With the rapid development of import and export trade, air import has gradually evolved into a synonym for imported products, highlighting that the goods are original products imported from abroad to prove their quality.

Air freight has gradually become the dominant mode of transportation. Because its timeliness and safety are higher than other modes of transportation, the market share of air freight has increased year by year. It is not difficult to see from the statistics of the total import and export trade of my country's customs in recent years that the proportion of air imports has also increased significantly.
