How the DGT's position has evolved
Current position
Manufacturing involves the transformation of products to fulfill a specific function, such as the case of plastic packaging or hydrogen intended for fuels. The mere manipulation of semi-finished products, such as coils or liquid polymers, which require a subsequent transformation phase, is not considered manufacturing. The production of taxable products requires registration in the corresponding registries and compliance with sectoral regulations.
The DGT maintains a clear distinction between manufacturing and the mere manipulation of semi-finished products. While the obtaining of hydrocarbons or hydrogen for fuels is classified as manufacturing, the transformation of coils or liquid polymers does not reach this status. The doctrine has remained consistent in delimiting the objective scope of the tax through the final function of the product.
Turning points
-
Establishes that the production of packaging from semi-finished products such as coils does not constitute manufacturing.
-
Defines liquid polymer as a semi-finished product as it requires a subsequent transformation phase to fulfill its function as packaging.
