How do I avoid customs delays and returned-to-sender shipments on international orders?
The short answer
Get the fundamentals right every time: accurate HS code, invoice value matching the declared customs value, complete recipient details (including a working phone number for customs queries), and DDP where possible so duty isn't a delivery-time surprise the recipient refuses to pay. Most international RTOs trace back to one of those four, not bad luck, build them into a pre-ship checklist rather than trusting each courier to catch errors. Partner with a courier or aggregator that gives you visibility into customs status, so you can intervene before a parcel gets sent back automatically.
