However, the provided information confirms no overseas warehouse, showroom, agent, or branch, and no overseas service-country coverage. Evidence of customer engagement includes products recommended by the World Customs Organization and service to well-known integrators and end customers, but specific customer names or project details are not provided. Financial information is present only as year labels, without assessable financial results.

Supplier typeThe supplier is identified as a combined company and explicitly states that it is not an offshore company. This supports classification as a combined, non-offshore supplier.

CertificationsThe supplier reports an ISO9001:2015 certificate under supplier management systems and sustainable development management system certification. The provided slices do not identify the issuing body, validity period, or scope, but they do explicitly confirm certification holding.

After-Sales capabilityTechnology engineers are responsible for technical support for production and after-sales service, while service capability is supported by written procedures, followed records, and corrective/preventive-action procedures. However, the supplier has no overseas warehouse, showroom, agent, or branch, which limits documented overseas service infrastructure.

Customization capabilityThe supplier explicitly offers customization from samples, designs, minor customization, full customization, and flexible customization, supported by 3D software design services and ODM capability. This indicates broad adaptation to customer-specific requirements.

Client casesThe supplier states that its products have been recommended by the World Customs Organization and that it serves well-known international and domestic large-scale integrators and end customers. It also reports participation in the 6th Global AEO Conference, but no named customer cases, project descriptions, or independently verifiable case details are provided.
