AI-Powered supplier vetting

SummaryShanghai GL Environmental Technology Co., Ltd. is a China-based limited company in Shanghai operating as both a trading company and manufacturer/factory, focused on water-treatment instruments, pumps, dosing systems, and related equipment. It reports ISO 9001 certification, three production lines, export activity beginning in 2016, self-operated import/export rights, and export markets across the Middle East, Southeast Asia, Eastern Asia, Oceania, and Africa. The supplier states that it provides technical support, has experienced engineers and an R&D team, and offers service for international partners. Production lead times are stated as within 15 working days during off-peak periods and one month during peak periods. Evidence of customization capability and broad, independently verifiable customer-case depth is limited.

Supplier typeThe supplier is explicitly identified as both a trading company and manufacturer/factory, with a legal company name, Shanghai operating location, and product coverage spanning water-quality instruments, pumps, dosing systems, and water-treatment equipment. Its representative title also identifies it as a water-treatment product manufacturer and exporter.

CertificationsThe supplier explicitly reports certification of its management systems to ISO 9001. This provides direct evidence of holding a recognized quality-management certification, although no certificate number, issuing body, or validity period is provided.

After-Sales capabilityThe supplier states that it provides technical support, careful service, application guidance, and clear product instructions for sales to other countries. These statements support an after-sales and technical-support capability, but the slices do not specify service response times, warranty terms, spare-parts arrangements, or service coverage by market.

R&D capabilityThe supplier reports a professional R&D team, engineers with 6–10 years of R&D experience, more than ten years of water-treatment application experience, ongoing product-line updates, and technology-focused development. These are explicit positive indicators of technical and innovation capability, although no patents, new-product records, or specific development outcomes are provided.

Production capacityThe supplier reports three production lines, identifies itself as a manufacturer/factory, and provides detailed specifications for new HAOSH water-pump models used in water-supply and wastewater-treatment systems. It states lead times of within 15 working days off-peak and one month during peak periods, supporting an established production and fulfillment capability.

Client casesThe records associate the supplier with buyer CHI NHÁNH CÔNG TY TNHH GREEN and show product-related trade activity involving Vietnam; the supplier also reports exporting since 2016 and serving multiple international regions. This demonstrates at least one named buyer association and export experience, but the evidence is too limited to establish a broad or independently verified portfolio of customer cases.
