Currently, many regions in China are in the critical period of spring sowing and preparation, which also requires ample supplies of fertilizers and other agricultural materials. The demand for spring agricultural materials is high, with a significant increase in the transportation volume of such materials. To ensure agricultural production, China imports a large amount of fertilizers from abroad every year to meet the demand for spring fertilization. Therefore, timely customs clearance and transportation of imported fertilizers play an important role in ensuring spring sowing and promoting increased crop yields.
