DINSEN was established in 2015 and combined with three departments:

Founded in 2015, DINSEN IMPEX CORP is registered at Xinling Building, No. 77 Renmin Road, Handan City. With a dedicated team of 10 employees, we are committed to providing high-quality Chinese cast iron pipe solutions tailored to our clients' needs.

In 2017, we jointly invested in electric furnace production equipment with our clients, achieving deeper integration with upstream suppliers. This strategic partnership has enabled us to offer more competitive pricing and shorter lead times. In 2018, we ranked first in export volume among enterprises in Congtai District.

In 2019, we successfully obtained ISO 9001 Quality Management System certification from the British Standards Institution. That same year, we expanded our online presence through Alibaba and participated in major professional exhibitions both domestically and internationally, including events in Germany, Russia, Dubai, and Vietnam, to promote our proprietary brand, DS.

In 2023, we invested USD 70,000 in our own brand's Hong Kong TSI testing and certification, marking the beginning of our branded channel development. In 2024, we established an international logistics company in partnership with a Saudi client, expanding our services to include freight forwarding, customs clearance, quality inspection, and other export-related solutions.

By 2025, our annual export turnover reached nearly USD 4,000,000, with tax contributions to the state amounting to USD 50,000.

To date, our cast iron pipe products have been exported to more than 30 countries and regions, including Germany, the United Kingdom, France, Norway, Sweden, and the United States. Among our valued clients are two publicly listed companies and a century-old Nordic brand enterprise.

At DINSEN, our entire team embraces an optimistic and proactive spirit. Through continuous learning and dedication, we strive to strengthen standardized management and enhance our capabilities to better serve diverse markets and customers. We are driven by the vision of building a world-class pipeline brand.
