However, what distinguishes it is the nature of the laws and regulations that govern it and organize its work. These are fixed laws that do not change with the change of the contract as happens in the rest of the markets. Articles stipulate Interchangeable materials have the following advantages: They are materials of great importance to the economy and of great benefit, and they can be stored.
