Any matters not covered herein shall be subject to the relevant provisions of GB/T26075-2019.

2. When the order quantity is less than 100 tons, it is required to use only one heat number. When the order quantity exceeds 100 tons, efforts should be made to ensure that the quantity per heat number is no less than 100 tons, with the principle of minimizing the number of heat numbers. During the supply process, the steel mill should strictly adhere to the first-in, first-out (FIFO) principle to ensure that shipments are made in the order of heat numbers. If goods from the same heat number need to be shipped in batches, the continuity of shipments must be ensured, and goods from other heat numbers must not be interspersed during the shipping process.
