Semi-Trailer Market Rebounds Strongly in Q1 2026, Zonxin Auto Parts Empowers High-Quality Industry Development

In the first quarter of 2026, China’s semi-trailer market experienced a strong rebound, with vitality continuously released across the entire industrial chain. According to data from the China Association of Automobile Manufacturers, cumulative domestic sales of semi-trailer tractors reached 162,800 units from January to March, representing a significant year-on-year increase of 20.38%. In March alone, sales hit 72,300 units, surging 101.16% month-on-month and marking the highest monthly level for the same period in the past three years, injecting strong momentum into the development of the semi-trailer industry.

As a benchmark enterprise in the core components sector of semi-trailers, Shandong Zhongxing Auto Parts Co., Ltd. has seized market opportunities by leveraging technological innovation, stringent quality control, and efficient production capacity, providing solid support for the industry’s recovery and demonstrating the responsibility and commitment of a leading domestic auto parts manufacturer.

Strong Demand Growth Drives Industry Recovery
In Q1 2026, China’s logistics and transportation sector continued to recover, while trends such as new energy transition and lightweight upgrades further boosted demand for semi-trailers. Across key segments, demand in general cargo transport, port trunk logistics, and cold chain logistics rebounded comprehensively, driving sales growth in stake trucks, skeletal container trailers, and refrigerated trailers.

Industry data shows that the ratio of tractors to trailers is approximately 1:1.1–1:1.3. Based on this, the estimated demand for semi-trailers in Q1 reached 179,000 to 212,000 units, indicating a continuously expanding market.

Meanwhile, the pace of new energy transformation accelerated. Sales of new energy tractors reached 45,000 units in Q1, with penetration rising to 27.3%. Battery-electric heavy trucks accounted for over 70%, while battery-swapping models exceeded 25%, making electrification a core development direction for the industry. Against this backdrop, demand for lightweight, high-reliability, and long-lifecycle core components has surged, pushing upstream parts manufacturers to accelerate technological iteration and product upgrades.
