"Customs Released" (also shown as "Released from Customs" or "Customs Clearance Completed") is good news — it means your package has successfully cleared the customs inspection and duty-assessment process and is now authorized to continue toward delivery.
During the customs hold stage, your shipment was checked against import regulations, its declared value was assessed for any applicable duties or taxes, and in some cases its contents were physically inspected. "Customs Released" confirms all of that is complete — there's nothing more required from a regulatory standpoint.
If duties or taxes were owed, the "Released" status normally only appears after payment has been settled, either by you directly, by the courier on your behalf (to be collected on delivery), or because the shipment fell under the destination country's duty-free import threshold.
Once released, the package re-enters the courier's normal delivery network. For domestic-style last-mile carriers, this usually means delivery within 1-3 business days. For postal-network shipments (where a national post office handles the final leg), it can take a few days longer simply due to standard postal routing and sorting after release.
It's common to see one more "Arrived at Facility" or "Out for Delivery" scan shortly after release as the package moves from the customs/bonded warehouse area to the regular delivery flow.
