In an era of global logistics expansion and infrastructure transformation, the China National Heavy Duty Truck Group Company Limited has emerged as an undisputed leader. As the parent organization behind the iconic HOWO and SITRAK brands, this industrial powerhouse supplies millions of Sinotruk howo parts to fleet operators across six continents. The China National Heavy Duty Truck Group Company Limited has not only dominated the domestic market for decades but has also rewritten the global heavy truck sales charts, proving that Chinese manufacturing can compete—and win—on the world stage. From the copper mines of Zambia to the construction sites of Peru, the group’s vehicles and components are trusted for their durability, efficiency, and unmatched parts availability.
The story of the China National Heavy Duty Truck Group Company Limited begins nearly a century ago. Originally founded in 1930 as the Jinan Automobile Manufacturing General Factory, the enterprise has grown into China’s largest heavy-duty vehicle production base and the cradle of China’s heavy truck industry. In 1956, it formally established SINOTRUK, cementing its position as China’s first heavy-duty truck manufacturer. However, the pivotal moment arrived on November 28, 2007, when the group was listed on the Main Board of the Hong Kong Stock Exchange as a red-chip company, marking its entry into global capital markets.
Today, the China National Heavy Duty Truck Group Company Limited operates a vast manufacturing ecosystem that includes 37 KD assembly plants across 27 countries, nine production bases, three R&D centers, and two big data centers, with a workforce of thousands of engineers and technicians dedicated to advancing heavy truck technology.
The year 2025 will be remembered as the moment the China National Heavy Duty Truck Group Company Limited cemented its status as a true global powerhouse. Total vehicle sales for the year exceeded 440,000 units—a staggering 22.5 percent year-on-year increase—with heavy-duty truck sales reaching 300,000 units. These figures not only secured the company’s fourth consecutive year as China’s number-one heavy truck manufacturer but also propelled it to an unprecedented milestone: the global heavy-duty truck sales championship.
The group’s export performance was equally extraordinary, with heavy-duty truck exports surpassing 153,000 units in 2025, representing a 14.4 percent increase year-on-year, marking the 21st consecutive year that the China National Heavy Duty Truck Group Company Limited has held the top position in China’s heavy truck export sector. In September 2025 alone, monthly exports broke the 15,000-unit barrier for the first time, setting a new industry record that the group itself would shatter just four months later.
The manufacturing philosophy of the China National Heavy Duty Truck Group Company Limited rests on a foundation of rigorous quality management. All affiliated manufacturing units under the group have passed IATF 16949:2016 certification—the globally recognized automotive quality management standard that emphasizes continuous improvement, defect prevention, and variation reduction throughout the supply chain. Additionally, the organization maintains ISO 50001:2018 Energy Management, ISO 14001:2015 Environmental Management, and ISO 45001:2018 Occupational Health and Safety certifications.
The group’s commitment to quality is reflected in its annual customer satisfaction score of 96.1 points, a testament to the reliability of its products and aftermarket support. For fleet operators choosing the China National Heavy Duty Truck Group Company Limited as their parts supplier, this translates into components that are not only engineered to original specifications but also rigorously tested to withstand the harshest operating environments.
One of the key advantages of sourcing from the China National Heavy Duty Truck Group Company Limited is its unparalleled global logistics network. With products exported to more than 150 countries and regions across six continents, the group has established a dense network of service centers, genuine parts depots, and technical support teams in major markets including Nigeria, Ghana, South Africa, Angola, Uganda, and throughout the Middle East and Southeast Asia.
This infrastructure ensures that certified parts suppliers can fulfill orders with remarkable speed—whether through sea freight to coastal ports (delivery in 30–35 days) or via urgent air freight for emergency repairs (delivery in 7–10 days). Case in point: following the group’s 2025 Global Partners Conference in Qingdao, which brought together distributors from more than 50 countries, orders for complete vehicle assemblies and aftermarket components surged, validating the trust that global partners place in the China National Heavy Duty Truck Group Company Limited as a premier parts supplier.
The strategic collaboration between the China National Heavy Duty Truck Group Company Limited and Weichai Power (part of the Shandong Heavy Industry Group) is a defining feature of its competitive edge. Weichai (Hong Kong) and Sinotruk (Hong Kong) jointly manage listed company operations, external investments, and financing, creating a synergistic ecosystem that drives innovation from engine development to final vehicle assembly.
The 2025 Shandong Heavy Industry-Weichai Power Global Partners Conference, themed “Technology Empowers Better Equipment,” further deepened this collaboration, with strategic agreements signed with Huawei Digital New Energy Technology Co., Ltd. and China Export & Credit Insurance Corporation to expand overseas market collaboration. For customers sourcing from the China National Heavy Duty Truck Group Company Limited, this integrated supply chain means that every component—from high-pressure fuel injection systems to turbochargers and electronic control units—is designed and tested to work in perfect harmony, reducing downtime and maximizing vehicle productivity.
