AI-Powered supplier vetting
SummaryChina Coal is identified as a combined company with manufacturing, export, service, quality-control, and R&D capabilities. It reports ISO9001:2008, ANAB, UKAS, and SGS-related certifications or credentials, alongside quality-related national and industry honors. The supplier offers customization, ODM, OEM for popular brands, SDK availability, and documented quality and supplier-service procedures. It has 12 quality inspectors, in-stock capability, valid contracts with associated subcontractors, and approximately one-month lead times in both peak and off-season periods. Overseas services include debugging, maintenance, repair, training, and installation in Denmark, Colombia, India, and Georgia. However, it reports no overseas warehouse, showroom, agent, or branch, and the provided evidence does not establish specific customer names or independently verify financial strength.
Supplier typeThe supplier is explicitly classified as a combined company and presents offerings spanning export trade, manufacturing, service, quality control, R&D, and sustainable development. It is also identified as a non-offshore company name, indicating a directly identified operating supplier rather than an offshore entity.
CertificationsThe company description states that China Coal has passed ISO9001:2008, United States ANAB management-system, and United Kingdom UKAS management-system certifications. It also cites SGS certification and several national quality, reputation, conformity-assessment, and credit honors; the slices do not provide certificate numbers, validity dates, or scope details.
After-Sales capabilityThe supplier provides overseas debugging, maintenance, repair, training, and equipment installation in Denmark, Colombia, India, and Georgia, and has participated in an offline trade show. It reports no overseas warehouse, showroom, agent, or branch, so service coverage exists but lacks those overseas facilities and channels.
R&D capabilityThe supplier reports new products during the past year, provides ODM services, and has an available SDK. These statements directly support active R&D and product-development capability, although no R&D staffing, patents, or quantified development results are supplied.
Production capacityProduction-related evidence includes cutting, painting, sawing, and shearing equipment; valid contracts with each associated subcontractor; in-stock capability; 78 qualified service-capability suppliers; and approximately one-month lead times in both off-season and peak season. The supplier also has documented supplier-service procedures and corrective/preventive-action records.
Customization capabilityBoth R&D and design-capability records explicitly list customization from samples, customization from designs, full customization, minor customization, and flexible customization. The supplier therefore demonstrates a broad stated customization range across design and R&D functions.
