Settled doctrine Medium confidence 62 rulings · 2014–2026

Current position

Transformation implies a manufacturing process that converts raw materials into products with different characteristics, such as the sterilization or pasteurization of preserves. The butchering of meat is considered an exploitation and transformation activity. Conversely, the packaging, conditioning, or mixing of natural products without altering their essence does not constitute transformation.

The DGT maintains a constant distinction between simple handling (packaging, mixing, or conditioning) and industrial transformation. Throughout the rulings, it has been delimited that transformation requires a change in the characteristics of the product or a manufacturing process, whereas the resale of products without processing activities maintains specific regimes such as the equivalence surcharge.

Turning points

  1. V0141-18

  2. V5185-26

    Defines transformation as an industrial activity that produces goods with different characteristics, citing sterilization or pasteurization as examples of manufacturing.
