I'm afraid it isn't. "Someone comes to your house" presumes that the repair service is being performed in a particular jurisdiction and would be subject to whatever consumer protection laws exist where you live, regardless of where the repairman lives.
The laws covering international shipping of goods are far more complex, not to mention the contracts between the courier and their customer (the seller). The couriers tend to have a lot of "weasel" language in the their agreements that allow them a lot of latitude when items aren't delivered or have customs issues. The amount of latitude allowed in their agreements likely varies from country to country based on what liabilities the law in any country will allow them to avoid.
Couple this with the tendency of some sellers to not properly declare goods to avoid customs issues and you have a real mess.
This is why you have to protect yourself and not rely on someone else when doing business internationally.
