It is not quite that simple. In 2021 new BEV incentives were promulgated. The specifics do include Road Tax exemptions and trade agreement modifications. Other local manufacturing and investment incentives also have a part. Hence the Tesla specifics undoubtedly have incentives for Superchargers, certainly with access to non-Tesla vehicles also, and Malaysia sourcing agreements can also yield benefits. In short the generic answers are not really relevant and thus for the Tesla specifics have not been disclosed.
Generically car import duties are 30% and local taxes 10%.
The whole Malay peninsula is now selling Tesla from Singapore, Malaysia and Thailand. The first two both import many used cars from Singapore and Japan, both of which retire cars at very young age. Not too far ahead similar markets should develop for Tesla and other BEV's but that will wait for major market penetration fo BEV in both countries. Later similar processes will begin in the Indian subcontinent. As we consider Tesla future development these issues will become relevant as will the huge needs for smaller passenger cars and minivans. The tuk-tuk market BEV market is thriving in India and Thailand, while China's growth is in micro-mini cars. Those need never be Tesla's market but their growth is now beginning to drive higher level demand.
Such considerations ar obviously part of today's issues. I'll wager there will be little discussion, primarily because North Americans are the largest audience and they think a Ford F150 is small, so they are incapable of understanding China , Indian subcontinent or the Malay peninsula. Elon does so they'll be a 'silent' part of the plan
We now wait for Indonesia, themselves anxious to have Tesla, plus Philippines. Logistically Indonesia and Philippines are challenging because they're made up of huge expanses of islands linked [almost] only by air and sea, making support exceedingly difficult. Still, Tesla is at the point of supporting nearly all accessible markets.
After Mexico and Sigma come all those wide-open South and Central American markets.
Within a few months we'll begin more Africa, rather than just Morocco tourist oriented Superchargers. South Africa beckons! Luckily MB, VAG are already nearly everywhere, as are parts of Stellantis.
