Automatic summary, not yet reviewed
- The law creates a license system so that individuals can bring into Spain, acquire, possess or use restricted explosive precursors, such as hydrogen peroxide or ammonium nitrate. The license lasts at most one year and is granted by the Secretaría de Estado de Seguridad (State Secretary for Security).
- To grant the license, several criminal records are checked, and it can be denied if the applicant does not prove a legitimate interest or there are doubts about the intended use. The maximum deadline to decide is three months, and if there is no answer, the application is deemed denied.
- Individuals and economic operators must report theft or disappearance of these substances to the national contact point within a maximum of forty-eight hours. For individuals, this duty will not be enforced until two years after the law is published in the Official State Gazette.
- Economic operators must record every transaction with data on the customer, the substance, the quantity and the license, and keep that information for five years. They must also report suspicious transactions and may refuse them outright.
- A penalty system is set up with very serious, serious and minor offenses. Fines range from €601 to €60,000 for economic operators and from €601 to €30,000 for individuals, and activity suspensions or license revocation can be added.
- The law takes effect one month after its publication in the Official State Gazette, except for the duty of individuals to report theft or disappearance, which takes effect two years after publication.
