MSC stands for Minimum Shipping Charge. It is the minimum amount that must be paid for shipping, regardless of the weight or volume of the shipment. This charge is typically applied to small or lightweight shipments that would otherwise be unprofitable for the shipping company.
MGW stands for Minimum Gross Weight. It is the minimum weight that must be considered when calculating the shipping cost of a shipment. This weight includes the weight of the goods, as well as the weight of the packaging and any other materials used to secure the shipment.
In general, MSC is applied to shipments that have a low weight and volume, while MGW is applied to shipments that have a high weight and volume. This is because the shipping cost of a shipment is often based on its weight and volume, and these two terms help to ensure that the shipping company is compensated fairly for the services they provide.
