Accelerated transit is not a term that is commonly used in the context of Shein orders. However, "in transit" is a status that appears in Shein tracking and it means that the package is moving between locations. This status can appear when the package has already arrived in the destination country and is moving between customs, the distribution center, or the local delivery office. As a result, the package shouldnt take long to be delivered. Although its not common, this status can also appear when the order is moving around in the country of origin (China) .
