I guess we'll just have to ship it in small batches and cross our fingers
You might want to do a test run first with something else - a bottle of aspirin for example. I foresee two problems with shipping medication. The first is the general hassle of shipping something to Peru from another country. The second is that it is an expensive medication.
Recently a family member shipped (via FedEX) a $32 Lego toy to my son, as a test to see how shipping would go. Here is what happened:
- Day 1, package dropped off at FedEX location in the US, shipped using International Priority
- Day 2, I received an email from the local FedEX saying that the package was in Customs and I needed to provide a copy of the original sales slip (so they could assess the value)
- I spent the next day or so getting a copy of the original receipt and filling out other Customs forms.
- Day 9, I was informed by the local FedEX that I would have to pay $45 to get it out of Customs and delivered to my office
- Day 11, I made the bank transfer and provided proof of payment to local FedEX
- Day 13 - package was delivered
The end result is that it took almost 2 weeks and an additional $45 to get a $32 Lego toy. Part of the delay was on my end because it wasn't urgent - I probably could have gotten it through more quickly. I'm sure others here have similar horror stories. I can only imagine that the process for receiving an expensive medication would involve even more steps.
If your medication is refrigerated, your situation is worse because you cannot wait several days. I suggest you talk with the local delivery service (FedEX, UPS, DHL, whoever) to find out what you need to do beforehand to expedite the process with Customs. Don't trust what the people in the US may tell you, make sure you talk to someone down here. And even then, you can't trust them because rules and regulations always change. I think you would probably need some kind of invoice with the value of the medication and some type of approval from the Peruvian authorities to import it into Peru.
Another option is to use an on-board courier service that accepts medications. But if you are going to pay those prices, you might as well travel yourself or buy a ticket for a friend or relative.
