AI-Powered supplier vetting

SummaryZhejiang Donsen Environmental Technology Co., Ltd. is a China-based limited company established in 2006, operating in construction and decoration products. The supplier reports a 16,195 m² manufacturing plant, 307 employees, more than 10 production lines, eight PPR pipe lines, over 70 injection machines, and dedicated detection equipment. Its product range includes PPR, CPVC, PVC, PE, PP fittings, pipes, valves, and related systems. ISO9001:2015 and ISO14001:2015 certifications are reported, alongside additional product certifications and exports to more than 60 countries. Evidence supports established production capacity, quality-system coverage, international market experience, and some R&D resources. However, the provided information does not sufficiently verify after-sales service, financial credibility, or specific customer cases. The records also contain a discrepancy in the stated head-office city, reported as both Yuyao and Yuhang.

Supplier typeThe supplier is identified as a combined business entity and limited company based in Zhejiang, China, with construction and decoration as its commercial sector. Its stated offerings cover plastic pipes, fittings, valves, molds, and related water, gas, and heating systems, indicating a manufacturer and product supplier rather than a narrowly specialized trading entity.

CertificationsThe supplier reports ISO9001:2015 and ISO14001:2015 management-system certificates. It also states that its products have or have obtained WRAS, GOST, NSF, UL, and CE certifications, although the provided information does not specify the exact products, validity periods, or issuing documentation for each certification.

R&D capabilityThe supplier reports five years of total R&D engineer experience, an imported PPR-AL-PPR equal-thickness wall composite pipe production line, FR-PPR fibreglass composite pipe production capability, automated feeding, and machine-based operations intended to improve precision and security. These facts support technical and process-development capability, although no patent, new-product, or formal innovation record is provided.

Production capacityProduction evidence is substantial: the supplier reports a 16,195 m² plant, 307 employees, more than 10 production lines, eight PPR pipe lines, over 70 injection machines, integrated feeding, detection equipment, and a dedicated mold factory. Its product portfolio spans multiple pipe, fitting, valve, and plastic-system categories, supporting broad manufacturing capacity.

Customization capabilityThe supplier operates a special mold factory responsible for producing various plastic fitting molds and uses multiple production lines and injection machines. This directly supports tooling and product-variation capability, but the slices do not explicitly confirm customer-specific engineering, OEM/ODM services, minimum-order flexibility, or customized design execution.

Client casesThe supplier states that its products are exported to more than 60 countries, including Venezuela, Russia, Ukraine, France, Italy, and Middle Eastern markets, and one buyer name appears in two 2025 trade records. These provide evidence of international sales activity, but no detailed customer references, project descriptions, order histories, or independently verified case studies are supplied.
