThe supplier explicitly provides customization from samples, customization from designs, and full customization. It also reports ODM availability, directly supporting broad customization and design-manufacturing flexibility.

Client casesThe supplier reports OEM service for well-known brands, sales across 38 countries and regions, and a repeat-buyer preference of 80%–100%. However, it reports no cooperation with Fortune 500 companies, and no specific customer names or verifiable case details are provided.
