Definition of a precursor: a starting substance is a substance that participates in a chemical reaction where another compound is produced, such as an explosive substance.
A large number of precursors/source substances may only be sold to people who must use the substances in connection with their profession. The background is that these chemicals will be able to be used in the illegal manufacture of explosives.
Control of the sale of precursors/starting substances that are subject to restrictions to professional users: The following information must be available in the form of a customer declaration for each individual transaction:
This information must be stored for 18 months after the transaction
No, a customer declaration can apply for one year at a time.
Provided that the customer (AU) has been checked within a year before the current transaction and if it does not differ significantly from previous transactions, otherwise it is done for each purchase.
If the above cannot be fulfilled, a customer declaration must be completed for each purchase.
Table 1: Precursors/starting materials for explosives subject to restrictions:
Chemicals subject to restrictions require a customer declaration: | |
Name of chemical: | Threshold: |
Nitri acid | >3% |
Hydrogen peroxide | >12% |
Sulfuric acid | >15% |
Nitromethan | >16% |
Ammonium nitrate | >16% |
Potassium chlorate | >40% |
Potassium perchlorate | >40% |
Sodium chlorate | >40% |
Sodium perchlorate | >40% |
For the substances listed in Table 1, a precautionary procedure for proper storage and surveillance/monitoring shall be put in place.
A safety procedure for proper storage and surveillance/monitoring must be put in place.
In case of significant disappearances and thefts of precursors/precursors, it must be reported to the police to the nearest police district within 24 hours of discovery.
The rules in this area can be found in an EU regulation on explosives precursors and the Ministry of Justice's executive order on explosives precursors:
