IAE Classification: Paper or Melamine in Article Manufacturing?

The correct determination of the heading in the Economic Activities Tax (IAE) is a critical aspect for the legal certainty of manufacturing companies. An erroneous classification can lead to inconsistencies in the activity declared to the Tax Administration.

What the DGT has resolved

The Dirección General de Tributos (DGT) has addressed the doubt regarding whether the manufacture of decorative paper impregnated with melamine should be classified under heading 473.4 (Manufacture of decorative and household articles of paper and cardboard) or heading 482.2 (Manufacture of finished articles of plastic materials). The criterion establishes that classification in the IAE Tariffs must be carried out by considering the true material nature of the activities.

According to the resolution, the determining factor is the composition of the final product:

• If the raw material is fundamentally cellulose or paper and the melamine acts solely as a secondary support, the activity corresponds to heading 473.4.
• If melamine is the predominant component and the paper functions as a secondary support, the activity must be classified under heading 482.2.

What it means for you

For companies dedicated to manufacturing products composed of different materials, such as impregnated paper, the distinction does not lie in the manufacturing process, but in the preponderance of the components. This distinction is necessary to correctly apply the Instruction for the application of the IAE Tariffs (RD Leg. 1175/1990) and the TRLRHL (RD Leg. 2/2004).

An incorrect classification based on an erroneous interpretation of the predominant material could generate discrepancies in the company's compliance with tax obligations.

What should be done

It is necessary to analyze the technical composition of the manufactured products to identify which material constitutes the essence of the article. It is recommended to verify whether melamine or paper is the main element in the structure of the final product before proceeding with the assignment of the IAE heading. Each case requires a technical analysis of the raw material to ensure compliance with current regulations.
