Taipei: Chunghwa Post Co. suspended services on July 1 for online sellers using the Import One-Stop Shop (IOSS) system to ship goods valued at pound 150 (US$171) or less to European Union nations, following a change in EU tariff rules, the company said.

According to Focus Taiwan, the suspension followed the EU's decision to end tariff exemptions for such imports, requiring instead that a pound 3 customs duty be paid per item at the time of shipment, effective from July 1. Because Chunghwa Post currently lacks the infrastructure to process the new duties under the required "Delivered Duty Paid" (DDP) protocol, it suspended IOSS shipments on July 1.

Launched by the European Union in 2021, the IOSS is a digital platform designed to simplify tax compliance for international e-commerce. The system allows online sellers outside the EU to collect value-added tax from customers at the time of purchase for small packages valued at pound 150 or less.

Shipments sent between private individuals remain exempt from these new customs duties, provided they meet certain criteria, including a value of pound 45 or less. Chunghwa Post noted that EU-bound mail accounted for 2.4 percent of its international mail volume in 2025, with IOSS-registered business parcels representing 15 percent of that subset.
