Customs-clearance rates vary by destination, product, quantity, documentation and current enforcement practices. We cannot predict whether an individual package will clear customs or provide a reliable success percentage without current shipment data.
Standard parcels dispatched from outside the EU may be inspected, delayed, returned or seized. Guaranteed EU Delivery uses a specialised EU route and provides refund or reshipment coverage for qualifying orders under the service terms, but it does not exempt packages from customs controls or guarantee that they will clear inspection.
