I deal in international stuff all the time, here are a few quick tips:
- Be aware of import/export tariffs, those can bite you if you're not careful.
- Stick to trusted payment systems (PayPal, Credit Cards). Avoid Debit Card purchases and Wire Transfers, no matter what.
- Be aware of currency exchange rates, as they can sometimes fluctuate between when you order and when you're actually charged for the purchase.
- Sale or trade of endangered woods, plants and animals falls under the CITES treaty, and packages can get confiscated if custom's officials even suspect that a package contains something that violates those rules. Brazilian rosewood is probably the most famous wood type that's impacted, but there are many more.
- It's always good to inquire about packing. The heavier something is, the easier it is to get damaged if its not packed tightly. Also, I've received some shipments lately where the goods were packed using solid chunks of polystyrene foam; that stuff is straight up nasty. It sometimes pays to offer to pay a little extra for better packing materials.
- Be aware that both US & international customs offices can sometimes delay shipments of pedals & rack electronics if there have been any recent bombings in the world. Yes, I've had a delay get delayed. Also, FWIW I've also had a compressor get compressed. Thanks UPS!
Other than that, I've had some really great overseas transactions. You can get some truly amazing things if you keep your eyes open.
