Roy,
I spent 30 years doing international shipping... I've shipped about everything you can imagine at one time or another to at least half the countries in the world... and I've had good and bad luck with most of them... South Africa is an interesting country to ship to... I had an oil field explosive shipment into So. Africa... got all my permits and such, shipped the explosives without a hitch.... but by U.S. regulations, the Detonator cord for the explosives had to be shipped separately... I had about 5,000 lbs of explosives on the ground in South Africa... they would not give me permits to ship the det cord... without the det cord, the explosives were useless... I spent 30 days and I don't know how many phone calls to my agent, to the ministries of every department I could think of to get my cord into So. Africa.... finally client said just ship it to Namibia.. we'll smuggle it in.
Brazil is another interesting country to ship to... I had a piece that was shipped from my warehouse in Houston to Rio.... the warehouse packed the wrong freight in the box or else mis-marked the box... once cleared into Brazilian customs, I could not retrieve the freight, they did not have facilities to change the paperwork to re-export the box....
I also lost an industrial paper cutter in Sao Paulo when I was working for a company in Tucson ... it was in a slatted crate that was 6' x 6' x 6', you could see the machine through the slats, it was shipped on a direct non-stop flight out of Miami to Sao Paulo on Varig Airlines, confirmed on board out of Miami and never cleared customs... I searched for that one for a month...finally had to file a freight claim... it was still pending when I left the company to go back to Houston.
