AI-Powered supplier vetting

SummaryEXCT is a Chinese industrial equipment supplier focused on bulk-material crushing, screening, conveying, and EPC systems. It reports export activity to 70 countries and regions, self-operated import/export rights, CE certification, and substantial stated production capacity across several equipment categories. The supplier offers extensive customization, ODM, and OEM services, but reports no 3D software design, no new products in the past year, and only one R&D engineer. Overseas operational support is limited: it reports no overseas agents, branches, warehouses, showrooms, or offline trade-show participation. After-sales process maturity is not demonstrated because complaint-handling and corrective-action procedures or records are absent. Financial records are indicated for 2022–2024, but their quality and results are not provided.

Supplier typeEXCT is identified as Henan Excellent Machinery Co., Ltd., an EPC-oriented industrial equipment supplier covering bulk-material crushing, screening, conveying, design, production, integration, logistics, and project implementation. Its listed products include vibrating screens, belt conveyors, bucket elevators, apron feeders, mineral sizers, screw and chain conveyors, conveyor idlers, and covers.

CertificationsThe supplier reports CE certification for product compliance and sustainable development/product certification capability. No additional certifications or details on the scope and validity of the CE certification are provided.

After-Sales capabilityThe supplier states a global service concept and reports supplying 70 countries and regions, but it has no overseas agents or branches, warehouses, or showrooms. It also has no written procedures or records for corrective and preventive actions or customer complaint handling, so formal after-sales process capability is weakly evidenced.

R&D capabilityThe supplier offers ODM services and reports customization-related R&D services, but it has only one R&D engineer, no available SDK, no 3D software design service, and no new products launched in the past year. These explicit limitations indicate weak recent product innovation evidence.

Production capacityStated annual capacity includes 600 vibrating screens, 5,000 tons of belt conveyors, 200 bucket elevators, 200 apron feeders, and 200,000 conveyor idlers. The supplier also reports self-operated import/export rights, supporting its ability to manufacture and export these equipment categories.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, flexible customization, and ODM services. It also reports OEM service for popular brands, providing strong evidence of broad customization and contract-manufacturing capability.

Client casesThe supplier reports serving 70 countries and regions and providing OEM services for popular brands, while repeat buyers account for 30%–50%. However, it reports no cooperation with Fortune 500 companies and provides no named customer case details or project references.
