| 1 | Recipient Refusal | The recipient declines the parcel at the door or refuses to accept delivery. | Final-mile delivery, especially for cash-on-delivery or unexpected shipments. | The order may be canceled after dispatch, while return freight and handling costs can still apply. | Show the final payable amount, delivery terms, return policy, and product details before shipment. |
| 2 | Recipient Unavailable | No one is available to receive the shipment after the carrier’s permitted delivery attempts. | Residential addresses, workplaces with restricted receiving hours, and remote locations. | The buyer may lose delivery time and may need to pay additional reshipping or address-update costs. | Provide a reachable phone number, preferred delivery window, and an authorized alternate recipient. |
| 3 | Incomplete Address | Missing apartment, building, district, postal code, province, or other required address details. | Cross-border orders where address formats and mandatory fields differ by country. | The parcel can be delayed, held for clarification, or returned without reaching the buyer. | Use country-specific address fields and validate postal codes, phone numbers, and locality names. |
| 4 | Incorrect or Unserviceable Address | The address is wrong, does not exist, lies outside the service area, or cannot be safely accessed. | Rural regions, military or restricted zones, apartment complexes, and newly developed areas. | Address correction may not be possible after dispatch, and the shipment can be returned automatically. | Confirm the complete standardized address and verify delivery coverage before accepting payment. |
| 5 | Customs Documentation Failure | Missing, inconsistent, or insufficient commercial invoices, product descriptions, origin details, or import information. | Import customs clearance before the parcel enters the destination market. | The shipment may be held, assessed, rejected, or returned, creating delays and possible clearance charges. | Use accurate product descriptions, declared values, country-of-origin details, and required customs codes. |
| 6 | Unpaid Duties or Taxes | The buyer does not pay assessed import duties, taxes, brokerage fees, or other destination charges within the required period. | Destination customs, carrier payment portals, or delivery handoff. | The buyer may face unexpected costs, storage fees, or a return after the payment deadline. | Display whether duties and taxes are prepaid or payable on arrival, with a clear landed-cost estimate. |
| 7 | Restricted or Prohibited Goods | The product, ingredient, battery, quantity, or packaging does not meet destination-country import or transport rules. | Export screening, airline transport, customs inspection, or local regulatory review. | The shipment may be seized, destroyed, delayed, or returned, and refunds may be limited by law or policy. | Check destination-specific rules for batteries, liquids, medicines, food, cosmetics, and controlled products. |
| 8 | Uncollected Pickup-Point Parcel | The buyer does not collect the parcel from a locker, post office, depot, or collection point before the holding period expires. | Out-of-home delivery networks and locations with limited storage periods. | The parcel is returned even though delivery to the selected location was technically completed. | Confirm the pickup location, collection deadline, identification requirements, and notification method. |
| 9 | Label or Barcode Failure | The shipping label is unreadable, damaged, duplicated, incorrectly attached, or does not match the electronic shipment record. | Warehouse dispatch, sorting facilities, or carrier processing centers. | Tracking may stop updating, routing can fail, and the parcel may be returned without a successful delivery attempt. | Verify label readability, barcode accuracy, package durability, and alignment with the order record. |
| 10 | Carrier or Network Exception | Severe weather, transport disruption, route closure, operational failure, security issue, or loss of service coverage prevents delivery. | International line-haul, customs transfer, regional sorting, or final-mile networks. | Delivery may fail despite a correct order and address; refund or reshipment depends on the seller’s policy and shipment status. | Choose a service with destination coverage, monitor tracking milestones, and define a clear exception-escalation process. |
