Reverse logistics encompasses the processes of handling returns, refunds, repairs, recycling, and disposal of products sold on Amazon or other EU marketplaces, ensuring compliance with EU regulations like WEEE, PPWR, and GDPR while integrating with fulfillment tools like Fulfillment by Amazon (FBA) and Amazon Global Logistics (AGL). In the EU’s €70 billion+ e-commerce market (2025 projection), efficient reverse logistics minimizes costs, maintains customer trust, and aligns with sustainability mandates amid the $1.21 trillion global cross-border B2C sales landscape. Amazon’s tools streamline returns and compliance, while third-party services enhance flexibility for Fulfillment by Merchant (FBM) or multi-channel sellers. Below, I detail Amazon’s reverse logistics solutions, third-party tools, EU regulatory considerations, and practical tips, connecting to prior discussions on fulfillment, customs, and compliance.
