Plant protection products (PPP) are preparations intended for the protection of plants against harmful organisms, diseases, and weeds. In the Republic of Slovenia, only PPPs that are approved for marketing and use in the territory of the Republic of Slovenia may be used. Due to strict restrictions on the use and marketing of PPPs, their entry into the customs territory of the EU and the territory of the Republic of Slovenia is controlled. Only legal and natural persons who have a permit from the Slovenian Administration for Food Safety, Veterinary Medicine and Plant Protection (hereinafter UVHVVR) to trade in PPPs and are entered in the register of distributors may trade in PPPs.

The introduction of PPPs into the EU customs territory is only permitted through designated entry points or other authorized points. Before release for free circulation, the importer or his representative must notify the competent inspector of the UVHVVR, who will carry out an inspection. Until the UVHVVR inspector authorises their entry into the EU customs territory, the customs authorities may not release them for customs-approved use or application. If a consignment is discovered that has not yet been checked by a UVHVVR inspector, the customs authority shall notify the competent regional office of the UVHVVR. Only with the approval of the UVHVVR office may such a consignment be released for customs-approved use or utilization.
