AI-Powered supplier vetting

SummaryLianyungang Highborn Technology Co., Ltd. is identified as a Chinese manufacturer/factory and limited company in Lianyungang, Jiangsu. It reports broad customization and OEM/ODM capabilities, documented inspection, service assessment, corrective-action, and complaint-handling procedures, as well as 15 years of export experience and exports representing 71%–90% of sales. Production information includes two production lines, 6–10 quality-control staff, and stated output across ceramic and quartz-related products. However, the supplier reports no overseas warehouse, showroom, agents or branches, or offline trade-show participation. Innovation evidence is limited because no new products were reported in the past year and no SDK is available. No certification holdings or customer case details are provided.

After-Sales capabilityThe supplier has written procedures and records for assessing service capability, corrective and preventive actions, and handling customer complaints. However, it reports no overseas warehouse, showroom, agents or branches, and no offline trade-show participation, indicating documented service processes but limited overseas service infrastructure.

R&D capabilityThe supplier offers ODM services and extensive design-based customization, but reports no new products in the past year and no available SDK. This provides evidence of design support but also a stated lack of recent product development.
