AI-Powered supplier vetting
SummaryZhejiang L&B Machinery Co., Ltd. is a China-based factory established in 2002, with 56 employees and a 3,295 m² manufacturing plant. Its product scope includes tanks, emulsifying machines, pumps, valves, mills, storage tanks, and sanitary fittings. The supplier reports ISO 9001:2015 certification, two production lines, export sales of 71%–90%, and export markets spanning Southeast Asia, the Middle East, Europe, and North America. It states one-month lead times in both peak and off-peak seasons and has self-operated import/export rights. Evidence confirms relevant manufacturing and export activity, but information is insufficient to establish after-sales capability, customization capability, or strong innovation performance. Trade records identify one buyer and several stainless-steel valve transactions, supporting evidence of customer activity but not a broad customer portfolio.
Supplier typeThe supplier is identified as a factory and a limited company located in Wenzhou, Zhejiang, China, with company type listed as combined. Its stated manufacturing plant and product range further support classification as a machinery and component manufacturer.
CertificationsThe supplier reports holding an ISO 9001:2015 certificate. This is explicit evidence of a certified quality management system, although the scope and current validity details are not provided.
Financial creditThe supplier reports registered capital, annual revenue, a 2002 establishment date, 56 employees, and a 3,295 m² plant. These details indicate an established operating entity, but the provided information does not independently verify financial stability or payment performance.
Production capacityThe supplier operates two production lines, reports a 3,295 m² manufacturing plant, offers a broad range of machinery and sanitary components, and states one-month lead times in both peak and off-peak periods. These facts support established production capability, while the fewer-than-five quality-control staff indicate a relatively lean quality organization.
Client casesThe supplier reports export sales of 71%–90% and markets in Southeast Asia, the Middle East, Europe, and North America. Trade records show shipments through Ningbo involving NKR ENGINEERING PVT LTD and several stainless-steel valve products, providing concrete transaction evidence but only one identified buyer in the supplied records.
