Generally, the delivery price of freight yard or steel mill includes tax. Because most of the price information is provided by steel mills or dealers (some building materials and other groups can be added, and there are many quotations in the group), the price information is not very accurate and can only be used as a reference. The actual delivery may be much more favorable (this should be discussed with the dealer). Freight is the cost from the place of delivery to the place where the goods are used. Many steel mills offer regional preferential treatment to places far away or with great market potential, and the quotations are lower than those in other places, so they transport by train. Hehe, having said so much, I don't know if I can understand it, but I can exchange it when I have time.
