ELECTRONIC SERVICE FOR IMPORTERS OF HOUSEHOLD APPLIANCES IN THE "SINGLE WINDOW" SYSTEM TO PRE-DETERMINE CUSTOMS VALUE AND VERIFY ENERGY EFFICIENCY CERTIFICATES ONLINE

This thesis substantiates the introduction of an electronic service in the “Single Window” system for importers of household appliances to pre-determine customs value based on product models and electronically verify energy efficiency certificates. The service shifts the document compliance stage at the border to the pre-arrival period and does not require separate investment, as it relies on the dealer registry and price database. According to calculations, the service is expected to reduce import processing time from 156.4 hours in 2025 to 130.3 hours in 2030, a decrease of 26.1 hours, and, together with digital measures, increase the integrated customs service efficiency index from 0.718 to 0.744.
