Compliance in EU: What Sellers Need to Know  

​Comprehensive Guide to EU Compliance for Sellers


The European Union, with its 27 member states and population of over 450 million, offers immense opportunities for businesses but requires adherence to complex regulatory frameworks. As of 2025, sellers must navigate updated VAT rules, product safety standards, consumer protection laws, and customs procedures. This guide distills essential compliance requirements for both EU-based and international sellers, ensuring smooth market entry and sustainable operations.  

VAT Compliance: Central to EU Market Access


One Stop Shop (OSS) Simplification

Introduced in July 2021, the One Stop Shop (OSS) system revolutionizes VAT compliance by enabling businesses to declare and pay VAT across all EU member states through a single portal. Key schemes include:

·       Union OSS: For EU-established businesses selling goods/services to consumers in other EU countries.

·       Non-Union OSS: Allows non-EU businesses to register in one member state for B2C digital services.

·       Import OSS (IOSS): Simplifies VAT payment for goods under €150 imported into the EU, eliminating border VAT charges.

Registration thresholds vary:

·       Cross-border B2C sales: €10,000 annual EU-wide threshold.

·       Domestic thresholds: Ranging from €15,600 (Cyprus) to €85,000 (France for goods.

·       Digital services: Mandatory VAT registration from the first euro for non-EU sellers.

Marketplaces now bear joint liability for VAT compliance, requiring automated VAT number validation via the VIES system.
