⚠️ Important Notice: EU Customs Reform Effective 1 July 2026

In accordance with the latest EU Council regulations and customs guidelines, a new tariff system will take effect across all 27 EU member states (Austria, Belgium, Bulgaria, Cyprus, Croatia, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden) starting 1 July 2026.

Key Policy Change: The EU is abolishing the previous duty exemption for low-value parcels. From 1 July 2026, all goods declared through IOSS with a value not exceeding €150 will be subject to a fixed customs duty of €3 per HS tariff code category. All goods entering the EU — regardless of value — will now be subject to customs duties.

To ensure smooth customs clearance and transparent cost management, a handling surcharge of USD $5 has been applied to all standard shipments to EU countries (orders under $500). For orders over USD $500, expedited shipping remains complimentary.
