My experience with international shipping is limited, but I do know that every country has different import/export rules and customs procedures. That being said, it's definitely possible that the $2200 value of the item (and/or other factors) triggered an inspection.
Depending on the countries and carriers involved, there may or may not be ways to track the item if it's delayed in customs.
Thanks for the response. I’ll contact eBay to see if this affects my dispute- if, the seller decides not to pay for custom charges (if there are any).
