The EU Just Changed the Rules Effective July 1, 2026
Selling into Europe’s 450 million consumers has always required navigating complex VAT rules. In 2026, two major updates have made the stakes even higher and choosing the wrong scheme now costs more than ever.
From July 1, 2026, the EU abolished the customs duty exemption for low-value parcels under €150. A flat-rate €3 customs duty per consignment now applies to all low-value imports entering the EU. This change was originally planned for 2028 but was accelerated significantly. Combined with stricter enforcement of IOSS and OSS registrations, 2026 marks a genuine turning point for cross-border e-commerce into Europe.
IOSS vs Union OSS : The Core Difference
The single most important distinction is where your inventory is located at the time of sale.
Use IOSS when shipping low-value consignments of €150 or less from outside the EU directly to EU consumers it speeds customs clearance and handles import VAT in one step. Use Union OSS when you dispatch goods from one EU country to another or sell digital services inside the EU.
In plain terms: if your goods are sitting in a Chinese or US warehouse and shipping directly to a buyer in France, that is IOSS. If your goods are already inside an Amazon FBA warehouse in Germany and selling to Italy, that is Union OSS. Using the wrong scheme results in double taxation, customs delays, and potential account suspension.
What Changed for IOSS in 2026
IOSS remains the primary VAT tool for non-EU sellers shipping low-value goods but its role has fundamentally expanded.
From July 1, 2026, the new €3 customs duty is integrated directly into the IOSS system. IOSS-registered sellers collect both the VAT and the €3 duty at checkout, enabling instant customs clearance. Non-registered sellers face a two-lane system where goods are held at customs and duties are recalculated at entry creating delays and double charges for customers.
The €3 customs levy applies to goods sold by non-EU merchants registered under IOSS. According to EU estimates, this captures around 93% of all e-commerce parcels imported into the EU making the measure highly impactful from day one.
Your IOSS number is now more than a VAT reporting tool. EU customs systems electronically validate IOSS numbers against declared goods values at the border. If your IOSS number is not properly transmitted in the customs declaration data, the system recalculates VAT at entry creating double charges for your customer even if you collected VAT at checkout.
Non-EU sellers cannot register for IOSS directly. If your business has no EU establishment, you must appoint an EU-established intermediary to register on your behalf and handle your IOSS obligations.
What Changed for Union OSS in 2026
The €10,000 pan-EU threshold still applies once you exceed it, every cross-border B2C sale is included in your quarterly OSS return at the buyer’s local VAT rate. Filing is consolidated through a single EU member state, eliminating the need for separate VAT registrations in every country you sell into.
For Pan-EU FBA sellers specifically, the Amazon VCS shipment-level change from June 2026 means your OSS filings must accurately reflect which country inventory shipped from not just where the buyer is located. Mismatches between your OSS returns and Amazon’s internal reporting to EU authorities now trigger automated audits.
What’s Coming in 2028
The July 2026 €3 customs duty is only the first step. The EU Customs Data Hub launching in 2028 will impose full tariff-based duties on all imports regardless of value. IOSS sellers must prepare for both the July 2026 transition and the more comprehensive 2028 reform.
Businesses that build compliant IOSS and OSS infrastructure now will transition into 2028 with significantly less disruption than those who wait.
