The same thing is happening to me as we speak. I ordered an “expensive to me” pipe from a highly regarded Italian pipe shop (probably the same as OP). My item was denied clearance by US customs because I “might use the pipe to smoke illegal drugs.” Spent the better part of the week tracking down this information only to find out the pipe is being sent back to the shipper. No one cared to let me know. Now I’ve worked with this Italian company for years and will continue to do so because their prices and service (for the most part) is unmatched. I’ve never had this issue with them until now. I’ve been assured this is all being resolved. I was obsessing over this pipe for months, scratching up enough money to finally get it, now this. Looks like I’ll just have to wait a little longer. Somehow “the check cleared” already though...go figure!
