  • Parcel Handling Fees: Postal carriers charging additional fee surcharges for clearing customs.
  • Dropshipping Taxes: Determining who serves as the importer of record (merchant vs. end-consumer).

What is the EU IOSS system?

The Import One-Stop Shop (IOSS) allows e-commerce sellers to collect VAT at checkout for goods valued under €150 imported into the EU, speeding up customs clearance.
