How the DGT's position has evolved
Current position
Fungible components, single-use items, or spare parts (such as tubes, syringes, solutions, filters, or needles), are taxed at the general rate of 21%. The reduced rate of 10% for Value Added Tax (IVA) is reserved for products designed for the self-monitoring and treatment of disabling diseases that are for personal and exclusive use. Elements that do not meet the condition of personal use for people with disabilities do not qualify for the reduced rate.
The DGT's position has remained constant throughout the analyzed sequence. No changes are observed in the treatment of fungible components, which are systematically taxed at 21% compared to the 10% rate applied to the main systems. The doctrine is limited to reiterating the distinction between the main device and its replacement or single-use elements.
