I get stuff shipped to me via various carriers. The key is packing and palletizing.
Bespoke shipping- the guy with the Halliburton case handcuffed to his wrist tends to cost. I once inquired about shipping jewelry- not something that is easily dealt with as a citizen, but the dealers know how to do it. I rely on DHL Express for records outside of the US--I typically get them in 5 days.
Ditto, Japanese post-priority. Fast.
But for gear, you have to take extra precautions. Part of it depends on the sender to do it right. When I had my old Quad Loudspeakers restored, Kent McCollum shipping me good packing, then arranged for UPS ground to pick them up-- the UPS guy palletized the packed boxes, and when Kent was done, they were shipped to my new location in Texas. Not a problem.
With Lamm, they use wooden shipping crates with custom foam. Require air freight. Thankfully, I have not had to do that- I used to be in NY metro and would drive them over to Vlad (RIP).
It can be done without issues. I had a friend who used to ship multi-sk-zillion vintage racing cars all over the world. Same deal- palletized, shipped as air freight. Lord only knows what that costs now, used to be 5k one way. You don't need to spend like that to ship a piece of gear, but packing and palletizing is key in my estimation.
