AI-Powered supplier vetting

SummaryQinghe County Hongli Rubber and Plastic Co., Ltd. is a China-based limited company and factory established in 2004, operating from a 3,000 m² manufacturing site in Qinghe County, Hebei. It produces sealing rubber products, safety-related rubber components, rubber strips, mats, and related items, including customized products. The supplier reports more than 10 production lines, annual sealing-strip output of 50 million meters, and a one-month lead time in both peak and off-peak seasons. Its export activity is relatively recent, beginning in 2023, with domestic markets identified as its primary market and exports representing 21%–30% of sales. The company claims quality-management practices and product innovation, including a safety rubber switch series, but reports no supplier management-system certifications. Evidence is insufficient to assess after-sales capability, financial credibility, and customer cases.

Supplier typeThe supplier is explicitly identified as a factory and limited company in China, operating in manufacturing from Matun Industrial Zone, Qinghe County, Hebei. Its 3,000 m² plant and rubber-product manufacturing focus support classification as a direct manufacturer rather than only a trading company.

CertificationsThe supplier explicitly reports no supplier management-system certifications. Although it claims to maintain a quality management system and professional technical personnel, no externally recognized certification is provided.

R&D capabilityThe supplier describes itself as innovative and reports launching a safety rubber switch series, while expanding from one sealing-product category into four product series, including safety contact tape, fireproof expansion seal, high-conductive shielding rubber, and sealing products. These stated product developments provide explicit evidence of product innovation, although no independent technical performance data is supplied.

Production capacityThe supplier reports a 3,000 m² manufacturing plant, more than 10 production lines, annual sealing-strip output of 50 million meters, and a one-month lead time in both peak and off-peak seasons. These figures indicate established production capacity, though the slices do not verify utilization rates or capacity for every listed product.

Customization capabilityThe company explicitly states that it produces special products according to customer requirements and offers multiple rubber-product series, including sealing strips, safety components, mats, and related products. This directly supports customization capability for rubber products, although the scope of engineering support and tooling capability is not specified.
