AI-Powered supplier vetting

SummaryNingbo RXHLi Technology Co., Ltd. is presented as a water-treatment membrane manufacturer with UF and RO production facilities, laboratory resources, six German-imported reverse-osmosis membrane lines, and 30 quality inspectors. It reports ISO9001:2015 and ISO14001:2015 certification, 3D design, ODM, OEM, and broad customization capabilities, including customization from samples, designs, and full specifications. The supplier has exported for seven years, with exports representing 11%–20% of total sales, and accepts multiple trade and payment terms. Service controls include written supplier-assessment procedures, approved-supplier records, and corrective/preventive-action procedures. However, it reports no overseas warehouses, showrooms, agents, or branches, no SDK, and no established AI model for data-driven management. Customer-specific cases are not identified in the provided information.

Supplier typeThe supplier is identified as Ningbo RXHLi Technology Co., Ltd. and is described as a water-treatment membrane technology manufacturer with UF and RO production lines, rolling equipment, water-testing equipment, and a laboratory. Its seven years of export activity and stated self-operated import/export rights also support classification as a manufacturing supplier with international trading capability.

CertificationsThe supplier explicitly reports ISO9001:2015 and ISO14001:2015 certificates. These provide direct evidence of certified quality-management and environmental-management systems.

R&D capabilityThe supplier provides 3D software design, reports new products in the past year, and offers ODM services. Its reported lack of an SDK and lack of an established AI model for big-data decision support indicate limitations in certain technology capabilities, but do not negate the documented product-development and design activity.

Production capacityThe supplier reports six German-imported reverse-osmosis membrane production lines, UF and RO flat-sheet lines, domestic and industrial rolling machines, water-testing equipment, a laboratory, and 30 quality inspectors. It also states that finished products are inspected using written instructions that are uniformly followed, providing direct evidence of established production and quality-control resources.

Customization capabilityThe supplier explicitly supports customization from samples, designs, full customization, flexible customization, and minor customization, together with 3D software design services. These statements directly indicate broad customization capability.

Product Q&A

Q:Is your company a manufacturer or trading company?

We are a manufacturer with our own factory and cooperate with other factories using our technology. RTL has 9 years of experience in reverse osmosis membranes with independent R&D.

Q:What is the minimum order quantity (MOQ)?

MOQ varies by model. For household membranes, it is 1000 pcs. For industrial membranes, it is 100 pieces. OEM orders may have different requirements.

Q:What are the advantages of your products?

Our technical advantage lies in high desalination technology. Household membranes handle 3,000-6,000 ppm water, while seawater membranes handle 30,000-40,000 ppm with obvious cost advantages.

Q:What is the quality guarantee if there is a problem?

We maintain zero customer complaints. If a quality problem is verified, we guarantee replacement and are responsible for freight costs according to our verification process.

Q:What is the lead time for production?

Peak season lead time is one month. Off-season lead time is within 15 workdays.
