Norbolsa || The electronic refund system established for importing companies to recover illegally charged tariffs came into operation this week, and thousands of companies rushed to submit claims. The system has some flaws, such as loading issues, but it did not collapse and accepts file submissions according to the first applicants. It is expected to refund $166 billion to importers according to a court order, but it is unclear whether the timeliness of the request affects the speed of processing the refund.
