just to the point of why some fair number of perople won't ship out of the country....
1) extra paperwork to cover customs, and this paperwork seems to change every time I ship out of country. What is the correct ID number for used auto parts and what is really their country of origin again? Maybe Brazil, maybe USA, maybe Germany, maybe China, just for used guages?
2) Fed Ex, USPS, DHL, UPS, and the like all have different requirements for this that or what ever. And the requirements will differ from day to day and person to person at their shipping locations
3) hard or impossible to track
4) generally impossible to get a claim for damage or loss paid
5) generally impossible to prove receipt of item
6) declared value issues, where you sell something for say $100 and because of VAT or other taxes someone wants it declared as a sample or of no value...how do you suppose a claim would go for loss or damage of something you have declared as "no value"? Not to mention whose laws might have been violated?
I have shipped quite a few things internationally....it is not easy...hence some fair number of folks won't do it...
