Undeliverable shipments
A shipment is treated as undeliverable when the network cannot complete delivery within the standard attempt cycle. The exact rules vary by service tier, but the pattern is consistent.
| Delivery type | Undeliverable when | Then what |
|---|---|---|
| Business address | After 3 attempted deliveries, or after being held 5 business days from first attempt — whichever is sooner | Returned, held at carrier facility, or escalated to sender |
| Residential / B2C | After re-attempts (typically 3), or after being held 5 business days | Held at nearest courier pickup point for collection by the recipient |
| All addresses (alternate) | Address incomplete or wrong, business closed, refusal to accept/sign, customs failure, prohibited items, refusal to pay duty, improper packaging | Escalated to sender for instructions |
Customs abandonment
Customs abandonment is the specific case where the consignee refuses (or is unable) to pay the import duty and VAT on a shipment. Interdoc and the carrier network manage clearance, but cannot release the parcel until duties are paid.
- The destination customs broker holds the shipment for the local storage period (typically 30 days)
- The sender is contacted with three options: pay the duty themselves (DDP conversion), pay for return at their cost, or abandon
- If no decision is made, the customs broker may sell the goods at auction or destroy them, depending on local rules
- The sender is invoiced for all storage, handling and return / disposal costs
