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.

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.
