SF express. Because the express delivery speed is super fast, SF Express has also developed a new express delivery mode for fresh products, called SF Cold Chain Express. This express delivery is specially designed for transporting fresh products, and it is mainly divided into two modes: one-day delivery and the next-day delivery. Here, we suggest that you choose the same-day delivery when choosing, because the freshness of fresh products is very important. If it takes too long, it will definitely have adverse consequences on the quality of fresh products, and the next-day delivery is not the second day arrival in people's sense. Moreover, SF promised that the goods would not be paid for any problems within 72 hours during the transportation process, so for fresh food, the sooner they arrive, the better. Therefore, Rizhao Zibo seafood can be sent by SF cold chain express.
