On February 17, 2017, the customer commissioned Huifeng International to transport a batch of instruments to South Korea by air. This batch of goods was to participate in the exhibition in South Korea in early March, but it had to be sent abroad for testing before being sent to the exhibition site, so the customer required that the goods be delivered to Incheon, South Korea before February 28. Normally, it is necessary to wait until the goods arrive at the airport before submitting the relevant application documents to the customs for approval. After the customs approval, an approval decision letter will be issued. The approval time of Changsha Customs is 7-15 working days, and the approval time of Beijing Customs is 21 working days. This batch of goods is time-sensitive and the task is heavy. Huifeng International used its own agent China Southern Airlines' direct flight from Changsha to ICN, and operated it in a temporary entry and exit mode without ATA. The goods were successfully delivered to Incheon, South Korea on February 25, giving the customer plenty of time to test and set up the exhibition. Mission must be accomplished is the belief that Huifeng International has always adhered to!
