This is all good and well.
What you don’t explain is that none of these companies have stock of anything. None of them do.
They all get an order (online order from
Fücking Timbuktu) and order that said part from their local Toyota dealership authorized to sell factory Toyota service parts.
Every single company or person you deal with that sources parts outside of the US is merely a middle man for some other entity that is **authorized** to sell Toyota spare parts.
Unlike the US Toyota service parts system, the GCC/Oceania/SouthEast Asia and Japan operate on distributorship systems.
In the US, there are only two distributorships left extant: SET: SouthEast Toyota and GST: Gulf States Toyota:
Both of those entities have very discrete part pricing schemes in place that mirror TMNA (Toyota Motor North America) protocols mainly to maintain consistent public perception of service parts MSRP.
The companies you source your parts from outside of the US: They operate outside of ownership by TMC and are able to negotiate their own information system agreements (IE: inventory visibility/stock/days to fill part number from zero) as well as the obvious pricing and currency advantages certain regions have vs. US dollar.
Shipping costs are always negotiated locally based on volume: Nothing more, nothing less.
IMPEX is literally 3 dudes in a garage.

But more power to them to figure out perception. Same with a lot of these outfits.
None of them have any more information or access than anyone else.
The only people who really know are people who have access to the global Toyota parts master database. And only a few people have that access. And that database is Japan-based.
