How the DGT's position has evolved
Current position
The status of a reusable container is determined by whether the product has been conceived, designed, and marketed to undergo multiple rotations or to be refilled. This is an objective condition that does not depend on the user's will or behavior. Once marketed as reusable, the law does not require it to be effectively reused. To prove this, certifications under the UNE-EN 13429:2005 standard or other means of evidence may be used.
The DGT's position has moved from addressing objective configuration within the scope of subsidized diesel to applying it specifically to the concept of reusable containers. In the latter area, the doctrine has consolidated by defining reuse as a design and marketing characteristic, decoupling it from the user's will. Furthermore, the validity of specific means of evidence to prove such a condition has been specified.
