eBay shipping errors stem from missing/invalid shipping service codes, incorrect package dimensions, weight outside service limits, or destinations not allowed for the shipping service selected.

1. Use valid ShippingServiceCode values from the GeteBayDetails API — these vary by site (US, UK, etc.) and change periodically.
2. Provide accurate package dimensions (L×W×H) and weight — eBay calculates rates and rejects out-of-bounds values.
3. Don't ship to destinations the carrier doesn't serve — use ExcludeShipToLocation to remove unserviceable countries/regions.
4. Set up a shipping policy in Seller Hub → Business Policies — much easier than per-listing shipping settings.

• Missing shipping rate for international ShipToLocations — listing fails internationally even if domestic works
• Using a USPS Flat Rate service code with package dimensions that don't fit a flat rate box
