How the DGT's position has evolved
Current position
The amount of recycled plastic to be excluded from the tax base must be certified by an entity accredited under the UNE-EN 15343:2008 standard or its replacement standards. In the case of chemically recycled plastic, if no specific certification scheme from an entity accredited by ENAC or an EU equivalent exists, it may be certified in accordance with the evidentiary rules of the General Tax Law. The lack of a certificate at the time of accrual implies that the total weight of the packaging will be counted as non-recycled plastic.
The DGT's position has moved from allowing a manufacturer's responsible declaration during the first 12 months to requiring certification from an accredited entity. Following the expiration of said transitional period, it has been specified that the absence of certification leads to taxation on the total weight of the packaging. The accreditation of chemically recycled plastic has been nuanced in the absence of specific certification schemes.
Turning points
-
Establishes that, in the absence of a specific certification scheme for chemically recycled plastic by an accredited entity, the evidentiary rules of the General Tax Law may be applied.
-
Clarifies that if the manufacturer does not possess the certificate from the accredited entity at the time of accrual, the total weight of the packaging will form part of the tax base.
